What is it?
What is it?
A high-dose, naturally-fermented CoQ10 supplement designed to support mitochondrial function and protect eggs from oxidative stress. One capsule taken twice daily delivers 800mg of ubiquinone, the form your body produces and the form used in clinical fertility research.
60 capsules = 30 day supply.
Who is it for?
Who is it for?
Women over 35 trying to conceive naturally: CoQ10 production declines from your mid-thirties, at exactly the time egg quality becomes a greater concern.
Preparing for IVF or egg freezing, the three months before egg collection is the window that matters most. Start at least 90 days before your planned retrieval date.
Women who've been trying for a while, if conception is taking longer than expected, egg quality is worth addressing even where other markers look normal.
Suitable for vegetarian and vegan diets. Free from allergenic ingredients.
How should I take it?
How should I take it?
Take one capsule twice daily, preferably with food, for example one capsule at breakfast and one at dinner.
CoQ10 is fat-soluble, so taking it with a meal that contains fat improves absorption.
Can be taken alongside Fundamental Woman, omega-3, myo-inositol and magnesium bisglycinate. Everything fits together with no gaps and no doubling up.
Most women start at least three months before they want to conceive or before their planned egg collection date.

Naturally Fermented Ubiquinone 400mg. The natural fermentation process yields the all-trans isomer, the same structural form found in human tissue.
Vegetable Capsule Shell (Hydroxypropylmethylcellulose): plant-based.
Bamboo Silica: a natural plant-derived ingredient that ensures the right amount of CoQ10 reaches the capsule every time.
That's it. Nothing else.
How is it different?
How is it different?
Naturally-fermented ubiquinone: the form your body recognises, not a synthetic version. A meaningful dose: 800mg per day across two capsules, not the token amounts found in most multivitamins.
Amber glass bottle: protects CoQ10 from light degradation and reduces exposure to plastic.
Made in the UK to GMP pharmaceutical standards.
Allergen information
This product is free from all 14 major allergens as defined by UK food supplement labelling regulations — including gluten and soya.
"I did three rounds of IVF before I got on the right form and dose of CoQ10. I don't want you to do the same."
-
Naturally fermented, the form your body recognises Our ubiquinone is naturally fermented not synthesised from petrochemical precursors. This process yields the all-trans isomer which is the same found in human tissue.
-
A meaningful dose, not a token amount Most multivitamins include CoQ10, but at doses too low to reflect the research. Ours is a standalone 400mg capsule taken twice daily, because dose is everything.
-
No synthetic fillers, binders or additives Just ubiquinone, a plant-based capsule shell, brown rice flour and bamboo silica, a natural plant-derived ingredient that helps ensure consistent capsule filling.
-
Made in the UK to Good Manufacturing Practice standards GMP ensures consistent quality, hygiene and traceability in every batch.
CoQ10 is one of the most researched supplements in reproductive nutrition
The natural fermentation process we use ensures a pure product in the form your body recognises. Explore the benefits for your fertility.
Eggs contain more mitochondria than almost any other cell in the body. The process of egg maturation and early embryo development is extraordinarily energy-intensive. CoQ10 is the essential electron carrier in the mitochondria that drives the production of ATP, the cell's energy currency. Adequate CoQ10 in the egg's mitochondria supports the energy supply this process depends on.
CoQ10 functions as an electron carrier within the inner mitochondrial membrane, facilitating the transfer of electrons between complexes I/II and complex III, a process central to ATP synthesis via oxidative phosphorylation. Egg cells undergo meiosis, a process of chromosomal division that is highly energy-dependent. Mitochondrial function is considered relevant to the quality of this process in reproductive biology research.
Studies in animal models have investigated the relationship between CoQ10 and mitochondrial function in oocytes. A 2015 study by Ben-Meir et al. in Aging Cell examined CoQ10 supplementation in aged mice and found associations with mitochondrial function markers in egg cells. Animal studies provide mechanistic insights, though human research is needed to draw direct conclusions.
The relationship between CoQ10 supplementation and egg cell parameters has been examined in randomised controlled trials and systematic reviews, with CoQ10 emerging as one of the most studied supplements in the context of female reproductive health. Research in this area continues to develop, and CoQ10's role in supporting mitochondrial function in egg cells is a recognised area of scientific interest.

CoQ10 plays a dual role: it is both a driver of energy production and a potent antioxidant. Inside the mitochondria, energy production generates reactive oxygen species as a byproduct. When these accumulate faster than the cell can neutralise them, they damage mitochondrial DNA, cell membranes, and the chromosomal machinery inside eggs. CoQ10 neutralises free radicals directly within the mitochondria, protecting the integrity of the egg at its most vulnerable point.
CoQ10 exists in two interconvertible forms: ubiquinone (oxidised) and ubiquinol (reduced). In its reduced form, ubiquinol acts as a lipid-soluble antioxidant, capable of scavenging free radicals within cell membranes and mitochondria. This is particularly significant in the context of reproductive ageing: oxidative stress is recognised as a key driver of age-related decline in oocyte quality, and mitochondrial reactive oxygen species production increases with age.
CoQ10 is one of the most studied antioxidant supplements in the context of female reproductive health, and its relationship to oocyte mitochondrial function has been examined in a number of clinical studies. The body's natural CoQ10 production declines from the mid-thirties, which is relevant to its antioxidant role at the point when egg cell health becomes a greater consideration.

Our CoQ10 is produced through natural fermentation rather than chemical synthesis from petrochemical precursors. The natural fermentation process yields pure ubiquinone in the all-trans isomer, the same structural form found in human tissue, and results in a cleaner product with fewer process-related impurities.
Ubiquinone can be produced via two main routes: chemical synthesis (often using tobacco-derived solanesol or petrochemical precursors) or microbial fermentation (typically using yeast or bacteria such as Rhizobium or Agrobacterium). Fermentation-derived ubiquinone produces the all-trans isomer, the form found naturally in human tissue, whereas chemical synthesis can yield cis/trans isomer mixtures with potentially lower biological activity. Fermentation also results in a higher-purity starting material, with fewer residual solvents and synthesis byproducts. Our ubiquinone is tested for identity and purity prior to encapsulation, ensuring what goes into the capsule matches what is on the label.
