For more information on Biotin, please use the search box above. Biotin is a B-vitamin which we should get from our diet, though it is also produced by intestinal bacteria. It has to be supplemented in patients receiving intravenous feeding. Supplementation is also necessary for people eating a lot of raw egg white.
Some biotin is available in a wide range of foods, though amounts are always very small.
Alas, the biotin needed for normal functioning of the human body is considered just around 200 micro grams per day. Biotin deficiency is rare, except for people on an intravenous feeder if biotin is not supplemented, and except for those eating a lot of raw eggs, including egg whites. Raw egg white contains the avidin molecule which binds to biotin in the stomach, thus making it unavailable for absorption through the intestine. Cooking eggs destroys avidin. Biotin is needed by the body to maintain hair growth and hair color.
