    WILKINSON, Circuit Judge:
    Appellant       Michelle      Nemphos           filed      suit        against      the
    manufacturers of bottled water, infant formula, and baby food
    that     her   minor    daughter       had        consumed      before        developing     a
    condition known as dental fluorosis. Nemphos brought an array of
    tort     and   fraud    claims      under     Maryland         law     against     appellee
    manufacturers      Nestlé     Waters    North          America,      Inc.,     Nestlé    USA,
    Inc., The Dannon Company, Inc., and Gerber Products Company. The
    question in this appeal is whether federal law, which provides
    uniform labeling standards for the products at issue, preempts
    Nemphos’s state-law claims. We hold that federal law preempts
    Nemphos’s bottled water claims and that her complaint as to the
    infant    formula      and   baby    food     products         fails     to    satisfy     the
    pleading requirements of Federal Rule of Civil Procedure 8(a)(2).
    We thus affirm the district court’s dismissal of her action.
    I.
    Because the district court dismissed Nemphos’s claims under
    Federal Rule of Civil Procedure 12(b)(6) for failure to state a
    claim,    we   review    legal      issues        de   novo    and     treat     the    facts
    alleged in the complaint as true. Bell Atl. Corp. v. Twombly,
    
    550 U.S. 544
    , 555-56 (2007); Neitzke v. Williams, 
    490 U.S. 319
    ,
    326-27 (1989).
    3
    A.
    Nemphos alleges that her minor daughter, C.G.N., consumed
    appellees’ products throughout her childhood. From her birth in
    1997    until    approximately       her    first       birthday,    C.G.N.       was    fed
    Nestlé’s     Carnation       Good    Start       infant       formula,     in    lieu    of
    breastfeeding. From approximately four months to one year of
    age, C.G.N. ate Gerber baby foods almost exclusively, including
    Gerber apple juice that was often mixed into her water. From
    approximately      six    months     to    eight    years      of   age,   C.G.N.       also
    habitually       drank    Nestlé’s       Poland    Spring       fluoridated       bottled
    water and Dannon’s Fluoride To Go bottled water.
    According    to    Nemphos,        C.G.N.    developed       dental      fluorosis
    from consuming the appellee manufacturers’ products.                            Although
    fluoridated       drinking       water    can    play     a    significant       role    in
    preventing tooth decay in children and adults, young children
    who consume too much fluoride may develop dental fluorosis -- a
    change in the appearance of tooth enamel. Nemphos’s complaint
    does not specify the precise extent of C.G.N.’s fluoride-related
    injuries, but symptoms may range from specks and discoloration
    of teeth in mild cases to mottling and pitting in more severe
    ones.
    Dental     fluorosis       results        when     young     children          ingest
    excessive fluoride over an extended period of time, while their
    adult    teeth    are    still    developing       below      the   surface      of   their
    4
    gums. To address that risk, federal agencies such as the Food
    and    Drug    Administration       (“FDA”)           issue        recommendations      and
    regulations for safe water fluoridation levels. The products at
    issue in this case are not alleged to have violated federal
    fluoride requirements.
    B.
    In   September     2012,     Nemphos       filed        a     complaint    on    her
    daughter’s behalf against the appellee manufacturers. Although
    all of Nemphos’s claims were based on Maryland law, she brought
    suit in federal district court because the parties are citizens
    of    different   states.    See    
    28 U.S.C. § 1332
    (a).        The    complaint
    alleged that      the    manufacturers          had    failed       to   warn   about   the
    risks of dental fluorosis for children who consume large amounts
    of    fluoride,   and    that     they     had    misleadingly           marketed      their
    fluoride-containing         products        as        especially         beneficial      to
    children.     Consequently,       the    complaint       maintained,        “C.G.N.     has
    suffered, and continues to suffer from, physical and emotional
    damages related to her injuries from fluoride, which include,
    but are not limited to, dental fluorosis.” J.A. 13. Nemphos’s
    complaint     asserted    six     causes    of        action    under     Maryland      law:
    strict liability (Count I), negligence (Count II), breach of
    implied     warranties    (Count        III),    fraud     (Count        IV),    negligent
    infliction of emotional distress (Count V), and violations of
    5
    the Maryland Consumer Protection Act, which prohibits unfair and
    deceptive     trade   practices       (Count   VI).    In    response,    appellees
    filed motions to dismiss the complaint under Rule 12(b)(6), for
    failure to state a claim upon which relief can be granted.
    The      district    court   granted      the     motions      and   dismissed
    Nemphos’s     complaint    with   prejudice.       The     court   concluded    that
    federal law preempted Nemphos’s state-law claims. The appellee
    manufacturers’ products were already subject either to a federal
    “standard of identity” or to other federal labeling regulations.
