Quercetin: A Vital Antioxidant for PCOS

Quercetin in berries

Quercetin—a powerful antioxidant found in red wine, berries, apples, and other common foods—has been shown to have anti-inflammatory effects on PCOS. It’s a flavonol-type antioxidant (a class of flavonoids) that exists naturally in many foods, and can also be taken in supplement form.

Quercetin is known to have a positive effect on glucose homeostasis. This is how glucagon and insulin balance to maintain blood glucose.

If you’re unfamiliar with the term “inflammatory cascade”, it’s the series of inflammation-related issues within the body found in conditions like PCOS.  Quercetin has been proposed to impact (and reduce) this cascade. 

Since inflammation is the root of so many health issues and diseases, reducing it is of major benefit on countless different levels. As an example, a recent study on women with PCOS showed that taking 1,000mg of Quercetin daily reduced these women’s LH and testosterone levels. They also had significant reductions in resistin.

Below is a list of common foods that have naturally high Quercetin levels:

Quercetin’s Anti-Inflammatory Effects

PCOS is associated with fat cell dysfunction. As such, immune cells have to clean up a lot of the damage in these tissues, and when they do, they secrete resistin. This is an important hormone made by the immune cells that surround fat cells (adipocytes).

This type of fat cell dysfunction, which is so common in PCOS, is characterized by the resistin marker. Resistin levels also increase in people with type 2 diabetes and insulin resistance.
