High dosage vitamin D unlikely to prevent cancer or heart attacks

14-Nov-2018

Key points from article :

Study tested more than 25,000 adults over the age of 50 in the US over 5 years.

Randomised controlled trial (RCT) of high-dose (50mcg) vitamin D.

No difference in the number of people who developed cancer or cardiovascular disease.

No different in deaths from any cause.

These chronic diseases can take a long time to develop.

Most people had vitamin D levels above the recommended level at start of study.

The study was published in The New England Journal of Medicine.

Would be interesting to compare to people with low vitamin D blood levels
