Biotin is a water-soluble vitamin that is part of the B-complex vitamins. It plays an important role in energy metabolism and cell growth. Biotin is found in small amounts in a variety of foods, but it can also be produced by intestinal bacteria.
Most people get enough biotin from their diet and products like shampoos. Your body will not absorb biotin when it is applied to the skin, which makes biotin injections preferable. When you have an injection with the correct dosage of biotin, it has been shown to increase hair growth and decrease hair loss. Hair thickness is improved, and your nails can also be strengthened.
What is biotin?
Biotin is a water-soluble vitamin that plays an important role in cell growth and energy metabolism. It is also known as vitamin B7, B8, or vitamin H. Your body cannot produce biotin directly, and it is not stored in the body for very long.
It is uncommon to be deficient, but excess consumption of raw egg (for example, in mayonnaise) can cause deficiencies. Avidin, a protein found in raw eggs, can bind to biotin and make it impossible for the body to absorb. Cooked eggs do not present the same problem.
