"Go for zinc: Zinc is the mineral that aids in the natural production of testosterone. Foods that contain a lot it: oysters, red meat (beef, pork, lamb), chicken, turkey and other fowl. Also, beans and dairy products contain zinc...
Onions and garlic contain Allicin, which also contributes to increased testosterone... Cabbage and other cruciferous vegetables (broccoli, bok choi, Brussels sprouts, cauliflower, kale, collard greens, radishes, kohlrabi and rutabagass), are testosterone boosters as well."
Watch out for hormones, pesticides and Antibiotics though, people!
