How Biotin Works

Benefits of Biotin

©2007 Publications International, Ltd. Biotin can strengthen fingernails, but its biggest impact may be in controlling diabetes.

Back in the 1940s, livestock researchers noticed that biotin made horse and pig hooves harder and stronger. More recently, this vitamin has been shown to strengthen nails in people whose nails are brittle. Daily supplementation of 2,500 mcg significantly increased nail thickness in about 90 percent of the patients.

Biotin is successful in treating cradle cap -- the dry or greasy scaly patches that form on the scalp of some infants. Although large studies have not been done on this use of biotin, infants' scalp conditions improved when their mothers were given extra biotin. Non-nursing infants benefited from direct supplementation.

Additional biotin does not seem to help seborrheic dermatitis, which is the same condition when it occurs in adults. Biotin's role in proper fatty acid metabolism may be responsible for its cradle-cap success.

Diabetics may also benefit from biotin supplementation. In both insulin-dependent and non-insulin-dependent diabetes, supplementation with biotin can improve blood sugar control and help lower fasting blood glucose levels, in some studies the reduction in fasting glucose exceeded 50 percent! Biotin can also play a role in preventing the neuropathy often associated with diabetes, reducing both the numbness and tingling associated with poor glucose control.

A typical dose for nursing mothers is 3,000 mcg twice a day. Non-nursing infants respond with 300 mcg per day. It's also a good idea to give non-nursing infants supplements of "friendly" bacteria such as Bifidobacterium bifidum to establish healthy intestinal flora that will produce biotin. People with diabetes have noticed good results at a dosage level of 8 milligrams (8,000 mcg) taken twice a day.

You probably didn't know you were getting more biotin than you needed already in your diet. But we hope this article enlightened the special-needs readers and help you get the proper dose.
