D-Biotin, also called Vitamin H, is a colorless, water-soluble member of the group of B-vitamins. Formerly it was known as vitamin H or coenzyme R. It has many benefits for the hair, skin, and nails.

Biotin is necessary for cell growth, the production of fatty acids, and the metabolism of fats and amino acids. It plays a role in the citric acid cycle, which is the process by which biochemical energy is generated during aerobic respiration. Biotin not only assists in various metabolic reactions but also helps to transfer carbon dioxide. As a consequence, it is found in many cosmetics and health products for the hair and skin, though it cannot be absorbed through the hair or skin itself.

1)Biotin(Vitamin H ) is the essential Nutrients of the retina,the Biotin deficiency could cause the Dry eyes, keratization, inflammation, even blindness.

2)Biotin(Vitamin H) can improve the body's immune response and resistance.

3)Biotin(Vitamin H) can maintain normal growth and development.

4)Biotin(Vitamin H) deficiency will cause reproductive functions recession, bad bone growth and  the obstruction of embryo and early childhood growth.

5) To help fat, glycogen and the synthesis and metabolism of amino acids in the human body is normal;

1.Hair problems: 

Biotin supplements are often recommended as a natural product to counteract the problem of hair loss in both children and adults. The signs and symptoms of biotin deficiency include hair loss which progresses in severity to include loss of eye lashes and eye brows in severely deficient subjects. Some shampoos are available that contain biotin, but it is doubtful whether they would have any useful effect, as biotin is not absorbed well through the skin.

2.Cradle Cap (Seborrheic Dermatitis):

 Children with a rare inherited metabolic disorder called phenylketonuria (PKU; in which one is unable to break down the amino acid phenylalanine) often develop skin conditions such as eczema and seborrheic dermatitis in areas of the body other than the scalp. The scaly skin changes that occur in people with PKU may be related to poor ability to use biotin. Increasing dietary biotin has been known to improve seborrheic dermatitis in these cases.

3.Diabetes:

 Diabetics may also benefit from biotin supplementation. In both -dependent and non--dependent diabetes, supplementation with biotin can improve blood sugar control.
