BACKGROUND: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in reproductive age women.
OBJECTIVE: This study was conducted to investigate the effects of CoQ10 and/or vitamin E on cardiometabolic outcomes in patients with PCOS.
METHODS: This randomized clinical trial was carried out among 86 women with PCOS. Patients were assigned to take CoQ10, vitamin E, CoQ10 plus vitamin E or placebo for 8 weeks. Fasting blood samples were obtained at the beginning and end of the study.
RESULTS: A significant decrease in serum triglycerides (TG) (p <0.001) was found following the administration of CoQ10 and/or vitamin E supplements compared with the placebo group. Supplementation with CoQ10 and vitamin E failed to affect total cholesterol levels. However, co-administration of CoQ10 and vitamin E resulted in a significant decrease in serum total cholesterol levels (9.92 [15.11, 4.74]). Additionally, only the combination of supplements was able to significantly reduce low-density lipoprotein-cholesterol (LDL-C) (‒9.63 [‒15.34, ‒3.92]), increase high-density lipoprotein-cholesterol (HDL-C) (2.33 [0.51, 4.16), reduce atherogenic coefficient (AC) (‒0.29 [‒0.43, ‒0.16], p = 0.03) and decrease visceral adiposity index (VAI) values. Co-Q10 and vitamin E (alone or in combination) had significant effects on non-HDL-C (p = 0.004), atherogenic Index of Plasma (AIP) (p =<0.001) and lipid accumulation product (LAP) (p <0.001) and SBP (p = 0.005). However, the reduction in DBP was statistically significant only for patients who received combined supplementations (p = 0.04).
CONCLUSIONS: In conclusion, CoQ10, vitamin E (alone or in combination) had beneficial effects on cardiometabolic outcomes among women with PCOS.
