Vitamin B6 deficiency

Vitamin B6 is a nitrogen-containing compound that exists mainly in three natural forms: pyridoxine (PN), pyridoxal (PL), pyridoxamine (PM) and their phosphate derivatives (PLP, PNP, PMP). Vitamin B6 deficiency includes two kinds of vitamin B6 deficiency and vitamin B6 dependence in the narrow sense. The former refers to the syndrome caused by insufficient vitamin B6 intake from food or inactivation or increased excretion of vitamin B6 by taking a certain drug . Vitamin B6 dependence refers to the amount of vitamin B6 that a patient consumes in a healthy person, but still suffers from a deficiency of vitamin B6, which is mostly a genetic disorder.
