The Role of CoQ10, Omega-3s, and Antioxidants in Egg Quality

By Natalie Stradiotto, Naturopathic Doctor | Dalhousie Health & Wellness, Port Dalhousie, St. Catharines

When trying to conceive—whether naturally or through assisted reproductive technologies like IVF--egg quality is one of the most important factors influencing success. Unlike sperm (which renews continuously), women are born with all the eggs they will ever have. Over time, oxidative stress, nutrient depletion, and environmental exposures can negatively impact the mitochondrial function and DNA integrity of these eggs. The encouraging news is that research shows specific nutrients and antioxidants can help protect and support egg quality, potentially improving outcomes for conception and embryo development. In this post, we’ll explore how CoQ10 and omega-3 fatty acids support reproductive health. (In a future post, we’ll dive deeper into the benefits of an antioxidant-rich diet for fertility.)

How CoQ10 Supports Egg Quality

CoQ10 (in the forms of ubiquinone or ubiquinol) plays a critical role in mitochondrial energy production. Since egg cells require significant energy for maturation and division, optimal mitochondrial function is essential.
CoQ10 also acts as a powerful antioxidant, helping to neutralize free radicals that can damage developing follicles.

Research Highlights
    •    Studies in women undergoing IVF have shown:
    ◦    Improved response to ovarian stimulation
    ◦    Increased number of mature eggs
    ◦    Higher fertilization rates

How Omega-3 Fatty Acids Support Fertility

Omega-3 fatty acids are essential fats that contribute to overall reproductive health by supporting:
    •    Hormone production and balance
    •    Cell membrane integrity (critical for egg and embryo health)
    •    Anti-inflammatory pathways, which are key for ovulation and implantation
They also help regulate prostaglandins, improving ovarian and uterine blood flow.
​
Research Highlights
    •    Omega-3 supplementation has been associated with:
    ◦    Improved oocyte (egg) quality
    ◦    Better embryo morphology
    ◦    Potentially higher pregnancy rates in some IVF populations
