Checked against public sources on July 26, 2026 · LookCloser does not sell or recommend supplements.

Does the marketing hold up?

Every ingredient shows its amount · 4 ingredients listed. Every ingredient shows its real amount — nothing is hidden in a proprietary blend.

“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.

The checks, one by one

The public sources did not settle the marketing promises on this label.

◐Partly confirmed2

“Cognitive Function: Formulated with Magtein (magnesium L-threonate) to help maintain healthy brain magnesium levels, promoting memory and learning…”

Ingredient evidence exists; on dose: label states 200 mg/serving — about 48% of the adult daily reference (adult RDA 310–420 mg elemental; NIH sets 350 mg/day as the supplemental upper level for elemental magnesium). A single serving isn’t meant to supply a full day, so this is context, not a shortfall. Caveat: chelate labels (glycinate, citrate) often state compound mass, which reads ~5–7× higher than elemental magnesium — the Supplement Facts panel settles which is meant.

“Magnesium 200 mg per serving”

The label promises 200 mg per serving. The panel says 144 mg. Because this panel was read from an image, confirm the physical label before treating the difference as settled.

Ingredient research can support context, but it is not a trial of this exact product.

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.

Public contextWill you get what you pay for?

Reaching a studied dose costs about $28/month

Comparing cost at a research-relevant amount shows how quickly the package is used and what the routine actually costs.

Evidence and sources

At 1.0 serving(s) a day to reach the low end of the studied range (200–420 mg), this product runs roughly $28 per month. A price observation, not a recommendation.

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 144 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.
