How to read this report

What this is. We compare what a listing claims against what public records show — label arithmetic, barcode registries, NIH’s label catalog, FDA enforcement data, certification registries, and published research. Every statement below traces to one of those.

What the states mean. Confirmed = an outside source agrees. Contradicted = an outside source disagrees. Caution = something needs explaining. No data = we looked and found nothing — a gap, not a strike.

What it is not. A clean record is not an endorsement and never proof a product works. A thin record is not an accusation. We publish evidence and gaps; the conclusion is yours. Nothing here is medical advice.

Something wrong? Every figure is meant to be checkable — sources are named and linked. Send a correction and we’ll fix the record.

Panel, decoded

The 200 mg 5-htp (5-hydroxytryptophan) claim matches the panel

MARKETING200 mg — listing title
PANEL5-HTP (5-hydroxytryptophan) 200 mg — same amount5-HTP (5-hydroxytryptophan) 200 mg
matches panel

We did the comparison: the listing claims 200 mg of 5-htp (5-hydroxytryptophan), and the listing-image panel shows 200 mg 5-htp (5-hydroxytryptophan) 1 capsule. Those amounts agree. This is internal consistency, not independent lab testing.

Every check we ran

Confirmed evidence

What checked out4

These checks found support in the public record. They confirm specific facts, not the product as a whole.

Testing claim names a recognized certifier

A named certifier/laboratory appears in the listing (registry cross-check pending).

Confirmed

Every ingredient amount is disclosed

The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.

Confirmed

Exact trademark owner identified

USPTO lists eSupplements, LLC (LIMITED LIABILITY COMPANY) in UTAH, USA for the exact brand wordmark. This identifies the USPTO mark owner or applicant; it does not by itself prove who manufactures or sells this product.

Confirmed

Barcode confirmed in an outside database

Open Food Facts resolves 810014675145 to "5-HTP" (Nutricost) — consistent with this listing.

Confirmed

Documented concerns

What needs caution0

These are documented contradictions or claims that need more evidence. They are separate from missing data.

No contradictions or product-specific cautions were found at this check depth.

Unresolved public record

What is still missing5

We looked for these signals but could not settle them from public sources. A gap is not a strike.

The listing doesn't publish enough to check the math

The saved listing evidence does not establish net weight, per-serving dose, so the dose claim cannot yet be checked against serving arithmetic. This is a neutral evidence gap, not a pass or strike.

No data

Public label filing not saved

We have not found a public label filing for this exact product. That is a gap in our records, not evidence that no filing exists.

No data

This item belongs to a catalog variation family

The paid catalog links this exact item to a parent listing. Review counts on public product pages may be shared across sizes, flavors, or other variants, so the count history is listing context — not evidence that reviewers received or tested this exact variant.

No data

180-day review-count history is on file

Exact-listing history records written-review counts from 232 on 2025-07-25 to 313 on 2026-08-09 (net +81). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.

No data

Package and trademark records name different responsible entitie

The package says manufactured for: nutricost, 351 E 1750 N, Vineyard, UT 84059. USPTO names eSupplements, LLC as the exact wordmark owner. That can be a normal distributor, manufacturer, or licensing relationship; the saved records do not establish the relationship.

No data

What to ask and check

What would settle the open questions

Why is this shown?
Everything we couldn’t verify is something a person can still ask about. Rather than leave gaps sitting as dead ends, we turn each one into a specific question — the exact document, citation, or number that would settle it — plus the things you can confirm yourself with the bottle in your hand.

Ask the brand or seller

1

Answered by the panel: 0.2 g of the 0.2 g headline is 5-htp. Which independent lab can confirm that amount in this product?

The panel resolves the front-label arithmetic. The remaining question is lot-specific contents and stability; published category testing gives context, not a test of this product.

2

Can you send the certificate of analysis (COA) for the lot number on my bottle?

A real COA names the testing laboratory, the test date, the lot it covers, and what was measured. “Third-party tested” with no document behind it is a marketing sentence.

3

Is this label filed with NIH’s Dietary Supplement Label Database (DSLD)?

Filing is voluntary, so absence proves nothing — but a filed label puts the full ingredient table on public record where anyone can read it.

Most brands and sellers publish a contact route. A clear answer adds evidence to the record; no answer leaves the question open.

Check for yourself — no one’s permission needed

1

Compare the panel on the bottle in your hand to the one shown in this record.

Ours was read from listing photos and can contain reading errors. The physical label is the source of truth — if they disagree, tell us and we’ll correct the record.

2

Scan the barcode on the package and confirm it reads 810014675145.

A mismatch between the barcode on the box and the one on the listing is worth pausing over — it can indicate a different variant, a repack, or a counterfeit.

3

Check the lot number and expiry on the bottle against any COA you’re given.

A certificate that doesn’t name your lot doesn’t describe what you’re holding.

These are the open questions on this specific record — not a warning about the product, and not a suggestion to buy or avoid it. Getting them answered is how you decide for yourself.

What the listing promises — claim by claim

Why is this shown?
A listing’s promises are the reason people buy. Each one gets its own row: what was promised, what evidence would settle it, and what we could actually find. We never call a claim false — only whether proof proportionate to it exists on the public record.
ClaimStatusWhat we found
Quality-testing claim
“…120 Vegetarian Capsules of High Quality 5-HTP 200mg Per Vegetarian Capsule 3rd Party Tested by ISO-Accredited Laboratories Non-GMO, Gluten Free, Vegetarian Made in a NSF”
Partly supported
We looked for: the observed listing, saved brand product page, any linked COA or test report; NSF, IFOS, USP, Informed-Sport were not queried
A testing body is named on the listing, but we found no lot-specific certificate of analysis.
Manufacturing claim
“…120 Vegetarian Capsules of High Quality 5-HTP 200mg Per Vegetarian Capsule 3rd Party Tested by ISO-Accredited Laboratories Non-GMO, Gluten Free, Vegetarian Made in a NSF”
Partly supported
We looked for: the facility registration or certificate behind the claim
“GMP-certified” describes factory processes, not what is in the bottle. The claim does not name a certifier or public register that a shopper can check.

“No evidence located” does not mean a claim is false — it means the seller has not put evidence proportionate to the claim on the public record, and we could not find any. Absence of proof is not proof of absence.

Where it sells

We found a brand storefront, but we could not match any price on it to this exact product when we checked.

Brand store nutricost.com: 199 supplement products (+51 merch items) — for comparison, single-focus brands typically carry 5–30 products; very broad catalogs are common among companies that rebrand ready-made formulas — a pattern note, not a verdict.

Reference links for identification only — LookCloser has no affiliate relationships and earns nothing from any link on this page.

Ingredient science

No knowledge-base entry yet for this formula's active ingredients — entries are added as the KB grows. Absence of a science card is a coverage gap, not a judgment.
