This Organic Vitamin B Complex contains good levels of B vitamins (including Thiamin (B1) Riboflavin (B2) Niacin (B3) Pantothenic Acid (B5), Vitamin B6 and folate) that have been organically sourced from a blend of Guava, Mango and Citrus Lemon fruits extracts. These B Vitamins provide excellent support for those who lead strenuous lives. B-vitamins are involved with a range of normal body functions, from cellular growth to metabolism. The water solubility of B complex vitamins means that any excess is excreted and not stored. Therefore they must be continually replaced. All B vitamins, when mixed with saliva, are readily absorbed.
