Micronutrients & recovery
Multivitamin supplementation is recommended for individuals using GLP-1 receptor agonists to address micronutrient insufficiencies resulting from reduced caloric intake and gastrointestinal side effects.
Take a daily multivitamin while on GLP-1RA medication. Because you are eating less, you might not get enough vitamins from food alone. This helps protect your long-term health and prevents deficiencies.
ModerateSupportsMEDIUM confidence
Multivitamins are recommended to address micronutrient insufficiencies as determined by individual deficiencies and suboptimal intake.
Why this rating
Based on narrative review of general obesity/weight loss literature rather than specific GLP-1RA trials.
