ZMA is a combination of zinc, magnesium and vitamin B-6 designed to maximize absorption and to 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.
