When it comes to your preconception journey, there are a number of lifestyle factors to keep in mind as you prioritize your wellness alongside your partner. Yet, you may be overlooking the value of a supplement containing ubiquinol for reproductive health support. In fact, research demonstrates that ubiquinol supports preconception health, thanks to ubiquinol’s antioxidant properties and role in cellular energy production. Below, we discuss why incorporating ubiquinol into your routine for preconception health is something you may want to consider.
Prioritizing your preconception health includes understanding your body on a cellular level. Ubiquinol promotes preconception health due to its vital role in cellular energy generation and antioxidant properties — key for protecting cells and tissues from free radical damage.
Oxidative stress, or an imbalance of free radicals (molecules seeking electrons) and antioxidants (molecules that share electrons), can occur for a number of reasons: poor diet, strenuous exercise, getting older, pollution, and other lifestyle habits. Oxidative stress can damage tissues and cells, including reproductive cells, and impact reproductive health.
Luckily, both you and your partner can take advantage of a Kaneka Ubiquinol® supplement. Both men and women can support their preconception health and protect their reproductive cells with a ubiquinol supplement.1,2 For men, ubiquinol promotes sperm motility, enhances sperm count, and promotes sperm quality.3,4 For women, ubiquinol supports the cellular energy processes required to maintain oocyte and egg health, which we explore further below.2,5,6

Ubiquinol can benefit preconception health in women in two important ways. Oocytes require a great deal of energy to develop and function properly and consequently have a very large number of mitochondria. This means they require high amounts of ubiquinol to support their energy demand. In fact, oocytes have the largest number of mitochondria in any cell, so having healthy mitochondria is essential for female reproductive cells to function properly.7
This makes ubiquinol key: Its antioxidant properties make it foundational for keeping free radicals at bay to protect oocytes from oxidative stress. These cells are particularly vulnerable to biological changes that occur with aging and environmental factors, making them more susceptible to cellular damage. Ubiquinol helps protect these reproductive cells from damage, and it is especially helpful to women who delay motherhood into their mid-30s and early-40s, as oxidative stress increases with age and can impact reproductive cells even more.7,8
Kaneka Ubiquinol® is not just ideal for women on their preconception journey — its antioxidant and other properties also benefit men’s reproductive cells and processes. In males, insufficient ubiquinol levels correlate with low sperm counts and sperm motility.1 Sperm require large amounts of energy and a healthy oxidative balance to develop and function properly.
Therefore, maintaining adequate ubiquinol levels to support energy production and neutralize free radicals is important to support reproductive health. Men prioritizing their preconception journey should consider taking a daily Kaneka Ubiquinol® supplement to promote healthy sperm function and overall health.3,4
While men and women have different biological factors to consider, they can both benefit from Kaneka Ubiquinol® on their preconception journey. Given ubiquinol’s antioxidant properties, its role in cellular energy production, and the high concentration of mitochondria in reproductive cells, Kaneka Ubiqiunol® supports oocyte and egg function and sperm health.
In general, for healthy adults, 100mg of ubiquinol daily is recommended. However, individual requirements will vary depending on your health status and goals. For preconception health support, starting with a higher dose of 200mg of ubiquinol daily may be helpful. Be sure to talk to your doctor or licensed healthcare provider to determine the right dosage for you.

Incorporating a Kaneka Ubiquinol® supplement into your regimen is easier than you might think. You can take it at any time of the day, and many people take ubiquinol in the morning with breakfast. If you take more than one ubiquinol capsule each day, consider taking them at different times — such as with breakfast and lunch. If you have trouble falling asleep, avoid taking ubiquinol in the evening.
Here are some simple hacks for working a supplement into your day-to-day routine:
Ubiquinol’s support for preconception health is just one of its many benefits. In fact, people of all ages and health goals can benefit from a ubiquinol supplement, thanks to its promotion of healthy mitochondrial function, cellular energy, and more.

If you’re worried that adding ubiquinol to your regimen might impact other supplements you’re taking, rest assured: Kaneka Ubiquinol® is a safe supplement that may be taken with other supplements you may already be taking, such as a prenatal vitamin, multi-vitamin, or mineral supplement. Also, most vitamin supplements do not contain ubiquinol because it’s a fat-soluble (rather than water-soluble) nutrient and is best delivered in a soft gel with a fat such as sunflower, rice bran oil, or olive oil. Talk to your doctor about adding Kaneka Ubiquinol® to your supplement regimen.
