Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Vitamin D has been studied in relation to cardiovascular health, including the concept of "heart weakness" (which may refer to heart failure or general cardiac function). Epidemiological studies have shown that low levels of vitamin D are associated with an increased risk of cardiovascular diseases, including heart failure. Vitamin D receptors are present in heart muscle cells and vascular tissue, and vitamin D is thought to influence blood pressure regulation, inflammation, and myocardial function.

However, randomized controlled trials (RCTs) investigating vitamin D supplementation for the prevention or treatment of heart failure or improvement of heart function have yielded mixed results. Some trials suggest a modest benefit in certain populations, such as those with severe vitamin D deficiency, but large meta-analyses and guidelines generally conclude that there is insufficient evidence to recommend vitamin D supplementation solely for improving heart function in individuals without deficiency. The American Heart Association and other major cardiology societies do not endorse vitamin D supplementation specifically for heart weakness unless a deficiency is present.

In summary, while there is a biological rationale and some observational evidence linking vitamin D status to heart health, robust clinical evidence supporting routine vitamin D supplementation for heart weakness is limited. Its use in this context is based on a mix of suggestive but inconclusive scientific findings, resulting in a moderate to low rating for evidence support.
