“MANUFACTURING”
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.
“SUPPORT YOUR MUSCLES: Stay within your dietary limits while smashing sets at the”
Evidence →Ingredient evidence exists; on dose: label states 80 mg/serving — about 19% 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.

CheckedIs the label honest?
Listing claim matches the Supplement Facts panel
The label promise and the Supplement Facts amount agree.
Evidence and sources
The listing claims 80 mg; the photo-read Supplement Facts panel shows Magnesium at 80 mg per serving — the listing text and its photo-read panel agree; this is internal consistency, not independent testing.

Every ingredient shows its amount · 16 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.

Reaching a studied dose costs about $49/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 2.5 serving(s) a day to reach the low end of the studied range (200–420 mg), this product runs roughly $49 per month. A price observation, not a recommendation.

Reviews rose from 2 to 17 between December 12, 2025 and August 1, 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 2 to 17 between December 12, 2025 and August 1, 2026. The largest rise inside any single 30-day window was about 3, 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 80 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.
