Biotin is a vitamin. It is found in small amounts in many foods such as eggs, milk, or bananas.
Biotin is commonly used for hair loss, brittle nails, nerve damage, and many other conditions.
How does it work?
Biotin is an important component of enzymes in the body that break down certain substances like fats, carbohydrates, and others.
There isn’t a good laboratory test for detecting low biotin levels, so this condition is usually identified by its symptoms, which include thinning of the hair (frequently with loss of hair color) and red scaly rash around the eyes, nose, and mouth. Other symptoms include depression, tiredness, hallucinations, and tingling of the arms and legs. There is some evidence that diabetes could cause low biotin levels.
