Biotin

Biotin is an essential water-soluble B-vitamin that plays a key role in many functions throughout the body. It is important for the metabolism of proteins and carbohydrates, synthesis of hormones and cholesterol, and DNA replication. Biotin-dependent enzymes are involved in glucose metabolism, fatty acid synthesis, nervous system function, and skin and hair nutrition. Major food sources of biotin include milk, nuts, egg yolk, and wheat bran. In addition, probiotic microorganisms in the gastrointestinal tract can synthesize biotin. However, the amount of biotin synthesized is not sufficient to maintain normal biotin status, thus adequate amounts must be obtained from the diet or from dietary supplements. High potency amounts of biotin have been reported to favorably influence glucose metabolism in a variety of ways. Studies show that biotin supports glucose tolerance and insulin sensitivity and may also induce enzymes that inhibit release of glucose by the liver into the bloodstream. Added benefits of biotin on cholesterol and triglyceride metabolism have also been reported in some studies. In addition, Biotin promotes normal immunity and plays a critical role in skin health.
