ZMA™ is a synergistic combination of zinc, magnesium and vitamin B6, specifically designed to enhance muscle strength, endurance, and recovery from exercise. Taken before bedtime, ZMA™ promotes deeper, more restful sleep, which is when maximum healing, and muscle growth takes place. ZMA™ consists of a unique covalently-bound complex of zinc, magnesium and aspartic acid, which enables the magnesium and zinc to reach the bloodstream at the same time so that the desired synergistic effect can be obtained.
ZMA™ Promotes Restful, Restorative Sleep
ZMA™ has been developed to improve sleep efficiency. ZMA™ is reported to effectively enhance sleep and is recommended to be taken 30-60 minutes before bedtime. Healing, anabolic hormone production and muscle growth are maximized during sleep, so quality sleep is extremely important to all of us.
Clinically Proven Effectiveness for Strength Training
ZMA™ has been used by dozens of world-class Olympic and professional athletes and bodybuilders, including members of the Super Bowl Champion Denver Broncos and Miami Dolphins football teams. It is also the only non-steroidal, all-natural zinc and magnesium supplement clinically-proven to increase insulin-like growth factor (IGF-1) and strength training in athletes. In a recent double-blind, placebo-controlled study conducted with NCAA college football players, researchers at Western Washington University found that eight weeks of nightly supplementation with ZMA™:
- Increased plasma zinc levels 29.1%, while placebo levels decreased 4.4% (a 33.5% difference)
- Increased plasma magnesium levels 6.2%, while placebo levels decreased 9.2% (a 15.4% difference)
- Increased total testosterone levels 32.4%, while placebo levels decreased 10.5% (a 42.9% difference)
- Increased free testosterone levels 33.5%, while placebo levels decreased 10.2% (a 43.7% difference)
- Increased IGF-1 levels 3.6%, while placebo levels decreased 21.5% (a 25.1% difference)
- Increased muscle strength 11.6%, while placebo strength increased only 4.6% (a 2.5-fold difference)
Zinc for Cellular Growth and Tissue Health
Zinc is an anabolic mineral required for the production of growth hormone and testosterone, which promote healing and growth. In addition, zinc helps improve energy by minimizing the build-up of lactic acid in muscle tissue. Zinc is also necessary for the maintenance of a healthy immune system.
Magnesium for Energy Production and Neuromuscular Function
Magnesium aids in the transport of oxygen to muscle tissue, which promotes strength, endurance and relaxation. Magnesium also activates enzymes necessary for the metabolism of carbohydrates and amino acids.
ZMA™ for Low Energy and Muscle Health
Unfortunately, zinc and magnesium deficiencies are common, and physical activity can increase the need for these important minerals. Numerous studies show that exercise and stress result in significant losses of zinc and magnesium. According to USDA researchers, when exercise-enhanced mineral losses are coupled with inadequate dietary intakes, athletes are at special risk to mineral deficiencies.
ZMA™ was designed to optimize the absorption and availability of zinc and magnesium during peak times of muscle growth. Both the zinc l-monomethionine and zinc/magnesium aspartate in ZMA™ 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 covalently-bound complex of zinc, magnesium and aspartic acid, which enables the magnesium and zinc to reach the bloodstream at the same time so that the desired synergistic effect can be obtained. The addition of vitamin B6 further increases the absorption and utilization of both zinc and magnesium.
ZMA™ for Healthy IGF-1 Levels
Insulin-like growth factor (IGF-1) is an anabolic hormone that decreases as we age. Growth hormones are essential substances produced in the body that help maintain muscle tissue, and support proper body function. Most growth hormones are secreted during the deep sleep cycle. It is then ncecessary reach this restorative sleep phase for good health. ZMA™ naturally promotes the deep sleep cycle, where healthy levels of IGF-1 are produced.
