Vitamin D3

Also called vitamin D, vit D, D3 and 2 more

cholecalciferol, colecalciferol.

The best price per 1,000 IU and per month, form by form, across 20 UK retailers, and where to buy it cheapest. A unit for comparing, not advice.

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. Products that combine vitamin D3 with other ingredients 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.

By shop

Each shop's vitamin D3 products, with where its cheapest sits in the market.

How we work out these prices

We count the amount of cholecalciferol stated on the label, converting between units (for example micrograms and IU) so every product is on the same scale.

Questions

Where can I buy vitamin D3 cheapest in the UK?

On 20 October 2026, the cheapest vitamin D3 per dose from a UK seller was High-Strength Vitamin D3 Tablets at WeightWorld (1p per 1,000 IU, 17p a month). Then Vitamin D3 4000iu - 365. 1 year supply. / Zip-Lock Eco Bag at ZipVit (1p per 1,000 IU, 17p a month) and Vitamin D3 + K2 (MK7) Tablets at WeightWorld (1p per 1,000 IU, 21p a month). That is by price per 1,000 IU, across 20 UK retailers and 207 products, with every price checked daily; the table above shows the working for each.

What is the best price per 1,000 IU of vitamin D3 today?

1p per 1,000 IU, for High-Strength Vitamin D3 Tablets at WeightWorld (1p per 1,000 IU, 17p a month), on 20 October 2026. The dearest of the 207 products we price is £1.13 per 1,000 IU, and the middle one is 8p.

How much does vitamin D3 cost per month?

At one 1,000 IU dose a day, the cheapest works out at 17p a month, for High-Strength Vitamin D3 Tablets at WeightWorld, on 20 October 2026. Across the 207 products we price it runs from 17p to £33.95 a month. A month is 30 days, and the figure follows the dose you enter in the table.

Which vitamin D3 form is cheapest per dose?

On 20 October 2026: vitamin D3 from 1p per 1,000 IU (WeightWorld) and vitamin D2 from 1p per 1,000 IU (Simply Supplements). The forms differ in what they contain, so this is a fact about price and not a recommendation of one over another.

Do bigger vitamin D3 packs cost less per dose?

Mostly, yes: on 20 October 2026, the 102 packs that last more than six months average 5p per 1,000 IU, against 27p for the 105 that last six months or less. The table marks the cheapest pack that lasts six months or less as the best value for anyone who would rather not buy a year at once.

How long does a pack of vitamin D3 last?

At one 1,000 IU dose a day, the packs we price last from 9 days to 5.9 years; the middle one lasts 6 months. Each row says how long its pack lasts at the dose you enter.

What does “per 1,000 IU” mean?

It is the unit we use to put every product on the same scale: the price of 1,000 IU of cholecalciferol, whatever the pack size or serving size. It is a comparison unit, not a recommendation of how much to take. Use the “Your daily dose” box to see costs at the amount you actually take.

Why are the vitamin d3 forms in separate tables?

We only rank products against others of the same form, because someone buying one form would not usually see another as a like-for-like substitute on price. Forms we compare separately: Vitamin D3; Vitamin D2.

Why is a product I have seen in the shops missing?

If a retailer’s listing does not let us confirm the amount per serving, the pack size or the form, we do not guess and we do not show the product. It appears once its label has been read and confirmed.

How up to date are the prices?

Prices on this page were last checked on 20 October 2026. Every table shows the date its prices were checked. Always confirm the price on the retailer’s site before buying.

Do retailers pay to appear higher?

No. We earn a commission when you buy through our links, but the order is set only by price per dose. No retailer or brand can pay for position.
