pyridoxine is essential for the metabolism of proteins and haemoglobin ( the oxygen-carrying red pigment in your blood),and so the quantity that you need depends on how much protein you eat.
pyridoxine deficiency causes skin problems in and around the mouth and neurological problems but this rarely affects healthy people.
bacteria in your gut make pyridoxine some of which is absorbed through your intestinal wall. poultry fish pork eggs and offal are rich sources of pyridoxine as are oats peanuts and soybeans.
there is limited evidence that pyridoxine supplements may be helpful in relieving premenstrual symptoms.
high doses of pyridoxine over a period of time have been associated with nerve damage.
