In patients with diabetes, chronic inflammation is characterised by the increase in C-reactive protein (CRP) and tumour necrosis alpha (TNF-α). The consumption of melatonin and flaxseed oil may improve insulin sensitivity and the effectiveness of diabetic medications. The current study investigated the efficacy of melatonin and flaxseed oil in patients with Type 2 diabetes mellitus (T2DM). It involved 43 patients with diabetes who were divided into 3 groups. The first group received a placebo (starch 50mg, n=13), the second group received melatonin (10mg per day, n=14) and the third group received flaxseed oil (1000mg per day, n=16), in addition to prescribed hypoglycaemic medication and a 12-week controlled diet. Fasting blood sugar (FBS), glycated haemoglobin (HbA1c), oxidative stress and inflammatory parameters were measured in each group at 0, 6, and 12 weeks. Melatonin and flaxseed oil administrations resulted in a highly significant increase in glutathione (GSH) levels, a significant decrease in malondialdehyde (MDA), a significant increase in superoxide dismutase (SOD) in the melatonin group and a significant increase in SOD in the flaxseed oil group. The melatonin group and the flaxseed oil group also showed a highly significant decrease in oxidised low-density lipoprotein (ox-LDL).TNF-α was significantly reduced after the respective consumption of melatonin and flaxseed oil. Furthermore, flaxseed oil consumption resulted in a significant decrease in CRP; however, there was no significant difference in CRP due to melatonin consumption.
