What it is

25g per scoop, grass-fed whey isolate, unflavored and lightly flavored versions available. The unflavored blends invisibly into yogurt, soup, or oatmeal, which is useful when a full shake is too much volume but protein still needs to land. No artificial sweeteners in the unflavored version. One of the better mid-tier options for GLP-1 users who want flexibility in how protein gets in.

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.
