Abstract
BACKGROUND: Diabetes mellitus is a chronic disease manifested by an increase of blood glucose. OBJECTIVE: To evaluate the effects of glucan and vitamin D supplementation in patients with diabetic retinopathy. METHOD: We evaluated the effects of 3-month supplementation with glucan and vitamin D in 54 patients with diabetic retinopathy. We measured levels of vitamin D, cholesterol, HDL cholesterol, and triglycerides. RESULTS: The supplementation strongly decreased the cholesterol levels and improved the levels of HDL cholesterol. In addition, vitamin D levels were strongly improved, but still not at optimal values. CONCLUSION: From our data, we concluded that glucan and vitamin D supplementation strongly influence lipid metabolism and have positive effects on human health.
