Berberine
Metabolic
Plant alkaloid studied for blood glucose and lipids. Marketed dishonestly as "natural Ozempic" — it is not.
What the evidence says
Multiple human trials show meaningful glucose and lipid improvements, several comparing it to metformin. It is NOT a GLP-1 and does not produce GLP-1-scale weight loss.
What studies used
500 mg 2–3× daily in trials. With meals.
Reported from published studies and product labelling — a record of what was used in research, not a recommendation. What is right for you is a conversation with a clinician.
Watch out for
- GI upset is common
- Meaningful drug interactions via CYP enzymes
- Do not combine with glucose-lowering medication without medical input
Evidence base
established literature
Strong human evidence: either a phase 3 or 4 trial report alongside review-level evidence, or ten or more randomised controlled trial reports.
This letter measures how much human research exists, not whether it works for you — the tier above (Moderate) is the read on quality.
