“GMP”
Evidence →“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.

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 findingCheckedCan you trust the review pattern?
Reviews rose from 9 to 33 between August 3, 2025 and June 11, 2026 — no sudden jump.
A count that moves steadily is ordinary. A sudden burst is what deserves a closer look.
Evidence and sources
Written reviews rose from 9 to 33 between August 3, 2025 and June 11, 2026. The largest rise inside any single 30-day window was about 7, so the count moved in steps rather than in one burst.

Research behind the findings
Dose and research context
We could not match an amount on this product to a studied range for the same ingredient, so these links are ingredient background rather than a measurement of this product.
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 300 mg of omega-3 (EPA + DHA) per serving. Studies we found used 300 mg–1.8 g a day, so this sits inside that range.
0studied 300 mg–1.8 g
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
The panel lists 100 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits below that range.
0studied 200 mg–420 mg
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
The panel lists 20 mg of melatonin per serving. Studies we found used 0.5 mg–5 mg a day, so this sits above 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.
The panel lists 10 mg of zinc per serving. Studies we found used 8 mg–40 mg a day, so this sits inside that range.
