Can CoQ10 Supplements Really Help With Your Fertility?

For both men and women, there’s some research that CoQ10 may improve fertility. Of course, many factors can influence fertility from age and genes to your weight and lifestyle habits (like smoking, drinking, and drug usage) so take everything with a grain of salt as no one supplement is a magic fertility solution.

For men: As Dr. Crawford explains, men produce sperm every single day. Many factors influence sperm concentration, motility, and quality, and the antioxidant properties of CoQ10 may help prevent DNA damage inside the sperm, she says. It can improve sperm quality by reducing oxidative stress and increasing energy production in sperm cells.

For sperm quality, a typical recommended dosage is around 200 to 300 mg per day.

For women: “Since women are born with all their eggs inside their ovaries, the mitochondria inside each egg are also susceptible to damage associated with age,” says Dr. Crawford. “The mitochondria inside the eggs play a vital role in cell division and help the eggs have a normal chromosome number as they mature.”

Godfrey notes that CoQ10 may help enhance egg quality, particularly in older women or those with diminished ovarian reserve; there’s also some research suggesting higher follicular fluid CoQ10 levels are linked to higher pregnancy rates.

Studies often recommend doses ranging from 100 to 600 mg per day, with some suggesting higher doses for those undergoing fertility treatments. It’s worth noting that most clinical trials which have evaluated CoQ10 for egg quality have studied supplementation with 400–600 mg a day. So if you’re taking CoQ10 specifically for fertility benefits, you may want to talk to your doctor about the proper dosage.
