Jury still out on Vit D supplement benefits

Vitamin D supplementation, with or without calcium, does not improve skeletal, vascular or cancer outcomes among community-dwelling consumers by more than 15 per cent, a large meta-analysis of clinical trials has revealed.

New Zealand researchers analysed nine trials (48,647) patients for the impact of vitamin D supplementation on myocardial infarction or ischaemic heart disease outcomes, eight trails (46,131 patients) for stroke or cerebrovascular disease, seven trails (48,167 patients) for cancer outcomes and 22 trials (76,497 patients) for total fracture outcomes.
