Frequently Asked Questions

Why is a high-strength vitamin D3 supplement important for those living in the UK?
Sunlight is limited in the UK, especially from October to April, when the body produces little vitamin D. This supplement provides 1000 IU of vitamin D3, which contributes to the maintenance of normal bones and muscle function and to the normal function of the immune system.
What does vitamin D3 contribute to?
Vitamin D3 contributes to the normal absorption of calcium, the maintenance of normal bones, teeth and muscle function, and the normal function of the immune system. These are authorised nutrient functions, supported as part of a balanced diet.
Is 1000 IU Vitamin D3 safe to take daily?
Yes. The safe upper limit for adults is 4000 IU daily as established by EFSA. Pure Vitamins D3 provides 1000 IU using Cholecalciferol - the most bioavailable form of vitamin D3.
Can vegans take this Vitamin D3 supplement?
Yes. It uses a 100% vegan formula - no animal-derived gelatin or lanolin-based D3. Suitable for vegans and vegetarians, gluten-free and free from artificial additives.
When is the best time to take Vitamin D3?
Take one tablet daily with a meal containing healthy fats for best absorption. Vitamin D3 is fat-soluble, so taking it with food improves bioavailability. Consistent daily use is key.
