Coming from a nutritional supplement background and career most studies show men are zinc deficent. It is one of they most important minerals in terms of mens prostate and overall health.
I take around 80 mg of zinc daily in lozenge form.
Zinc is excellent for balancing testosterone and estrogen, prostate function and male menopause. It inhibts levels of aromatase, the testosterone-to-estrogen conversion enzyme. Which besides increasing your sex drive it helps slim you down as fat cells are full of aromatase and tend to store plentifull quanities of estrogen.
Its great for your sex life. That's why osyters get their reputation.
