What is Berberine?
Berberine is a plant alkaloid found in barberry, goldenseal, and Oregon grape. It activates AMPK, the same cellular energy sensor that metformin targets. Multiple randomized controlled trials show berberine reduces fasting glucose, HbA1c, and LDL cholesterol at doses of 500 mg three times daily. The effect size on HbA1c is comparable to metformin in head-to-head trials. Berberine has poor oral bioavailability (under 5%), and newer formulations (phytosomal, nanoparticle) aim to improve absorption.
Evidence grade: A. Plant-derived AMPK activator; near-drug-strength effects on blood sugar and lipids. Read the full evidence review: Berberine ingredient page.
How we rank Berberine supplements
Every Berberine product in our database is scored on five pillars:
- Dose honesty: Does the product contain the amount stated on the label? We check against published third-party assay results when available.
- Evidence: Berberine has evidence grade A. Products that cite relevant trials score higher.
- Price per month: Total monthly cost based on label serving recommendations.
- Third-party testing: Does the brand publish a Certificate of Analysis (CoA) from an independent lab?
- Transparency: Is the full formula public? Are all ingredient amounts disclosed?
See the full methodology for the scoring formula.
What to look for in a Berberine supplement
- Dose: 500 mg two to three times daily, taken with meals. Total 1,000 to 1,500 mg per day.
- Form: Standard berberine HCL is the most studied. Phytosomal formulations (Berberine Phytosome) may improve absorption 2-5x.
- Purity: Look for products with published CoA showing berberine HCL content.
- Price: Berberine is inexpensive. Standard formulations range from $10 to $25 per month. Phytosomal forms cost more.
- Testing: Third-party testing for heavy metals is important for plant-derived supplements.
