Worth knowing
Vitamin B6 is a group of related compounds (pyridoxine, pyridoxal, pyridoxamine), which the body converts into the active form — pyridoxal phosphate. It serves as a cofactor in more than a hundred enzymatic reactions, mainly related to amino acid metabolism.
The requirement for vitamin B6 is set in relation to the amount of protein consumed, since it is mainly used up in amino acid conversions. Some standard-setting bodies also differentiate reference values for older age groups — if your age group is broken out separately in the table above, you'll see this next to the specific value, along with an indication of the document it comes from.
