How Much CoQ10 Should You Take for Fertility?

If you’ve started researching fertility supplements, you’ve probably come across CoQ10. It’s often recommended for women trying to conceive, especially those considering egg freezing or IVF. But how much CoQ10 do you actually need—and when should you start taking it?

At fertie, we believe that understanding your options (without the overwhelm) helps you feel more in control of your fertility journey. Let’s break down what CoQ10 does, how it can help, and the dosage experts typically recommend.

What Is CoQ10 and Why Is It Important for Fertility?

Coenzyme Q10 (CoQ10) is a powerful antioxidant found in every cell of your body. It plays a key role in energy production at the cellular level—specifically in the mitochondria, the energy powerhouse of your cells.

When it comes to fertility, CoQ10 has been shown to support egg quality by improving mitochondrial function. As we age, our bodies naturally produce less CoQ10, which can impact the health and energy of our eggs.

If you’re over 35 or have a diminished ovarian reserve (DOR), your doctor may suggest CoQ10 as part of your fertility preparation plan.

How Does CoQ10 Support Egg Quality?

Your eggs rely on mitochondria to provide the energy needed for maturation, fertilization, and early embryo development. Poor mitochondrial function is linked to lower egg quality, which can affect both natural conception and IVF success rates.

CoQ10 helps by:

• Supporting energy production within the eggs

• Acting as an antioxidant, reducing oxidative stress that can damage egg cells

• Potentially improving fertilization and embryo quality in IVF cycles

How Much CoQ10 Should You Take for Fertility?

General Recommended Dosage

Most fertility specialists recommend 200mg to 600mg of CoQ10 per day.

• If you’re in your early 30s with no known fertility issues, a lower dose (200mg daily) may be appropriate.

• If you’re 35 or older, or have low AMH / diminished ovarian reserve, your doctor might suggest a higher dose, typically 400mg to 600mg daily.

Which Form Is Best?

Look for Ubiquinol, the active and more easily absorbed form of CoQ10.

• Ubiquinol has better bioavailability, meaning your body can use it more efficiently compared to the standard ubiquinone form.

When Should You Start Taking CoQ10?

Egg development happens over a 90-day cycle before ovulation. This means it’s ideal to start taking CoQ10 at least 3 months before you plan to conceive, freeze your eggs, or start IVF.

• Starting early gives your body time to build up CoQ10 levels and support the eggs that are developing for future ovulation or retrieval.

Is CoQ10 Safe to Take During Pregnancy?

Most doctors recommend stopping CoQ10 once pregnancy is confirmed, unless advised otherwise by your healthcare provider. While some studies suggest CoQ10 may have benefits during early pregnancy, always consult your doctor before continuing any supplements.

Final Thoughts

CoQ10 may support egg health—especially for women over 35 or those preparing for IVF or egg freezing. While it’s not a magic pill, research suggests it can help improve mitochondrial function and reduce oxidative stress, which may benefit egg quality.

As with any supplement, timing and dosage matter—and it’s always best to check with your doctor before starting.
