DWM VIT D X REDUCES RISK OF CA

Association Between Vitamin D Supplementation and Mortality

BMJ : British Medical Journal

TAKE-HOME MESSAGE

• Previous evidence indicates an inverse association between vitamin D levels and mortality due to cancer and cardiovascular disease. However, the effectiveness of vitamin D supplementation for reducing mortality is not clear. Hence, this systematic review and meta-analysis of 52 trials on vitamin D supplementation looked at whether such supplementation reduced the mortality rates in adults.

• Although there was no association between vitamin D supplementation alone and all-cause mortality compared with placebo or no treatment, it did reduce the risk of mortality due to cancer.
