Bergamot dosage and evidence
Written by Aaron CuhaReviewed Sep 2026
The short answer
Fourteen small studies show big drops in blood fats, including LDL (bad) cholesterol down 55 mg/dL. That is a surprisingly large effect for a fruit extract. The studies are small, mostly from one region, and none has measured heart attacks or strokes.

In plain English, from Aaron
This is how I would explain it to a friend. The evidence, with the numbers, is further down the page.
Bergamot is a citrus fruit grown in Italy. The pills are an extract of its plant compounds. People take them to lower cholesterol. It is a supplement, not a drug.
What people take it for
- Lower LDL cholesterol without a statin.
- Lower triglycerides, a blood fat.
- A natural swap for a statin.
What studies in people showed
A review pooled 14 small studies. LDL fell about 55 mg/dL. Triglycerides fell about 75 mg/dL. That is close to what a moderate statin does. That is also why I do not fully trust it. The studies are small. Most come from the part of Italy that grows the fruit and makes the extract. The reviewers said results were not the same from one product to the next. No study has checked heart attacks, strokes or deaths. Every result is a number on a blood test.
What people report
Reports, not study results
The good
- In the pooled studies on this page, LDL and triglycerides fell by large amounts.
The bad
- The studies on this page do not report side effects, and we have not collected user reports on this one yet.
- Products differ. The review found results were not the same from one bergamot product to the next.
Where these come from: The blood fat numbers come from the review on this page. We have not collected user reports on this one yet.
My bottom line
In my opinion, this is a cheap thing to try if your cholesterol is stubborn. Test your blood fats first, pick a product a study used, and test again. If the numbers do not move, stop. It is not a swap for a statin your doctor says you need.
An opinion, not a finding. I am a coach, not a doctor.
What it has been measured to do
Nothing indexed yet
The 1 citation on this page do not report a result for any of the 36 goals indexed here. Most of what sits here is something else: a listing of a planned study, a study of how the body handles the drug, a safety report or a government record. None of those tests whether it works.
When this earns a spot
It earns a spot when LDL particles are small and dense, or when your doctor is already watching ApoB. It does not earn a spot as a statin replacement. The studies are small and only measured cholesterol numbers.
Aaron's list, tier 2
Bloodwork that belongs beside the bottle
ApoB plus a standard cholesterol panel. Testing particle pattern is optional.
Test again after about 90 days. If that blood number did not move, stop.
- LDL can look fine when ApoB is not.
- Lp(a) will not move. Measure it once so you do not blame the bottle.
Reading the number
If ApoB did not move, stop. If a doctor started a real cholesterol medicine, they own the retest, and bergamot is not the hero of that story.
What these tests mean: ApoB, LDL cholesterol.
What people typically order
Ask for ApoB, a cholesterol panel, and one Lp(a). Partners on /bloodwork/partners differ on whether they include ApoB. Read what each panel covers.

What is Bergamot?
Fourteen small studies show big drops in blood fats, including LDL (bad) cholesterol down 55 mg/dL. That is a surprisingly large effect for a fruit extract. The studies are small, mostly from one region, and none has measured heart attacks or strokes.
Bergamot is a citrus fruit. An extract of its plant compounds (polyphenols) has been tested on blood fats in people. The honest reading is that the effect looks real and is hard to believe.
A review that pooled 14 studies found total cholesterol down 63.6 mg/dL, LDL (bad) cholesterol down 55.4 mg/dL and triglycerides down 74.7 mg/dL. Those numbers are in the range of a moderate statin dose, from a fruit extract. The same reviewers said results were not consistent across products that contain bergamot. They said better studies are needed to show it truly works.
When results look that big, there are two options. Either the extract is truly strong, or the studies have problems. This page gives you the numbers and the reasons for caution together, rather than picking one.
How does Bergamot work?
The extract is rich in plant compounds called flavanones, mainly brutieridin and melitidin. Part of their shape looks like the working part of a statin. That led to the idea that bergamot partly blocks the same enzyme statins block, like a weak statin. Other ideas: it may switch on an energy sensor in cells (AMPK), and it may cut how much cholesterol your gut absorbs. The statin-like idea is a guess based on shape, backed by lab and animal work. It has not been shown in people.
What have studies in people found about Bergamot?
A small set of human studies reports strikingly big changes in blood fats. No study has measured heart attacks, strokes or deaths.
- 14 studies pooled: LDL (bad) cholesterol down about 55 mg/dL and triglycerides down about 75 mg/dL, compared with the control groups.
- Each study was small. Most come from one research community in Italy, where the fruit is grown and the extract is made.
- Every result is a blood fat number. No study has measured heart attacks, strokes or deaths.
- The reviewers say results were not consistent across different bergamot products. That points to products that vary, rather than one reliable treatment.
What this does not tell you: When a food extract shows effects this big, ask whether the studies measure what they seem to. Small studies from one region with big effects are the classic setup for a result that shrinks once better studies arrive. That has happened again and again with supplements. Products are also not standardised. A good study of one extract says little about a different bottle. And lowering a blood fat number is not the same as preventing a heart attack. No bergamot study has tried to test that.
The state of the research
Bergamot sits in a tricky middle zone. There are human studies, which is more than most supplements have. But they are not solid either. Small studies, and the habit of publishing good results more than empty ones, would both push results in the direction seen here. Most studies also come from the region that makes the extract. That is a reason for care, not an accusation. The fair summary: if your blood fat numbers are hard to fix, this is a cheap, low-risk thing to try, and you can measure whether it works for you. There is no basis for believing it prevents heart attacks or strokes.

