FAQ

What counts as a “lowest sugar protein bars”?

Bars are ranked strictly by grams of total sugars per 100 g of product using the latest Open Food Facts records, so every entry you see is already computed from real lab-verified or label-verified nutrition data.

How do I tell if a bar is truly “no sugar”?

Check the per-100 g total sugars value in the leaderboard table; anything under 1 g is the closest you can get to “no sugar” with commercially available protein bars.

Can I make my own low-sugar protein bars at home?

A 2023 peer-reviewed study shows that combining whey protein isolate, almond butter, and a sugar-free sweetener such as allulose can achieve less than 1 g of total sugars per 100 g of homemade mixture.
