What does Bergamot Extract do?

Citrus extract with moderate evidence for lowering LDL cholesterol and triglycerides, especially in combination formulas.

Is Bergamot Extract safe?

Most positive trials used combination products (with plant sterols, berberine, artichoke, etc.), making it hard to isolate bergamot's individual contribution

Bergamot Extract - Science-Based Research

What the Science Says

Bergamot extract comes from the rind and juice of the Citrus bergamia fruit and is rich in polyphenols like naringin. Several clinical trials show it can meaningfully reduce LDL cholesterol, total cholesterol, and triglycerides while raising HDL cholesterol, particularly in people with dyslipidemia or metabolic syndrome. Some studies also report improvements in blood sugar, insulin resistance, and inflammatory markers like hs-CRP, with effects typically seen after 8–12 weeks of daily use.

What It Doesn't Do

Not a guaranteed cholesterol fix — one well-designed trial found no significant LDL reduction when combined with plant sterols and artichoke extract. Won't replace statins for high-risk patients. No solid human evidence it fights cancer or viruses. The gut microbiota benefits seen in studies are from animal models only. Don't expect results in days — most studies ran 8–12 weeks minimum.

Moderate Evidence

Effective at: 120-500 mg polyphenols daily based on study doses

Absorption & Bioavailability

Moderate — standard polyphenol formulations show limited absorption. A phytosomal (lecithin-bound) formulation showed at least 2.5x higher absorption of naringin in human studies, though clinical outcomes were similar between formulations in one trial.

Red Flags to Watch For

Most positive trials used combination products (with plant sterols, berberine, artichoke, etc.), making it hard to isolate bergamot's individual contribution
One rigorous RCT (n=42, 4 months) found no significant LDL reduction for a bergamot-containing combination product — results are not guaranteed
Bergapten (a compound in bergamot essential oil) is a photosensitizing agent and has separate pharmacological effects — not all bergamot products are equivalent
Many studies are small (30–90 participants) and short-term; long-term safety and efficacy data are limited
Products vary widely in standardization — 'bergamot extract' on a label doesn't guarantee a specific polyphenol dose
