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.
The 100 mg 5-htp (5-hydroxytryptophan) claim matches the panel
We did the comparison: the listing claims 100 mg of 5-htp (5-hydroxytryptophan), and the listing-image panel shows 100 mg 5-htp (5-hydroxytryptophan) 1 tablet. Those amounts agree. This is internal consistency, not independent lab testing.
| Panel row | Amount | %DV | What to notice |
|---|---|---|---|
| Calcium | 32 mg | — | |
| 5-HTP (5-Hydroxytryptophan) | 100 mg | — |
FDA rules (21 CFR 101.36) require the amount of each dietary ingredient per serving unless hidden in a declared “proprietary blend” (legal, but a transparency yellow flag). A label stating no amount at all is non-compliant — a checkable red flag. This panel states amounts; any remaining comparison concerns the front-label framing.

Every check we ran
Listing claim matches the Supplement Facts panel
The listing claims 100 mg; the photo-read Supplement Facts panel shows 5-HTP (5-Hydroxytryptophan) at 100 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
FDA recall appears in this brand's history
Brand-level context only, not a finding about this product. Natrol, LLC recalled a different or not-exactly-bound product on 2021-04-08: “One lot of ALA 300 mg Cap-50 were labeled at Melatonin 3 mg Tab-60.” (status: Terminated). The recalled product was: “Natrol Melatonin 3 mg, Tab 60 White bottle with purple flip-top cap. Fall asleep faster, Stay asleep longer, 100$ Drug Free 1 Tablet 20 minutes before bedtime. Manufactured by N” — not necessarily the product on this page. Verify at FDA’s recall database.
180-day review-count history is on file
Exact-listing history records written-review counts from 361 on 2026-01-26 to 367 on 2026-07-15 (net +6). Count movements can reflect sales, listing variants, collection resets, or moderation; this history does not establish whether reviews are authentic.
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.
What the listing promises — claim by claim
Why is this shown?
| Claim | Status | What we found |
|---|---|---|
| Benefit claim “Natrol 5-HTP 100 mg Time Release, Helps Support a Balanced Mood, 90 Tablets One (1) 45 count…” | Not assessed We looked for: whether the ingredient doses on the label match the doses used in published research | Ingredient-level evidence for this formula isn’t in our knowledge base yet. Recorded as not assessed — not as a negative. |
“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
A brand storefront was found, but no exact-product price was published or identity-bound at build time.
Brand store natrol.com: 41 supplement products (+9 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.
