Understanding the Difference Between Ubiquinol and Ubiquinone: Key Insights for Fertility and Health

Posted on

When sourcing Coenzyme Q10 (CoQ10) for fertility, mitochondrial function, and overall health, it's essential to understand the differences between Ubiquinol and Ubiquinone.

Both are forms of CoQ10, but they differ in chemical structure, absorption rates, antioxidant properties, and their ability to support fertility. This distinction is especially crucial for those trying to optimise their reproductive health.

15 years ago, when I became interested in Ubiquinol  there was limited evidence on how CoQ10 could support fertility. But thanks to ongoing research, we now have a clearer understanding, which has led to more informed decisions in supplement sourcing. - Zita West

For example, Kaneka Ubiquinol is often chosen for its superior bioavailability and efficacy.

Here’s a breakdown of the key differences:

1. Chemical Structure and Active Form

Ubiquinol is the reduced (active) form of CoQ10. This means it is electron-rich and ready to act as a powerful antioxidant in the body, protecting cells from oxidative damage.
Ubiquinone is the oxidised form of CoQ10. It needs to be converted into ubiquinol by the body before it can become effective in its antioxidant and energy-boosting roles.

2. Absorption and Bioavailability

Ubiquinol is the most bioavailable and absorbable form of CoQ10. Studies show that Kaneka Ubiquinol (used in premium supplements like those from Zita West) has significantly higher absorption compared to ubiquinone. This makes it especially beneficial for individuals over 35 or 40, as the body's ability to convert ubiquinone into ubiquinol declines with age.

Ubiquinone requires conversion into ubiquinol to be utilised by the body. As we age or if we have specific health conditions, this conversion becomes less efficient.

3. Antioxidant Properties

Ubiquinol acts as a potent antioxidant. It helps neutralise harmful free radicals that can damage cells, including eggs and sperm. This is crucial for fertility, as oxidative stress can negatively impact egg quality, sperm motility, and overall reproductive health.
Ubiquinone also has antioxidant properties but must be converted into ubiquinol to provide maximum protection against oxidative damage.

4. Energy Production and Mitochondrial Support

Both forms of CoQ10 play an essential role in energy production within the mitochondria, the cell's "powerhouses." However, Ubiquinol is the active form that directly contributes to the production of ATP (adenosine triphosphate), the energy currency needed for cellular functions.

Ubiquinone must first be converted to ubiquinol to contribute to energy production, making it a less efficient form for those with reduced conversion abilities, especially in older adults.

5. Fertility and Supplementation Preferences

Ubiquinol is particularly recommended for individuals looking to improve fertility, boost energy levels, and promote overall cellular health. Premium fertility brands, such as Zita West, choose Kaneka Ubiquinol for its superior absorption and efficacy, ensuring it supports egg quality and sperm health.

For both male and female fertility, Kaneka Ubiquinol helps reduce oxidative stress, support mitochondrial function, and improve the quality of eggs and sperm. It is essential for individuals who are trying to conceive naturally or through assisted reproductive technologies (ART).

While Ubiquinone still offers benefits, its conversion to the active form (ubiquinol) is less efficient in individuals over 35 or those with compromised conversion abilities.

Why Zita West Chooses Kaneka Ubiquinol for Fertility Support

For a long time now I have encouraged women and men to uses Kaneka Ubiquinol in their supplements because it is the best-absorbed form of CoQ10. - Zita West

This ensures that individuals using Zita West products receive maximum benefits for:

  • Enhancing egg quality. Learn more about CoQ10 and egg health here.
  • Enhancing sperm health. Learn more about CoQ10 and sperm health here.
  • Supporting mitochondrial function and cellular health
  • Reducing oxidative damage, which is critical for optimal reproductive health

Kaneka Ubiquinol has been extensively researched and shown to be the most bioavailable and effective form of CoQ10 supplementation. By incorporating Kaneka Ubiquinol, Zita West ensures their products are of the highest quality, providing the best possible outcomes for fertility, whether through natural conception or assisted reproductive technologies.

Why Ubiquinol Is Crucial for Male and Female Fertility

Both male and female fertility benefit from Ubiquinol’s powerful antioxidant properties. For women, it helps protect eggs from oxidative damage, improving egg quality and supporting mitochondrial function, which is vital during fertilisation. For men, Ubiquinol supports sperm motility and count, increasing the chances of successful conception. With the body’s ability to convert ubiquinone into ubiquinol diminishing with age, supplementing with the active form ensures maximum support for fertility.

By choosing a high-quality Ubiquinol supplement like Kaneka Ubiquinol, individuals can optimise their fertility health, supporting both the quality of eggs and sperm, energy production, and reducing the effects of oxidative stress.
