Fat in our food gets a lot of negative press. It’s hard to believe that fat represents anything besides unwelcome calories or a risk factor for heart disease.

Biotin is considered a B vitamin. It is a key co-factor in 5 enzymes that are part of the metabolic system that controls energy metabolism.
