Introduction

Biotin is one of the more recently discovered water-soluble B vitamins. Since 1942, it has been studied for its role in the production of many enzymes. Biotin is also known as the vitamin that produces healthy hair and helps prevent graying.

Biotin is found abundantly in many plant and animal foods. Bacteria in the intestines also produce a considerable amount of biotin. The best food sources include liver, milk, brewer’s yeast, bananas, grapefruit, watermelon, strawberries, and peanuts.

Reported Uses

Biotin plays a vital role in the production of energy from the metabolism of carbohydrates and fats. It also provides a number of benefits when used clinically. First, it may support the health of nails and offer treatment for brittle nails. (1) Meanwhile, it may help lower blood sugar levels in diabetics while possibly improving nervous disorders associated with diabetes. (2)

Biotin has a number of applications in children as well. In infants, one form of dermatitis has been associated with biotin deficiency. (3) , (4) Deficiency has also been associated with Sudden Infant Death Syndrome (SIDS).
