Single Vitamins

Frequently asked questions

What is the difference between a single vitamin and a multivitamin?

A single vitamin has one vitamin as its main ingredient, so its nutrition table is short. A multivitamin lists many vitamins and minerals and is found under Multi Vitamins. Some products here combine two vitamins, such as vitamin D3 with K2 or B12 with folic acid, and their labels state both amounts separately.

Why do vitamin labels use mg, µg and IU?

Each vitamin has its own usual unit: mg for vitamin C, vitamin E and most B vitamins, and µg (written mcg in many titles) for vitamins A, D, K, B12 and folate. IU, the international unit, is still printed on many labels for vitamins A, D and E. The conversion from IU to µg or mg differs for each vitamin, so rely on the amount and % NRV on the label.

Where do I find vitamin A, thiamin, riboflavin, niacin or vitamin B6?

Products for these vitamins are listed directly in Single Vitamins rather than in a subcategory. Titles name them as vitamin A or beta-carotene, vitamin B1 (thiamin), vitamin B2 (riboflavin), niacin or niacinamide, and P-5-P, short for pyridoxal-5-phosphate, a form of vitamin B6. Look for the vitamin's name in the product title.
