Where to Find It
Vitamin B6 deficiencies are thought to be very rare. Vitamin B6 deficiency can cause impaired immunity, skin lesions, and mental confusion. A marginal deficiency sometimes occurs in alcoholics, patients with kidney failure, and women using oral contraceptives. Some doctors believe that most diets do not provide optimal amounts of this vitamin. People with kidney failure have an increased risk of vitamin B6 deficiency.1 Vitamin B6 has also been reported to be deficient in some people with chronic fatigue syndrome.2
Best Form to Take
Vitamin B6 occurs naturally in three forms: pyridoxine, pyridoxal, and pyridoxamine. Pyridoxine and the phosphate ester of pyridoxal (pyridoxal 5’-phosphate, abbreviated PLP) are the most commonly used supplement forms of vitamin B6. Because nearly all studies showing a beneficial effect of vitamin B6 have used pyridoxine, it is generally preferred over PLP, even though PLP is the major biologically active form of vitamin B6. However, there may be some cases where PLP is more effective than pyridoxine, such as in cases of vitamin B6-responsive anemia, vitamin B6-dependent epilepsy, infantile spams, autism, and carpal tunnel syndrome.3
