Whey protein, creatine, beta-alanine — those are the shining stars of the supplement world, the ones that get all the attention and the positive press. Yes, it could be argued that their reputation is in direct proportion to their abilities to help build mass and strength, but there are other less-lauded supplements that nonetheless are mass-boosting powerhouses. Take, for example, the lowly minerals zinc and magnesium. The research on their ability to increase muscle strength and size is nothing short of extraordinary. And, conveniently, they come bundled together in a tidy little package called ZMA. But it’s not often that you see articles extolling ZMA’s benefits. That’s about to change.
