Wheat germ is a concentrated source of several essential nutrients including Vitamin E, folate (folic acid), phosphorus, thiamin, zinc and magnesium, as well as essential fatty acids and fatty alcohols. It is a good source of fiber and protein. Wheat germ is a very good supplement for vegetarians or others who may struggle to get enough protein in their diets. Along with bran, germ is often a by-product of the milling that produces refined grain products. It can be added to protein shakes, casseroles, muffins, pancakes, cereals, yogurt, cookies, and other baked goods. It can go rancid if not properly stored in a fridge or freezer, and away from sunlight.
