Biotin: Role in the Body & Benefits

Role in the Body
Biotin is a member of the B vitamin family, although it is not considered a true vitamin in that it is made in our bodies by intestinal bacteria. It is necessary for the metabolism of carbohydrates, fats and proteins, and healthy skin, hair, and nails.

Dietary Sources
Most of our biotin is made by our intestinal bacteria, but it can be found in beef liver, brewer's yeast, cooked egg yolks, poultry, soybeans, saltwater fish, milk, cheese, rice bran and whole grains.

Who Is at Risk for Deficiency?
You may be at risk if you take long antibiotics for a long time, you are on a very low calorie diet for a long period of time, or bodybuilders who eat large quantities of raw eggs.

Benefits
There have been claims that biotin can prevent baldness, but the evidence is only in cases of an underlying biotin deficiency.

Cautions
Considered non-toxic.
