Vitamins and why we need them
Biotin RDA 300ug.
Biotin is necessary for cell growth, the production of fatty acids and the metabolism of fats, amino acids, proteins and carbohydrates. It plays a role in the citric acid cycle, which is the process by which biochemical energy is generated during aerobic (with air) respiration. Biotin is also helpful in maintaining a steady blood sugar level.
Biotin is used for the breakdown and utilisation by the body of food and serves as an essential coenzyme for four carboxylase enzymes, such as pyruvate carboxylase, each of which is important in metabolism. It promotes normal health of sweat glands, bone marrow, male testes, blood cells, nerve tissue, skin and hair.
Biotin supplements are sometimes given to help reduce blood sugar in diabetic patients. People with type 2 diabetes often have low levels of biotin. The major benefit of biotin as a dietary supplement is in strengthening hair and nails. Biotin supplements may improve thin or splitting toenails or fingernails and improve hair health.
Deficiency is rare as intestinal bacteria generally produce an excess of the body's daily requirement.Symptoms associated with biotin deficiency
