According to this study by Iranian and Canadian researchers, co-supplementation with vitamin D and omega-3 fatty acids improves several factors increasing the risk for cardiovascular diseases in type 2 diabetic patients. The study was executed with 61 vitamin D-deficient diabetic patients with coronary heart disease. The participants were allocated to either a group receiving 50000 IE (1250 µg) vitamin D supplements every two weeks in combination with 1000 mg omega-3 fatty acids (30 participants) twice per day or they received a placebo (31 participants) for six months. Co-supplementation of the mentioned micronutrients significantly reduced fasting glucose, LDL-cholesterol levels, and pro-inflammation markers. Furthermore, the supplements increased HDL-cholesterol levels, which is known as the “good” cholesterol because it helps remove other forms of cholesterol from the bloodstream. In summary, vitamin D and omega-3 co-supplementation have beneficial effects in diabetic patients with coronary heart disease. More details can be found in the study.
