What it is
Berberine is a yellow alkaloid extracted from several plants including barberry and goldenseal. It has a long history in Traditional Chinese Medicine and Ayurveda for digestive and metabolic complaints.
How it works
By activating AMPK, berberine influences the way cells handle glucose and lipids. Some studies show meaningful effects on fasting glucose, comparable to early-line metabolic medications — though the comparison is not equivalence.
The protocol
500 mg up to three times daily with meals.
Sourcing
Berberine HCl is the standard. Look for third-party tested products that disclose actual milligrams per capsule.
Honest caution
Can interact with several medications including blood-glucose drugs and antibiotics. Consult a clinician before combining with prescription medication.
What it supports
- Glucose support — Activates AMPK and supports healthy fasting glucose.
- Lipid balance — Studied for its effects on cholesterol and triglyceride markers.
