Background: Increased levels of reactive oxygen species is a key factor involved in the pathogenesis of type 2 diabetes mellitus (T2DM). Coenzyme Q10(CoQ10) is a nonenzymatic antioxidant that restores other antioxidants. Materials and Methods: This randomized, double-blind placebo-controlled trial study has been designed to evaluate the effects of CoQ10supplementation on serum values of amylase, adenosine deaminase, catalase (CAT), total antioxidant capacity (TAC) and the quantitative insulin sensitivity check index (QUICKI) in women with T2DM. Serum levels of CoQ10were measured too. Sixty-eight women with T2DM were enrolled in this study and randomly divided into two groups. One group received 100 mg/day of CoQ10supplement for 12 weeks (n = 34), and the other group was given placebo for the same time duration and dosage (n = 34). Results: After the intervention, serum CAT activity (P < 0.001), TAC (P = 0.006), CoQ10(P = 0.001), and QUICKI (P = 0.005) increased and fasting blood sugar (FBS) (P = 0.05) decreased significantly in CoQ10group. Conclusion: This study showed that daily supplementation with 100 mg of CoQ10could increase TAC and CAT activity as, CoQ10and QUICKI and could reduce oxidative stress and FBS in women with T2DM.
