ZMA

ZMA (Zinc monomethionine aspartate and Magnesium Aspartate) is a supplement used by bodybuilders and athletes. It was developed by Victor Conte (founder of BALCO Laboratories in Burlingame, California) and is a blend of zinc, magnesium and vitamin B6. The formula is patented and the name "ZMA" trademarked by SNAC Systems Inc. It is used because research has suggested that it raises testosterone and IGF-1 levels which aids gains in muscle size and strength. Studies have also shown that ZMA increases the quality of sleep - helping the body repair itself after a hard exercise. Evidence also shows that ZMA tends to cause highly lurid and vivid dreams in some of the population.

A deficiency in zinc and magnesium is common in the general population. However, in athletes and very active people it is even more common due to these minerals being lost during exercise.

The proportion of ingredients generally used in products is 20-30 mg Zinc and 400-500 mg Magnesium.

ZMA use is not banned by any athletic organisations.
