Preparing for Egg Freezing: A Guide to the Supplements That Actually Matter

The Importance of Egg Health Before Egg Freezing

If you’re getting ready for egg freezing, it’s normal to start thinking about how to get the best outcome. Specifically, what you can do in the weeks leading up to your cycle to support your body.

One of the most common questions we hear is, “Should I be taking supplements before egg freezing? If so, what?”

The truth is, there is evidence that some supplements can help nurture the environment in which your eggs develop. This is usually centered around fueling cellular energy and managing oxidative stress. But it is important to be clear: supplements can’t “turn back the clock,” and they can’t guarantee a certain number of eggs. 

It’s also important to note that supplements are part of a larger picture and are not one-size-fits-all. Supplements are just that — meant to supplement the vitamins, minerals, antioxidants, and other nutrients that your body lacks in order to function its best. 

Understanding Egg Quality & Quantity

People often talk about egg health in two buckets: quantity and quality.

Egg quantity is your ovarian reserve—an estimate of how many eggs you have left. Tests like AMH (a blood test) and antral follicle count (an ultrasound) help your clinic understand how your ovaries might respond to stimulation.

Egg quality is about how likely an egg is to fertilize and develop normally. Quality is influenced more by age than by anything else. However, quality also reflects what’s happening inside the egg at a cellular level. This includes how well the egg’s mitochondria (its “energy producers”) are functioning and how much oxidative stress the egg is exposed to as it matures.

This is where certain supplements—especially antioxidants—come into the conversation.

Supplements to Improve Egg Quality

If you’re searching for egg quality supplements or vitamins to help egg quality, you’ll see a lot of bold promises online. We’re going to keep this grounded in what the research actually suggests.

Targeted Egg Health Support: CoQ10

CoQ10 (short for coenzyme Q10) is one of the most researched supplements for egg freezing preparation. It plays two roles that matter for eggs: supporting mitochondrial energy production and acting as an antioxidant.

CoQ10 levels naturally decline with age, and egg cells are especially dependent on mitochondria to power the complex process of cell division.

Research has shown promising results. A randomized controlled trial found that young women with poor ovarian reserve who took CoQ10 before their cycle had more retrieved eggs and better fertilization rates than those who didn’t. A broader 2025 review of the evidence also concluded that CoQ10 can enhance ovarian function and improve embryo quality, particularly for those with diminished reserve.

If you’re looking into CoQ10 and egg quality, this is why it’s so frequently recommended.

A practical note: CoQ10 comes in different forms. Ubiquinone is the standard form. 

Foundational Support: A High-Quality Prenatal-Style Supplement

If you want one baseline supplement to consider, it’s usually a prenatal-style multivitamin.

This isn’t because you’re trying to get pregnant right now. It’s because egg development relies on nutrients involved in DNA synthesis. Folate (the active form of folic acid) is the best-known example. Adequate folate is essential for the proper replication of genetic material during egg maturation.

When people search for prenatal vitamins for egg freezing, they are often looking for a simple, safe place to start. For many, a high-quality prenatal is that starting point.

Supplements to Improve Egg Quantity

It’s important to remember that supplements cannot create new eggs. Everyone is born with a finite number of eggs, and that number declines over time. However, in specific medical scenarios, certain supplements are used to support the hormonal environment.

DHEA (only with medical guidance and a prescription)

DHEA is a hormone precursor. In fertility care, it is sometimes used for patients with diminished ovarian reserve.

A systematic review and meta-analysis found that DHEA supplementation was associated with a significant increase in pregnancy likelihood and a reduction in miscarriage rates for women with poor ovarian response undergoing IVF.

Because DHEA is a hormone and requires a prescription in Canada, it is not a DIY supplement. It can have side effects like acne or mood changes, and it should only be taken if your fertility specialist specifically recommends it after testing your levels.

Additional Supplements for Overall Fertility & Health

You may also hear about vitamin D or Omega-3s.

The most accurate way to think about these is as gap fillers. For example, many Canadians are vitamin D-deficient, especially in the winter. Since low vitamin D levels have been associated with lower ovarian reserve in some studies, correcting a deficiency is a reasonable step. However, too much vitamin D can be harmful to people with normal vitamin D levels. 

Getting your levels tested and knowing your baseline is important. 

Recommendations from a Fertility Clinic

The supplement world is noisy. A simple, clinic-style approach usually looks like this: start with a prenatal foundation, then add targeted support to support your unique biology and needs. 

EVOLVE’s Choice: Bird&Be Power Prenatal Pack

At EVOLVE, we often suggest the Bird & Be Power Prenatal Pack. It uses a hybrid of folate (including both folic acid and methylfolate) to provide comprehensive support for egg freezing prep. 

Bird&Be CoQ10 Boost

If CoQ10 is part of your plan, an add-on like Bird & Be’s CoQ10 is a straightforward way to include it. Your specific dose should always be confirmed with your care team.

When Should You Start Supplements Before Egg Freezing?

Timing matters because eggs develop in waves. It takes roughly 100 days for an egg to reach the final stage of maturation.

This is why we generally suggest starting your supplement routine about 3 months before your retrieval. If your cycle is sooner than that, don’t worry—starting now is still better than not starting at all.

A Note on Expectations

Supplements can support, but they cannot promise.

They don’t replace age, and they don’t override your natural ovarian reserve. What they can do is help you feel confident that you’ve supported your cellular health in a measured, evidence-informed way.

At EVOLVE, we use the VIOLET™ egg quality report to give you individualized insight into the quality of the eggs you freeze. This moves the conversation away from “averages” and toward your specific results.
