Sports Recovery* with Zinc, Magnesium Vitamin B-6 A Dietary Supplement ZMA is a synergistic combination of Zinc and Magnesium designed to maximize absorption and promote recovery from exercise. Zinc plays a central role in the regulation of cellular growth and tissue repair, as well as the maintenance of a healthy immune system. Magnesium is essential for the maintenance of electrolyte balance, energy production and normal neuromuscular function. Because physical activity can increase the need for these two minerals, ZMA is the ideal supplement to aid in their replenishment.*
