ZMA® is a unique, anabolic vitamin-mineral formula (patent-pending) manufactured by a proprietary process containing highly bioavailable forms of zinc and magnesium, including zinc l-monomethionine (L-OptiZinc®). Formulated with vitamin B-6 to further enhance zinc and magnesium absorption and utilization, ZMA® is a powerful non-steroidal, all-natural dietary supplement clinically proven to increase free testosterone, total testosterone and insulin-like growth factor (IGF-1) levels and enhance muscle strength in training athletes. ZMA® is the original zinc-magnesium supplement developed by SNAC Systems, Inc. and the only one validated by published research.

ZMA® was designed to optimize the absorption and availability of zinc and magnesium during peak times of muscle growth and repair. Both zinc l-monomethionine (L-OptiZinc®) and zinc/magnesium aspartate are unique and highly bioavailable forms of these minerals. The zinc l-monomethionine is absorbed in the front part of the small intestine at the mineral "receptor sites," while the zinc/magnesium aspartate is absorbed in the back of the small intestine via an "active transport" mechanism.

In addition, the zinc/magnesium aspartate in ZMA® consists of a unique complex of zinc, magnesium and aspartic acid, which enables the magnesium and zinc to reach the blood stream at the same time so that the desired synergistic effect can be obtained. (Note: Most zinc and magnesium aspartate products are not bound together in a single complex. Many contain insufficient amounts of aspartic acid necessary to fully react with the zinc and magnesium. Some are not reacted at all. These products contain high levels of unbound, poorly absorbed inorganic zinc and magnesium mineral salts, which are ineffective and may cause diarrhea or other undesirable effects.) The addition of vitamin B6 further increases the absorption and utilization of both zinc and magnesium.

ZMA® is the original zinc-magnesium supplement developed by SNAC System Inc. and the only one validated by published research. Unlike androstenedione (Andro), ZMA® is non-steroidal and won't cause undesirable side effects. ZMA® is destined to become the anabolic product of choice.

The recommended daily dose of ZMA® is three capsules (808 milligrams ZMA® per capsule) for men and two capsules for women taken on an empty stomach 30-60 minutes before bedtime. The reason for this is that healing, recovery, tissue repair and muscle growth are maximized during sleep.

Additional Recommendations

Since calcium interferes with the absorption of zinc and magnesium, it is recommended that ZMA® not be formulated with calcium-based excipients nor taken with dairy products or other calcium-containing foods or supplements. For additional information on dosing, follow manufacturer's recommended use printed on the label and/or talk to your healthcare professional.

ZMA® is a nutritional ingredient available in a wide variety of dietary supplements. Most products can be found at your local health food store; otherwise you can order directly from the manufacturer.  Click to search for finished products that contain ZMA®: Search for Products
