AIM: According to many studies, supplementation with Coenzyme Q10 (CoQ10) yields beneficial results in terms of endothelial function in type 2 diabetes mellitus. Despite these promising results, data elucidating the effect of CoQ10 on plasma levels of Asymmetric dimethylarginine (ADMA), as a recently discussed cardiovascular risk factor, is lacking. This study was designed to investigate the effect of CoQ10 supplementation on endothelial function, specifically by evaluating plasma ADMA levels.

METHODS: Sixty-four type 2 diabetic patients were randomly assigned to two groups; either receiving 200mg/d oral dose of CoQ10 (n=31) or receiving placebo (n=33) for 12 weeks. Clinical and biochemical assessments were performed before and after the trial for evaluating ADMA, serum nitrite and nitrate (NOx), hemoglobin A1c and lipid profile.

RESULTS: The intervention resulted in a significant improvement in ADMA, NOx , low-density lipoprotein and hemoglobin A1c levels in CoQ10 compared to placebo group. Interestingly, difference in changes of these parameters were also significant ( P= 0.01, 0.03, 0.04 and 0.03, respectively).

CONCLUSION: Supplementation with CoQ10 yields beneficial effects on ADMA levels, leading to decreased diabetic cardiovascular events.
