Twinlab ZMA Magnesium has the perfect blend of high quality Zinc and Magnesium to really take advantage of your body's own anabolic testosterone producing abilities. Specifically designed to raise endurance, enhance strength, recovery and growth, Twinlab ZMA is a smart choice. Working out can extensively drain you of zinc and magnesium. A zinc deficiency decreases muscle strength and endurance. Supplementing with it leads to Insulin-like growth factor, Growth Hormone, and Testosterone increases...not to mention increased muscle recovery. Magnesium deficiencies are just as bad, decreasing the oxygen available to your muscles. Supplementing with the correct amount (as in ZMA Magnesium) promotes endurance, muscle strength and relaxation.
