Associated risks/scrutiny: ZMA supplements are usually all-natural and there are no known negative side effects. "However, more than 350 mg of magnesium through supplementation can result in diarrhea," Broschart warns. If you are taking medication for your heart or to treat osteoporosis, you should consult your physician before supplementing with magnesium as there may be a drug/nutrient interaction. Vitamin B6 toxicity, can cause neurological effects, but this only occurs when amounts exceed 100 mg per day. Studies have found that zinc ingestion of about 60 mg per day through diet and supplementation can cause copper deficiency.
Testosterone makes you angry. This is probably the most common myth about T. The reality is that there’s no concrete evidence that high testosterone levels cause anger and violent outbursts. In fact, the opposite might be true; low testosterone, not high T, is what causes anger and irritability in men. As discussed above, having low T levels has been linked to depression in men and it just so happens that two of the primary symptoms of depression in men are increased angry outbursts and irritability. So if you’re chronically angry, you might be depressed, and you might be depressed because you have low T. As I mentioned above, I became less moody and irritable during my experiment, which I attribute to the boost in my testosterone levels.
