Two different shopping goals
A formula without artificial sweeteners may still be sweetened. If you want to avoid a particular ingredient, look for that ingredient. If you want no added sweetness, compare unsweetened versions instead. Conflating those goals can lead to buying a product that meets its claim but not your preference.
Use a version-specific ingredient check
Write down the names of sweeteners from the exact flavor label. Do not infer them from sugar grams alone. Keep sugar alcohols as a separate question: a powder can avoid one sweetener class while using another.
A brand promise is a starting point
Legion describes Whey+ as naturally sweetened, and directs readers to individual flavor labels. That can help identify which label to inspect; it is not a reason to copy a family-wide ingredient list into every variant. The same rule applies when a brand changes a flavor or reformulates.
Do not turn preference into a health verdict
This guide is for matching an ingredient preference. It does not rank the safety of all sweeteners or imply that a naturally sourced alternative will suit every stomach. For symptoms or a medically directed restriction, get advice appropriate to the actual concern.
Keep the shortlist small enough to verify
Choose a few formulas and compare their current labels side by side. Our source and ingredient guides help you avoid changing the protein source, sweetener and other additions all at once without noticing.
