SUMMARY**
Food, Drug, and Cosmetic Act/Preemption
The panel reversed the district court’s dismissal on
preemption grounds of a putative class action brought
against ProSupps USA under California consumer
protection laws for mislabeling a dietary supplement named
Hydro BCAA.
Plaintiff alleged that Hydro BCAA was mislabeled
because his preliminary testing found that the supplement
contained more grams of carbohydrates and calories than
was listed on the supplement’s FDA-prescribed
label. Plaintiff alleged he tested the supplement using the
FDA’s testing methods, but not the FDA’s twelve-sample
sampling process. The district court found that the Food,
Drug, and Cosmetic Act preempted the claims because
plaintiff failed to plead that he tested the supplement
according to the FDA’s sampling process.
The Food, Drug, and Cosmetic Act preempts state laws
imposing labeling requirements that are not identical to those
of the Act. Consumers can bring claims under state law
alleging that foods are mislabeled, but those claims cannot
impose liability beyond what the Act requires. If a product’s
label complies with the Act, then the Act preempts any state-
law claim that the product is mislabeled.
The panel held that plaintiff’s complaint allowed a court
to draw a reasonable inference that ProSupps misbranded the

supplement under the Act. Although plaintiff did not allege
that he complied with the FDA’s twelve-sample sampling
process, his preliminary testing of one sample, by an
independent laboratory using the FDA-prescribed process,
found that the supplement contained more carbohydrates and
calories than ProSupps listed on the supplement’s label. It
was plausible that additional samples would show similar
results. A court could therefore draw a reasonable inference
that testing a composite sample according to FDA
regulations would show that the supplement was misbranded
under the Act. Accordingly, plaintiff’s complaint survived
preemption on a motion to dismiss.

OPINION
JOHNSTONE, Circuit Judge:
Under the Food, Drug, and Cosmetic Act, a food’s label
must display certain nutritional information, including the
amounts of carbohydrates and calories in the food. This
information appears in what consumers know as the
“Nutrition Facts” panel. The Food and Drug Administration
(“FDA”) specifies testing methods for determining the
amount of carbohydrates and calories in a food. The FDA
also mandates a sampling process for those tests. That
process requires applying one of the specified testing
methods to a composite of twelve randomly chosen samples.
Generally, a food, including a dietary supplement, is
“misbranded” in violation of the Act if its label differs by a
specified margin from the results of these tests. The FDA
also allows foods containing up to 0.5 grams of
carbohydrates to be labeled as zero-carbohydrate, and foods
containing up to 5 calories to be labeled as zero-calorie. The
Act preempts state laws imposing labeling requirements that
are not identical to those of the Act. So consumers can bring
claims under state law alleging that foods are mislabeled, but
those claims cannot impose liability beyond what the Act
requires.
ProSupps USA LLC (“ProSupps”) sells a dietary
supplement named Hydro BCAA. The supplement’s FDA-
prescribed label states that each 13.8-gram serving contains
10 grams of amino acids but zero grams of carbohydrates
and zero calories. Based on this label, Jacob Scheibe bought
the supplement to help him lose weight and gain muscle
mass. Now he alleges that the supplement’s zero-
carbohydrate and zero-calorie claims were too good to be
SCHEIBE V. PROSUPPS USA, LLC 5
true. His preliminary testing found that the supplement
contained 5.68 grams of carbohydrates and 51 calories per
serving, far exceeding the FDA’s allowable margins for
zero-carbohydrate and zero-calorie labeling. Scheibe sued
ProSupps under California consumer protection laws for
mislabeling the supplement. He alleges that he tested the
supplement using the FDA’s testing methods, but not that he
used the FDA’s sampling process. Based on the results of
these tests, he claims that the supplement is mislabeled.
The district court dismissed Scheibe’s complaint,
holding that the Act preempted his claims because he did not
plead that he tested the supplement according to the FDA’s
sampling process. We reverse because, even without these
sampling allegations, Scheibe’s complaint still allows a
court to draw a reasonable inference that ProSupps
misbranded the supplement under the Act. Scheibe has not
pleaded his state-law claims into preemption.