    Granting the relief requested by Nemphos, the court found, would
    have required appellees’ products to have fluoride levels below
    the FDA’s established limits or to bear warnings not mandated by
    the FDA. In other words, Nemphos sought to impose a duty under
    Maryland    law   that    was   not    identical      to    the   existing   federal
    requirements. 1 Nemphos now challenges the court’s dismissal of
    her suit. 2
    1
    Although the underlying merits of Nemphos’s state-law
    claims are not directly at issue in this appeal, as a
    substantive matter the district court’s opinion left open only
    her tort claims invoking strict liability (Count I) and
    negligence (Count II). Prior to the court’s decision, Nemphos
    had already conceded that Maryland law would not countenance an
    independent claim for negligent infliction of emotional distress
    (Count V). In its memorandum opinion, the court deemed all of
    Nemphos’s claims preempted, but it nevertheless proceeded to
    find that her claims regarding breach of implied warranties
    (Count III), fraud (Count IV), and Maryland Consumer Protection
    Act violations (Count VI) all failed under Maryland law. The
    (Continued)
    6
    II.
    Nemphos first argues that federal law does not preempt her
    state-law    claims     about    Nestlé’s        and    Dannon’s    bottled       water
    products.    Specifically,       she   alleges         that    Nestlé    and    Dannon
    failed to warn about the risks of dental fluorosis and engaged
    in misleading marketing. To assess the viability of Nemphos’s
    bottled   water    claims,      we   first     need     to    examine    the   federal
    statutory and regulatory framework, with particular attention to
    the relevant preemption structure. We will then consider her
    failure-to-warn and misleading-marketing claims.
    A.
    For more than a century, the FDA has been charged with
    protecting     Americans        against        foods     and     drugs     that     are
    “misbranded”      or   “adulterated.”          See     Federal   Food,    Drug,     and
    Cosmetic Act (“FDCA”), ch. 675, 
    52 Stat. 1040
     (1938); Pure Food
    Act, ch. 3915, 
    34 Stat. 768
     (1906); see 
    21 U.S.C. § 331
    . Today,
    a core element of the FDA’s mission is to “protect the public
    district court did not address the substance of Nemphos’s strict
    liability and negligence claims, nor did it need to do so.
    2
    Nemphos also seeks leave to amend her complaint on remand.
    Because we find her claims preempted, we likewise agree with the
    district court’s denial of Nemphos’s request on the ground that
    any amendment would be futile. See Fed. R. Civ. P. 15(a); Foman
    v. Davis, 
    371 U.S. 178
    , 182 (1962); Laber v. Harvey, 
    438 F.3d 404
    , 426 (4th Cir. 2006) (en banc).

    health    by     ensuring          that     . . .        foods    are       safe,     wholesome,
    sanitary, and properly labeled.” 
    21 U.S.C. § 393
    (b)(2)(A). The
    states    have       also    played       important          roles      in    food     and    drug
    regulation       since      the    time     when      they    were    only     colonies.       See
    Wallace F. Janssen, America’s First Food and Drug Laws, 
    30 Food Drug Cosm. L.J. 665
     (1975). Even as federal laws remain supreme,
    U.S. Const. art. VI, cl. 2, the United States has developed a
    dual    system       of   food     and    drug       regulation.        A    federal    law    may
    preempt state intervention in one aspect of a given food, for
    example, while allowing states to act on other aspects of the
    same     food.       Lofty    questions          about       federal-state            relations,
    however, are not urged upon us in this appeal, and our ruling
    does not disturb the balance that has been carefully struck over
    the    years.    This       case    turns     on     a    relatively         narrow    issue    of
    statutory interpretation.
    The federal Nutrition Labeling and Education Act of 1990
    (“NLEA”), Pub. L. No. 101-535, 
    104 Stat. 2353
    , secures the FDA’s
    authority       to    oversee        food    labeling.           In   passing         the    NLEA,
    Congress underscored its intent “to clarify and to strengthen
    the Food and Drug Administration’s legal authority to require
    nutrition labeling on foods, and to establish the circumstances
    under which claims may be made about nutrients in foods.” H.R.
    Rep. No. 101-538, at 7 (1990), reprinted in 1990 U.S.C.C.A.N.
    3336, 3337. The NLEA builds on the FDCA to develop a nationwide
    8
    system of uniform nutrition labeling for covered foods, in part
    by   requiring     meaningful       disclosures         about    certain      nutrients
    contained in those foods. Id.; see 
    21 U.S.C. §§ 343
    , 343-1.
    The   uniform       labeling    system      instituted       by    the   FDCA    and
    fortified by the NLEA benefits both manufacturers and consumers
    of food products. See 
    21 U.S.C. § 341
    ; POM Wonderful LLC v.
    Coca-Cola Co., 
    134 S. Ct. 2228
    , 2234, 2238-40 (2014); 62 Cases
    of Jam v. United States, 
    340 U.S. 593
    , 596 (1951); Fed. Sec.
    Adm’r v. Quaker Oats Co., 
    318 U.S. 218
    , 230-31 & n.7 (1943).
    Manufacturers      can    produce    and       market    foods    consistently        and
    cost-effectively     across       the    United    States.       Consumers      gain   a
    reliable     and     comprehensible            means      of     ascertaining         the
    nutritional content of the foods they buy, wherever they may
    live or travel in this country. Armed with such information,
    consumers can make well-informed decisions about the types and
    quantities of ingredients in their diets.
    B.
