Scientific evidence shows that a deficiency of different micronutrients, including vitamin D, is associated with coronary artery disease, which occurs when the heart’s blood supply is blocked or interrupted by a build-up of fatty substances in the coronary arteries. Therefore, this Chinese study researched the effects of vitamin D supplementation on the severity of this disease. 90 coronary artery disease patients received either 0.5 µg vitamin D per day or a placebo. Before and after 6 months of treatment, vitamin D levels were measured, the condition of the coronary arteries was investigated, and the severity of coronary artery disease was assessed. Patients in the supplementation group showed significantly increased vitamin D levels, decreased inflammation markers, and reduced severity of coronary artery disease. In conclusion, vitamin D supplementation has beneficial effects on coronary artery disease and may provide an efficient therapeutic option. More details can be found in the study.
