Frequently Asked Questions

Do GLP-1 users need protein powder?

Not necessarily. Whole foods can cover protein needs for many people. Protein powder is simply a convenient tool for days when appetite is low or meals are smaller than usual.

Is whey or plant protein better on Ozempic?

Whey isolate is often easier to hit high protein with fewer calories, while plant protein is useful for dairy-free or vegan users. Tolerance matters more than the label.

Can protein powder worsen nausea or constipation?

It can for some people, especially if mixed too thick, consumed too quickly, or used without enough fluids and fiber. Start with small servings and ask your clinician or dietitian if symptoms persist.