    A   system    engineered       to   ensure        national    uniformity        must
    exclude some local disuniformities. While the NLEA provides a
    nationwide   framework      for     certain      types    of     food   labeling,      it
    likewise prohibits states from disrupting that arrangement with
    nonidentical requirements. The Act struck a necessary balance
    between the two fonts of regulatory authority -- between uniform
    9
    federal labeling standards and potentially more stringent laws
    in    individual     states.       As   the      FDA    has     explained,       “Congress
    decided that even though Federal requirements may preempt more
    restrictive      State   requirements         in      certain    instances,       the   net
    benefits from national uniformity in these aspects of the food
    label outweigh the loss in consumer protection that may occur as
    a    result.”    State   Petitions         Requesting      Exemption      from     Federal
    Preemption, 
    58 Fed. Reg. 2462
    , 2462 (Jan. 6, 1993).
    To maintain that balance, the NLEA includes a series of
    express     preemption      provisions.          
    21 U.S.C. § 343-1
    (a)(1)-(5).
    These     provisions     --        under    the        heading       “National     uniform
    nutrition       labeling”     --    forbid       states       from    establishing      any
    requirement that is “not identical to” the federal requirements
    in five areas of food labeling. 
    Id.
     One of those areas, and the
    one at issue in Nemphos’s bottled water claims, concerns the
    “standard of identity.” 
    Id.
     § 343-1(a)(1).
    This preemption provision, subsection (a)(1), provides as
    follows:
    (a) Except as provided in subsection (b) of this
    section, no State or political subdivision of a State
    may   directly  or   indirectly establish  under  any
    authority or continue in effect as to any food in
    interstate commerce --
    (1) any requirement for a food which is the
    subject of a standard of identity established
    under section 341 of this title that is not
    identical to such standard of identity or that is
    not identical to the requirement of section
    10
    343(g) of this title, except that this paragraph
    does not apply to a standard of identity of a
    State or political subdivision of a State for
    maple syrup that is of the type required by
    sections 341 and 343(g) of this title . . . .
    Id.; see also NLEA § 6(c)(1), 104 Stat. at 2364, reprinted in 
    21 U.S.C. § 343-1
    , at 87 (specifying that the NLEA preempts state
    law only expressly). Several contextual points help to clarify
    this language. First, § 341 empowers the FDA to establish “a
    reasonable definition and standard of identity” for almost any
    food.   Id.     § 341.   Second,       § 343(g)     deems   a   food        product
    “misbranded” if it is represented as a particular food yet fails
    to conform to the standard of identity. Id. § 343(g). Third,
    subsection (a)(1) allows a conspicuous exception to preemption
    for but a single product: maple syrup. Id. § 343-1(a)(1). Last,
    § 343-1(b) enables the FDA, “[u]pon petition of a State or a
    political     subdivision,”       to   exempt     certain   state      or    local
    requirements that would otherwise be barred by subsection (a)(1)
    or the four other preemption provisions. Id. § 343-1(b).
    Within     this   context,    the    force   of   subsection   (a)(1)       is
    apparent.     First,   the   statute     preempts   “any”   applicable        state
    requirement, not just some of them. Id. § 343-1(a)(1). Second,
    the statute preempts any nonidentical state requirement for a
    “food” that is the subject of a federal standard of identity;
    that is, the preempted requirement may be any conflicting state-
    law obligation for that food. Id. Third and finally, subsection
    11
    (a)(1)   uses       the    unequivocal          phrase      “not    identical      to”    the
    standard of identity. Id. It does not say any state requirement
    merely     “differing           from,”     “conflicting        with,”      “inconsistent
    with,” or “dissimilar to” the federal requirement. Nor does the
    statute employ here the more limited phrase “in violation of” --
    as it does regarding the petition process, later in the same
    section.      Id.     § 343-1(b).             The    four     subsequent         preemption
    provisions use the same “not identical to” phrasing toward other
    categories of labeling requirements. Id. § 343-1(a)(2)-(5). Put
    simply, then, we can understand subsection (a)(1) this way: for
    a food that is the subject of a federal standard of identity,
    this provision preempts any pertinent state requirement that is
    not identical to the federal requirement. Id. § 343-1(a)(1).
    The NLEA does afford a specific exception to its preemption
    provisions      --        for    state-generated            “safety”      warnings.       The
    preemption      provisions          in     § 343-1       do    not       “apply    to     any
    requirement respecting a statement in the labeling of food that
    provides for a warning concerning the safety of the food or
    component     of     the    food.”       NLEA    § 6(c)(2),        104   Stat.    at     2364,
    reprinted in 
    21 U.S.C. § 343-1
    , at 87. In the context of food
    additives, the FDA defines “safety” as entailing “a reasonable
    certainty     in     the        minds    of     competent      scientists         that    the
    substance is not harmful under the intended conditions of use.”
    
    21 C.F.R. § 170.3
    (i).          Establishing        “complete        certainty”       of
    12
    “absolute harmlessness” is not required. 
    Id.
     Although the NLEA’s
    preemption       provisions          sweep    broadly,    state-law         duties       may    be
    insulated        from     the    Act’s       preemptive     reach      if    they    involve
    warnings about food “safety.”
    C.
