Vitamin B6, also known as pyridoxine, is one of the hardest-working B vitamins – involved in more processes in the body than any of its siblings. It contributes to normal energy-yielding metabolism, the reduction of tiredness and fatigue, normal red blood cell formation, the regulation of hormonal activity, and the normal function of the nervous system and immune system.
B6 is water-soluble, so your body doesn't store it and needs a regular daily supply. The good news is that it's found in a wide range of everyday foods – fish, poultry, potatoes, peanuts and bananas among them – so most people get plenty from a balanced diet. One thing to know about B6 specifically: it's a nutrient where taking too much matters, so if you do supplement, sticking to recommended doses is important.
