Here it is: Berberine by Barton Nutrition is a doctor-formulated metabolic health supplement containing a clinically studied 800 mg dose of berberine extract paired with milk thistle for maximum absorption. Formulated by Dr. Scott Saunders, a Doctor of Integrative Medicine, this two-ingredient formula is designed to support healthy blood sugar levels, improve insulin sensitivity, promote healthy weight management and metabolism, reduce sugar and carb swings, and support healthy cholesterol and lipid levels. Each bottle contains 60 capsules (a 30-day supply at the recommended dosage of 2 capsules per day, taken before meals). Berberine works by activating AMPK, often called the body's "metabolic master switch," a crucial enzyme that helps the body process glucose and fat more efficiently. Because standard berberine supplements suffer from poor bioavailability — with the body absorbing only about 5% — this formula includes milk thistle extract to significantly boost absorption and effectiveness. Berberine is ideal for adults looking to curb cravings, support healthy weight loss, and balance blood sugar naturally without injections or extreme diets. It helps boost the body's own GLP-1 and AMPK production, which naturally decline with age. Clinical research has shown berberine can support healthy changes in weight, BMI, and waist circumference within 12 weeks, with study participants demonstrating a 38% improvement in insulin sensitivity and glucose metabolism. This supplement pairs well with other Barton Nutrition products including CinnaChroma for additional blood sugar support, TurmericBP+ for cardiovascular health, and Fiber Greens for gut health. Barton Nutrition is a family-owned supplement company operating since 2004, and all products are research-backed, third-party tested, and made in the USA. Berberine is backed by a 90-day money-back guarantee with free shipping on all orders.
