Best Protein Powder Without Added Sugar
Protein powders from the NIH Dietary Supplement Label Database whose labels list no added sugar, ranked by how completely the label discloses what is in the product.
Why People Avoid Added Sugar
Protein powders labeled for weight gain or as meal replacements often add sugar or maltodextrin to raise calories and improve taste. A scoop can carry 5 to 20 g of added sugar, which matters for diabetes, weight management, or anyone tracking carbohydrates.
This list removes labels that name cane sugar, sucrose, corn or tapioca syrup, honey, dextrose, fructose, or maltodextrin in their ingredients. Maltodextrin is not legally a sugar on the Nutrition Facts panel, but it raises blood glucose about as quickly as glucose, so it is excluded here.
Many of these products are sweetened with stevia, monk fruit, sucralose, or sugar alcohols instead, and the table notes which.
Results
1,531 of 2,413 on-market protein powder labels with an other-ingredients list name their protein source and list no sugar, syrup, honey, dextrose, fructose, or maltodextrin.
Ranked by label detail (stated amounts, named forms, a complete other-ingredients list), then by fewest other ingredients. The ranking reflects what the label discloses, not product testing, purity, or efficacy.

Search All Protein Powders
Open Supplement Search, choose the Protein Powder tab, and turn on the "Added sugar" chip under Exclude products containing. You can add "honey, syrup" under Must not contain. This page also requires a listed other-ingredients panel, since a label without one cannot show what it leaves out, so its count runs lower than the search page's.
