Vitamin B6, also called pyridoxine, is one of eight water-soluble B vitamins. Since these vitamins are soluble in water they are dispersed throughout the body dissolved in fluid. They are not stored in the body to any appreciable extent and must be replenished every day. Their influence on the body lasts for 14-18 hours after ingestion after which their potency decreases. An excessive intake of water-soluble vitamins is typically passed out through the urine. If the diet contains less than 50% RDA of water-soluble vitamins, symptoms from deficiencies may be displayed in as little as 4 weeks; much quicker than for fat-soluble vitamins.

All B vitamins, often referred to as B complex vitamins, assist and regulate carbohydrate, fat and protein metabolism. These are essential mechanisms which produce energy for the body. They also contribute to hemoglobin synthesis and red blood cell production which carries oxygen around the body. Furthermore, B complex vitamins help maintain muscle tone along the wall of the digestive tract and promote healthy skin, hair, eyes, mouth, liver and nervous system.

Vitamin B6 is important for the maintenance of the central nervous system and muscle cells. Furthermore, it aids in the removal of excess fluid of premenstrual women. It aids the production of DNA and RNA, the body's genetic material and assists the formation of antibodies in the immune system. It reduces muscle spasms, leg cramps, hand numbness, nausea and stiffness of hands, and promotes healthy skin. Vitamins B12, B6, and B9 (folic acid) work closely together to control blood levels of the amino acid homocysteine. Elevated levels of this substance appear to be linked to heart disease. Vitamin B6 is also essential for normal brain development and function, since it aids the process of making important brain chemicals called neurotransmitters. Vitamins B6 also helps the balance of sodium and phosphorous in the body.
