Coenzyme Q10 supplement: a studied ally for preconception

Coenzyme Q10, also known as ubiquinone, is a molecule your body produces naturally and which is found in every cell. It is involved in cellular energy production at the heart of the mitochondria and has antioxidant properties. Its synthesis by the body tends to decrease with age, and diet alone (primarily meat, offal and oily fish) provides only modest amounts. A coenzyme Q10 dietary supplement therefore allows for a more regular and better-dosed intake, which explains the growing interest in this molecule during the preconception period.

In this collection, you will find Ovo+, our female fertility formula combining 300 mg of coenzyme Q10 (in ubiquinone form) with N-acetyl-cysteine, L-tryptophan and zinc bisglycinate. It is a vegan formula, manufactured in France, designed to support the preconception phase over several weeks. The form and quality matter as much as the dosage: an active ingredient at the right dose in a traceable formula is the starting point for a coherent course of supplementation.

Coenzyme Q10 is the subject of research in relation to fertility, particularly around oocyte quality and the energy of reproductive cells, but no health claim is currently authorised on this subject, and a supplement does not replace medical follow-up. If you are preparing for the arrival of a baby, Q10 is part of a broader approach: find our other guidance in the fertility collection, our formulas dedicated to the pregnancy period, and to go further on the subject, our article on coenzyme Q10 and fertility.

Key takeaway: coenzyme Q10 is an antioxidant that the body produces less of with age. As a supplement, it provides regular, measured support that has been studied in the context of preconception.

FAQ - How to choose and use your coenzyme Q10 supplement

A coenzyme Q10 supplement provides, in capsule form, a molecule called ubiquinone, which the body already produces naturally. It is involved in energy production within cells and plays an antioxidant role. Supplementation is most relevant when dietary intake is limited or when natural synthesis declines with age. At Jolly Mama, Q10 is included in Ovo+, our formula designed for the preconception phase for women, and in Cocooning+ Men for men. 

The doses used in studies range from 200mg to 600mg per day, which is why the dose selected in Ovo+ is 300mg per day (2 capsules). There is no official reference intake for coenzyme Q10, as the body produces it naturally. The best guide remains a clear, traceable formula suited to your individual situation. For personalised advice, consult your midwife or doctor.

Coenzyme Q10 exists in two forms: ubiquinone, the oxidised form most commonly found in supplements, and ubiquinol, its reduced form. The two are interlinked in the body, which converts between them according to its needs. Ovo+ uses ubiquinone, a stable and well-documented form. The key is to choose a formula with transparent origins and composition.

Ovo+ is designed for the preconception phase, that is, before pregnancy, to support the baby journey. Once pregnancy is confirmed, nutritional needs change and other formulas are more suitable, such as our supplements from the pregnancy collection. Each stage of motherhood has its own nutritional priorities, and it is better to adjust your course of supplements rather than continuing with the same one out of habit.

Coenzyme Q10 is generally well tolerated at the usual dosages used in food supplements. As with any supplement, a small number of people may experience mild digestive discomfort, which is often reduced by taking the capsules with a meal. If you are undergoing treatment, check the precautions indicated on the product information sheet before combining it with a supplement.

Coenzyme Q10 is found mainly in animal-derived products: meats, offal such as liver and heart, and oily fish. Vegetable oils and certain nuts and seeds provide more modest amounts. Diet can therefore contribute to covering part of the body's needs, but the quantities obtained remain limited, which explains the value of a supplement when a more regular intake is desired.

Coenzyme Q10 contributes to cellular energy production, which is why it is often cited in relation to vitality. That said, no health claim is officially authorised on this point, and Q10 does not replace sleep or a balanced diet. If you are going through a period of fatigue, several approaches exist, which you can explore in our collection fatigue and lack of energy.

Benefits of our products for Coenzyme Q10 supplement: a studied ally for preconception

Understanding coenzyme Q10 and its value as a supplement

The role of coenzyme Q10 in the body

Coenzyme Q10 concentrates in the mitochondria, those small structures that convert nutrients into energy usable by the cell. It is involved in the respiratory chain and thus contributes to cellular energy production that every organ needs to function. Q10 also acts as an antioxidant, helping to protect cells against oxidative stress. This dual function — energetic and protective — explains why this molecule is studied in many contexts, including preconception and the quality of reproductive cells.

Coenzyme Q10 and diet: why a supplement?

The body produces its own coenzyme Q10, but this synthesis gradually decreases with age. Diet complements this intake, mainly through animal products. However, the quantities provided remain modest compared to the dosages used in preconception supplements, which justifies the interest in a course of supplementation when seeking a more regular and controlled intake.

Did you know: nearly 95 per cent of the body's energy needs are processed with the help of coenzyme Q10, making it a central molecule in cellular metabolism.

Coenzyme Q10 and preconception: what the research says

Coenzyme Q10 is the subject of research related to fertility, particularly around oocyte maturation and quality. The hypothesis under study rests on its role in mitochondrial energy and its antioxidant function — two important factors for reproductive cells. It is this angle that guided the formulation of Ovo+, where Q10 is combined with other preconception actives. It remains important to bear in mind that no health claim is authorised on this subject and that a supplement supports a process without replacing medical supervision. For those going through a period of hormonal transition, other reference points can be found in our collections. menopause and cycle.

If you are currently on medication, have a medical history, or are already pregnant, pay close attention to the composition of your formula and refer to the precautions indicated on the product sheet before starting a course. A coenzyme Q10 supplement is part of an overall healthy lifestyle and does not replace a varied diet or medical support.
