Pregnancy cannot be guaranteed with a dietary supplement. However, many studies show that the right nutrients can play an important role in how eggs mature, fertilize, and develop further. Particularly important are a good base with multivitamins and folate, CoQ10 (preferably as ubiquinol), omega-3 fatty acids, vitamin D, and – in some cases – probiotics, myo-inositol, and melatonin.
Fay Hepper is a fertility-focused brand that builds its range around these areas: fertility multivitamin, ubiquinol, highly concentrated omega-3, and probiotics linked to gut and microbiome health.
What does egg quality actually mean?
Egg quality refers to the egg's ability to:
-
undergo maturation
-
fertilize
-
to share further
-
develops into a healthy embryo with the correct chromosome set.
Mitochondria (the “powerhouse” of cells), energy production, hormones and protection against oxidative stress play a central role here. Egg quality is strongly influenced by age, but also by nutritional status, lifestyle, environmental factors and underlying health.
Supplements cannot create new eggs, but they can give existing eggs better conditions by:
-
support mitochondria
-
strengthen the body's antioxidant defenses
-
contribute to a balanced hormonal environment
-
affect inflammation, blood lipids and blood flow.
It is this logic that lies behind many of the supplements highlighted in the book It Starts with the Egg and in modern fertility research.
Which dietary supplements have the strongest link to egg quality?
When looking at the research as a whole, the following groups in particular recur:
-
multivitamin with folic acid
-
CoQ10 in the form of ubiquinol
-
omega-3 (with both EPA and DHA)
-
Vitamin D
-
probiotics and microbiome focus
-
myo-inositol (especially in PCOS)
-
melatonin in some IVF setups.
They are often used in combination with lifestyle changes and fertility treatment, with many clinics placing great emphasis on dietary supplements in the months before egg retrieval or pregnancy attempts.
How can multivitamins and folic acid support egg quality?
Folic acid and B vitamins are essential for DNA synthesis, cell division and hormone metabolism. Large studies have shown that women who take multivitamins with folate have a lower risk of some forms of ovulation-related infertility, suggesting that a good micronutrient status makes a difference.
A fertility-friendly multivitamin:
-
ensures sufficient folic acid intake before pregnancy
-
replenishes important vitamins and minerals that are often low in women undergoing fertility testing
-
reduces the risk that deficiencies in the “basic nutrients” limit the effect of other supplements or treatments.
Folate has long been a standard recommendation for pregnancy, and in the fertility world, a good multivitamin serves as the foundation of almost every protocol.
How does CoQ10 (ubiquinol) affect egg quality?
CoQ10 is a key component of mitochondria, where it is needed for energy production and as an antioxidant. In several studies of women with reduced egg reserve or poor response to IVF, CoQ10 as pretreatment has led to:
-
more developed follicles
-
more mature eggs (MII oocytes)
-
better embryo quality
-
in some studies also higher pregnancy rates.
So it's not just about "some isolated study", but about a growing body of research that points in the same direction: CoQ10 is one of the most interesting supplements for women with reduced egg reserves or older age.
Ubiquinol is the reduced, more bioavailable form of CoQ10. Many premium brands, including Fay Hepper, choose ubiquinol precisely to ensure that as much of the CoQ10 as possible reaches the cells where it is needed most.
Can omega-3 fatty acids improve the condition of eggs?
The omega-3 fatty acids EPA and DHA are building blocks of cell membranes and affect inflammation, blood lipids and blood flow. Studies on women undergoing assisted reproduction have shown that a higher intake of omega-3 may be associated with:
-
better oocyte quality
-
more favorable embryo development
-
improved laboratory results and in some cases better IVF outcomes.
Omega-3:
-
contributes to smooth, well-functioning cell membranes
-
balances inflammatory processes that can otherwise interfere with fertility
-
affects circulation, which is important for blood flow to the ovaries and uterine lining.
Since many people consume too little fatty fish, a concentrated omega-3 supplement is a practical way to reach levels similar to those in the studies.
What role does vitamin D play?
Vitamin D is more than just a “bone vitamin.” It is involved in immune function, hormone balance, and cell maturation. Fertility studies often show that:
-
Women with good vitamin D status have better results with IVF than women with a pronounced deficiency
-
Vitamin D deficiency is more common among women with PCOS and other hormonal imbalances.
Here is a common setup:
-
take a blood test to check your vitamin D status
-
add a customized vitamin D supplement in case of deficiency
-
Combine with other fertility supplements for the best overall support.
Vitamin D thus functions as an important piece of the puzzle in the background, and it is well established that you should avoid deficiency when trying to get pregnant.
Can probiotics and the microbiome affect fertility?
