If you have started researching preconception nutrition, you have probably come across CoQ10 more than once. It shows up in fertility forums, practitioner recommendations and good quality preconception multivitamins. With so many nutrients competing for attention, it is reasonable to want to understand what CoQ10 actually is before deciding whether it belongs in your routine.
What Is CoQ10
Coenzyme Q10, or CoQ10, is a naturally occurring compound found in almost every cell in the body. It plays a central role in cellular energy production and also acts as an antioxidant, helping to reduce free radical damage to body cells. CoQ10 is produced naturally by the body, but levels are known to decline with age, which is one reason it has become a focal point in preconception nutrition conversations, particularly for women and men in their thirties and beyond.
CoQ10 and Mitochondrial Health
Mitochondria are often described as the energy factories of the cell, and this is especially relevant to reproductive cells. Eggs and sperm are among the most energy demanding cells in the body, requiring a substantial mitochondrial supply to support their development. Because CoQ10 is concentrated in the mitochondria and plays a direct role in energy production, it is frequently discussed in relation to supporting the cellular energy needs of reproductive cells during the preconception period.
CoQ10 and Egg Quality
Egg quality is a common concern for women planning pregnancy, particularly as age increases. Research has explored whether CoQ10 supplementation may support outcomes in women undergoing fertility treatment, with interest centering on its antioxidant role in protecting eggs from oxidative stress within the follicular environment. This remains an area of ongoing research interest and CoQ10 should be considered one part of a broader approach to preconception health rather than a standalone solution.
CoQ10 and Sperm Quality
CoQ10 has also been studied in relation to male reproductive health, with particular interest in sperm motility. Sperm cells rely heavily on mitochondrial energy to move effectively, and oxidative stress is understood to be one factor that can affect sperm function over time. This is why CoQ10 is commonly included alongside other antioxidants, such as vitamins A, C, E and lycopene, in preconception formulations designed for men.
Ubiquinol vs Ubiquinone and Ubidecarenone
CoQ10 exists in two main forms: ubiquinone also known as ubidecarenone, the oxidised form, and ubiquinol, the reduced form that carries most of the antioxidant activity. The body is able to convert between the two forms as needed. You may see either term used on supplement labels, and while conversation around absorption differences between the two forms continues, both are recognised forms of CoQ10 used in preconception nutrition.
CoQ10 Dosage for Reproductive Health
Preconception CoQ10 research has used a range of doses, and there is no single figure that suits everyone. This is why formulation quality matters as much as the ingredient itself. NaturoBest's Preconception Multi for Women and Preconception Multi for Men each provide 100mg of CoQ10 in the daily dose, a meaningful amount not commonly found in general prenatal or preconception multivitamins, alongside other targeted nutrients suited to preconception health.
When to Start Taking CoQ10 Before Pregnancy
Because eggs and sperm take around three months to mature, many practitioners suggest beginning preconception nutrition, including CoQ10, at least three months before actively trying to conceive. This timeframe allows cellular energy support to be in place throughout the maturation process, rather than being introduced only once conception is already being attempted.
Frequently Asked Questions
What does CoQ10 do for reproductive health?
CoQ10 supports the mitochondrial energy production that reproductive cells rely on and helps reduce free radical damage to body cells, which is why it features in preconception nutrition for both women and men.
Does CoQ10 improve egg quality?
Research has looked at whether CoQ10 supplementation may support egg quality by protecting against oxidative stress, though outcomes vary and it should be viewed as one part of a broader preconception approach.
How long before conception should you take CoQ10?
Many practitioners recommend starting around three months before trying to conceive, in line with the natural maturation cycle of eggs and sperm.
Is CoQ10 okay to take while trying to conceive?
CoQ10 is a naturally occurring compound already present in the body and is commonly included in preconception formulations. As with any supplement, discuss your individual circumstances with your health practitioner.
What is the difference between ubiquinol and ubiquinone?
Ubiquinone/Ubidecarenone is the oxidised form of CoQ10 and ubiquinol is the reduced, antioxidant active form. The body converts between the two as required.
Can men take CoQ10 for sperm health?
Yes, CoQ10 is commonly included in preconception formulations for men, with particular interest in its role supporting sperm motility and antioxidant protection.
How much CoQ10 should I take preconception?
Doses used in research vary, which is why the overall formulation matters. NaturoBest's Preconception Multi range provides 100mg of CoQ10 daily for both women and men.
Does age affect CoQ10 levels in eggs?
CoQ10 levels are understood to decline with age, which is part of why it is discussed more often in preconception nutrition for men and women in their mid-thirties and beyond.
A Note on Preconception Nutrition
CoQ10 is one piece of a much larger preconception picture that includes folate, iodine, vitamin B12, zinc and overall diet quality.
If you are exploring your options, NaturoBest's Preconception Multi for Women and Preconception Multi for Men were formulated with this full picture in mind, each containing 100mg of CoQ10 alongside nutrients such as hydroxocobalamin, zinc citrate and, for men, lycopene and vitamin E.
