It is known that there is a significant interplay of insulin resistance, oxidative stress, dyslipidemia, and inflammation in type 2 diabetes mellitus (T2DM). The study was undertaken to investigate the effect of turmeric as an adjuvant to anti-diabetic therapy. Sixty diabetic subjects on metformin therapy were recruited and randomized into two groups (30 each). Group I received standard metformin treatment while group II was on standard metformin therapy with turmeric (2 g) supplements for 4 weeks. The biochemical parameters were assessed at the time of recruitment for study and after 4 weeks of treatment. Turmeric supplementation in metformin treated type 2 diabetic patient significantly decreased fasting glucose (95 ± 11.4 mg/dl, P < 0.001) and HbA1c levels (7.4 ± 0.9 %, P < 0.05). Turmeric administered group showed reduction in lipid peroxidation, MDA (0.51 ± 0.11 µmol/l, P < 0.05) and enhanced total antioxidant status (511 ± 70 µmol/l, P < 0.05). Turmeric also exhibited beneficial effects on dyslipidemia LDL cholesterol (113.2 ± 15.3 mg/dl, P < 0.01), non HDL cholesterol (138.3 ± 12.1 mg/dl, P < 0.05) and LDL/HDL ratio (3.01 ± 0.61, P < 0.01) and reduced inflammatory marker, hsCRP (3.4 ± 2.0 mg/dl, P < 0.05). Turmeric supplementation as an adjuvant to T2DM on metformin treatment had a beneficial effect on blood glucose, oxidative stress and inflammation.
