Checked against public sources on August 7, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
The listing says 100 mg of l-theanine; the panel says 200 mg. We could not find an explanation for the difference — no blend, extract ratio, compound form or multi-capsule serving accounts for it. You are getting 200 mg of l-theanine per serving. …
“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.

We read 6 lines from the package photograph. It is our transcript of the label, not the manufacturer’s panel, and it may be incomplete.
The public sources did not settle the marketing promises on this label.
“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.
Published research exists for ingredients in this formula. Whether this product’s doses match those studies could not be confirmed.
Ingredient research can support context, but it is not a trial of this exact product.

Headlines first. Open evidence only when you want the source trail.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
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 findingThese are evidence gaps, not strikes against the product.
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.
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 120 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits below that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
Only the submitted seller page is identity-certain. Other destinations are shown as leads until a shared UPC/GTIN confirms the exact product.
