The three things most hard-training people are deficient in — in one capsule.
Zinc, Magnesium, and Vitamin B6 are depleted faster by exercise than almost any other nutrients. Sweat takes zinc and magnesium out directly. High training volumes increase demand for B6. Most people who train consistently are running low on all three — and don’t know it.
GYM HIGH ZMB delivers all three in their most bioavailable forms — aspartate-bonded zinc and magnesium for better absorption, with B6 at 750% NRV to support everything from hormone regulation to sleep quality. One capsule per day. 60 servings.

What’s in it and what each ingredient does
Magnesium Aspartate — 450 mg (120% NRV)
Magnesium is involved in over 300 enzymatic reactions in the body. For people who train, it’s critical for muscle function, reducing cramps, and supporting sleep quality. The aspartate form is better absorbed than cheaper oxide forms used in most supplements.
Zinc Aspartate — 30 mg (300% NRV)
Zinc supports normal testosterone levels, immune function, and protein synthesis. Athletes lose zinc through sweat — making supplementation particularly relevant for anyone training regularly. Again, aspartate form for superior bioavailability.
Vitamin B6 (Pyridoxine HCL) — 10.5 mg (750% NRV)
B6 supports normal hormone regulation, red blood cell formation, and the nervous system. It also plays a key role in protein metabolism — directly relevant if you’re eating high protein to support training. The 750% NRV dose is deliberate: B6 is water-soluble so excess is excreted, and the higher dose ensures meaningful support.
Works well for
People who train hard and regularly
Sweat depletes zinc and magnesium faster than most people realise. If you’re training 4+ days a week, your diet alone is unlikely to fully replace what you’re losing.
People who struggle with sleep quality
Magnesium deficiency is one of the most common causes of poor sleep and night cramps in active people. Taken before bed, ZMB supports relaxation and sleep quality.
Vegans and plant-based eaters
Zinc is harder to absorb from plant sources. If you eat mostly plants, supplementing with a well-absorbed form like zinc aspartate fills that gap directly.
People focused on hormone support
Zinc plays a direct role in maintaining normal testosterone levels. If you’re training to build muscle and want to support your natural hormonal environment, ZMB is a simple daily addition.
