Researchers at the University of Malaya in Malaysia just last month published their findings on the effects of vitamin D supplementation on cardiovascular health and health-related quality of life in healthy, pre-menopausal women:
Ramly M, Ming MF, Chinna K, Suboh S, Pendek R. Effect of Vitamin D Supplementation on Cardiometabolic Risks and Health-Related Quality of Life among Urban Premenopausal Women in a Tropical Country – A Randomized Controlled Trial. PLoS ONE. 2014;9(10):e110476.
Many observational studies have noted that people with more sun exposure have better cardiovascular health. This includes a more favorable lipid profile, lower blood pressure, and better insulin sensitivity. These benefits have been attributed to increased vitamin D production, but randomized controlled trials (RCT) have had conflicting results regarding the effects of vitamin D supplementation on cardiovascular markers.
