L-Carnitine For Women With PCOS – Does It Help?

Carnitine is a group of related compounds naturally produced by the human body that have a role in energy production, metabolism and other vital cellular functions particularly related to the mitochodria.

In my recent piece on supplements for hypothyroidism, I referenced an experimental study demonstrating that L-Carnitine (one form of supplemental carnitine) may reduce fatigue in those living with hypothyroidism.

Soon after writing it, I came to realize that L-carnitine also been studied in the context of PCOS, a topic which I’ve also written about on a few occasions recently.

With that in mind, the goal of today’s article is to close the loop.

Let’s get right to it.

L-Carnitine And PCOS

It’s possible but not definite that women living with PCOS may have lower circulating carnitine levels than woman who are not.

This finding creates a natural curiosity around the role of carnitine supplementation in PCOS but doesn’t guarantee it will actually help.

Here are some recent findings to consider:

A 2021 study out of the Advances In Therapy journal found that supplementation with a specific type of L-carnitine ( acetyl-L carnitine or ALC) provided additional benefits to women with PCOS who were already being treated with metformin and pioglitazone.

A 2019 study out of the Journal Of Obstetrics & Gynecology found that women living with PCOS who took L-carnitine in conjuction with letrozole had improved ovulation rates.

The above are a sample of more recently published studies looking at L-carnitine supplementation in very specific sub-contexts of PCOS, if you’d like to take a closer look at some of the other research done on this supplement I encourage you to head over to page 4 of “Role Of L-Carnitine in female infertility” published in Reproductive Biology And Endocrinology.
