## Direct answer

Mounjaro and Zepbound are both tirzepatide from Eli Lilly at identical 2.5–15 mg weekly doses. The only meaningful differences are the approved indication — type 2 diabetes for Mounjaro, chronic weight management and obstructive sleep apnea in obesity for Zepbound — and how insurance covers each. Protein, electrolyte, magnesium, fiber, and vitamin needs are the same on both.

## What changes for nutrition

- Nothing about the molecule differs, so no supplement should be swapped when switching brands.
- Weight-management users on Zepbound often lose faster, which raises the priority of protein and resistance training.
- Both brands suppress appetite most in the 24–72 hours after injection; liquid protein and electrolytes cover that window.

## Verdict

Choose based on your diagnosis and insurance coverage with your prescriber.

Keep the same nutrition plan on either brand: protein first, electrolytes daily, magnesium at night, fiber for regularity.
