• Protecting your bones on a GLP-1: bone density, fracture risk, and what actually helps · Losing a lot of weight usually costs a small amount of bone, mostly at the hip, and GLP-1 weight loss is no exception. So far the fracture data are reassuring and the drug itself does not look like the main cause, but the long-term evidence is thin. Here's what the bone-density and fracture studies show, who should pay the most attention, and the levers that kept bone steady in trials: resistance and impact training, protein, calcium and vitamin D, and a well-timed bone scan.
• Physician's Choice Digestive Enzymes & 60 Billion Probiotic: are they worth it on a GLP-1? · Physician's Choice markets these two supplements together in a "Hack Your Tummy" TikTok campaign for bloating and post-meal discomfort, a real complaint for GLP-1 users.
