Your protein powder shouldn’t leave a weird aftertaste or make you second-guess what you just put in your body. Yet most protein powders on the market pack in sucralose, aspartame, or acesulfame potassium to keep the sugar count low while cranking up the sweetness. The result? A chalky, chemical flavor that lingers long after your shake is gone. Some people experience digestive upset from these additives. Others simply want cleaner ingredients that don’t come from a lab. Either way, you’re stuck reading nutrition labels and ingredient lists trying to find something that fits.

This guide breaks down 15 protein powders that skip the artificial sweeteners entirely. You’ll find options sweetened with monk fruit or organic coconut sugar, plus completely unflavored powders you can customize yourself. We cover both whey-based and plant-based proteins so you can choose what matches your dietary needs. Each pick includes details on the protein source, who benefits most from it, and key nutrition facts including price per serving. No fluff, no sponsored recommendations—just straightforward options that deliver clean protein without the synthetic stuff.
