Product info

From October until well into March, the sun hardly gets through — and your schedule mostly takes place indoors anyway. That is exactly where the vitamin D story begins.

Vitamin D is the vitamin your skin makes itself — but only when the sun is high enough. In the months with little sun, and with a life that mostly takes place indoors, that own production almost comes to a halt. That is exactly why D3 (cholecalciferol) is the fixed basis in almost every supplement routine.

D3 is fat-soluble: in this softgel the vitamin is dissolved in oil.

This is a product for anyone who spends a lot of time or works indoors, and for those who want one fixed daily dose of vitamin D: each softgel provides 100 µg vitamin D3 (4000 IU, 2000% RI). The softgel delivers the vitamin dissolved in oil — fat-soluble as intended, in one swallow. With 120 servings the pack lasts 120 days — months of supply.

One softgel a day, 120 days from one pot — with 120 servings you choose once and are set for months.

Form: vitamin D3 as cholecalciferol.

Per daily dose (1 softgel): Vitamin D3 (cholecalciferol) 100 µg (4000 IU) (2000% RI). Each nutrient named is well above the legal threshold of 15% of the reference intake.

This product is positioned as the fixed vitamin D basis: 100 µg D3 (4000 IU, 2000% RI) per softgel, dissolved in oil, one softgel a day, 120 days per pot, made in the EU with a certificate of analysis per batch.

Important to know: we may not adopt that positioning as a health claim. What we may say is listed above — these are the exact permitted wordings approved by the European Commission, and they apply to the nutrient named. A seller in the EU may not go beyond those wordings, however well known a use may be from experience, studies or reviews.

Why do you read so little about the effect of this product?

That is not down to us, but to European law. For food supplements we may only use health claims that have been officially approved by the EU.

The result? We can often tell you less than we would like to based on research, tradition and experience. That is how strict the rules are.

The full ingredient list is in the Composition tab.

Why do the softgels contain vitamin D3 and not D2?

This product contains vitamin D3 as cholecalciferol. In supplements, vitamin D is also used as D2 (ergocalciferol).

Both forms are permitted in food supplements in the EU. We make no statements about differences in effect.

Why take the D3 softgels with a meal containing fat?

The label advises: 1 softgel a day with water, with a meal containing fat. Vitamin D is a fat-soluble vitamin.

How many µg is 4000 IU of vitamin D3 in the D3 softgels?

IU (international unit) and µg are two ways of stating the same amount of vitamin D: 1 µg = 40 IU. One softgel contains 100 µg vitamin D3, which is 4000 IU.

Isn't 4000 IU of vitamin D3 per softgel too much?

The reference intake (RI) for vitamin D is 5 µg a day. One softgel provides 100 µg (4000 IU), which is 2000% RI.

EFSA has set a tolerable upper intake level (UL) for adults of 100 µg vitamin D a day, from all sources combined. Stick to 1 softgel a day.

What is the difference between these D3 softgels and D3 + K2?

This product contains only vitamin D3. If you want vitamin D3 and K2 in one product, a D3 + K2 supplement is an alternative.
