How is zinc not number one, let alone not even on this list? Many men are deficient in it and it is what men's bodies are based on. Men are zinc based, women are copper based. It also controls over 3% of our gene expression and researchers have found "zinc fingers" which are areas of our DNA that require zinc to be able to "turn on" the genes.
Zinc also down regulates aromatase and is a very strong AI by itself. In fact German bodybuilders have taken 200 mg of zinc per day as their AI. Zinc is also key for many enzyme processes to work properly and especially key in production of Testosterone and digestion. Without zinc you cannot produce.
