Vitamin B7 Biotin


Biotin is a water-soluble B-vitamin that helps your body convert food into energy. It is especially important during pregnancy and breastfeeding. In addition, biotin is important for the health of your hair, skin and nails.

Biotin helps regulate your LDL (bad) cholesterol and blood sugar. Biotin is also necessary to produce keratin, a protein that promotes strong nails and hair.

Biotin is a water-soluble vitamin. That means it’s not stored in your body for long. Your body doesn’t naturally produce it, either. However, the bacteria in your gut can produce biotin. These bacteria, also called intestinal flora, have a healthy impact on your health.
