Interaction reference
GLP-1 receptor agonists with Creatine
Creatine is widely used on GLP-1 therapy to preserve muscle mass during rapid weight loss. There is no documented interaction; the pairing is considered synergistic for body composition.
Creatine is one of the most useful supplements to take with a GLP-1 — it helps preserve muscle during weight loss, with no interaction concern.
Also known as: creatine monohydrate, creatine supplements
Per-GLP-1 breakdown
- Wegovysemaglutide 2.4 mgNo documented interaction
Mechanism: Creatine is cleared renally and does not interact with GLP-1 pharmacokinetics. It draws water into muscle cells, which is why hydration matters.
What to do: Creatine monohydrate 3-5 g daily supports muscle retention during GLP-1 weight loss, especially combined with resistance training. Drink extra water — both creatine and GLP-1s raise dehydration and constipation risk. No timing restriction relative to the injection.
- ZepboundtirzepatideNo documented interaction
Mechanism: Creatine is cleared renally and does not interact with GLP-1 pharmacokinetics. It draws water into muscle cells, which is why hydration matters.
