Comparing niacin (vitamin B3)

We count the vitamin B3 a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Niacin (vitamin B3) comes as niacin (nicotinic acid), niacinamide and inositol hexanicotinate (no-flush), 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 niacin (vitamin B3) with other ingredients are listed separately, because their price buys more than vitamin B3. 500 mg is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.
