Experts weigh in on the safety and effectiveness of berberine as a weight-loss supplement.

TikTokers are promoting the supplement berberine for weight loss, calling it "Nature's Ozempic." Berberine is a botanical compound that has been used in traditional Chinese and Ayurvedic medicine for centuries. Some studies suggest that berberine may help with weight loss, but more research is needed to determine its effectiveness and safety. Berberine may cause minimal side effects such as diarrhea, constipation, and gas, and it may interact with certain medications and conditions. Experts recommend trying other avenues for weight loss before turning to supplements.
