Checked against public sources between July 20 and July 24, 2026 · LookCloser does not sell or recommend supplements.
Does the marketing hold up?
Magnesium: 500 mg on the label; adult upper limit 350 mg. This serving is about 1.4× the adult upper limit shown by NIH. The limit applies to SUPPLEMENTAL magnesium only (not from food).
“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 3 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.
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.
This serving is about 1.4× the adult upper limit shown by NIH. The limit applies to SUPPLEMENTAL magnesium only (not from food).
The panel lists 500 mg magnesium. NIH gives 350 mg as the adult Tolerable Upper Intake Level for SUPPLEMENTAL magnesium only (not from food). That is about 1.4 times the limit.
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.

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 500 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits above that range.
Study ranges differ between trials and change as research changes. This is background reading, not a pass, a failure, or a recommendation.
