The Role of CoQ10 (Coenzyme Q10) in IVF Preparation

Posted on

Coenzyme Q10, commonly known as CoQ10, is a vital compound that plays a crucial role in the energy production within our cells.

When it comes to preconception, both partners should be aware of the significance of CoQ10 and how it can positively impact conception and overall health.

What is CoQ10?

CoQ10 is a naturally occurring antioxidant and coenzyme found in every cell of the body. It is essential for the production of adenosine triphosphate (ATP), which is the primary source of energy for cellular functions. Besides its role in energy production, CoQ10 also acts as a potent antioxidant, protecting cells from oxidative damage.

Ubiquinol vs. Ubiquinone

CoQ10 exists in two main forms: Ubiquinol and Ubiquinone. The primary difference between these two forms lies in their structure and function within the body.


Ubiquinol is the active form of CoQ10. In this form, it is readily available for the body to use directly without the need for further conversion. This makes Ubiquinol highly bioavailable and efficient. It is particularly beneficial for individuals who may have difficulty converting Ubiquinone into its active form, such as older adults or those with certain health conditions.


Ubiquinone, on the other hand, is the oxidized form of CoQ10. While it can still be converted into Ubiquinol in the body, this conversion process becomes less efficient as we age or in situations where the body's natural processes are compromised. Therefore, Ubiquinone supplements may require higher dosages to achieve the same level of effectiveness as Ubiquinol.

For individuals planning for conception, Ubiquinol is recommended due to its superior bioavailability and direct usability by the body. The recommended dosage of Ubiquinol during preconception is typically around 200mg daily, which is considerably lower than some recommendations for Ubiquinone.

Before starting any CoQ10 supplementation, it's essential to consult with a healthcare professional to determine the appropriate form and dosage based on your individual needs.

Benefits for Both Men and Women

During preconception, the health and vitality of both partners are of utmost importance. CoQ10 can benefit both men and women in several ways:

For Women:

  • Improved egg quality: CoQ10 may enhance egg quality and support overall reproductive health in women.
  • Enhanced fertility: Some studies suggest that CoQ10 supplementation may improve fertility by supporting the energy needs of reproductive cells.
  • Antioxidant protection: CoQ10's antioxidant properties can help protect reproductive cells from damage caused by free radicals.

For Men:

  • Sperm health: CoQ10 has been linked to improved sperm motility and count, potentially increasing the chances of successful fertilization.
  • Antioxidant support: Like in women, CoQ10's antioxidant abilities can protect sperm cells from oxidative stress, maintaining their quality.

Food Sources of CoQ10

You can obtain CoQ10 through your diet. Some food sources rich in CoQ10 include:

  • Fatty fish (such as salmon, mackerel, and sardines)
  • Spinach and broccoli
  • Nuts and seeds
  • Whole grains

While you can incorporate these foods into your diet, it may be challenging to get an optimal amount of CoQ10 solely from food sources. Therefore, many individuals consider CoQ10 supplementation.

Kaneka Ubiquinol CoQ10

Our CoQ10 supplement contains the superior Ubiquinol form in the recommended 200mg dose (per two capsules).

We use Kaneka Ubiquinol™, which is the world's most researched and recognised CoQ10 ingredient, naturally produced by yeast fermentation.

We recommend two capsules per day for both partners during conception and IVF preparation. Always consult with a healthcare provider before taking any new supplement.