    A     standard            of       identity        specifies          the      defining
    characteristics of a given food. 
    21 U.S.C. § 341
    ; see also 
    id.
    § 343(g). To “promote honesty and fair dealing in the interest
    of    consumers,”         the         FDCA    allows     the     FDA    to        “promulgate
    regulations        fixing       and    establishing       for   any    food,       under       its
    common     or     usual     name       so    far    as   practicable,        a    reasonable
    definition and standard of identity,” as well as standards of
    quality and fill. Id. § 341. This power to determine standards
    of identity -- in essence, to regulate the ingredients of a food
    and   its       representation          in   interstate        commerce      --     is    “far-
    reaching.” 62 Cases of Jam, 
    340 U.S. at 598
    .
    The standard of identity is important to the FDA’s capacity
    to regulate those characteristics of a food label that would
    enable a food to be marketed as such, and to ensure that certain
    foods     accord    with        consumer     expectations.       Specifically,           to     be
    marketed in interstate commerce under a given name -- such as
    “bottled     water”       --     a    food    must   conform     to    the       standard       of
    identity. See 
    21 U.S.C. §§ 331
    , 341, 343(g); 62 Cases of Jam,
    13
    
    340 U.S. at 598
    ; see also 
    21 C.F.R. § 101.3
    . At the consumer
    level, a standard of identity warrants that individuals will
    encounter a label reflecting the food’s actual contents -- that
    consumers “will get what they may reasonably expect to receive.”
    Quaker Oats, 
    318 U.S. at 232
    . Significantly, the FDA may also
    distinguish “optional ingredients” that manufacturers can add to
    a food that is subject to a standard of identity. 
    21 U.S.C. §§ 341
    , 343(g). Any optional ingredients present must be “named
    on the label.” 
    Id.
     § 341; see id. § 343(g).
    Although the details vary from food to food, fundamentally
    the standard of identity focuses on the contents of a food and
    the way those contents are represented to consumers. Under the
    NLEA’s amendments, the FDA now establishes standards of identity
    through the agency’s conventional rulemaking process. 
    21 U.S.C. § 371
    ; 
    21 C.F.R. § 10.40

    Administration     § 10:29    &     n.8        (3d    ed.     2014).    Standards     of
    identity    have    been     utilized           to     delineate        the     accepted
    composition of a food, to indicate permissible formulations or
    varieties   of     ingredients,      to        note        optional    or     prohibited
    ingredients, to describe appropriate manufacturing processes, to
    detail methods of product analysis, to designate a commercial
    name, to set ingredient-related labeling requirements. See 21
    C.F.R.   pts.    130-169;    see,    e.g.,           id.    § 131.110       (milk);   id.
    § 131.200   (yogurt);       id.     § 137.105           (flour);       id.     § 139.110

    (macaroni      products);       id.     § 145.110         (canned     applesauce);      id.
    § 150.160      (fruit      preserves     and       jams);    id.    § 155.190       (canned

    chocolate); id. § 169.140 (mayonnaise). In addition to various
    descriptive provisions, a “label declaration” regarding a food’s
    ingredients often appears in these regulations. See, e.g., id.
    §§ 131.110(f),             137.105(b)(1),           139.110(g),           145.110(a)(4),
    150.160(e)(2),             155.190(a)(6),            155.130(a)(5),           163.130(d),
    169.140(f).
    The FDA regulates bottled water as a food, and the agency
    has    developed      a    standard     of     identity      for    bottled    water.   
    21 C.F.R. § 165.110
    ; see also Beverages: Bottled Water, 
    60 Fed. Reg. 57,076
    , 57,076 (Nov. 13, 1995) (noting that the FDA had
    received some 430 responses to the proposed standard during the
    comment period). Under the FDA’s standard of identity, “bottled
    water”    is     defined      as      “water       that    is   intended      for    human
    consumption and that is sealed in bottles or other containers
    with no added ingredients except that it may optionally contain
    safe   and     suitable      antimicrobial         agents.”     
    Id.
          § 165.110(a)(1).
    The standard of identity also classifies fluoride as an optional
    ingredient in bottled water. Id. Manufacturers may add fluoride
    to bottled water within the limitations established in the FDA’s
    “standard       of        quality”      for        bottled      water,      which     sets
    microbiological,             physical,          chemical,          and       radiological
    15
    specifications.          Id.;     see    id.    § 165.110(b)(2)-(5)             (standard         of
    quality);      id.        § 165.110(b)(4)(ii)               (fluoride          levels).          The
    specific concentration of fluoride permitted depends on what the
    retail      location’s         average    maximum          daily      air    temperature         is,
    whether the bottled water is packaged domestically or imported,
    and      whether              fluoride     has            been        added.         See         id.
    § 165.110(b)(4)(ii)(A)-(D).               If    fluoride         or    any    other       optional
    ingredient has been added to the bottled water, the label must
    list   each    of       the     ingredients.         Id.    §§ 101.4(a)(1),              130.3(e),
    165.110(a)(4).
