Biotin is one of the B-complex vitamins. It aids in cell growth, the production of fatty acid, and the metabolism of carbohydrates, fats, and proteins. It also plays an important role in the utilization of the other B-complex vitamins.
In addition, the body requires sufficient quantities of this nutrient for healthy hair and skin. 100 mg of this nutrient daily has been shown to prevent hair loss in some men. It also promotes healthy sweat glands, nerve tissue, and bone marrow, as well as helping to relieve muscle pain.
A deficiency of this B vitamin in infants can lead to a condition called seborrheic dermatitis, or cradle cap, which is characterized by a dry, scaly scalp. In adults, deficiency of this nutrient is rare, as it can be produced in the intestines from foods such as those mentioned below. However, if a deficiency does occur, it can cause anemia, depression, hair loss, high blood sugar, inflammation or pallor of the skin and mucous membranes, insomnia, loss of appetite, muscular pain, nausea, and soreness of the tongue.
This B vitamin is found in brewer's yeast, cooked egg yolks, meat, milk, poultry, saltwater fish, soybeans, and whole grains.
