Citrus bergamot is a small yellow citrus fruit grown almost exclusively on the Calabrian coast of southern Italy. The juice and pulp contain a rare combination of flavonoids that lower LDL cholesterol and triglycerides, raise HDL, and improve insulin sensitivity. It's one of the most researched natural interventions for dyslipidemia that isn't a drug.

Generally used as a first line defense and OTC alternative to bring cholesterol numbers down without going on a statin, but also works along side statins. It's also relevant for anyone with metabolic syndrome, fatty liver (NAFLD), insulin resistance, or anyone exogenous hormones that have pushed their lipids in the wrong direction.

There are two very different bergamot products on the market, and confusing them is the single most common mistake. Bergamot essential oil (cold-pressed from the peel) is the stuff in perfume and Earl Grey tea. It contains furocoumarins like bergapten and bergamottin that are phototoxic on the skin and can interact with drugs. Don't take it orally for cholesterol. The bergamot polyphenolic fraction (BPF), a standardized extract made from the juice and pulp, is what the clinical trials used. When this page talks about bergamot supplements, it means BPF or a comparable standardized flavonoid extract. Essential oil is a separate product with separate uses and separate risks.

Dosage:

• Starting and standard dose: 500 my taken once or twice a day of standardized BPF (bergamot polyphenolic fraction), taken 15-30 minutes before the main meal of the day. Most clinical benefit is seen in this range
• Higher-end dose for poor response or statin-intolerant patients: 1500 mg/day, split into two doses (before lunch and before dinner). This is the dose used in the Mollace 2011 statin-intolerant arm
• Phytosomal / lecithin-formulated bergamot: 300 mg/day (typically 150 mg twice daily). The phytosomal form has higher bioavailability, so the effective dose is lower. If the label says phytosome, phytosomal, or lecithin-formulated, don't just match the milligrams of standard BPF
• Standardized flavonoid extracts (e.g. Bergavit40): 150 mg/day of flavonoids (which typically corresponds to around 500-550 mg of extract), taken with the evening meal
• Timing: Take before meals rather than after. The cholesterol-ester-hydrolase inhibition and the interference with dietary cholesterol absorption both require bergamot to be present in the gut when food arrives
• Duration to see results: Lipid changes are typically visible on bloodwork at 4-8 weeks. Maximum effect usually by 3-6 months. Bergamot is a long-term intervention, not an acute one
• What to look for on a label: standardization to flavonoids (usually 38-47% total flavonoids), and ideally an explicit statement of brutieridin and melitidin content. Extracts without these two compounds are probably just naringin and are unlikely to work as well. "Bergamot extract" with no standardization on the label is a gamble
• Stacking: pairs well with berberine (complementary AMPK activation plus glucose effects), omega-3s (triglyceride reduction through a different mechanism), and red yeast rice or a low-dose statin for additive LDL lowering. If stacking with a statin, check liver enzymes at 6-8 weeks since both act on the liver, though no meaningful hepatotoxicity signal has been reported for the combination

Here's what you can expect:

If your baseline LDL or triglycerides are elevated, you should see measurable movement on a lipid panel at 4-8 weeks, with the full effect usually landing by 3-6 months. Expect roughly 15-30% reductions in total cholesterol and LDL, 15-40% reductions in triglycerides, and a 5-40% increase in HDL, depending on how high your baseline was and which extract you're using. Higher baselines see bigger absolute changes. If your baseline lipids are already excellent, the effect will be small and probably not worth the cost.

On glucose, if you have insulin resistance or metabolic syndrome, expect a modest drop in fasting glucose (5-20%) and improvement in HOMA-IR over the same 3-6 month window. Subjectively, most people don't feel anything on bergamot the way they'd feel caffeine or creatine. It's a quiet intervention that shows up on bloodwork, not in the mirror. Some users report slightly better exercise tolerance and recovery, which lines up with the endothelial and nitric oxide data.