    Nemphos      attempts       to    ascribe      a     very      restrictive         role    to
    standards of identity, claiming flatly that “Federal Standards
    of Identity . . . Do Not Address Warnings.” Appellant’s Reply
    Br.    at    12;        see     Appellant’s       Br.       at     36.      Aside        from    the
    incorrectness of this statement as a general matter, the FDA’s
    regulations        do    specifically          indicate      when        manufacturers          must
    provide      warnings           about     fluoride          in     bottled       water.          Id.
    § 165.110(c). If the level of fluoride surpasses the specified
    maximum       concentration,             the         bottled          water         is      deemed
    “substandard.” Id. § 165.110(c); see also id. § 130.14(a). The
    label must then state “Contains Excessive Fluoride” or “Contains
    Excessive Chemical Substances.” Id. § 165.110(c)(3).
    In establishing the standard of identity for bottled water
    in 1995, the FDA actually addressed several issues involved in
    16
    fluoride      consumption,     including      the      notion       of     a     warning
    requirement regarding dental fluorosis. 60 Fed. Reg. at 57,079-
    80. The FDA recognized that “an advisory statement . . . may be
    appropriate to prevent unwanted aesthetic effects from excessive
    doses of fluoride,” and it even “encourage[d] manufacturers to
    provide such information to consumers, especially on products
    labeled for infant use.” Id. at 57,080. Nevertheless, the FDA
    declined to mandate a warning in the standard of identity about
    the   risks    of   dental    fluorosis.      In    fact,     the    FDA       had    set
    acceptable     fluoride     levels    for    bottled      water     --   which       were
    consistent      with   levels        established       by    the     Environmental
    Protection Agency and the Surgeon General -- and it had required
    substandard bottled water to indicate excessive fluoride content
    on the label. Id.; see 
    21 C.F.R. §§ 165.110
    (b)(4)(ii), (c). The
    agency   accordingly      found   “no    basis”     to    follow     one       comment’s
    suggestion “to require an advisory statement concerning infant
    fluoride consumption on bottled waters containing 0.3 [parts per
    million (‘ppm’)] or more fluoride.” 60 Fed. Reg. at 57,080. Such
    water, after all, would not be substandard. The FDA’s fluoride
    limits for domestic bottled water range from 0.8 to 1.7 ppm when
    fluoride has been added, and from 1.4 to 2.4 ppm when only
    naturally       occurring      fluoride       is         present.        
    21 C.F.R. § 165.110
    (b)(4)(ii)(A), (C). In effect, the proposal rejected by
    the FDA would have reduced the threshold for a fluoride-related
    17
    warning dramatically, from between 0.8 and 2.4 ppm to just 0.3
    ppm. 3
    D.
    The    preemption          structure      under     the     NLEA       is    highly
    “complex,” POM Wonderful, 
    134 S. Ct. at 2238
    , but it also forms
    the framework for evaluating Nemphos’s claims. Reduced to its
    essence, the FDCA and NLEA convey significant powers to the FDA
    to regulate food safety. This statutory charge reflects the all-
    around       benefits    of     uniform    food     labeling.       One    of   the    FDA’s
    crucial        tools    in    its    regulatory      effort    is    the    standard     of
    identity.       
    21 U.S.C. § 341
    .    The      express   preemptive         force   of
    § 343-1 allows federal regulations such as a food’s standard of
    identity         to     prevail        over        certain     nonidentical           state
    requirements. Id. § 343-1(a); NLEA § 6(c)(1), 104 Stat. at 2364.
    The FDA regulates bottled water as a food and has promulgated a
    standard of identity for it. 
    21 C.F.R. § 165.110
    . The parties do
    not dispute the FDA’s capacity to regulate bottled water in this
    way -- they disagree whether Nemphos’s state-law claims about
    fluoridated bottled water are preempted.
    3
    Milligrams per liter, used in the FDA’s bottled water
    regulations, is a roughly equivalent measure to parts per
    million. See, e.g., 5 Principles and Practices of Water Supply
    Operations: Basic Science Concepts and Applications 103 (4th ed.
    2010).
    18
    To summarize further, fluoride has been the subject of a
    great deal of discussion and regulation by the FDA. The agency
    has   set    a    range    of     permissible      fluoride      levels    for   bottled
    water.      
    Id.
        §§ 165.110(a)(1),         165.110(b)(4)(ii).           Manufacturers
    may optionally add fluoride to bottled water so long as the
    concentration does not exceed the levels stipulated by the FDA.
    Id. § 165.110(a)(1). If those regulatory ceilings are breached,
    the   manufacturer         must    place    a     warning   on    the    label    stating
    “Contains        Excessive      Fluoride”    or    “Contains      Excessive      Chemical
    Substances.”        Id.    § 165.110(c)(3).          But    the    FDA    requires     no
    particular warning regarding dental fluorosis. 60 Fed. Reg. at
    57,080.
    Finally, Nemphos does not allege that appellees’ bottled
    water     products        contained    fluoride       concentrations        above    the
    thresholds set by the FDA. She contends instead that federal
    statutes and regulations do not preempt her state-law claims.
    III.
    A.
    As part of her claims about Nestlé’s and Dannon’s bottled
    water, Nemphos maintains that the manufacturers failed to warn
    consumers about the risks of dental fluorosis. But for a food
    such as bottled water that is “the subject of a standard of
    identity,” the NLEA preempts any state “requirement” that is
    19
    “not       identical        to”    the    federal       standard.          
