Vitamin A

What it does
Promotes good eyesight and has the same immunity-boosting properties as vitamin C.
Should you supplement?
Most guys get enough from food, and taking a pill could result in an overdose of A, which could lead to liver damage. But if you’ve been catching colds more frequently or if your eyesight seems weaker, try cod-liver oil—it’s what ancient mariners used to boost night vision.
Best food sources
Liver from chicken, beef, and pork, sweet potatoes, spinach, cantaloupes, carrots, kale, collard greens.
