Frequently Asked Questions

Is creatine useful during GLP-1 weight loss?

Creatine may support training performance and lean-mass goals when paired with resistance training and adequate protein. It is not a substitute for food, exercise, or medical care.

Which form of creatine should I choose?

Creatine monohydrate is the default evidence-backed form. Micronized monohydrate can be easier to mix, but it is still the same core ingredient.

Can everyone take creatine?

No. People with kidney disease, pregnancy, medication concerns, or active medical issues should ask a clinician first. Follow the product label and your clinician guidance.