    21 U.S.C. § 343
    -
    1(a)(1).
    The term “requirement” in the NLEA’s preemption provisions
    must       be     read      broadly.      It     includes          statutes,          regulations,
    standards, and other obligations arising from state law. See 
    21 C.F.R. § 100.1
    (b)(5). In comparable contexts, the Supreme Court
    has    repeatedly         instructed       that       state       “requirements”            encompass
    not     only       positive        enactments      from       the     legislature            or     the
    executive,          but     also     common-law        rules        and      duties         from    the
    judiciary.         See    Riegel     v.    Medtronic,         Inc.,       
    552 U.S. 312
    ,    324
    (2008)       (“Absent        other       indication,          reference          to     a     State’s
    ‘requirements’ includes its common-law duties.”); Bates v. Dow
    Agrosciences LLC, 
    544 U.S. 431
    , 443 (2005); Cipollone v. Liggett
    Grp., Inc., 
    505 U.S. 504
    , 521 (1992). There is no indication
    here       that    § 343-1(a)        distinguishes           among     different            types    of
    state       obligations.           Nor    does        the     preemption          provision          in
    subsection (a)(1) fence off certain foods or certain aspects of
    the standard of identity -- with the one exception of maple
    syrup.       
    21 U.S.C. § 343-1
    (a)(1).           To     the     extent      that        Nemphos
    requests          damages    rather       than    explicitly          demanding         a     warning
    requirement,         the     analysis      remains          the    same. 4      However       Nemphos
    4
    Assuming arguendo that the district court correctly
    concluded that the only even potentially meritorious state-law
    claims were Nemphos’s strict liability and negligence claims,
    (Continued)
    20
    frames    her    failure-to-warn        claim,      granting     her    relief    would
    impose a “requirement” in the form of a warning under Maryland
    law.
    Moreover,    Nemphos’s       proposed       “requirement”       would     not   be
    “identical” to the FDA’s standard of identity. 
    Id.
     The statutory
    phrase “not identical to,” according to the FDA’s definition,
    “means that the State requirement directly or indirectly imposes
    obligations or contains provisions concerning the composition or
    labeling of food, or concerning a food container,” that either
    “[a]re not imposed by or contained in,” or “[d]iffer from,” the
    applicable federal regulations. 
    21 C.F.R. § 100.1
    (c)(4)(i)-(ii).
    Nonidentical       state       requirements,              whatever     their      legal
    provenance, are preempted. In each of the areas selected for
    preemption,      such   as    the     standard      of     identity    in   subsection
    (a)(1),    the     NLEA      sought    to        ensure     a   nationally     uniform
    regulatory system, rather than a fifty-state patchwork.
    Federal law already covers the ground that Nemphos aims to
    unsettle through her claims. She seeks a required warning that
    is additional to and certainly “not identical to” the federal
    see supra note 1, the case law is equally clear. The Supreme
    Court has specifically found that common-law causes of action
    for   strict   liability    and   negligence   constitute  state
    “requirements” subject to preemption. See Riegel, 
    552 U.S. at 323-24
    . Assigning liability and awarding damages, after all, may
    be “a potent method of governing conduct and controlling
    policy.” 
    Id. at 324
     (internal quotation marks omitted).

    standard. The FDA’s standard of identity reaches warnings, and
    it    does    not    demand       a    warning      about    dental       fluorosis.     The
    standard of identity for bottled water stipulates, for example,
    that bottled water intended for infants that is not commercially
    sterile must bear this conspicuous statement on the label: “Not
    sterile. Use as directed by physician or by labeling directions
    for use of infant formula.” 
    21 C.F.R. § 165.110
    (a)(3)(iii). Yet
    when fluoride is present within accepted levels, the standard of
    identity demands merely that the label list fluoride among the
    ingredients.              
    Id.
             § 165.110(a)(1),             (4);       see        id.
    § 165.110(b)(4)(ii). If the bottled water contains fluoride in
    concentrations beyond those permissible levels, only then must
    the   label    bear       the    warning    “Contains       Excessive       Fluoride”     or
    “Contains Excessive Chemical Substances.” Id. § 165.110(c)(3).
    The parties do not dispute, however, that the fluoride levels in
    Nestlé’s and Dannon’s bottled water satisfied federal limits.
    The    presence       of    an    express     preemption       clause    “does     not
    immediately         end    the    inquiry       because      the     question       of   the
    substance and scope of Congress’ displacement of state law still
    remains.” Altria Grp., Inc. v. Good, 
    555 U.S. 70
    , 76 (2008). But
    Nemphos’s     claims       do    not    fall   into    a    gray    area.    The    warning
    requirement Nemphos seeks is simply not identical to the FDA’s
    22
    existing         standard       of    identity.        As   such,      her    failure-to-warn
    claim is preempted. 5
    B.
