The conversion of niacin to tryptophan requires a coenzyme of vitamin B-6 called PLP, which is responsible for helping the enzyme kyneureninase to transport kyneurin into the niacin pathway. Without vitamin B-6, this PLP pathway can get diverted into another amino acid pathway, preventing the formation of niacin. Vitamin B-6 also works with iron and riboflavin during this conversion process. For your body to generate 1 milligram of niacin, you must consume 60 milligrams of tryptophan.
