Biotin, also known as Vitamin B7 or H, is a water-soluble vitamin that plays a significant role in the human body. It is involved in metabolism of carbohydrates, proteins and fats. Biotin is important for replication of genes. It promotes the growth of hair, skin and nails, as well as bone marrow and blood cells.
While biotin plays one of the leading parts in many essential functions in the body, it is not needed in big amounts. Real biotin deficiency is rather rare, as this vitamin is fairly bioavailable in foods, and exists in bacteria that live in human bowels. Averagely a person requires about 30 micrograms of biotin per day. The vitamin is sufficiently obtained from a well-balanced diet since it is found in lots of food sources including eggs and dairy products, meat and fish, fruits and vegetables, nuts and grains. Raw, fresh and unprocessed foods contain larger amount of biotin.
Because biotin is essential for healthy hair, its deficiency may cause slow hair growth and even hair loss. Therefore, many dermatologists and trichologists routinely recommend this vitamin as a natural hair loss treatment. Apart from its functions in general metabolism, biotin promotes new hair growth by increasing production of keratin, a fibrous protein which is key structural element of hair.
Biotin can be taken orally in the form of a dietary supplement. The vitamin is water-soluble and non-toxic. It is considered to be safe even when taken in large doses. Quiet often biotin supplements also contain zinc, magnesium, silica and other minerals and vitamins for natural hair growth. If you are not comfortable with oral medications you can still get the benefits of biotin through special shampoos and conditioners. These topical hair loss treatments can help you achieve the same results as with biotin supplements. However, some individuals are unable to absorb biotin through the scalp.
