ZMA-5 is a new and improved formula that combines the original ZMA with the amino acid 5-Hydroxytryptophan (5-HTP) to create a synergistic and highly potent blend of ingredients. The components in ZMA are all important co-factors in the conversion of 5-HTP to serotonin, which is a neurotransmitter that helps to elevate mood and enhance sleep. This novel ZMA formula promotes an even deeper and more efficient sleep process while maximizing healing, tissue repair, anabolic hormone production, and muscle growth.
