Berberine & Metabolic-Support Supplements
Berberine earned the nickname "nature’s Ozempic," which oversells it — but it does have real human evidence for glucose and lipid markers. The catch is tolerability: berberine commonly causes cramping and diarrhea, and the effective dose (around 1,000 mg+ per day) is more than many stomachs handle comfortably. Here is how the main berberine products compare, and why some people look for a gentler approach.
