USN ZMAG is a capsule supplement delivering zinc, magnesium and vitamin B6 in a 4‑capsule serving, marketed for recovery and sleep support.
+ Fully disclosed individual doses for each active. + Provides high levels of magnesium (500 mg) and zinc (20 mg) per serving. + Includes vitamin B6 (15.6 mg) which synergises with magnesium. + Positioned in the mid‑range price tier for its category.
- Zinc and magnesium compete for intestinal absorption when taken together. - High vitamin B6 may antagonise zinc absorption. - Gelatin capsule and potential crustacean, peanut and tree‑nut cross‑contamination may be unsuitable for vegans or those with allergies.
This product stands out by openly listing each mineral’s amount, a practice uncommon among peers, and by pairing magnesium with a notably high vitamin B6 dose that can boost nervous‑system support. However, the simultaneous high doses of zinc, magnesium and B6 raise modest absorption‑interaction concerns, and the gelatin capsule adds a non‑vegan element and allergen risk.
