Health Tips: Functions of vitamins in human body

Vitamins promote normal growth, provide proper metabolism, ensure good health and protect against certain diseases. Vitamin is required by the body in small amounts for metabolism, to protect health, and for proper growth in children. Vitamins assist in the formation of hormones, blood cells, nervous-system chemicals, and genetic material. Vitamins mainly serve as catalysts for certain reactions in the body. They combine with proteins to create metabolically active enzymes that in turn produce hundreds of important chemical reactions throughout the body. The fundamentals of cells depend greatly upon vitamins. Vitamins are responsible for keeping cells strong, binding tissues, fighting infections, etc. Without vitamins our cells would not function properly and thus our organs would suffer and eventually we would no longer be able to survive. Vitamins help regulate metabolism, help convert fat and carbohydrates into energy, and assist in forming bone and tissue.

Vitamin A plays an important role in vision, bone growth, reproduction, cell division and differentiation. Vitamin B complex improves the body's resistance to stress. Aids in digestion, promotes good muscle tone, healthy skin. Vitamin B complex reduces muscle spasms, leg cramps, hand numbness and helps regulate blood pressure. Vitamin C is responsible for helping to build and maintain our tissues and strengthening our immune system. Adequate amounts of vitamin D is necessary for preventing bone loss. Vitamin E is the most effective, fat-soluble antioxidant known to occur in the human body. The main function of vitamin E is to maintain the integrity of the body's intracellular membrane by protecting its physical stability and providing a defense line against tissue damage caused by oxidation. Alpha-lipoic acid helps to neutralize the effects of free radicals on the body. Vitamin K plays an important role in blood clotting and bone metabolism (carboxylation of osteocalcin). Bioflavonoids have antioxidant, anti-inflammatory, antiallergenic, antiviral, and anti-carcinogenic properties.
