Bergamot (Citrus Bergamia) Extract

Antioxidant ·Emerging evidence ·Reviewed May 2026

Bergamot extract is a Citrus bergamia polyphenol preparation studied for LDL cholesterol, triglycerides, and metabolic markers. Human evidence suggests lipid-lowering effects, but many trials are small, product-specific, and not substitutes for statins or other indicated therapies. Safety review is important for people taking lipid drugs, diabetes medications, or products with possible furocoumarins.

What it's good for
  • May lower LDL cholesterol and total cholesterol1,2
  • May lower triglycerides in some studies1,3
  • May modestly support HDL and metabolic markers1,3
  • Provides citrus polyphenol antioxidant activity1,3
What to watch for
  • GI upset, nausea, or heartburn
  • Headache or dizziness
  • Possible blood glucose lowering in susceptible users
  • Pregnancy and breastfeeding due to insufficient supplement safety data
  • Use with statins, fibrates, or other lipid-lowering drugs without clinician guidance1,3

The bottom line

Evidence rating emerging. Most-documented uses: may lower ldl cholesterol and total cholesterol, may lower triglycerides in some studies, may modestly support hdl and metabolic markers. 3 sources indexed (2011–2024), with 3 interaction records on file.

The science

How it works, mechanistically.

Core mechanism

Bergamot polyphenols such as neoeriocitrin, naringin, neohesperidin, brutieridin, and melitidin may reduce hepatic cholesterol synthesis, improve LDL receptor activity, and influence AMPK and oxidative-stress pathways. Some constituents have been described as statin-like HMG-CoA reductase modulators in preclinical models, though potency varies by extract. Standardized low-furocoumarin extracts are preferred when medication interactions are a concern.3,1

Class
Citrus polyphenol lipid-support extract
Found in food
Bergamot citrus peel and juice, Earl Grey tea contains bergamot flavoring but not clinical extract doses
Low-status signs
None - bergamot extract is not an essential nutrient and has no deficiency state
Absorption
Water-soluble; take with food
Dosing

Dosing & protocol.

Common range
500-1,000 mg/day standardized bergamot polyphenol fraction, often divided with meals
Recommended form
Standardized bergamot polyphenol fraction with low-furocoumarin testing when available

Take with meals for tolerability and lipid-metabolism context. Avoid uncharacterized citrus extracts if taking drugs with grapefruit-like interaction concerns.

Goals

Goal-based dosing.

LDL Cholesterol Support

Dose: 500-1,000 mg daily1,2

Timing: With meals

Recheck lipids after 8-12 weeks and do not delay indicated prescription therapy.

Triglyceride Support

Dose: 500-1,000 mg daily1

Timing: With the largest meal

Best paired with reduced refined carbohydrate/alcohol intake and weight management when relevant.

Metabolic Syndrome Support

Dose: 500 mg twice daily3

Timing: With meals

Monitor glucose if also using glucose-lowering supplements or medications.

Lab work

Cholesterol and Lipid Support Protocol

Heart HealthOptionalModerate evidenceIntermediate$40-70/mo
Dose here
500-1000 mg per day of standardized polyphenol fraction
Timing
Once or twice daily with food

Bergamot polyphenols inhibit HMG-CoA reductase activity and pancreatic cholesterol absorption, lowering LDL and triglycerides while modestly raising HDL in clinical trials. It adds an enzyme-level mechanism distinct from the other ingredients.3,1

Safety

Full safety detail.

Side effects

  • GI upset, nausea, or heartburn
  • Headache or dizziness
  • Possible blood glucose lowering in susceptible users
  • Possible interaction risk with lipid or CYP3A4-sensitive medications depending on extract composition

Contraindications

  • Pregnancy and breastfeeding due to insufficient supplement safety data
  • Use with statins, fibrates, or other lipid-lowering drugs without clinician guidance1,3
  • Use with diabetes medications without glucose monitoring
  • Known citrus allergy1
  • Active liver disease or unexplained liver enzyme elevation should be clinician-managed1,3
Interactions

Interaction records.

ModerateSynergy

Berberine

Both may lower lipids and glucose, which can be useful but may increase hypoglycemia risk with diabetes medications.

Recommendation: Monitor glucose and lipids; avoid aggressive stacking if using glucose-lowering prescriptions.

InfoSynergy

Coenzyme Q10

CoQ10 is often paired with lipid-lowering strategies to support mitochondrial function, though direct bergamot-CoQ10 outcome data are limited.

Recommendation: Reasonable to combine, especially if also using statin-like products, but do not assume muscle-symptom prevention.

ModerateCaution

Green Tea Extract

Both can cause GI upset, and concentrated green tea extract has liver-injury concerns at high EGCG doses.

Recommendation: Avoid high-dose hepatotoxic stacks and check liver enzymes if symptoms or liver risk are present.
