Vitamin B6 // Pyridoxine

Supply Situation

National nutrition surveys for some European countries have shown estimated mean dietary vitamin B6 (pyridoxine) intakes for adults of 3 mg/day, with a range of 1.6–3.6 mg/day (38).

In Austria, by contrast, certain population groups were shown to be deficient in vitamin B1 (thiamine), vitamin B2 (riboflavin) and vitamin B6 (pyridoxine). Women under the age of 25 and aged between 35 and 45 years did not meet requirements for B1, B2 and B6. Among Austrian men, only those aged 46–55 years met requirements for B2 and insufficient intake of B6 was demonstrated for those aged between 36 and 45 years and over 56 years (39).

An evaluation of vitamin B6 status in Indonesia children showed an inadequacy especially in those living in rural areas (49).

Surveys in the U.S. have shown that dietary intake of vitamin B6 averages about 2 mg/day for men and 1.5 mg/day for women.

A survey of elderly individuals found that men and women aged over 60 years consumed about 1.2 mg/day and 1.0 mg/day respectively. Both intakes are lower than the current RDA (1.7 mg/day for men and 1.5 mg/day for women).
