The State of Supplement Claims · Category report
We ruled the 402 best-selling stress listings on Amazon US, from 235 brands, against all 109 published standards. 82% fail, the highest rate of the eight categories we scan, and only 3 listings pass with nothing to fix. The category fails on the vocabulary of correction: “balances hormones” at 101 brands, “normalizes” and “restores” at 56. Where it turns Critical, it promises safety: “no side effects” or “100% safe” at 27 brands. 65 of the 235 brands carry a Critical claim, the class that can get a listing suppressed, on listings that were selling when we read them.

Executive summary
Stress fails more than any category we scan.
329 of the 402 listings received a FAIL verdict, 82% against 76% across all eight categories. 3 listings, 1%, pass with nothing to fix. These are the bestsellers: ashwagandha, adaptogen blends, cortisol formulas, magnesium and mood stacks.
It fails on High findings, not on disease claims.
28% of stress brands carry a Critical finding, below the 42% average. What fails the category is volume: 857 High findings, led by “balances hormones” at 101 brands, “normalizes” or “restores” at 56 and “boosts immunity” at 44. Each describes a return from a disordered state, which is treatment language.
Where it turns Critical, it promises safety and relief.
The most common Critical claim in stress is not a disease name. It is a safety promise: “no side effects” or “100% safe” at 27 brands. Next come “treats anxiety” and “for anxiety” at 15, and a product name that implies treatment at 12: a claim printed on the label, the listing and every ad at once.
Stress copy sells correction: balance the hormones, normalize the cortisol, restore the calm. A regulator reads each of those as treating a disorder, and a listing that adds “no side effects” has made a drug claim and a safety claim in four words.
Method and data
Listings enter the database through the same engine that runs our paid audits. Each listing is ruled, phrase by phrase, against all 109 standards in force at the scan, built on FDA structure/function rules, FTC substantiation guidance and Amazon’s supplement claims policy. Every finding must quote the page word for word, and any quote the software cannot find on the page is discarded before it enters published figures. Since 28 Sep 2026 the category also holds every ruled listing from Amazon’s own Best Sellers lists for it. Paid audit verdicts are signed by a licensed pharmacist. Individual brands are never named in public data. The full method and the standards behind it are documented on the Standards page.
The whole-database figures this report is drawn against are in The State of Supplement Claims; the category’s screenshot-ready numbers are on its scorecard.
The verdict split
A FAIL verdict means the listing carries at least one Critical or High finding, a phrase that breaks a published standard seriously enough that the listing as a whole does not pass. FIX THEN PASS means the only findings were Medium or Low. PASS means no findings at all.
Every ruled stress listing by verdict · 402 listings
3 of 402 listings pass with nothing to fix. A FAIL verdict does not mean the product is unsafe or ineffective; this report measures marketing language, not chemistry. But marketing language is what regulators, platforms and courts read, and by that measure 82% of the category’s bestsellers do not hold up.
Percentages rounded to the nearest point. Counts are exact.
Fail rate by category
Stress is first on fail rate and below the average on the share of brands carrying a Critical finding. The two measures answer different questions: how often a listing has something serious to fix, and how often a brand has written a claim that can draw enforcement on its own. Stress is the category where nearly every listing has something serious to fix.
The right-hand column is the share of that category’s brands carrying at least one Critical finding. Rows count every listing ruled in that category; a listing sold into two categories is ruled in each.
Fail means at least one Critical or High finding on the live listing.
The phrase table
Ranked by how many of the 235 brands carry each one. Struck phrases are quoted from live listings. The brands are not named. Their copy names them.
Counts are distinct brands, among the 235 ruled in the category, that carry the phrase or a direct variant. Bars are scaled to the top row.
Six of the ten are the paperwork and default-vocabulary failures found across the whole database: a missing disclaimer, an undocumented Non-GMO claim, an unverifiable GMP badge, a superlative, an ingredient weight with no serving size, an uncited “studies show”. The stress-specific rows are the vocabulary of correction. “Balances hormones” (101 brands) and “normalizes” or “restores” (56) describe a return from a disordered state. “All-natural” (42) is a safety implication with no definition behind it. And “boosts immunity” (44) has drifted in from another category’s copy, where it fails just the same.
What passes
The same benefits, said the way the passing best sellers say them. Each phrasing below sits on the best-selling listings of at least three brands, on a line with no Critical or High finding, and no finding in the category quotes it. Each one carries the benefit a shopper is looking for without the wording a platform’s review can flag.
Counts are distinct brands, among the 235 ruled in the category, that use the phrasing on a line with no Critical or High finding. Phrasings that differ only in “your”, “the” or the form of the verb are counted together. A phrasing that passes here can still fail beside a disease word, so the line around it matters too.
The same benefit, worded twice. The struck line is quoted from live listings in the category and breaks the standard linked beside it. The line above it carries the same benefit on passing listings, without the claim that can get a listing suppressed.
Say “supports calm” 17 brands, on passing lines
Not “cortisol calm hormonal balance” 54 brands · CV-ID-08 High
Say “help promote relaxation” 38 brands, on passing lines
Not “relax restore unwind” 30 brands · CV-ID-10 High
Say “support immune function” 5 brands, on passing lines
Not “boost immunity and health” 27 brands · CV-ID-07 High
Say “support a balanced mood” 6 brands, on passing lines
Not “supporting emotional balance and overall hormone health” 11 brands · CV-ID-08 High
Say “support mental clarity” 8 brands, on passing lines
Not “for energy clarity and hormonal balance” 6 brands · CV-ID-08 High
Say “support a balanced mood” 6 brands, on passing lines
Not “restore mood balance” 7 brands · CV-ID-10 High
Struck lines are lowercased and quoted without the brands that carry them. Passing means no finding against the 109 published standards; it is not a ruling on any one listing, which is read in context.
The claims that can end a listing
Every Critical finding in the category, grouped by the rule it breaks and counted by brand. Stress produces fewer Critical findings than gut, but a different kind: a false safety or regulatory status leads, then a treatment verb, then a named condition, anxiety above all.
Counts are distinct brands with at least one Critical finding of that class. A brand can appear in more than one row.
Inside the findings
Across the 402 listings we logged 2,295 findings. 128 are Critical, 6% of the category’s findings against 9% across the database. Stress fails on the weight of High findings: 857 of them, more than one in three of everything logged.

