Quercetin and Bempedoic Acid,Ezetimibe

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ORGANIC ANION TRANSPORTER 3 (OAT3) SUBSTRATES

Why this applies to Bempedoic Acid,Ezetimibe

Bempedoic Acid,Ezetimibe falls under ORGANIC ANION TRANSPORTER 3 (OAT3) SUBSTRATES — the group Quercetin interacts with.

Theoretically, concomitant use might increase the effects and adverse effects of OAT3 substrates.

In vitro research shows that quercetin is a strong non-competitive inhibitor of OAT3, with half-maximal inhibitory concentration (IC50) values as low as 0.75 mcM. So far, this interaction has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with Nexlizet (bempedoic acid plus ezetimibe), which you take to help lower cholesterol. Your kidneys use a transporter called OAT3 to help clear bempedoic acid out of your body. Lab studies suggest quercetin can block that transporter, so in theory the drug could hang around a bit longer and build up slightly. If that happened, you might notice more of bempedoic acid's known effects, like muscle aches, or changes in uric acid that can nudge gout in people prone to it.

I want to be honest though: this is based only on test-tube research and has never actually been reported in people. Food amounts of quercetin almost certainly don't matter. If you're considering a concentrated supplement, just run it by your pharmacist or doctor first.

About Quercetin

What is Quercetin?

Quercetin
  • Seasonal allergies

  • Immune support
  • Exercise recovery

Quercetin is a plant flavonoid with antioxidant and anti-inflammatory properties found in many common foods and sold as a supplement. While early research is interesting for allergies, blood pressure, and inflammation, strong human evidence is limited for most uses. It is generally well tolerated in food amounts, but talk to your pharmacist or doctor before taking high-dose supplements.
