Vitamin B6 // Pyridoxine
Sources of Vitamin B6
Vitamin B6 must be obtained from the diet because humans cannot synthesize it.
Foods that are relatively rich in vitamin B6 include potato, spinach, banana, as well as chicken, turkey, and salmon.
Certain plant foods contain a unique form of vitamin B6 called ‘pyridoxine glucoside’, which appears to be only about half as bioavailable as vitamin B6 from other food sources or supplements. Vitamin B6 in a mixed diet has been found to be approximately 75% bioavailable (34).
People who follow a very restricted vegetarian diet might need to increase their vitamin B6 intake by eating foods fortified with vitamin B6 or by taking a supplement (40).
