GLP-1 Protein Bar Checklist
Before you buy any protein bar on Ozempic, Wegovy, Mounjaro, or Zepbound — check these five things.
The GLP-1 Protein Checklist
- ✅ Zero sugar alcohols — no erythritol, maltitol, sorbitol, or xylitol in the ingredient list
- ✅ Zero high-intensity sweeteners — no sucralose, acesulfame potassium, stevia, or monk fruit (even plant-derived, these can irritate a GLP-1 stomach)
- ✅ Zero seed oils — no sunflower, canola, soybean, or palm kernel oil
- ✅ Short ingredient list — 10 ingredients or fewer; ideally 4–7
- ✅ Ingredients you recognize — whole foods you could find in a grocery store
Why This Matters on GLP-1
GLP-1 medications like Ozempic, Wegovy, Mounjaro, and Zepbound slow gastric emptying — meaning food stays in your stomach significantly longer than usual. Ingredients that might be tolerable under normal digestion can cause nausea, bloating, and cramping when they sit in a GLP-1 stomach for hours.
Sugar alcohols, artificial sweeteners, and fiber additives are the three biggest culprits. In our review of 11 top-selling protein bar brands, all 11 contain at least one of these categories. Zero brands meet all five checklist criteria — except one.
🚩 Red Flags to Look For
- Erythritol, maltitol, sorbitol, xylitol, isomalt — any sugar alcohol
- Sucralose, acesulfame potassium, "stevia extract" — any high-intensity sweetener (even plant-derived)
- Chicory root fiber, inulin, soluble corn fiber, polydextrose — fermentable fiber isolates
- Sunflower oil, canola oil, soybean oil, palm kernel oil — seed oils
- "Natural flavors" — an umbrella term for up to 100+ flavoring compounds
