Vitamin B7 (Biotin) Supplements

Biotin, also known as vitamin B7, helps your body convert food into energy and contributes to the maintenance of normal hair and skin – which is why it's such a well-known name in everyday wellness. It also contributes to normal macronutrient metabolism, the normal function of the nervous system, and normal psychological function.

Biotin is water-soluble, so your body doesn't store it and needs a regular daily supply. It's found in a wide range of everyday foods – cooked eggs, salmon, sardines, dairy, sweet potatoes, almonds, spinach and bananas among them – so deficiency is rare. For those who want the reassurance of a steady intake, biotin is available as a single supplement or as part of a B-complex.
