The label promises 200 mg per serving. The panel says 200 mg. They match.

Natrol 5-HTP 200 mg Time Release
Checked against public sources between July 22 and July 24, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
FDA recall appears in this brand's history. An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
“Couldn’t verify” means we looked and found no public proof — not a mark against the product. Most supplement claims cannot be independently verified by anyone, so grey is the normal state of this industry.
What the Supplement Facts panel says

FDA recall appears in this brand's history
An exact-product recall is a direct signal. A different product from the same firm is company context, not a strike against this item.
Evidence and sources
This recall is not about the product on this page. Natrol, LLC recalled a different product on April 8, 2021. FDA has since closed that case. The recalled item was “Natrol Melatonin 3 mg, Tab 60 White bottle with purple flip-top cap.…”
Locked evidence record →Open the full source-linked findingRegistered owner records: NATROL, INC. · Natrol, Inc. · Natrol LLC
The public ownership record is ambiguous. We show the exact candidates instead of choosing one by name similarity.
Evidence and sources
USPTO returned multiple live supplement-class records for the exact brand wordmark: NATROL, INC., Natrol, Inc., Natrol LLC. These records answer who owns registrations for the brand; the separate product-to-owner or manufacturer link remains open.
Locked evidence record →Open the full source-linked findingListing claim matches the Supplement Facts panel
The label promise and the Supplement Facts amount agree.
Evidence and sources
The listing claims 200 mg; the photo-read Supplement Facts panel shows 5-HTP (5-Hydroxytryptophan) (from Griffonia simplicifolia) (seed) at 200 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.
Locked evidence record →Open the full source-linked findingEvery ingredient shows its amount · 2 ingredients listed.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
Evidence and sources
The panel gives a per-ingredient amount rather than hiding quantities inside a proprietary blend, so each one can be compared to published research.
Locked evidence record →Open the full source-linked findingThe barcode identity checks out · 047469074432.
The barcode matches, so we are checking the right product rather than a look-alike.
Evidence and sources
UPCitemdb resolves 047469074432 to "Natrol 5-HTP Time Release tablets Promotes a Calm Relaxed Mood Helps Maintain " (Natrol) — consistent with this listing.