In recent years, research into intestinal and vaginal flora has gained momentum. Among other things, it is seen that:
-
a Lactobacillus-dominated vaginal flora is associated with better pregnancy outcomes, especially with IVF
-
Disturbed flora (e.g. bacterial vaginosis) can impair the possibility of implantation and increase the risk of early miscarriage
-
The gut flora affects hormones, inflammation levels and nutrient absorption – all things that are relevant to fertility.
Probiotics are not an "instant egg pill", but can be an important component for:
-
better intestinal health and nutrient absorption
-
support for the immune system and inflammation balance
-
more favorable vaginal flora in women who have had recurring problems.
Fay Hepper's probiotics are focused on gut and microbiome health as a basic support in a fertility plan.
Myo-inositol, melatonin and other complementary supplements
In addition to the basics (multivitamin, CoQ10, omega-3, vitamin D, probiotics), there are supplements that are used more selectively.
Myo-inositol:
-
is particularly well studied in PCOS
-
may improve insulin resistance and hormone balance
-
increases the likelihood of spontaneous ovulation in many with PCOS
-
often used in combination with other treatment to support both egg quality and regular cycles.
Melatonin:
-
acts as an antioxidant in the follicles
-
has been linked to better oocyte and embryo quality in several IVF studies
-
used primarily during medical follow-up in IVF protocols.
Other more hormone-like supplements, such as DHEA, should only be taken in consultation with a fertility specialist.
How do Fay Hepper's products relate to this research?
Fay Hepper has chosen to focus on the supplements where combined research and clinical experience most clearly point to benefits in fertility support:
-
Multivitamin for fertility – the base with folate, B vitamins and other micronutrients needed for egg maturation, hormones and early pregnancy.
-
Ubiquinol (CoQ10) – for mitochondria, energy production and antioxidant protection in the ovaries, especially relevant in cases of reduced egg reserve or age 30+.
-
Highly concentrated omega-3 – for cell membranes, blood fats, inflammation balance and good circulation to the reproductive organs.
-
Probiotics – for gut and microbiome health, which in turn affects hormonal balance, immune system and nutrient absorption.
As a brand, Fay Hepper clearly positions itself within fertility, egg and sperm quality and IVF preparation, with a focus on:
-
ingredients that are supported by research
-
doses in line with studies and guidelines
-
clean, EU-made products.

FAQ: Frequently asked questions about supplements and egg quality
How big a role do dietary supplements play compared to age?
Age is the single most important factor in egg quality. But within the context of your age, nutritional supplements and lifestyle can affect how well your eggs utilize their remaining potential. Many women see better lab results (more mature eggs, better embryos) when they combine treatment with a well-thought-out supplementation plan.
How long should you take supplements for egg quality?
The egg maturation process takes about three months, so at least three months of preparation is an important limit to really be able to influence the eggs that will soon be retrieved or fertilized. At the same time, both research and clinical experience show that the longer the body is supported by good nutrition, lifestyle and nutritional supplements, the better the conditions for the eggs over time.
A realistic range is to aim for 6–12 months whenever possible, especially if you know your egg reserve is low, have PCOS, or are planning IVF. This will allow multiple batches of eggs to complete their maturation journey under more optimal conditions. If the timeframe is shorter, it is still worth getting started – but at least three months is a clear minimum to aim for.
Do you have to take all the supplements at the same time?
No. For many, starting with a strong base: fertility multivitamin, omega-3, ubiquinol, and possibly probiotics is enough. Myo-inositol, melatonin, and other more specialized supplements can be added if there are specific reasons, often in consultation with the clinic.
Are supplements “incredibly important” for anyone trying to get pregnant?
Some people get pregnant without any supplements. But for many – especially those over 30, those with low egg reserves, PCOS or IVF plans – supplements are a key part of the strategy to optimize your chances. They are not a substitute for medical treatment, but can enhance your body’s own capacity.
Can you overdose on vitamins and minerals?
Yes, certain nutrients can be problematic in high doses. Therefore, it is important to choose products with well-considered doses, follow the recommended daily dose, and consult your healthcare provider if you are combining multiple products or have a medical condition.
Is there any difference between “regular” CoQ10 and ubiquinol?
Yes. Ubiquinol is the reduced, more easily absorbed form of CoQ10. For those who want to influence mitochondria and egg quality, it may be an advantage to choose ubiquinol, especially at an older age or if you are taking several different supplements at the same time.
When should you consult a doctor before starting dietary supplements?
Always if you are taking any medications (especially blood thinners, thyroid medication, hormones), autoimmune diseases, liver or kidney problems, and if you are undergoing IVF or other advanced treatments. It is also wise to involve your healthcare provider if you are planning to take many supplements at the same time.
