B Vitamins are water-soluble and not stored in the body very effectively, therefore they need to be replenished daily. Insufficiencies may occur easily during times of dieting for weight loss, fasting or consuming the Standard American Diet (SAD), which usually includes too many processed/refined foods and excess sugar. Alcohol and drugs, including antibiotics, also deplete levels of B vitamins.
The B vitamins function as co-enzymes: they assist the enzymes, our biological catalysts, in implementing the tens of thousands of biochemical reactions and metabolic pathways that make life possible. Enzymes assist energy production, conversion of carbohydrates to glucose and the metabolism of fat and protein. B vitamins are also essential to optimal functioning of the central nervous system, and are used during physiological responses to stress and fatigue. Adequate levels of B vitamins are especially important for the formation of healthy hair and skin, and optimal functioning of the eyes and liver. The general muscle tone of the gastrointestinal tract is supported by the B vitamins, potentially promoting efficient bowel functioning.
The B vitamin group includes the following: B1 (thiamin), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B12 (cyanocobalamin), biotin, folic acid, choline, inositol and PABA (para-aminobenzoic acid). Orotic acid, pangamic acid, and B17 (laetrile) are intimately involved in many of the same pathways and are commonly regarded as quasi-B vitamins.
Biotin is an essential coenzyme for a variety of carboxylation reactions, and is involved in the metabolism of fats, sugars and amino acids. Biotin is crucial for the utilization of glucose for energy, the breakdown and utilization of fatty acids in energy production and the removal of the amine group in amino acid metabolism, thereby assisting amino acid synthesis into protein and the formation of DNA and RNA. As early as 1940, biotin was being researched for its effectiveness in promoting healthy hair and nails.
