Bergamot and Liraglutide

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

Moderate

ANTIDIABETES DRUGS

Why this applies to Liraglutide

Liraglutide falls under ANTIDIABETES DRUGS — the group Bergamot interacts with.

Theoretically, taking bergamot with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research suggests that bergamot juice has hypoglycemic effects.
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 simple version: liraglutide (Victoza) already lowers your blood sugar, and bergamot supplements may nudge your sugar down a little too. Put them together and the worry is that your blood sugar could dip too low. With a glucose-lowering drug like liraglutide, a hypoglycemic episode can show up as shakiness, sweating, dizziness, a fast heartbeat, or feeling confused.

I want to be honest about how strong this is, though. The concern is theoretical, based mostly on animal studies of bergamot juice, not solid human data. It's not a reason to panic. If you're considering a bergamot supplement (often used for cholesterol), just loop in your pharmacist or doctor first and keep an eye on your home glucose readings when you start.

See Every Supplement That Interacts With Liraglutide

From our pharmacist’s overview on the Liraglutide page

“If you take liraglutide (Victoza), the ingredient to know first is Siberian cocklebur, the only major-rated interaction of the 239 on this page. Its seeds have caused severe hypoglycemia in people, dangerously low blood sugar, and liraglutide already pushes glucose down.”

About Bergamot

What is Bergamot?

Bergamot
  • High cholesterol
  • Heart and metabolic health
  • Anxiety and stress (aromatherapy)
  • Antimicrobial/antiseptic
  • Skin care and fragrance

Bergamot is a Mediterranean citrus fruit, and its standardized extract is most often used to support cholesterol and heart health, with some early but promising research. The essential oil is widely used for fragrance and aromatherapy but should not be taken by mouth, and it can make skin more sensitive to sunlight. Talk with your pharmacist or doctor before using bergamot supplements, especially if you take medicine for cholesterol or blood sugar.
