Unflavored protein powder is not automatically unsweetened

Different ingredients can serve different purposes

FDA describes flavors and sweeteners as separate ingredient categories. Other ingredients may help texture, mixing or stability without being the main protein source. [1]

Consequently, a short front-label description cannot identify every function in the formula. Read the ingredient list before treating unflavored as a complete composition statement. [1]

Use the attribute that actually matters to you

Someone avoiding a particular sweetener needs its ingredient identity, while someone comparing nutrient amounts needs the nutrition panel. These are related but different checks. [1]

An unsweetened preparation can still have the characteristic taste of its ingredients. This page does not rank sensory quality or assume that fewer ingredients automatically produces better health outcomes. [1]

Ask two separate questions

Imagine a powder has no added flavor but includes a sweetening ingredient. The lack of flavoring does not answer whether that sweetener is present.
