Biotin, an essential B-vitamin, plays a key role in renewing hair follicles to thicken and strengthen hair. It is a necessary component in cell growth at the follicle level, where hair is generated from rapidly dividing cells that become keratinized and turn into hair.
Biotin occurs naturally in many foods such as wheat germ, whole-grain cereals, whole wheat bread, eggs, dairy products, nuts, swiss chard, salmon, and chicken. However, the biotin in food is usually attached to protein and has relatively poor absorption. Therefore, taking a supplement may be more effective.
Aviva contains 5000 mcg of Biotin.