I. Scheibe alleges that the supplement is mislabeled.
On a motion to dismiss, we accept the allegations of the
complaint as true. See Ashcroft v. Iqbal, 556 U.S. 662, 678
(2009). ProSupps Hydro BCAA powder is a dietary
supplement containing an amino-acid blend. Consumers use
the supplement to increase the efficiency of workouts,
increase muscle mass, support weight loss, and aid in muscle
repair. According to the label, although a serving of the
supplement contains 10 grams of amino acids, it has zero
grams of carbohydrates and zero calories. Scheibe counts his
carbohydrates and calories to meet his weight-loss and
muscle-building goals. In August 2022, after reviewing the
supplement’s label, Scheibe bought the supplement in the
watermelon flavor.
6 SCHEIBE V. PROSUPPS USA, LLC
Scheibe appears to take his food labels seriously. He
asked an independent laboratory to verify the supplement’s
claim of zero carbohydrates and calories. The laboratory
tested a single 100-gram sample of the supplement using
FDA-approved testing methods. Nutrition labeling of dietary
supplements, 21 C.F.R. § 101.36(b)(2)(i) (2024)
(incorporating Nutrition labeling of food, 21
C.F.R.§ 101.9(c)(1)(i), (c)(6) (2024)); id. § 101.36(f)(1)
(incorporating id. § 101.9(g)(2)). The test found 41.2 grams
of carbohydrates in the sample, or 5.68 grams of
carbohydrates per serving. And it found 372 calories in the
sample, or 51 calories per serving.
Based on these test results, Scheibe claims that the
supplement’s label is false and so violates California law.
Scheibe filed a putative class action in federal district court
under the Class Action Fairness Act, 28 U.S.C. § 1332(d),
against ProSupps for: (1) violations of California’s
Consumer Legal Remedies Act, Cal. Civ. Code § 1750, et
seq.; (2) violations of California’s Unfair Competition Law,
Cal. Bus. & Prof. Code § 17200, et seq.; (3) violations of
California’s False Advertising Law, Cal. Bus. & Prof. Code
§ 17500, et seq.; and (4) unjust enrichment. ProSupps
moved to dismiss Scheibe’s amended complaint under
Federal Rule of Civil Procedure 12(b)(6), arguing that
Scheibe’s state-law claims are preempted because they hold
ProSupps to a different standard for carbohydrate and calorie
labeling than the Act. See 21 U.S.C. § 343-1(a)(4). The
district court agreed and dismissed Scheibe’s complaint.
In its order, the district court noted a divide between
district courts in the Ninth Circuit. Some courts hold that to
avoid preemption of state-law mislabeling claim, plaintiffs
must plead that they followed the FDA’s testing methods
and sampling processes. See, e.g., Salazar v. Honest Tea,
SCHEIBE V. PROSUPPS USA, LLC 7
Inc., 74 F. Supp. 3d 1304, 1313 (E.D. Cal. 2014). Other
courts hold that plaintiffs need only allege facts that allow a
court reasonably to infer that a product would be misbranded
if it were tested using the FDA’s testing methods and
sampling processes. See, e.g., Murphy v. Olly Pub. Benefit
Corp., 651 F. Supp. 3d 1111, 1124 (N.D. Cal. 2023).
We have jurisdiction under the Class Action Fairness
Act, 28 U.S.C. § 1332(d), and review de novo the grant of a
Rule 12(b)(6) motion to dismiss for failure to state a claim,
Bain v. Cal. Tchrs. Ass’n, 891 F.3d 1206, 1211 (9th Cir.
2018).
II. Scheibe did not plead his claims into preemption
under the Act.
To promote “[n]ational uniform nutrition labeling,” the
Food, Drug, and Cosmetic Act preempts state laws that
“directly or indirectly establish . . . any requirement for
nutrition labeling of food that is not identical” to the Act’s
nutrition labeling requirements. 21 U.S.C. § 343-1(a)(4).
Thus, “private plaintiffs may bring only actions to enforce
violations of ‘state laws imposing requirements identical to
those contained in the [Act].’” Kroessler v. CVS Health
Corp., 977 F.3d 803, 808 (9th Cir. 2020) (emphasis in
original) (quoting Farm Raised Salmon Cases, 175 P.3d
1170, 1177 (Cal. 2008)). So if a product’s label complies
with the Act, then the Act preempts any state-law claim that
the product is mislabeled. See Hollins v. Walmart Inc., 67
F.4th 1011, 1016 (9th Cir. 2023). And because compliance
with the Act can be determined only by the FDA’s testing
methods and sampling processes, the Act necessarily
preempts mislabeling claims proven only through testing
methods and sampling processes “not validated or accepted
by the FDA for use in th[at] context.” Id. at 1019.
