ZMA (Zinc, Magnesium, B6) is a well-established combination in sports nutrition. Athletes lose significant zinc and magnesium through sweat, and deficiency in either directly impacts testosterone production and sleep quality.
Our formula improves on traditional ZMA by using bisglycinate forms (not oxide) for both zinc and magnesium, dramatically improving absorption.

Customer reviews
- ★★★★☆Luke F.Verified buyer04/05/2026Night sweats and recovery improved
High-volume training was causing night sweats (cortisol dysregulation). ZMA has completely resolved this. Recovery is faster and I can train higher volume without accumulating fatigue. Classic stack for a reason.

- ★★★★☆Craig N.Verified buyer22/04/2026Take on empty stomach 30 mins before bed
Key to ZMA: must take on empty stomach (calcium blocks absorption) and 30-60 minutes before bed. Following this protocol the effects on sleep and testosterone are significant. Good quality, properly formulated.

- ★★★★★Steve P.Verified buyer17/11/2025Testosterone up, sleep deep
ZMA stack is the gym classic for a reason. Zinc + magnesium + B6 — all three are depleted by intense exercise. My free testosterone is measurably up (blood test confirmed), sleep is deeper, and morning energy is better. Don't overthink it, it works.
- ★★★★★James W.08/11/2025Libido and energy both improved
Mid-30s and noticed the classic testosterone-related decline. ZMA for 3 months and the difference is clear — energy, libido, strength. Blood test showed testosterone in upper-normal range for first time in years. Clean, properly dosed formula.
- ★★★★★Marcus D.Verified buyer22/09/2025Better sleep than any dedicated sleep supplement
Have tried magnesium alone, valerian, melatonin. This ZMA stack beats all of them for sleep depth. The zinc component is probably key — so many athletes are zinc-deficient. Wake up genuinely refreshed.
