Comparing vitamin D3

We count the cholecalciferol a label states per serving, whatever the pack size or the serving size, so every product sits on one scale. Vitamin D3 comes as vitamin D3 and vitamin D2, and each form has its own table, because someone buying one would not usually take another as a like-for-like substitute. A product with one other ingredient is ranked here with an “also contains” note; products that combine vitamin D3 with several others are listed separately, because their price buys more than cholecalciferol. 1,000 IU is our unit for comparing prices, not a dose to take: the label’s directions and a pharmacist decide that.

Newest prices checked: 29 October 2026; an older price shows its own date. Ranked purely by price per 1,000 IU — a comparison unit, not a recommendation. We earn commission when you buy through these links; it never affects the order.

2 of the 4 cheapest links on this page earn us nothing; the order is price alone. Shop by shop
