Scientific background
Independent researchVitamin D3 (cholecalciferol)
Vitamin D is made in the skin in sunlight and is found in a few foods. It is needed for calcium absorption and bone health. EFSA set an adequate intake of 15 µg (600 IU) a day for adults2. 1 µg equals 40 IU.
Research evidence
Independent researchVitamin D3 (cholecalciferol)
Authorised EU claims include that vitamin D contributes to the maintenance of normal bones, muscle function and immune function3.
In the large VITAL trial, 2000 IU (50 µg) a day of vitamin D3 did not lower the incidence of invasive cancer or major cardiovascular events compared with placebo4. A meta-analysis found that vitamin D supplements did not prevent fractures or falls, or have clinically meaningful effects on bone density5.

Long-term intakes above this level can raise blood calcium and harm the kidneys. High-dose products should only be used on medical advice.
