CoQ10 and Fertility: Why It’s Important for Conception

Coenzyme Q10 (CoQ10) is a crucial nutrient for cellular energy production and is gaining attention for its role in fertility health. Whether you are just starting your fertility journey, facing challenges, or pursuing assisted reproductive techniques like IVF, CoQ10 may be a valuable addition to your supplement plan.

This guide explains why CoQ10 is important for both natural conception and assisted fertility methods.

What is CoQ10?

CoQ10, short for coenzyme Q10, is a powerful antioxidant naturally produced in the body, essential for energy production within cells. As we age, natural CoQ10 levels decline, potentially affecting cellular health, including that of reproductive cells like eggs and sperm. Supplementing with CoQ10 can help support the energy requirements of these cells, which is critical for conception.

Why CoQ10 is beneficial for fertility

There are several reasons why CoQ10 is particularly relevant for fertility:

• Energy production: Fertility relies heavily on cellular energy, particularly within the ovaries and testes. CoQ10 supports mitochondria, the cell's energy powerhouse, boosting egg quality and sperm motility.
• Antioxidant protection: CoQ10 neutralises harmful free radicals, which can damage cells including eggs and sperm. Oxidative stress is known to affect fertility negatively, especially as we age.

CoQ10 and female fertility

For women, CoQ10 is particularly relevant for supporting egg quality, especially for those over 35 where ovarian ageing accelerates and reduces both the quality and quantity of eggs. In a recent study, CoQ10 levels in women with premature ovarian insufficiency (POI) were compared to those with normal ovarian function. Women with POI had a lower ratio of CoQ10 to total cholesterol, suggesting that reduced CoQ10 levels may increase the risk of POI through oxidative stress.

By supporting cellular energy and protecting eggs from oxidative damage, CoQ10 may benefit fertility in the following ways:

• Supporting egg development for natural conception
• Improving response to ovarian stimulation in IVF cycles
• Enhancing embryo quality, contributing to better IVF outcomes

CoQ10 and male fertility

Male fertility is equally supported by CoQ10. This antioxidant has been shown to improve sperm motility and concentration, both critical factors for conception. CoQ10 increases energy production within sperm cells and protects them from oxidative stress, which can damage DNA and reduce fertility.

In a recent study, CoQ10 supplementation led to significant improvements in sperm quality and higher conception rates.

Choosing the best CoQ10 supplement for fertility

Not all CoQ10 supplements are equal. When looking for the best CoQ10 for fertility, the two most important factors are form and bioavailability.

1. Form of CoQ10: Ubiquinol is the active form of CoQ10 and is more readily absorbed than ubiquinone, making it the preferred choice for those looking to optimise fertility. The body's ability to convert ubiquinone into ubiquinol also declines with age, making ubiquinol particularly important for women over 35.
2. Bioavailability: Research shows that Kaneka Ubiquinol is up to 70% more bioavailable than standard CoQ10 supplements. Read the research behind Kaneka Ubiquinol here.

Each two capsule dose provides 200mg of CoQ10, which is based on the latest research for natural conception. For those who have been advised to take a higher dose of 400 to 600mg, we recommend splitting servings throughout the day and avoiding taking them at night. Always consult with a healthcare provider for individual dosage guidance. For a full breakdown of dosage recommendations, read our CoQ10 dosage guide here.

How to incorporate CoQ10 into your fertility plan

CoQ10 can benefit a range of individuals on their fertility journey:

• For those trying naturally: CoQ10 supports overall reproductive health, helping to optimise egg and sperm quality.
• If you are facing difficulties conceiving: CoQ10 may improve oocyte quality, sperm motility and embryo viability, supporting your chances of success.
• For those undergoing IVF: CoQ10 is frequently discussed by fertility specialists as a way to support IVF outcomes, potentially improving fertilisation and embryo quality. For timing guidance specific to IVF, read our timing guide here.

How long to take CoQ10 for fertility support

Starting CoQ10 at least three months before trying to conceive or beginning fertility treatments gives the supplement time to support egg and sperm quality through a full development cycle. Continuing supplementation throughout your fertility journey is generally recommended for ongoing benefits. For a full guide to timing, read our CoQ10 timing guide here.

Are there any side effects?

CoQ10 is generally safe and well tolerated. Some individuals may experience mild digestive discomfort, particularly at higher doses. Always speak with a healthcare provider before beginning any new supplement, especially if you are undergoing fertility treatments or have existing health concerns.

CoQ10 is a well-researched fertility supplement for those looking to optimise their reproductive health, from natural conception to IVF. Its role in cellular energy production and antioxidant support makes it particularly relevant for egg and sperm quality.
