The B vitamins are essential for producing energy in the body, are water soluble, and leave the body quickly. In this study, doctors found that when vitamin B2, or riboflavin, is low, levels of vitamin B6 are more likely to be low as well. In a group of 407 healthy adults, aged 18 to 92, 37 percent of those who were low in vitamin B6 were also low in riboflavin.
Discussing the findings, doctors said vitamin B6 depends on riboflavin, “which may be the limiting nutrient, particularly in older people, for maintaining adequate vitamin B6 status.”