Fig. 4 · how much does what
Nobody has tested different amounts in people
This chart would show how the effect changes as the amount goes up. For this compound, nobody has measured that in people. So we leave it empty. We will not borrow an animal chart and pretend it works the same in people.
Fig. 5 · what the molecule is
- Kind of compound
- Supplement
- Molecule weight
- Not a single molecule. A standardised polyphenol extract, and products differ in flavanone content, which is the main reason results may not transfer between them.
- Half-life
- Stated in words, not a numbersee the exact wording below
- Chain length
- None on file
Half-life as stated on file: Not well characterised in humans. Citrus flavanones are extensively metabolised by gut microbiota and conjugated in the liver, and plasma appearance of metabolites differs substantially between people.
No amino acid sequence is on file for Bergamot, which is expected: a supplement is not built from amino acids.
The studies we cite
- Review of studies2022The effect of bergamot supplementation on lipid profiles: a systematic review and meta-analysis of randomized controlled trials
Across 14 studies, bergamot extract lowered blood fats by large amounts. LDL (bad) cholesterol fell about 55 mg/dL and triglycerides about 75 mg/dL. HDL (good) cholesterol rose 5.78 mg/dL. The reviewers said results were not consistent across products that contain bergamot. They said better studies are needed to prove it works.
14 randomised trials. Total cholesterol minus 63.60 mg/dL (95% CI minus 78.03 to minus 49.18), triglycerides minus 74.72 mg/dL, LDL minus 55.43 mg/dL and HDL up 5.78 mg/dL, all p < 0.001. The authors state that results for nutraceutical compounds containing bergamot were inconsistent and that clinical efficacy needs establishing through higher-quality studies.
Common questions
Has Bergamot been tested in people?
Not in any study cited here. Fourteen small studies show big drops in blood fats, including LDL (bad) cholesterol down 55 mg/dL. That is a surprisingly large effect for a fruit extract. The studies are small, mostly from one region, and none has measured heart attacks or strokes.
What is the Bergamot dosage?
No human dose established. No published study on this page has given this compound to people and reported a result. no study cited on this page yet
Is Bergamot FDA-approved?
Sold as a dietary supplement. Not approved to treat unhealthy cholesterol and blood fat levels, or anything else.
Does bergamot really lower LDL by 55 points?
That is what a review of 14 studies reports. It is also a big enough effect to doubt, coming from a food extract. The studies are small and mostly from one region. The reviewers themselves call for better studies. Treat it as promising, not proven.
Is it a natural statin?
The interesting part of that claim is about shape. Two of its compounds have a part that looks like the working part of a statin. That makes it possible that it partly blocks the same enzyme. Nobody has shown that in people. Calling it a natural statin goes further than the evidence.
Does the product matter?
Probably a lot. This is an extract, not a single molecule, and products differ in how much of the key compounds they contain. The review found results were not consistent across bergamot products. If you try it, pick the same extract a study used.
