Solaray and KAL Single B Vitamins!
B vitamins consist of eight water-soluble vitamins that play important roles in cellular metabolism. History past, the B vitamins were all once believed to be a single vitamin, referred to as vitamin B (much like how people refer to vitamin C or D). Later, research demonstrated that they are chemically distinct vitamins that often coexist in the same foods we eat. Vitamin supplements containing all eight are referred to as a vitamin B complex. Individual B vitamin supplements are referred to by their respective name of each vitamin (e.g. B1, B2, B3 etc.).
Several vitamin deficiency diseases can result from the lack of sufficient B-vitamins in the diet. Deficiencies of other B vitamins result in symptoms but by consuming proper amounts of B vitamins, one can successfully fight off deficiency diseases and live a symptom free healthy life.
