Vitamin D helps prevent cardiovascular disease
This question is a bit vague. There are two ways to make it more specific.
1. Does vitamin D defficiency increase the risk of cardiovascular disease?
(Yes) This population study shows “low serum 25(OH)D levels are associated with a higher prevalence of PAD.”
2. Does supplementing additional vitamin D help prevent cardiovascular disease?
(No) Correlational study: “serum levels of 1,25-(OH)2-vitamin D were found to be inversely correlated to the blood pressure…”
(No) A meta-study concluded “vitamin D and/or calcium supplementation also showed no overall effect on CVD, cancer, and mortality.”
(No) Another meta-analysis concluded “the effect estimate for vitamin D supplementation with or without calcium for myocardial infarction or ischaemic heart disease… lay within the futility boundary, indicating that vitamin D supplementation does not alter the relative risk of any of these endpoints by 15% or more.”
(No) And yet another meta-analysis showed no effect as well.

Should we break this into two wiki pages?
Yes, but there is not a lot of content, so I’m keeping it as one for now.