    In    the        other   part    of    her      bottled   water        claims,      Nemphos
    asserts          that     Nestlé       and    Dannon        misleadingly           marketed       and
    advertised          their       fluoridated            bottled      water          products        as
    especially beneficial to children. But this misleading-marketing
    claim is essentially the same as her failure-to-warn claim --
    albeit       dressed       in   different         clothing.      The     NLEA      preempts       any
    state       “requirement”            that    is   “not      identical        to”    the    federal
    standard of identity for a food such as bottled water. 
    21 U.S.C. § 343-1
    (a)(1). The preemption provision encompasses the labels
    affixed to a bottle as well as the contents inside. It makes no
    exception for marketing or advertising in areas regulated by the
    FDA.       The    misleading-marketing             claim     thus   fails          for    the   same
    reason       as     the     failure-to-warn             claim.      It       would       impose    a
    5
    As noted, the NLEA also contains an exception to
    preemption for “safety” warnings. NLEA § 6(c)(2), 104 Stat. at
    2364. This subsection instructs that the statute’s preemption
    provisions “shall not be construed to apply to any requirement
    respecting a statement in the labeling of food that provides for
    a warning concerning the safety of the food or component of the
    food.” Id. While the NLEA thus expressly preserves an important
    role for the states when it comes to safety warnings, Nemphos
    has failed to press arguments relevant to the “safety exception”
    and   appears  to   have   conceded   its  inapplicability.  See
    Appellant’s Reply Br. at 27-28; Oral Arg. at 1:49. As such, we
    see no need to address the matter here.
    23
    requirement      under    state     law       that   diverges       from      the    federal
    standard. As such, it would oblige Nestlé and Dannon to issue
    warnings about the risks of dental fluorosis for their products
    in the state of Maryland, even though the FDA resolved not to
    take that same step.
    Nemphos’s       restrictive         conception        of     the     standard         of
    identity     simply      fails     to     square      with       the     statutory         and
    regulatory structure. A standard of identity does center on the
    characteristics of the regulated food. See supra Section II.C.
    The   standard    of     identity       for    bottled      water      thus     prescribes
    accepted fluoride levels for the bottle’s contents. 
    21 C.F.R. § 165.110
    (a)(1); see 
    id.
     § 165.110(b)(4)(ii). But the statutory
    reach extends to labeling as well. See supra Section II.C. In
    particular,      it    regulates     labeling        that     appears      outside         the
    bottle. The standard of identity for bottled water, for example,
    governs label statements about mineral content, sourcing from a
    community      water        system,            and    sterility.              
    21 C.F.R. § 165.110
    (a)(3)(i)-(iii).           It     further       requires        the       label    to
    announce each of the ingredients contained in the bottled water
    if    any   ingredient,     such     as       fluoride,      has    been       added.      
    Id.
    § 165.110(a)(4); see id. § 101.4(a)(1). The FDA also demands an
    array of other label statements for bottled water of substandard
    microbiological, physical, chemical, or radiological quality --
    24
    including      the    “Contains      Excessive         Fluoride”        or    “Contains
    Excessive Chemical Substances” warning. Id. § 165.110(c)(1)-(4).
    Beyond the standard of identity in particular, the pattern
    in the broader statutory and regulatory structure makes this
    point    clear.       The     four   other      NLEA     preemption           provisions
    specifically involve food labeling, 
    21 U.S.C. § 343-1
    (a)(2)-(5),
    and all five are inscribed under the heading “National uniform
    nutrition      labeling,”      
    id.
       § 343-1.    The     FDA’s     own       regulations
    confirm this assessment: the preemption provisions cover state-
    law    requirements     “concerning      the    composition        or    labeling      of
    food” that are not identical to applicable federal regulations.
    
    21 C.F.R. § 100.1
    (c)(4). Food composition and food labeling are
    handled in tandem.
    Given   that    the    standard   of     identity     embraces         labeling,
    Nemphos would need to identify an exception to subsection (a)(1)
    for marketing or advertising. After all, “[e]very labeling is in
    a sense an advertisement.” Kordel v. United States, 
    335 U.S. 345
    , 351 (1948). But there is no such exception. By statute, the
    term “labeling” in this context carries a distinct meaning: it
    includes    “all     labels    and   other     written,    printed,          or   graphic
    matter,” whether “upon any article or any of its containers or
    wrappers” or “accompanying such article.” 
    21 U.S.C. § 321
    (m)(1)-
    (2).
    25
    The labeling requirements in the FDA’s standard of identity
    for bottled water already address fluoride content. As noted
    earlier, the FDA found “no basis” for a mandatory warning about
    dental    fluorosis          and       instead          left        that     option          to     the
    manufacturers.        60     Fed.      Reg.        at     57,079-80.          Carving         out     a
    preemption     exception          to    subsection         (a)(1)          for     marketing         or
    advertising,         when    the       FDA    has        already           made     an       explicit
    determination about fluoride-related labeling, would be not only
    inconsistent but also potentially confusing. The FDA’s standard
    of identity regulates what manufacturers must say about fluoride
    content   on    labels       or    other      visual       materials          on,       around,      or
    accompanying bottled water. 
