3 Reasons Women with PCOS Need CoQ10

CoQ10

Coenzyme Q10 – A Mitochondria Powerhouse

What is Coenzyme Q10?

Coenzyme Q10, commonly known as CoQ10, is an antioxidant which has many different functions in the body – including energy production, growth and maintenance of cells, and metabolism.  Its role as an antioxidant also benefits immunity, fatigue, heart health, and plays a crucial role in the reproductive system. CoQ10 is known as a mitochondria nutrient – your mitochondria are the energy centers inside all of your cells.

Coenzyme Q10 for Women with PCOS

There are three main reasons a woman with PCOS may consider CoQ10 supplementation, and I’ll review each of them along with the related research.

1) Metabolic and cholesterol parameters in PCOS:

In women with PCOS, CoQ10 supplementation even at a fairly low dose of 100 mg daily can have a significant beneficial impact glucose metabolism, insulin resistance and also lower LDL-cholesterol levels.

This adds to previous research showing many positive impacts of CoQ10 on cardiovascular health, including raising HDL cholesterol, lowering inflammatory biomarkers such as C-reactive protein, and reducing blood pressure to name a few.

2) Egg Quality for Fertility in PCOS:

With age, egg quality and maturation declines, along with CoQ10 utilization by the mitochondria (the “powerhouse”) of the eggs. The reduced utilization impacts energy production and results in egg damage, affecting the quality of an embryo. The use of CoQ10 in women with PCOS has proven to reduce oxidative stress and improve egg quality. Furthermore, increased concentrations of CoQ10 in the body are correlated with higher grade embryos and better embryo development in IVF. Dosing for egg quality tends to be on the higher end of the spectrum, with most sources agreeing with 600-800 mg of CoQ10 daily.

3) Ovulation and Other Fertility Markers with CoQ10 Supplementation:

Studies have shown that for individuals who are taking clomiphene citrate (Clomid) for ovulation induction in PCOS, the addition of CoQ10 supplementation significantly improves ovulation and clinical pregnancy rates. In this study, pregnancy rates were 6% with Clomid alone, to 37% using Clomid plus 180 mg of CoQ10 per day. The Coenzyme Q10 supplementation improved the number of follicles, endometrial thickness, serum estrogen and progesterone in clomid-resistant women with PCOS. Imagine the results if we also addressed nutrition, stress reduction, and increased daily activity!

Ubiquinol vs. CoQ10 supplements

There are two forms of CoQ10 – ubiquinol and ubiquinone (normally labeled as CoQ10). Our cells rely on both forms for overall health and energy production. The body actually converts CoQ10 into ubiquinol, and this conversion starts to decline later in your 30’s. For this reason, the older you are the more important it is to use ubiquinol supplements instead of simple CoQ10. The other consideration when choosing supplements is that you will need a lower dose of ubiquinol to achieve the same effect – typically half of the CoQ10 dose.

Take home messages

Coenzyme Q10 supplements (or Ubiquinol if you’re older) can play an important role in both metabolic and cardiovascular health by complementing nutrition, exercise, and lifestyle factors to lower glucose levels and reduce insulin resistance, and also protect your cardiovascular system.

It is also an important nutrient to consider for fertility, both for egg and embryo quality through supporting mitochondria function, and also to significantly improve ovulation and fertility response when used with clomiphene citrate.