The dated record
The numbers above would matter less if enforcement were theoretical. It is not, and the anxiety and mood claims that define this category are the ones it has reached most recently.
Four institutions with four different incentives read supplement listings the same way, and the platforms read with machines that keep getting better: Amazon’s AI scans billions of listing changes a day, and Google’s Gemini models read what an ad means. A stress listing that says “treats anxiety” is not hiding from any of them.

Guidance
This is general information, not legal advice. The data does suggest a clear order of operations.
Retire “balances hormones” and “balances cortisol”.
At 101 of 235 brands, it is the category’s most common High claim after the missing disclaimer. “Balance” implies correcting a disordered state. The strongest wording the rules allow talks about healthy levels already within the normal range, and about helping the body adapt to occasional stress.
Never promise safety.
“No side effects” and “100% safe” are Critical at 27 brands. No listing can substantiate an absolute safety claim for every user, and the sentence adds nothing a shopper needs. Delete it.
Anxiety is a condition. Occasional stress is not.
“Treats anxiety”, “for anxiety” and their cousins (panic, depression, ADHD) are disease claims, at 15 brands. “Occasional stress”, “a sense of calm” and “helps the body adapt” are the structure/function forms and they sell.
Check the product name before the copy.
A name that implies treatment is a claim on the label, the listing and every ad at once, at 12 brands here. It is the most expensive finding to fix after launch and the cheapest before it.
Fix the paperwork.
The FDA disclaimer is missing at 123 brands, a Non-GMO claim has no document behind it at 129, “GMP certified” cannot be verified from the listing at 89, and at 12 brands a stated amount does not match the Supplement Facts panel, which Amazon’s policy treats as a listing error on its own.