    21 C.F.R. § 165.110
    (a), (c); see 
    21 U.S.C. § 321
    (m). Those are, needless to say, prime areas for
    marketing      and     advertising.           To        allow       a     nonidentical            state
    requirement to contravene the FDA’s approach in this area would
    undermine the NLEA’s preemption framework. Without this system
    of   preemption,       a    manufacturer           might       be       whipsawed       by    federal
    regulations      delineating           permissible              labeling          and     state-law
    claims of impermissibility. In the five areas designated by the
    NLEA, preemption shields manufacturers from that predicament. 
    21 U.S.C. § 343-1
    (a)(1)-(5). For the foregoing reasons, Nemphos’s
    misleading-marketing claim is preempted.
    In reaching this conclusion, we do not suggest that § 343-
    1(a)(1)   preempts          all    nonidentical           marketing          and        advertising
    26
    requirements, even where those requirements are wholly unrelated
    to packaging and labeling. For example, a state-law requirement
    that    bottled   water        manufacturers        provide    warnings      regarding
    dental    fluorosis     in     other    media       of    advertising       presents   a
    different question from the one before us today. Because Nemphos
    limits her marketing and advertising allegations to claims made
    on labeling and packaging, we need not reach the question of
    whether state-law requirements for out-of-store advertising and
    promotions would be preempted. Those matters are not before us,
    and we express no opinion on them.
    IV.
    Nemphos also requests relief based on Nestlé’s and Gerber’s
    labeling     of   their      respective       infant      formula   and     baby   food
    products, which did not provide a warning about the risks of
    dental fluorosis. Nemphos has now filed three versions of her
    complaint.    Even    her      latest   amended       complaint,      however,     still
    falls    short     of     stating       a        plausible    failure-to-warn          or
    misleading-marketing claim under federal pleading standards.
    Federal Rule of Civil Procedure 8(a)(2) requires that a
    complaint    contain      “a   short    and       plain   statement    of    the   claim
    showing that the pleader is entitled to relief.” Fed. R. Civ. P.
    8(a)(2). As the Supreme Court has explained in the context of
    motions to dismiss, “the pleading standard Rule 8 announces does
    27
    not require ‘detailed factual allegations,’ but it demands more
    than        an         unadorned,          the-defendant-unlawfully-harmed-me
    accusation.”         Ashcroft      v.     Iqbal,       
    556 U.S. 662
    ,    678     (2009)
    (quoting Bell Atl. Corp. v. Twombly, 
    550 U.S. 544
    , 555 (2007)).
    Unlike       with   her   bottled     water          claims,    Nemphos    does    not
    allege that the appellee manufacturers added fluoride to the
    infant formula or baby food products consumed by her daughter.
    Nor    does    she     allege    that     Nestlé       or    Gerber    violated      federal
    regulations. Food additives generally are presumed unsafe until
    approved by the FDA, and the agency regulates the conditions
    under which approved additives may be used safely. 
    21 U.S.C. §§ 321
    (s),       348(a).     The    FDA     in    fact       forbids    the    addition    of
    fluoride       to    any   foods    other    than       bottled       water,   unless     the
    addition results from using fluoridated public water supplies.
    
    21 C.F.R. § 170.45
    . Although manufacturers may not add fluoride
    to infant formula or baby food, some fluoride may nevertheless
    be present in the final product because of municipal water used
    in the manufacturing process. Nemphos’s concern thus involves
    the failure to warn that fluoride -- even at permissible levels,
    without       any    addition      by   manufacturers          --     may   contribute     to
    causing dental fluorosis over time.
    To     impose    on   manufacturers         a    duty    to     warn    under    these
    circumstances, Maryland law would oblige Nemphos to allege a
    good deal more than she has put forward in this action. The
    28
    complaint          is   studded         with    highly       general       and    conclusory
    statements that could be adapted to many different products at
    many different times. It says little about the contents of the
    infant       formula       and   baby    food    products         in    particular,    except
    merely that they contain some amount of fluoride. We are left
    essentially with a “naked assertion” of liability that lacks the
    “further factual enhancement” demanded by Rule 8(a)(2). Twombly,
    
    550 U.S. at 557
    .     Even    at     this    stage      of    the     proceedings,
    something more is required regarding the precise nature of the
    state-law duty the manufacturers are alleged to have breached,
    as    well    as     the    grounding      in    state      law    for    whatever    warning
    Nemphos proposes to impose. The vagueness of the allegations
    simply fails to satisfy the basic “plausibility” requirements of
    Rule 8 and Twombly, and it provides an inadequate basis for
    overturning the trial court’s dismissal of the infant formula
    and baby food claims.
    “Local Rule 103.6 of the District of Maryland requires that
    a party requesting leave to amend provide a copy of the proposed
    amendment to the court.” Francis v. Giacomelli, 
    588 F.3d 186
    ,
    197 (4th Cir. 2009). Nemphos, like the plaintiffs in Francis,
    did not file a separate motion requesting leave to amend her
    complaint       or      attach     a     proposed          amended      complaint     to   her
    opposition brief. We are therefore compelled to find that the
    district       court       did    not    abuse       its    discretion      in    dismissing
    29
    Nemphos’s third amended complaint with prejudice and denying her
    a fourth bite at the apple.
    V.
    For the foregoing reasons, the judgment is affirmed.
