-
Evidence quality
Some research supports it; other claims overreach.
-
Clinical dose
1000-1500 mg daily based on study doses (likely low)
-

Generic berberine supplements (Amazon, iHerb, Nature's Way) at $10-15 for similar quantity; prescription metformin for diabetes management.
Consumer advice
- • If you want berberine, this is a decent option—third-party tested, transparent dosing, and a reputable brand. However:.
- • You'll need 2-3 capsules daily to hit clinical doses (1000-1500mg), which means the '2-month supply' claim is misleading;.
- • Check cheaper alternatives on Amazon or iHerb first—you can save $5-8 per bottle;.
- • Berberine works best for people with confirmed metabolic issues (high cholesterol, prediabetes, PCOS)—don't expect dramatic weight loss or anti-aging if you're healthy;.
