Biotin, also known as vitamin H or vitamin B7, plays an important role in keeping skin, hair, and nails healthy, and supports the nervous system and liver. It is also a crucial vitamin during pregnancy to help the foetus develop optimally, and reduce the risk of premature birth or congenital disorders.
The word biotin is derived from the Greek word biotos, which loosely translates as ‘life and sustenance’; an accurate description of this vital vitamin.
Most people are able to manufacture enough biotin via the bacteria in their bowel to support their daily needs. Biotin is also present in small amounts in foods such as eggs, meat, seeds, nuts and avocados. However, pregnant women or people with certain medical conditions may be at risk of a deficiency that is hard to correct with oral supplements.
