Over the last few years, sports scientists have found an alarming rate of magnesium deficiency in people who engage in intense weight training. A recent study shows that low levels of this mineral might be seriously inhibiting your gains in the gym.
Information published in the journal Biological Trace Element Research describes how scientists measured the testosterone levels of athletes and sedentary people who were given supplemental magnesium. Both groups were given a daily dose of 10 milligrams of magnesium per kilogram of bodyweight. After four weeks, the two groups experienced a boost in free and total testosterone, although the athletes saw greater increases. Considering the relative low cost of magnesium supplements, and the plethora of health and performance benefits the mineral contributes, you can’t afford to skip this supplement.
