NOW Foods ZMA combines zinc, magnesium, and vitamin B6 in a synergistic formula specifically designed to support athletic performance, recovery, and natural testosterone levels. Zinc and magnesium are two of the most commonly deficient minerals in athletes — both are lost through sweat during exercise and are critical for testosterone synthesis, muscle repair, protein synthesis, and quality sleep. Vitamin B6 enhances the absorption and utilization of both minerals. Clinical research on ZMA has shown improvements in strength, power output, and IGF-1 levels in college football players. Taken at bedtime without food, ZMA supports deeper, more restorative sleep alongside its performance-supporting benefits. NOW Foods provides pharmaceutical-grade zinc monomethionine/aspartate, magnesium aspartate, and pyridoxine in their GMP-certified facility with verified potency.
