Citrus Bergamot
Clinically Informed Overview
Last reviewed: May 2026
Citrus Bergamot at a Glance
What It Is
A polyphenol-rich extract derived from Citrus bergamia, a citrus fruit native to Southern Italy. Standardized extracts contain flavonoids such as neoeriocitrin, naringin, and neohesperidin.
Main Benefit
Research suggests citrus bergamot may support healthy cholesterol and triglyceride levels within normal ranges and may be associated with effects on lipid metabolism pathways.
What to Expect
Most clinical studies use standardized bergamot polyphenolic fraction (BPF) at 500–1000 mg daily. Effects on lipid biomarkers are typically evaluated over 8–12 weeks.
Medication Caution
May interact with lipid-lowering or glucose-lowering medications.
The Verus Standard
Verus PhytoMed™ prioritizes standardized bergamot polyphenolic fraction (BPF), the form most commonly used in clinical research. This supports alignment with the current body of evidence and provides a more consistent flavonoid profile compared to non-standardized extracts.

What Is Citrus Bergamot?
Citrus bergamot (Citrus bergamia) is a citrus fruit primarily cultivated in Calabria, Italy. The extract used in supplements is typically derived from the fruit and standardized to a defined polyphenol content.
Key active compounds include:
Neoeriocitrin
Naringin
Neohesperidin
These flavonoids are believed to contribute to its metabolic and cardiovascular effects.
How Citrus Bergamot Works
Citrus bergamot has been studied for its potential effects on pathways involved in lipid and metabolic regulation.
Proposed mechanisms include:
Modulation of pathways involved in cholesterol synthesis, including those related to HMG-CoA reductase activity
Changes in LDL receptor expression associated with lipid metabolism
Antioxidant activity observed in experimental and clinical settings
Potential activation of AMPK-related metabolic pathways
Influence on lipid transport and triglyceride metabolism pathways
These mechanisms are biologically plausible but continue to be studied.
What the Research Shows
While individual studies vary, several patterns appear across randomized trials and systematic reviews.
Cardiovascular and Lipid Support
Across randomized trials and meta-analyses, citrus bergamot has been studied in relation to: (Refs. 1-5)
Healthy LDL cholesterol levels
Healthy triglyceride levels
Healthy total cholesterol
Support for HDL cholesterol
Research Summary: Across multiple meta-analyses and systematic reviews of randomized controlled trials, citrus bergamot supplementation has been associated with reductions in LDL cholesterol of approximately 15–30 mg/dL, triglyceride reductions of approximately 10–30 mg/dL, and modest improvements in HDL cholesterol under study conditions. Reported effects vary based on extract standardization, baseline lipid status, dose, and study duration. (1-5)
Metabolic Support
Emerging research suggests citrus bergamot may be associated with effects on: (Ref. 6)
Healthy glucose metabolism
Insulin sensitivity
Metabolic health biomarkers
Liver and Oxidative Stress
Preliminary studies suggest potential associations with changes in: (Ref. 7)
Liver enzyme balance
Oxidative stress markers
Quality and Standardization
High-quality citrus bergamot supplements typically include:
Standardized bergamot polyphenolic fraction (BPF)
Transparent flavonoid content
Transparent sourcing and manufacturing
Third-party testing for purity and contaminants
Verus PhytoMed™ emphasizes quality control and contaminant screening to support consistent formulation standards.
Typical Research Dosing
In clinical research settings, citrus bergamot has most commonly been evaluated at the following dose ranges:
500–1000 mg daily of standardized BPF extract
These dosing ranges reflect research protocols used in clinical studies. Individual needs may vary.
Consult a qualified healthcare professional before using any dietary supplement.
Safety and Tolerability
Citrus bergamot has been generally well tolerated in clinical studies.
Reported side effects may include:
Mild gastrointestinal discomfort
Safety Considerations
May interact with cholesterol or glucose-lowering medications
Use is generally not recommended during pregnancy or breastfeeding due to limited safety data
Evidence Context
Citrus bergamot has been evaluated in multiple randomized trials and meta-analyses.
When reviewing the research, several limitations should be considered. Many studies:
Have short study durations (often 8–12 weeks)
Involve small to moderate sample sizes
Focus on laboratory biomarkers rather than long-term outcomes
Larger and longer-term studies are still needed to better understand long-term outcomes. Because dietary supplements are studied in a wide range of populations and study designs, results from individual studies may not apply to every individual.
Summary
Citrus bergamot is a polyphenol-rich botanical with growing clinical evidence suggesting potential roles in lipid and metabolic health. When standardized and used appropriately, it represents a scientifically grounded option within evidence-informed wellness strategies.
