Citrus Bergamot Dosage: How Much BPF Do the Trials Actually Use?
Educational summary — not medical advice. See the hub for the statin/CYP3A4 interaction caution before dosing. This statement has not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.
The honest answer
Trials in this evidence pack range 400–1300mg/day of bergamot polyphenolic fraction (BPF), with most positive results clustering in the 500–1000mg/day range. A 500mg/day dose produced no effect in one independent trial. There is no government RDA or upper limit for bergamot polyphenols — it's a food-derived extract, not an essential nutrient, so every number here is trial-derived, not physiologically anchored the way a vitamin dose would be.
What the trials actually used
Bergamot dosing across the human trials is more scattered than a typical single-nutrient supplement, partly because different products (BPF, Bergavit®, Brumex™, BPE-C) use different extraction and standardization methods that aren't directly interchangeable milligram-for-milligram. Gliozzi 2013 used 1000mg/day BPF added to a statin and found an enhanced LDL effect. Pierdomenico 2023 used a lower 400mg/day of a different extract (Brumex™) over 12 weeks and still found significant lipid improvements — the lowest effective dose in this evidence pack. Capomolla 2019 tested two doses head-to-head, 650mg/day and 1,300mg/day of a pectin-enriched formulation (BPE-C), and found the higher dose produced larger reductions in fasting glucose, triglycerides, and the atherogenic index — a plausible but not tightly characterized dose-response signal, since it comes from one trial testing one specific formulation. Toth 2015 used a different metric entirely: 150mg/day of disclosed flavonoids (not total BPF weight) from a Bergavit®-branded extract. And Bruno 2017 used the lowest dose in this pack, 500mg/day, over 60 days in psychiatric outpatients on antipsychotic medication — and found no metabolic improvement, a real null result in that specific population.
| Trial | Dose | Duration | Result |
|---|---|---|---|
| Pierdomenico 2023 | 400 mg/day (Brumex™) | 12 weeks | Significant TC/TG/LDL/ApoB100 reduction |
| Bruno 2017 | 500 mg/day (BPF) | 60 days | No effect (psychiatric outpatients on antipsychotics) |
| Gliozzi 2013 | 1000 mg/day (BPF) | 30 days | Enhanced statin LDL effect (added to rosuvastatin) |
| Capomolla 2019 (low) | 650 mg/day (BPE-C) | 90 days | Improved atherogenic index, smaller effect than high dose |
| Capomolla 2019 (high) | 1,300 mg/day (BPE-C) | 90 days | Largest effect in this evidence pack: TG −32%, glucose −18.1% |
Doses across trials are not strictly comparable milligram-for-milligram, since BPF, Bergavit®, Brumex™, and BPE-C are differently extracted and, where disclosed, differently standardized products. Treat this as the honest range the evidence covers, not a single validated dose-response curve.

Enter the total bergamot extract mg per serving from your label and how many servings you take per day. This checks total extract weight, not polyphenol-adjusted content — most labels don't disclose that figure.
How to think about dosing this honestly
- Target the 500–1000mg/day range if you're trying to approximate where most positive trials landed — but recognize that even inside this range, results have been inconsistent across trials and populations.
- Don't assume 500mg/day is automatically effective. That's the exact dose that failed in Bruno 2017. A product delivering 500-600mg/day with no standardization disclosed is a real double caution, not just a budget option.
- Don't chase doses above 1300mg/day expecting more benefit. No trial in this evidence pack tested higher doses, so there is no data showing 2,000mg/day or more does anything the tested range doesn't.
- Standardization matters more than the milligram number. A precise-sounding "1200mg" on an unstandardized label tells you less than a lower dose with a disclosed polyphenol percentage — see the buying guide.
- On a statin or other prescription medication? Talk to your clinician before starting, regardless of dose — see the safety note on the hub.
- Take with food. Trials dosed bergamot once daily or split across the day with meals; no dedicated timing study exists in this evidence pack.

Frequently asked questions
How much citrus bergamot should I take?
500-1000mg/day BPF covers most positive trials; the full evidence range is 400-1300mg/day. A 500mg dose produced no effect in one trial, so the low end isn't automatically effective.
Is there an official RDA or upper limit?
No. Bergamot polyphenols aren't an essential nutrient, so no deficiency state or government-set dose exists. All figures here are trial-derived.
Does a higher dose work better?
Plausible but not tightly established — one trial found 1,300mg outperformed 650mg. No trial tested above 1,300mg/day, so higher doses are simply untested.
Why did a 500mg dose fail in one trial?
Bruno 2017 found 500mg/day did not improve metabolic parameters in antipsychotic-treated patients over 60 days — a real null result in that population, not proof the dose never works.
