Best value protein isolate for GLP-1 users

Quick answer

If you want a clean whey isolate without the premium price, Optimum Nutrition Gold Standard 100% Isolate is the best-value pick for GLP-1 users. Each scoop gives 24 grams of ultra-filtered, partially hydrolyzed whey with under a gram each of fat and carbs, so it is nearly pure protein in a low-volume serving that suits a suppressed appetite. The cost per serving runs lower than most hydrolyzed isolates, which adds up when protein is a daily, repeat purchase. It is dairy-based, so it is not the choice if lactose upsets your stomach, and the isolate line has fewer flavors than the standard Gold Standard range. But for a budget-conscious user who still wants a quality isolate to anchor their daily target, it is hard to beat on price-to-protein.
