Testosterone is a hormone that is produced in large amounts by males (and a little bit in females), in the testes and adrenal glands. High testosterone levels are associated with sexual performance, reproductive function, muscle mass, hair growth, aggressive, competitive behaviors, and other such manly things. Testosterone levels tend to peak at the age of 40, and slowly decline from there. Luckily, there are many things you can do to increase testosterone, so if you feel like your T levels could use a boost, you've come to the right place.
An amazing mineral for masculine health, zinc is used to make testosterone, and also signals for the synthesis of testosterone. Many men don’t get enough. And if you get way too little zinc, you might end up developing man-boobs while experiencing ball shrinkage … making it easy to see why this is so important for test. Read some reviews and you’ll see me freaking out over how awesome zinc is for virility and testosterone. Look for a good form though, like Zinc Gluconate or Zinc Citrate — cheap forms of Zinc are not only less absorbable (and less effective), they tend to have more of its notorious side effects, like stomach upset or tasting metal in your mouth. Verdict: very positive.
