What it is

20g per scoop, whey protein isolate, NSF Certified for Sport. Short ingredient list, no artificial colors or sweeteners. It mixes thin in water, which matters when a shake is replacing part of a meal on a day nothing sounds good. Blended with frozen berries and a banana, it hits a 30g breakfast target without asking a shrunken appetite to chew.

Why it matters on a GLP-1

When you lose weight on a GLP-1, a meaningful share of it can come from lean muscle, not just fat. Hitting a protein target helps protect that muscle, but a shrunken appetite makes eating enough genuinely hard, which is where a clean, easy-to-tolerate protein powder earns its place as a bridge.

How to use it

A shake is most useful when appetite is quietest, often at breakfast, or as a stand-in when a meal just isn't happening. Liquid protein tends to go down easier than whole cuts of meat on a slow-emptying stomach. Look for a short ingredient list and a sweetener you tolerate; some people find sucralose-heavy formulas rough on an already-sensitive gut.
