Comparing vitamin B6

We count the vitamin B6 a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Vitamin B6 comes as pyridoxine HCl and P-5-P (active form), and each form has its own table, because someone buying one would not usually take another as a like-for-like substitute. Products that combine vitamin B6 with other ingredients are listed separately, because their price buys more than vitamin B6. 50 mg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.
