Get Healthy Hair, Skin and Nails With BiotinHelpful in breaking down protein and carbohydrates in the body, biotin, or vitamin B7, can also keep hair, skin and nails healthy. Biotin also plays a key role in energy production, assists the body in the metabolism of fat into amino acids and is helpful in the production of hormones.
But if you don't get enough biotin in your daily diet from foods such as bananas, mushrooms, grapefruit, watermelon, peanuts, egg yolks or liver -- where the vitamin occurs naturally -- taking a biotin supplement can help fill in the gaps.
Biotin is a water-soluble vitamin, which means any excess of the vitamin within the body is excreted through the urine. Be sure to talk to your doctor before taking a supplement, especially if you are pregnant or of childbearing age.
