OstroVit MgZB is the brand’s classic magnesium–zinc–B6 stack in easy-to-swallow tablets — the ZMA-style night mineral athletes reach for when training depletes the basics. Official OstroVit positioning is simple and sharp: a high-quality dietary supplement combining three compounds for people who train hard and still want sleep, muscle function, and recovery locked into the daily log.
The enemy is random multi-tabs with token magnesium, oxide fillers that never land, and “night formulas” that hide the numbers. MgZB puts the three actives on one clinical card and times them where they belong — before bed. Brand copy frames it as a source of magnesium, zinc and vitamin B6 in a convenient tablet form with a full month of servings in one bottle.
Every 3-tablet serving delivers 375 mg magnesium (100% RI) from magnesium citrate, 15 mg zinc (150% RI) from zinc picolinate, and 2 mg vitamin B6 (143% RI) as pyridoxine hydrochloride. That is the current official nutrition table — full RI magnesium, over-RI zinc and B6, no mystery blends. Magnesium contributes to normal muscle function, electrolyte balance, reduction of tiredness and fatigue, and normal nervous-system and psychological function. Zinc contributes to normal protein synthesis, immune function, and the maintenance of normal testosterone levels in the blood. Vitamin B6 supports energy-yielding metabolism, nervous-system function, and the reduction of tiredness and fatigue — the authorised claim set OstroVit leads with on this SKU.
About 30 servings in the 90-tablet bottle (net weight 111 g) — a full month at one label serve per night. Vegan tablet formula, lab-tested batches on the brand site, zero caffeine, zero flavour dust. Heavy squat blocks, cut weeks, desk days that still need mineral cover — this is the lights-out stack you can actually stick to.
Take 1 serving (3 tablets) daily before sleep with water. Same time every night. No stims, no shake, no excuses.
