Vitamin B7 (Biotin)

Biotin or vitamin B7 is one of the essential B vitamins that your body needs for several functions. It plays a vital role in assisting enzymes (complex proteins that speed up biochemical reactions) to break down fats, carbohydrates and proteins in food. It also helps to regulate signals sent by cells and the activity of genes. Biotin helps the body convert carbohydrates into glucose which it can use to make energy. It aids in maintaining the mucous membranes of the skin. When people have a vitamin B7 deficiency, one of the signs is red, scaly rashes [DiBaise 2019]. Biotin also plays a crucial role in the process of metabolizing fat, which is essential for maintaining healthy skin. Your body cannot produce vitamin B7, so you have to get it from food or supplements.

It is one of the few vitamins that passes into cerebrospinal fluid. It may therefore have a role in improving memory and maintaining mental health [Kennedy 2016].
