9. Vitamin E
Vitamin E is a critical antioxidant that protects your cells from free radicals, both inside and out. That’s why many skin products are fortified with the stuff. E also strengthens your immune system and may help slow macular degeneration if you have it. Find vitamin E in foods like peanuts, fruits, eggs, and leafy green veggies (sensing a pattern here).
If you want to get your RDA of vitamin E with a supplement, don’t take more than 33 IU of the synthetic stuff. Too much of it can increase the risk of bleeding in the brain. If you’re worried, remember that slathering it on your skin is also an option.
