Doctor's Best Vitamin D3 1000IU 180 Softgels is a food supplement providing 25 mcg (1000 IU) of vitamin D3 as cholecalciferol in each softgel. The softgel is made with extra virgin olive oil, and the 180 softgels last 180 days at the suggested one a day.

Key Features

• 25 mcg (1000 IU) per softgel: Each softgel provides 25 mcg of vitamin D3 as cholecalciferol. The NHS suggests 10 mcg a day for most adults, so this softgel provides more than that amount.
• One softgel a day with food: The suggested adult use is a single softgel daily with food.
• Olive oil softgel: Each softgel is made with extra virgin olive oil in a gelatin shell.
• Free from gluten and soy: The manufacturer states the product is gluten free, soy free and non-GMO.

What does vitamin D do in the body?

Vitamin D contributes to the normal function of the immune system. It also contributes to the maintenance of normal bones and to the normal absorption and use of calcium and phosphorus.

How does 25 mcg compare with the NHS advice on vitamin D?

The NHS says children from 1 year and adults need 10 mcg (400 IU) of vitamin D a day. It advises most people to consider a daily 10 mcg supplement in autumn and winter, when sunlight is not strong enough for the body to make it. One of these softgels provides 25 mcg, so it is a higher-strength option than the 10 mcg amount the NHS mentions.

Is this vitamin D3 supplement suitable for vegetarians or vegans?

The softgel shell contains gelatin. If you avoid animal-derived ingredients, check this before buying.

Active ingredient: Vitamin D3 (as cholecalciferol), 25 mcg (1000 IU) per softgel.

Additional information: The manufacturer states this product is non-GMO, gluten free and soy free.

Please note the following before taking this supplement:

• Do not take more than 100 mcg (4,000 IU) of vitamin D a day from all sources, as it could be harmful. The NHS applies this limit to adults, including pregnant and breastfeeding women and older people.
• This product's directions are for adults only. The NHS gives lower daily limits for children, so do not give these softgels to a child without advice from a doctor or pharmacist.
• If you have a medical condition, or your doctor has recommended a different amount of vitamin D, follow their advice.
