Bergamot Benefits: 6 Science-Backed Uses And Dosage
Discover the science-backed health benefits of bergamot, from heart health and cholesterol management to stress relief and skin care.
Bergamot (Citrus bergamia), a citrus fruit primarily grown in southern Italy, offers promising health benefits supported by clinical research. Its extracts, polyphenols, and essential oil have shown effects on cholesterol levels, inflammation, cardiovascular health, stress reduction, and skin conditions.
What Is Bergamot?
Bergamot is a small, pear-shaped citrus fruit native to the Calabria region of southern Italy. Unlike common citrus fruits, it is rarely eaten fresh due to its bitter taste but is widely used for its peel, from which essential oil and polyphenol extracts like bergamot polyphenolic fraction (BPF) are derived. These contain flavonoids such as neoeriocitrin, naringin, and neohesperidin, which drive its therapeutic potential.
The fruit’s essential oil is famously used in Earl Grey tea and perfumes for its aromatic profile, but scientific interest focuses on its bioactive compounds. Studies highlight doses of 150–1000 mg/day of bergamot flavonoids for 30–180 days in humans, showing benefits for lipid profiles and more.
Potential Health Benefits of Bergamot
Research, including human trials with over 1,700 participants and animal models, supports bergamot’s role in multiple areas. Key benefits include cardiovascular support, anti-inflammatory effects, blood sugar regulation, mood enhancement, and skin health.
1. May Promote Heart Health
Bergamot extracts significantly improve lipid profiles, a key factor in heart disease prevention. Clinical trials show reductions in total cholesterol (up to 31.3%), LDL cholesterol (7.6–40.8%), and triglycerides (11.5–39.5%), with increases in HDL cholesterol (up to 39%).
In one trial, bergamot juice (20 mg/kg) reduced cholesterol by 29.27%, triglycerides by 46.12%, and LDL by 51.72%, while boosting HDL by 27.61%. BPF at 500–1000 mg/day lowered total cholesterol from 262 to 196 mg/dL and LDL from 175 to 116 mg/dL after 30 days. These effects are linked to bergamot’s activation of AMPK and inhibition of cholesterol ester hydrolase.
2. May Help Lower Cholesterol Levels
Bergamot is particularly noted for cholesterol management in hyperlipidemia patients. A systematic review of randomized trials confirmed consistent LDL and total cholesterol reductions across doses. Doses of 500 mg bergamot fruit extract daily for 12 weeks reduced total cholesterol by 7.3% and LDL by 10%.
| Study | Dose | Duration | Total Cholesterol Reduction | LDL Reduction |
|---|---|---|---|---|
| BPF Trial 1 | 500–1000 mg | 30 days | 25% | 34% |
| Bergamot Juice | 20 mg/kg | Variable | 29.27% | 51.72% |
| Phytocomplex | Standardized extract | Recent RCT | 12.3–31.3% | 7.6–40.8% |
These results position bergamot as a natural adjunct for those unable to tolerate statins, though larger trials are needed.
3. Contains Powerful Antioxidants
Bergamot’s flavonoids act as antioxidants, combating oxidative stress linked to chronic diseases. Its polyphenol fraction reduces lipid peroxidation and supports vascular health. Animal studies show liver protection in nonalcoholic fatty liver disease models via anti-inflammatory polyphenols.
4. May Reduce Inflammation
Bergamot exhibits anti-inflammatory properties by lowering pro-inflammatory cytokines. In animal models, bergamot juice (20 mg/kg) reduced inflammation markers. BPF shows promise for conditions like inflammatory bowel disease, though human data is emerging. Topical application decreased psoriatic plaques and boosted skin collagen.
5. May Help Reduce Stress and Improve Mood
Bergamot essential oil (BEO) in aromatherapy reduces anxiety and fatigue. A 2015 study found inhaled bergamot vapor lowered stress in women. BEO aromatherapy also decreased blood pressure and improved mental conditions compared to baseline. However, some trials (15–30 min sessions) showed no superiority over placebo for nausea or severe anxiety.
- Inhaled BEO: Reduces diastolic/systolic pressure and enhances mood.
- Topical BEO: Supports mental wellness via calming effects.
6. Other Potential Benefits
- Blood Sugar Control: Animal studies with 500–1000 mg/day BE for 30 days improved glucose metabolism.
- Skin and Hair Health: Topical bergamot (42 days) increased collagen, reduced psoriasis, and promoted hair growth.
- Bone Health: BEO (10–20 mg/kg, 20 weeks) increased bone volume in animals.
- Digestion and Antibacterial Effects: Supports gut health and has antibacterial properties for skin care.
How to Use Bergamot
Bergamot is available as supplements (BPF, extracts: 150–1000 mg/day), essential oil for aromatherapy/diluted topical use, or juice. For cholesterol, oral flavonoids 30–180 days; for stress, inhale 15–30 min daily. Always dilute oil (1–2% in carrier) to avoid irritation.
- Oral Supplements: 500 mg/day for lipids; consult doctor.
- Aromatherapy: Diffuse or inhale vapor.
- Topical: For skin, test patch first.
Possible Side Effects and Risks
Bergamot is generally well-tolerated in trials up to 12 weeks. Mild gastric pyrosis occurred in some at 500–1000 mg BPF. Essential oil is phototoxic—avoid sun exposure after skin application to prevent burns. Not for pregnant/breastfeeding without medical advice; may interact with statins or cholesterol meds.
Who Should Avoid Bergamot?
- Pregnant or nursing individuals.
- Those with citrus allergies.
- People on cholesterol-lowering drugs (monitor levels).
Consult healthcare providers before starting, especially with conditions.

Bottom Line
Bergamot offers evidence-based benefits for lipid management, inflammation, and mood, primarily from high-quality human and animal studies. While promising as a natural supplement, it’s not a replacement for medical treatment—combine with diet, exercise, and professional guidance for optimal results.
