ZMA is a testosterone-boosting combination of three essential nutrients: zinc, magnesium and vitamin B6. Zinc and magnesium play a role in over 500 metabolic reactions in the body. Vitamin B6 is very important for muscle protein synthesis.
ZMA is usually taken at bedtime and can support a significant increase in testosterone levels and strength as illustrated in the graph to the right. Athletes often use ZMA to enhance recovery from intense training.*
