Semaglutide and Ozempic have become popular names in the UK weight loss community, but which is truly more effective? Both contain the active ingredient semaglutide, yet differ in formulations, dosages, and licensing. Semaglutide (Wegovy) is specifically licensed for weight loss and offers impressive results with up to 15% body weight reduction in clinical trials, though it’s mostly available via private prescriptions. Ozempic, commonly prescribed for type 2 diabetes, carries weight loss benefits off-label and is more accessible through the NHS but with lower dosages. Learn the pros and cons, side effects, costs, and what current research says to decide which treatment matches your weight loss journey.
