Beauty supplements are surging—biotin (or vitamin B complex), zinc, vitamins D and E for healthy hair and nails; vitamins A, C, E, collagen and probiotics for skin. If you are experiencing thinning hair, brittle nails or extreme skin dryness, you may be experiencing a deficiency of one of these nutrients. Supplements can help! And, be sure to eat enough protein (ideally 30 percent of your daily dietary intake) and healthy fats (olive oil, coconut oil).
