Regular intake of Biotin supports the production of keratin, a fundamental protein that strengthens hair and nails. This may result in more resilient hair and less brittle nails. Biotin contributes to healthier skin by aiding in the metabolism of fats, which are crucial for maintaining the skin's moisture barrier and overall complexion. Additionally, Biotin plays a key role in metabolising carbohydrates, fats, and proteins, processes that are essential for converting food into usable energy, thereby supporting the body’s overall energy levels.
