Citrus Bergamot: Uses, Benefits, Dosage & Safety
Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
Quick summary
Citrus bergamot is a citrus extract studied for cholesterol and blood sugar. Some trials show modest improvements in lipids, but the evidence base is still developing and quality varies.
What is Citrus Bergamot?
Citrus bergamot (Citrus bergamia) is a fragrant citrus fruit grown mainly in southern Italy, best known for flavouring Earl Grey tea. Its juice and peel are rich in distinctive polyphenols (flavonoids). As a supplement, standardised bergamot extract is marketed mainly for cholesterol and cardiometabolic health, sometimes as a 'natural' alternative for people who want to support their lipids.
What Citrus Bergamot is commonly used for
Citrus Bergamot is used in supplements as nutritional support, not as a treatment for any medical condition.
How Citrus Bergamot works
Bergamot's polyphenols are thought to influence cholesterol production and metabolism in the liver (acting, in part, on similar pathways to statins but far more weakly) and to have antioxidant effects. These mechanisms are the rationale for its cholesterol and blood-sugar marketing, though the human evidence is still maturing.
What the evidence says
Here's an honest snapshot of what published research suggests about Citrus Bergamot — including where the evidence is limited.
- Several trials suggest standardised citrus bergamot extract may modestly reduce LDL cholesterol and triglycerides and raise HDL. (PubMed research)
- Some studies report effects on blood sugar and metabolic markers, with preliminary results. (PubMed research)
- Trial sizes and extract standardisation vary, so conclusions remain tentative. (PubMed research)
Typical dosage used in studies
Studies have used roughly 500-1,000 mg/day of a standardised bergamot polyphenol extract. This is research information, not a recommendation.
Side effects and safety
Citrus bergamot is generally well tolerated; mild digestive upset or heartburn are the most commonly reported effects.
Medication interactions and who should avoid Citrus Bergamot
Medication & safety check
People on cholesterol or blood-sugar medication should coordinate with a doctor because of possible additive effects, and high cholesterol should be managed medically rather than self-treated. Pregnancy and breastfeeding data are limited. As with grapefruit, be mindful of potential interactions with drugs metabolised by the liver.
This is general information, not personal medical advice. If you take any medication, confirm it's safe to combine with Citrus Bergamot with your doctor or pharmacist first.

Frequently asked questions
Does citrus bergamot lower cholesterol?
Some trials suggest a modest reduction in LDL and triglycerides, but the evidence is still developing and extracts vary.
Is it like a natural statin?
It acts far more weakly on some similar pathways, but it is not a statin and shouldn't be treated as a substitute for prescribed cholesterol treatment.
What dose is used?
Around 500-1,000 mg/day of a standardised polyphenol extract in studies.
Is citrus bergamot safe?
Generally well tolerated, with mild digestive effects the main complaint.
Should I use it instead of my cholesterol medication?
No — manage cholesterol with your doctor. It may be a modest add-on at most, not a replacement.
