Already naturally present in the body, biotin is a coenzyme that plays a key role in the metabolism of fatty acids, carbohydrates, and amino acids. It also contributes to the biosynthesis of vitamins B9 and B12 and plays a role in energy production. Biotin is found in most foods, albeit in small quantities (soy, egg, fish, legumes, oilseeds, brewer's yeast, etc...). In fact, it was first discovered during an experiment with raw egg white, which is rich in avidin, an anti-vitamin B8.
