Berberine is a botanical compound found in plants including barberry, goldenseal, Oregon grape, and tree turmeric. Used in Ayurvedic and Chinese Medicine for hundreds of years, berberine's diverse benefits and mechanisms of action are also supported in modern research. Its primary mechanism is its ability to activate the enzyme Adenosine Monophosphate-Activated Protein Kinase (AMPK) while inhibiting Protein-Tyrosine Phosphatase 1B (PTP1B).
Clinical evidence shows that Berberine may help to support and promote glucose and lipid metabolism. Berberine is also an anti-bacterial and it may help to protect the gastrointestinal system. Further, it promotes cellular antioxidant defense and exhibits anti-inflammatory effects.
Patient One Berberine supplies 500 mg berberine HCl per capsule, the dosage used in clinical trials for glucose and lipid health.
Berberine has been shown to lower total and LDL cholesterol among diabetic participants in several controlled trials.
In controlled trials berberine reduced HbA1c levels in diabetic participants with comparable efficacy to metformin. Among participants with the metabolic syndrome berberine has been shown to reduce waist circumference and body weight, blood pressure, triglycerides, and improve insulin resistance compared to placebo, with similar benefits in women with Polycystic Ovary Syndrome (PCOS).
A clinical trial comparing standard therapy with or without berberine among patients receiving percutaneous coronary intervention showed improvements in multiple inflammatory markers.
