Does berberine help with cholesterol? What the research does and doesn't show

The evidence doesn't support berberine at low or typical single-ingredient supplement doses as a way to lower cholesterol — the trials that found an effect used 300 mg to 1.5 g of berberine a day, well above what many supplements provide. Multiple meta-analyses at that dose range found real reductions in LDL, total cholesterol and triglycerides, but the effect is not established at lower doses, and HDL didn't improve in any of them.

What the evidence doesn't support

It doesn't support berberine as a replacement for a prescribed cholesterol medication, and no trial has tested it as a substitute for one. It also doesn't support a cholesterol benefit at doses below the roughly 300 mg to 1.5 g a day the trials actually used — a lower dose is untested, not proven to work the same way. And it doesn't support any effect on HDL cholesterol specifically: every meta-analysis below found HDL unchanged or, in men, slightly lower.

What the trials found

A 2018 meta-analysis of 16 randomized trials in 2,147 adults with dyslipidemia found total cholesterol, LDL and triglycerides each decreased at doses of 0.6 to 1.5 g of berberine a day. A 2023 meta-analysis of 18 placebo-controlled trials in 1,788 adults found similar LDL and total cholesterol reductions at the same dose range, with HDL response differing by sex — slightly higher in women, slightly lower in men. A 2023 meta-analysis of 20 trials in 1,761 adults, mostly with impaired glucose metabolism, found fasting glucose and a marker of insulin resistance improved at 0.6 to 1.5 g a day. A 2025 meta-analysis of 12 placebo-controlled trials in 889 adults with metabolic syndrome found triglycerides and waist circumference decreased at 300 mg to 1.5 g a day, with no significant change in HDL, systolic or diastolic blood pressure. A smaller 2008 randomized trial in 116 adults with type 2 diabetes and dyslipidemia found triglycerides and total cholesterol decreased over three months at 1 g a day compared with placebo.

Across every trial above, the dose used was 300 mg to 1.5 g of berberine a day — none tested a dose below 300 mg. The review authors of the largest analyses also noted that trial quality was generally rated low to moderate, with a high risk of bias in several included studies, and that many of the dyslipidemia trials came from mainland China or Hong Kong, which limits how confidently the results generalize to other populations.

Study (year, design)	Population	Dose	Finding
2018 meta-analysis, 16 RCTs, n=2,147	Adults with dyslipidemia	0.6-1.5 g/day	Total cholesterol, LDL and triglycerides decreased
2023 meta-analysis, 18 RCTs, n=1,788	Adults with dyslipidemia	0.6-1.5 g/day	LDL and total cholesterol decreased; HDL response differed by sex
2023 meta-analysis, 20 RCTs, n=1,761	Adults, mostly impaired glucose metabolism	0.6-1.5 g/day	Fasting glucose and insulin resistance marker improved
2025 meta-analysis, 12 RCTs, n=889	Adults with metabolic syndrome	0.3-1.5 g/day	Triglycerides and waist size decreased; HDL and blood pressure unchanged
2008 RCT, n=116	Type 2 diabetes with dyslipidemia	1 g/day, 3 months	Triglycerides and total cholesterol decreased vs. placebo

Questions people ask

Does berberine lower cholesterol?

At 300 mg to 1.5 g a day — the dose range every trial above used — multiple meta-analyses found LDL, total cholesterol and triglycerides decreased. No trial has tested a lower dose, so that finding doesn't extend below roughly 300 mg a day.

Does berberine lower LDL?

Yes, at the doses studied. Two large meta-analyses (16 and 18 trials) each found LDL decreased at 0.6 to 1.5 g of berberine a day.

How much berberine is needed to lower cholesterol?

The trials above used 300 mg to 1.5 g a day. No study has tested whether a smaller amount produces a similar result, so a lower dose can't be assumed to work the same way.

Does berberine lower triglycerides?

Yes, in the populations and doses studied — three of the meta-analyses above found triglycerides decreased at 0.3 to 1.5 g of berberine a day.

Is berberine good for high cholesterol?

The trial evidence at 0.6 to 1.5 g a day supports a real effect on LDL and total cholesterol in adults with dyslipidemia. That's a statement about the research at that dose, not a recommendation to self-treat diagnosed high cholesterol instead of following medical guidance.

When to talk to a doctor

Diagnosed high cholesterol calls for medical guidance, not a supplement search — berberine is not a substitute for a prescribed cholesterol medication, and no trial has tested it as one. If you take a cholesterol medication or any other prescription, ask a doctor before adding berberine; the doses studied above are well above what many supplements provide, and combining a higher dose with medication that lowers lipids the same way hasn't been specifically tested.
