The skeptic movement is a collective endeavor that promotes the respect for knowledge and truth, methodological naturalism, science, reason, critical thinking, and consumer protection, and aims to distinguish legitimate science from pseudoscience, uphold ideological freedom, understand cognitive biases, address specific flawed or pseudoscientific claims, maintain cultural memory of past pseudosciences and scams, and improve science communication and journalism.

This article discusses the effects of vitamin D supplementation on major cardiac events, based on a large randomized controlled trial, the D-Health Trial.

The trial involved 21,315 older Australians and aimed to assess the impact of monthly vitamin D supplementation (60,000 IU) on the incidence of major cardiovascular events. The study found no significant difference in the rate of major cardiovascular events between those receiving vitamin D and those receiving a placebo.

However, a few individual events showed statistically significant differences, albeit very slight. Despite these minor positive results, the trial overall adds to existing research suggesting that vitamin D supplementation offers no significant cardiovascular benefits.

What about depression and other believed benefits like a functioning immune system

Tl;dr:

A study published in The BMJ suggests vitamin D might prevent autoimmune disease, but there are reasons to be cautious
A randomized controlled trial finds vitamin D supplementation has no effect on depression. This adds to the long list of medical conditions for which vitamin D supplementation has turned out to be ineffective.