8 SCHEIBE V. PROSUPPS USA, LLC
Because preemption is an affirmative defense ProSupps
bears the burden of showing that Scheibe’s claims are
preempted. See Durnford v. MusclePharm Corp., 907 F.3d
595, 603 n.8 (9th Cir. 2018) (citing Lusnak v. Bank of Am.,
N.A., 883 F.3d 1185, 1194 n.6 (9th Cir. 2018)). Under Rule
12(b)(6), “[o]nly when the plaintiff pleads itself out of
court,” by admitting all the elements of an affirmative
defense, may a complaint that otherwise states a claim be
dismissed. Id. (quoting Xechem, Inc. v. Bristol-Myers Squibb
Co., 372 F.3d 899, 901 (7th Cir. 2004)). To state a claim, a
pleading need only contain “a short and plain statement
. . . showing that the pleader is entitled to relief[.]” Fed. R.
Civ. P. 8(a)(2). This rule means that Scheibe’s complaint
merely has to nudge his claim “from conceivable to
plausible.” Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570
(2007). Thus, to state a “plausible” mislabeling claim that is
not preempted, Scheibe must plead facts that “allow[] the
court to draw the reasonable inference that the defendant is
liable.” Iqbal, 556 U.S. at 678.
Here, for ProSupps to be liable, Scheibe’s state-law
claims must survive federal preemption. In other words, the
complaint must allege that the supplement was mislabeled
“within the meaning of the federal regulations.” Nacarino v.
Kashi Co., 77 F.4th 1201, 1212 (9th Cir. 2023). This requires
Scheibe to plead facts that allow a court reasonably to infer
that the supplement is not only mislabeled under state law,
but also misbranded under the Act. To establish its
affirmative defense of preemption on a motion to dismiss,
ProSupps must show that Scheibe’s complaint fails to
support that inference.
To start, the Act requires labels on foods that list the total
amount of carbohydrates and calories contained in each
serving. 21 U.S.C. § 343(q)(1)(C)–(D); see also id. § 321(ff)
SCHEIBE V. PROSUPPS USA, LLC 9
(“a dietary supplement shall be deemed to be a food”).
Congress delegated authority, through the Secretary of
Health and Human Services, to the FDA to enforce the Act
through regulations. See 21 U.S.C. § 371(a); Hollins, 67
F.4th at 1014. Separate regulations control the nutrition
labeling of dietary supplements and foods, see 21 C.F.R.
§ 101.36; cf. id. § 101.9, but the regulations controlling
dietary supplement labels incorporate many of the
regulations controlling food labels. See, e.g., id.
§ 101.36(f)(1) (providing that “[c]ompliance with this
section will be determined in accordance with § 101.9(g)(1)
through (g)(8), (g)(10), and (g)(11),” with exceptions). The
FDA requires manufacturers to determine a nutritional
supplement’s content by testing a sample consisting of “a
composite of 12 subsamples (consumer packages) or 10
percent of the number of packages in the same inspection lot,
whichever is smaller, randomly selected to be representative
of the lot.” Id. § 101.36(f)(1). For carbohydrates, the FDA
requires testing each sample according to a method
prescribed by the Association of Official Analytical
Collaboration (“AOAC”) International. Id. (incorporating
id. § 101.9(g)(2)); id. § 101.36(b)(2)(i) (incorporating id.
§ 101.9(c)(6)). For calories, the FDA requires the use of any
of the six approved methods for testing each sample, one of
which is bomb calorimetry testing. Id. § 101.36(b)(2)(i)
(incorporating id. § 101.9(c)(1)(i)(E)).
ProSupps fails to show that Scheibe’s nutritional content
claims are preempted because Scheibe plausibly pleads that
the supplement is mislabeled in a way that also violates the
Act. Scheibe alleges that his testing methods complied with
FDA regulations: he used the AOAC method for
carbohydrates and bomb calorimetry for calories. But he
does not allege that he complied with the FDA’s sampling
10 SCHEIBE V. PROSUPPS USA, LLC
process. Instead, Scheibe simply alleges that one sample of
the supplement, tested by an independent laboratory,
contained more carbohydrates and calories than ProSupps
listed on the supplement’s label. Still, his preliminary testing
of that one sample is enough to avoid preemption on the
pleadings because it allows a court to draw a reasonable
inference that testing a composite sample according to FDA
regulations would show that the supplement is misbranded
under the Act. Scheibe’s single sample contained several
times more carbohydrates and calories than the FDA allows
to be listed as zero on the label. It is plausible that additional
samples would contain similar amounts of nutrients. And
even if those samples contained far fewer carbohydrates and
calories than Scheibe’s original sample, they still could lead
to a result that exceeds the margins for zero-carbohydrate or
zero-calorie labels and thereby establish misbranding under
the Act.
