Guys zinc has many important functions in the our bodies , including as a micronutrient that is essential for the production of testosterone and other androgen hormones. If you are low on zinc, you will necessarily also be low on testosterone. By raising your zinc to a healthy level, you can support your body’s natural testosterone production. However, more zinc above and beyond the normal, healthy level will not have any additional effect on testosterone production. Zinc and selenium together increase function of androgen receptors. You don’t need to take a ton of it but make sure you levels aren’t low. More isn’t always better. Just some food for thought.
