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.

Confirmed evidence

What checked out00

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

Nothing could be independently confirmed from the available record.

Documented concerns

What needs caution00

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 missing04

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

Listing claim matches the label 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.

No data

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.

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 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.

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: 0.1 g of the 0.1 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

What is the product’s UPC or GTIN?

The barcode is how a product gets matched to outside records — certification registries, label databases, recall data. Without it, almost nothing can be cross-checked.

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

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.
