A randomized controlled trial was evaluated in a meta-analysis on vitamin D and cancer recently published in the British Journal of Cancer.

The studies lasted 2-7 years and the vitamin D doses used varied between 400 and 1,100 IU per day. The authors of the Harvard School of Public Health came to the following conclusion on the basis of these studies: Cancer mortality is significantly reduced by 15% with the aid of an additional vitamin D intake. The researchers illustrate the result strikingly on the example of the United Kingdom: They expect that this alone on the island probably tens of thousands of people could be saved from cancer death.
