“ABSORPTION MAGNESIUM GLYCINATE: Not every Magnesium form is readily absorbed by the body; Magnesium Glycinate is a form of Magnesium your body can…”
Evidence →Ingredient evidence exists; on dose: label states 240 mg/serving — about 57% 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.
Ingredient research can support context, but it is not a trial of this exact product.

Listing claim matches the Supplement Facts panel
The label promise and the Supplement Facts amount agree.
Evidence and sources
The listing claims 240 mg; the photo-read Supplement Facts panel shows Magnesium at 240 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.

Every ingredient shows its amount · 1 ingredients listed.
Every ingredient shows its real amount — nothing is hidden in a proprietary blend.
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.

The barcode identity checks out · 074312016776.
The barcode matches, so we are checking the right product rather than a look-alike.
Evidence and sources
Open Food Facts resolves 074312016776 to "Magnesium Glycinate" (Nature's Bounty) — consistent with this listing.

Reaching a studied dose costs about $7/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 $7 per month. A price observation, not a recommendation.

Reviews rose from 97 to 665 between August 5, 2025 and August 25, 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 97 to 665 between August 5, 2025 and August 25, 2026. The largest rise inside any single 30-day window was about 73, so the count moved in steps rather than in one burst.

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 240 mg of magnesium per serving. Studies we found used 200 mg–420 mg a day, so this sits inside 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.
