An Iranian study aimed to evaluate the effects of selenium supplementation on the function of the metabolism, including glucose balance, inflammation levels, and oxidative stress in patients with diabetes type 2 and coronary heart disease. 60 patients were divided into two groups. For 8 weeks, the first group (30 patients) received 200 µg of selenium per day and the second group (30 patients) received a placebo. Fasting blood samples were taken at the start of the study and after 8 weeks of intervention. After 8 weeks, selenium supplementation resulted in a significantly improved glucose metabolism and a significant reduction of inflammation markers compared to patients in the placebo group. More details can be found in the study.
