The State of Supplement Claims · Category report
We ruled the 351 best-selling sleep listings on Amazon US, from 158 brands, against all 109 published standards. 76% fail. 34% of the brands carry at least one Critical finding. The category’s signature is the comparison to a drug: “non-habit forming” at 47 brands, “alternative to” a named prescription at 9, and “treats insomnia”, a named condition, at 14. 54 of the 158 brands carry a Critical claim, the class that can get a listing suppressed, on listings that were selling when we read them.

Executive summary
Three in four sleep listings fail.
267 of the 351 listings received a FAIL verdict, 76% against 76% across all eight categories. 7 listings, 2%, pass with nothing to fix. These are the bestsellers: melatonin, magnesium, valerian and the blends built around them.
The category’s favourite claim is a comparison to a drug.
“Non-habit forming” appears at 47 of 158 brands. It reads as reassurance; to a regulator it is a safety claim made by comparison to prescription sleep aids, and nothing on the listing substantiates it. “Alternative to” a named prescription, at 9 brands, is the same claim said louder, and it is Critical.
Where it turns Critical, it names the condition.
“Treats insomnia” at 14 brands and “treats anxiety” at 8 are named conditions. “No side effects” or “100% safe” at 22 is the most common Critical claim in the category, and at 15 brands a listing amount does not match the Supplement Facts panel.
Sleep copy is written in the shadow of the pharmacy: safer than the pill, no habit, no side effects, works on insomnia. Every one of those sentences borrows a drug’s claim, and a drug’s claim is what the machines that read listings are built to catch.
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 sleep listing by verdict · 351 listings
7 of 351 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 76% of the category’s bestsellers do not hold up.
Percentages rounded to the nearest point. Counts are exact.
Fail rate by category
Sleep sits mid-table on fail rate and near the average on the share of brands carrying a Critical finding. It is the largest category we scan after stress, so its numbers carry weight.
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 158 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 158 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. The sleep-specific rows are the comparison to a drug: “non-habit forming” (47 brands), “normalizes” or “restores” a sleep cycle (39), and the one Critical row in the top ten, “no side effects” or “100% safe” (22).
The claims that can end a listing
Every Critical finding in the category, grouped by the rule it breaks and counted by brand. Sleep’s Critical claims split three ways: a named condition, a false safety status, and a treatment verb.
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 351 listings we logged 1,719 findings. 113 are Critical, 7% of the category’s findings against 9% across the database, with 481 High findings behind them.

The dated record
The numbers above would matter less if enforcement were theoretical. It is not, and the insomnia and anxiety 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 sleep listing that says “treats insomnia” is not hiding from any of them.

Guidance
This is general information, not legal advice. The data does suggest a clear order of operations.
Drop the comparison to the pill.
“Non-habit forming” (47 brands) and “alternative to” a named prescription (9) are drug comparisons. Say what the product supports: “helps you fall asleep faster” and “supports restful sleep” are the allowed forms.
Insomnia is a condition. Occasional sleeplessness is not.
“Treats insomnia” is on 14 listings and “treats anxiety” on 8. “Occasional sleeplessness” and “a sense of calm” are the structure/function forms, and they sell.
Never promise safety.
“No side effects” and “100% safe” are Critical at 22 brands, the most common Critical claim in sleep. Delete the sentence.
Fix the paperwork.
The FDA disclaimer is missing at 88 brands, a Non-GMO claim has no document behind it at 82, “GMP certified” cannot be verified from the listing at 60, and at 15 brands a stated amount does not match the Supplement Facts panel.
