Gold Standard 100% Whey
by Optimum Nutrition · Budget whey blend
The category benchmark: ~24 g protein, whey blend, wide flavor range, budget-friendly per serving. A few additives, but the value is hard to beat.
24g per scoop, whey isolate + concentrate blend, widely available. Not the cleanest label in this list (contains sucralose and acesulfame-K) but the most accessible, available at Costco, Target, and Amazon at under half the price of the premium tier. A fine starting point if you're figuring out whether protein powder works for you before spending more on a cleaner formulation.
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.
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.
