Pyridoxal-5'-Phosphate (Active B6) minerals The B vitamins arrive inVitamin B6 is not one molecule but six, and only one of them does any work. Pyridoxine the form in most supplements and most fortified food is a precursor. The liver must phosphorylate and oxidize it before it becomes pyridoxal 5' phosphate, the coenzyme that actually sits in the active site. That conversion depends on riboflavin, on zinc, and on functioning hepatic enzymes. When any of those falter, pyridoxine can accumulate while the active form
