Anti-Inflammation & Antioxidants
Berberine
Also known as: Berberine HCl · Berberis aristata extract
One of the most clinically validated plant compounds. Activates AMPK (the 'exercise mimetic') and reduces blood glucose as effectively as metformin in head-to-head trials.

What Is Berberine?
Berberine is an isoquinoline alkaloid found in barberry, goldenseal, and tree turmeric. It has been used in Traditional Chinese and Ayurvedic medicine for thousands of years. Modern pharmacology has identified it as a potent AMPK activator with clinical evidence across metabolic syndrome, type 2 diabetes, and dyslipidaemia.
How It Works: The Science
Berberine inhibits mitochondrial Complex I, reducing ATP/AMP ratio and activating AMPK — the master cellular energy sensor. AMPK activation increases GLUT4 expression (glucose uptake), inhibits gluconeogenesis (HNF4α suppression), reduces fatty acid synthesis, and upregulates mitochondrial biogenesis. Berberine also modulates gut microbiota (increasing Akkermansia muciniphila) and inhibits intestinal alpha-glucosidase.
Primary Mechanism
AMPK activation, gut microbiome modulation, mitochondrial Complex I inhibition
Evidence-Based Benefits
Dosage Guide
Effective Dose
500mg × 2–3 / day
500mg, 2–3 times daily with meals (critical — take with food to maximise effect and reduce GI upset). Dihydroberberine is a more bioavailable form allowing lower doses. Cycle: 8 weeks on, 2–4 weeks off.
Safety Profile & Side Effects
GI upset (constipation, nausea) is common — start low and titrate up. Do not combine with metformin without medical supervision (additive blood glucose lowering). Inhibits CYP3A4 — significant drug interaction potential. Not recommended in pregnancy.
Who Should (and Shouldn't) Take It
Individuals with insulin resistance, pre-diabetes, type 2 diabetes (as an adjunct), or dyslipidaemia wanting a plant-based metabolic supplement. One of the most evidence-based supplements in the metabolic health space.
