ZMA is a patented testosterone support formula developed by Victor Conte, it contains the minerals zinc and magnesium and the vitamin B6 in the precise levels needed to optimise testosterone levels in athletes. The zinc and magnesium are in bio available forms with the B6 being necessary for maximum absorption of the minerals.
Bodybuilders are continually looking forbodybuilding supplements to build muscle through increasing testosterone. In the 1970's, deficiencies in zinc and magnesium were found to prevent growth by reducing testosterone levels.
A quick look at the properties of zinc and magnesium will show why every weight trainer should be supplementing both. Zinc plays a crucial role in both protein synthesis and cell growth and formation. Zinc is a component in many enzymes involved in the metabolization of proteins, fats and carbohydrates. Testosterone levels fall without adequate zinc and the activity of insulin is impaired as is liver function. The immune system can be strengthened with adequate zinc and a deficiency can lengthen the time of colds, cause muscle wasting and lower appetite.
Magnesium deficiency is even more common than zinc, though deficiencies in both are very common in athletes. The reason for this is that more zinc is needed in times of growth and magnesium is an electrolyte so weight training increases the amounts needed above that can be easily obtained by diet alone. Magnesium is essential for bone strength, a strong immune system, muscle contractions and a healthy nervous system. Magnesium deficiency is a key cause of poor sleep and can also lead to insulin insensitivity.

Zinc and magnesium also have a significant role to play in antioxidant protection. Zinc and magnesium are structural components of antioxidants. Therefore ZMA will optimise antioxidant enzymes to reduce fatigue, muscle damage and exercise performance.
To get the benefits ZMA can offer, it is of great importance to take it when there is no calcium in the stomach (not with milk or whey protein). The best time is within an hour of your bedtime.
Multivitamins can contain identical amounts of these minerals but not cure the deficiency for athletes whereas the separate supplementation with ZMA products can. The reason for this is the theory of competing nutrients. Calcium is a known inhibitor of zinc and magnesium absorption (limiting their absorption by up to 70%). Therefore when calcium is present in the stomach, the body basically absorbs it and excretes the zinc and magnesium.
