6. Vitamin A
Low levels of Vitamin A are linked to acne. Because Vitamin A can be toxic, don’t start supplementing your diet with pills before talking to your doctor.
Vitamin A deficiency can be serious. Taking it can improve eyes, fight yeast infections, prevent certain cancers, stop headaches and much more.
Add Vitamin A by eating liver (including cod), oily fish, and a whole host of cheeses (most of them stinky). If this sounds inedible, try eggs, sweet potatoes and winter squash.