Maybe Scheibe’s first and only test result is an outlier.
Perhaps additional tests in discovery will confirm that the
supplement really does contain zero carbohydrates and zero
calories within the margins set by the FDA. But the Federal
Rules of Civil Procedure do not cast judges as skeptics of
pleadings. To the contrary, while “[f]actual allegations must
be enough to raise a right to relief above the speculative
level,” a court must “assum[e] that all the allegations in the
complaint are true (even if doubtful in fact)[.]” Twombly,
550 U.S. at 555. A plaintiff’s allegations need not defeat
every alternative explanation. Instead, “[p]laintiff’s
complaint may be dismissed only when defendant’s
plausible alternative explanation is so convincing that
plaintiff’s explanation is implausible.” Eclectic Props. E.,
LLC v. Marcus & Millichap Co., 751 F.3d 990, 996 (9th Cir.
2014) (emphasis in original) (quoting Starr v. Baca, 652
SCHEIBE V. PROSUPPS USA, LLC 11
F.3d 1202, 1216 (9th Cir. 2011)). ProSupps speculates that
“it may also be that this testing based on a single sample was
inaccurate” or that “the averaging across 12 samples could
provide results consistent with the labeling[.]” These
lingering possibilities do not make Scheibe’s mislabeling
allegations implausible. Because Scheibe’s test of a single
sample allows a court reasonably to infer that the supplement
would be misbranded if it were tested using the FDA’s
twelve-sample process, Scheibe’s state-law claims are not
preempted.
ProSupps fails to show otherwise. Beyond offering
speculative alternatives, it contends that, because Scheibe
tested only one sample, he admits that he did not comply
with the FDA’s sampling process. The FDA, ProSupps
argues, “does not require that every single product strictly
comply with the labeling regulations by having the exact
same amount of nutrients as stated in the supplement facts
panel.” But Scheibe does not argue that every serving of the
supplement must have the same amount of nutrients. Rather,
he argues that the amounts of carbohydrates and calories he
found in one sample of the supplement allows a court to
draw a reasonable inference that the FDA’s twelve-sample
process would find similar amounts. “Pleading that one has
conducted independent, non-FDA compliant testing that
suggests [misbranding] does not suggest that one could not
support allegations of [misbranding] with FDA-compliant
testing.” Murphy, 651 F. Supp. 3d at 1124 (emphasis in
original). To the contrary, the results of Scheibe’s single-
sample test suggest that he could support the complaint’s
allegations of misbranding under the Act and therefore avoid
preemption.
Further, we decline to adopt a rule that would, in effect,
require plaintiffs to perform the FDA’s sampling process at
12 SCHEIBE V. PROSUPPS USA, LLC
the pleading stage to avoid preemption. As Scheibe argues,
it may be impracticable for a plaintiff to test 12 different
samples “randomly selected to be representative of the lot”
before discovery opens. 21 C.F.R. § 101.36(f)(1). And the
fact that defendants may have exclusive control and
possession of critical facts—like their own product
inventory—cannot categorically prevent plaintiffs from
stating a plausible claim. See Soo Park v. Thompson, 851
F.3d 910, 928–29 (9th Cir. 2017). FDA preemption is no
exception to the rule that “plaintiffs are generally not
expected to provide evidence in support of their claims at the
pleading stage.” Durnford, 907 F.3d at 603 n.8. ProSupps
does not argue otherwise. Instead, it argues only that Scheibe
should have “alleged sufficient facts to support a plausible
inference that his laboratory testing demonstrates false
labeling if the FDA-mandated 12-sample methodology was
applied.” Yet this is what Scheibe has done.
We hold that a plaintiff’s failure to plead nutrition testing
according to the FDA’s sampling process does not preclude
a court from drawing a reasonable inference that a food’s
label violates the Act. Scheibe’s allegations that he tested the
supplement using FDA testing methods are sufficient to
avoid preemption, and we need not address whether they are
also necessary to do so. Because Scheibe alleged facts that
allow a reasonable inference that the supplement is
misbranded under the Act, his complaint survives
preemption on a motion to dismiss. ProSupps may establish
preemption if it later proves that the supplement’s labeling
complies with the Act. But at this stage of the case Scheibe
has stated a plausible claim that is not preempted.
REVERSED.
