CoQ10 Improves Egg and Embryo Quality

 

By Margaret Eich, MS, RDN

An exciting new study shows promising results for CoQ10 supplementation in women with poor ovarian reserve doing IVF. In the study, 186 women under age 35 with poor ovarian reserve, defined as Anti-Müllerian hormone (AMH) < 1.2 ng/mL, and antral follicle count (AFC) < 5, were randomized to receive either treatment with 600 mg CoQ10 (200 mg 3 times per day) or control (no treatment) for 60 days leading up to their IVF cycle.

The results were pretty striking. The CoQ10 group had significantly more high quality day 3 embryos (1 vs. 0 in the control group), significantly less gonadotropins needed for stimulation, significantly more eggs retrieved (4 vs. 2 in the control group), and significantly higher fertilization rate (67% vs. 45% in the control group). In addition, significantly more patients who took CoQ10 had embryos to freeze (18.4% vs. 4.3% in the control group). The CoQ10 group also had higher pregnancy rates (32% vs. 17% in the control group) and higher live birth rates (29% vs. 16% in the control group), but these results were not statistically significant.

CoQ10 is an antioxidant and plays an essential in energy production in our body cells, including maturing eggs. CoQ10 is thought to exert its beneficial effects by neutralizing free radicals that could damage the DNA or other structures within the egg. Damage to DNA can prevent fertilization or result in a nonviable embryo. In addition, because of CoQ10’s role in energy production, CoQ10 likely also supports the energy needs of maturing eggs, thus leading to better quality eggs and embryos.  CoQ10 tends to be a safe and well-tolerated supplement, and in this study, there were no adverse effects reports from supplementing with CoQ10.

Absorption of CoQ10 is best when the dose is divided into 3 doses with meals during the day. Because CoQ10 is fat-soluble, having fat with CoQ10 increases the absorption. Learn more about our CoQ10 supplement here.
