First seen Nov 19, 2025 · Last updated May 01, 2026 · Updated 28 times
Summary
This study looks at whether taking a daily multivitamin can prevent vitamin and mineral deficiencies in people using GLP-1 weight-loss drugs like tirzepatide. About 246 adults with obesity who have been on a stable GLP-1 dose for at least 3 months will be randomly assigned to take either a multivitamin or a placebo for 12 months. Researchers will measure key nutrients like vitamin B12, vitamin D, and iron in the blood to see if supplementation makes a difference.
