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.

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.

Background reading
What the research says about these amounts
Not a score. Studies disagree with each other and change over time, so this sits beside the evidence rather than counting toward it — it is here so you can read the sources yourself.
The panel lists 5 mg of melatonin per serving. Studies we found used 0.5 mg–5 mg a day, so this sits inside that range.
0studied 0.5 mg–5 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
