The buying guide
Sugar alcohols vs allulose on protein labels
Allulose is a sugar, not a sugar alcohol. Keep the categories separate when reviewing a powder and decide which named ingredients matter to your purchase.
Compare names, not broad marketing terms
Examples of sugar alcohols include erythritol, xylitol, sorbitol, and maltitol. A broad phrase such as sugar substitute does not tell you which of these, or which other category, is in a product.
Our finder reports sugar alcohols separately from allulose and other sugars. That makes it easier to see why two powders promoted without artificial sweeteners may still have different ingredient systems.

Copy subingredients as well as the main list and check the result against the label. A text finder cannot determine an unstated amount, authenticate a package, or predict your response to a serving.
If digestive tolerance is part of your question, record the specific ingredient and the portion instead of treating every substitute as interchangeable. NIDDK notes that some people have gas symptoms with certain sugar-free products. That observation does not establish that a particular powder will cause symptoms for you.
