The State of Supplement Claims · Category report
We ruled the 183 best-selling energy listings on Amazon US, from 118 brands, against all 109 published standards. 68% fail. Only 28% of the brands carry a Critical finding, level with stress for the lowest share of the eight categories. What fails energy is proof language: “clinically proven” at 14 brands and a “clinical dose” nobody can verify at 13. Where it turns Critical, it promises no side effects. 33 of the 118 brands carry a Critical claim, the class that can get a listing suppressed, on listings that were selling when we read them.

Executive summary
Two in three energy listings fail.
125 of the 183 listings received a FAIL verdict, 68% against 76% across all eight categories. 4 listings, 2%, pass with nothing to fix. These are the bestsellers: B12, caffeine formulas, pre-workouts sold for energy, and the blends built around them.
It fails on proof, not on disease.
28% of energy brands carry a Critical finding, level with stress for the lowest share in the database. What fails the category is the language of evidence: “clinically proven” at 14 brands, a “clinical dose” with no study named at 13, “studies show” with nothing cited at 19, and “best” or “most effective” at 60, the most common finding in the category.
Where it turns Critical, it promises safety.
“No side effects” or “100% safe” at 12 brands is the category’s most common Critical claim, followed by “prevents” at 6. A stimulant sold as having no side effects is a claim no listing can substantiate for every user.
Energy copy sells proof it does not have: clinically proven, clinical dose, studies show, the best. The FTC reads each of those as a claim that needs evidence on the page, and none of these listings carry it.
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 energy listing by verdict · 183 listings
4 of 183 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 68% of the category’s bestsellers do not hold up.
Percentages rounded to the nearest point. Counts are exact.
Fail rate by category
Energy is seventh of eight on fail rate and last on the share of brands carrying a Critical finding. It is the category where the problem is proof language rather than disease claims.
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 118 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 118 ruled in the category, that carry the phrase or a direct variant. Bars are scaled to the top row.
Most of the ten are the paperwork and default-vocabulary failures found across the whole database, led here by the superlative: “best”, “most effective” or “strongest” at 60 brands. The energy-specific rows are proof claims: “clinically proven” (14) and a “clinical dose” that names no study (13).
The claims that can end a listing
Every Critical finding in the category, grouped by the rule it breaks and counted by brand. Energy’s Critical claims are few and they are safety promises and treatment verbs.
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 183 listings we logged 825 findings. 55 are Critical, 7% of the category’s findings against 9% across the database.

The dated record
The numbers above would matter less if enforcement were theoretical. It is not, and unsubstantiated proof claims are the FTC’s own territory.
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. An energy listing that says “clinically proven” with nothing cited is not hiding from any of them.

Guidance
This is general information, not legal advice. The data does suggest a clear order of operations.
Cite it or cut it.
“Clinically proven” (14 brands), “clinical dose” (13) and “studies show” (19) need the study, its dose and its population on the page. Without them they are unsubstantiated as written.
Retire the superlative.
“Best”, “most effective” and “strongest” are on 60 listings, the most common finding in the category. A comparison needs a comparator and evidence; a description does not.
Never promise safety.
“No side effects” and “100% safe” are Critical at 12 brands. Delete the sentence.
Fix the paperwork.
The FDA disclaimer is missing at 53 brands, a Non-GMO claim has no document behind it at 46, and “GMP certified” cannot be verified from the listing at 27.
