Brewer's yeast is derived from a simple one-celled fungus. Typically produced while brewing beer, brewer's yeast can also be grown for use as a nutritional supplement. According to the University of Maryland Medical Center, brewer's yeast is a good source of selenium, chromium, protein and most B vitamins. Your body requires B vitamins to maintain healthy skin.
Benefits and Uses
In the book "The Essential Herb-Drug-Vitamin Interaction Guide," Dr. George T. Grossberg and Barry Fox advise that Commission E -- a German health agency -- approves brewer's yeast for treating acne, eczema and boils. In "Feed Your Skin, Starve Your Wrinkles," registered holistic nutritionist Allison Tannis states B vitamins in brewer's yeast provide necessary energy for your skin cells to replicate, while its high chromium content helps skin cells extract additional energy from fats, carbs and proteins.
