Some preliminary studies link low vitamin D levels with disease later in life. One meta-analysis found a decrease in mortality in elderly people. Another meta-analysis covering over 350,000 people concluded that vitamin D supplementation in unselected community-dwelling individuals does not reduce skeletal (total fracture) or non-skeletal outcomes (myocardial infarction, ischemic heart disease, stroke, cerebrovascular disease, cancer) by more than 15%, and that further research trials with similar design are unlikely to change these conclusions. As of 2022, there is insufficient evidence for an effect of vitamin D supplementation on the risk of cancer. A 2019 meta-analysis found a small increase in risk of stroke when calcium and vitamin D supplements were taken together.
