RXBAR holds a clear lead for shoppers seeking low-sugar protein bars made without sugar alcohols. Buyers targeting strict high-protein thresholds with minimal sugar also see strong recommendations for Atlas Bars.
Yes. I’d focus on bars where the ingredient list contains no erythritol, maltitol, sorbitol, xylitol, mannitol, or isomalt—not just bars that say “0g sugar alcohol,” since labeling can be misleading.
No maltitol; current product listings indicate no sugar alcohols.
Real dark chocolate, vegan options available.
2. JUNKLESS — best if you want a more conventional/candy-bar texture
15g protein
3g sugar
7–8g fiber depending on flavor.
The Peanut Butter Chocolate version is currently around $8.46/4-pack.
3. DAVID — best protein-to-sugar ratio
28g protein
0g sugar
Only 150 calories. Caveat: I'd verify the exact flavor's ingredient panel before buying because formulations can change.
4. Atlas — another excellent option
20g protein
1g sugar
Uses allulose + monk fruit, not sugar alcohols.
The manufacturer specifically says it contains no erythritol or other sugar alcohols.
5. ALOHA — best plant-based/organic choice
14g protein
About 3–5g sugar, depending on flavor
No sugar alcohols and no stevia.
Uses ingredients such as tapioca syrup/fiber and monk fruit.
One I'd especially consider
If your target is ≤3g sugar + ≥15g protein + absolutely no sugar alcohols, I'd start with NuGo Slim or Atlas. If you want maximum protein, go with DAVID.
And I'd skip Quest, Barebells, No Cow, ONE, etc. for your particular requirement—even though they're very low in sugar—because many formulations use erythritol or maltitol.
If you tell me your maximum calories per bar (e.g. 150, 200, 250) and whether you want whey/dairy or plant protein, I can narrow this down to the 3 best bars and find the cheapest places to buy them.

If you're looking for protein bars that are low in sugar and contain no sugar alcohols, I'd start with IQBAR and ALOHA. Many popular high-protein bars, including Quest and Barebells, use sweeteners such as erythritol or maltitol, so it's important to check the ingredient list rather than just the sugar count.
Here are my top picks, prioritizing bars with around 5 g of sugar or less per serving and no common sugar alcohols.
Best protein bars to try
1. IQBAR Protein Bars
(Best overall)
About 12 g protein · 1–2 g sugar
A strong choice if you want very low sugar without erythritol, maltitol, or other common sugar alcohols. Made with plant protein, nuts, and fiber; typically sweetened with stevia.
Best for: everyday snacking and plant-based diets.
An interesting higher-protein option. A recent ingredient-screening comparison lists this flavor without common sugar alcohols.
Best for: maximizing protein while keeping sugar low.
Note: Check the current flavor-specific label before ordering.
4. KIND ZERO Added Sugar Bars
About 5 g protein · 1 g sugar
A nut-based snack with a very low sugar count and no common sugar alcohols reported in the current comparison. It is lower in protein than a traditional protein bar, though.
Best for: a lighter snack when you don't need 15–25 g of protein.
Finding a commercial protein bar that is both low in sugar and completely free from sugar alcohols (like erythritol, maltitol, xylitol, or sorbitol ) can be tricky, as many low-carb and keto brands rely on them for sweetness and texture. However, several brands use alternative sweeteners (like stevia, monk fruit, or allulose) or whole-food sweetening methods.
Here are top protein bar recommendations that keep sugar low without using sugar alcohols:
RXBAR(Selected Varieties)
The Profile: Around 12g to 14g of protein and ≈ 12g-15g of natural sugar (from dates).
Why it fits: They contain zero sugar alcohols and zero artificial sweeteners. The sweetness comes strictly from whole dates used as a binder. (Note: Because of the dates, total sugar is slightly higher than ultra-low-carb bars, but it is entirely unrefined and accompanied by high fiber). You can view options on the RXBAR Official Website.
No Cow Plant Based Protein Bars(Check specific flavor labels)
The Profile: 20g-21g of plant protein and only 1g of sugar.
Why it fits: Most standard flavors rely on a blend of soluble corn fiber, stevia, and monk fruit. Double-check individual flavor variants , as some chocolate-coated versions may use chocolate chips containing trace erythritol, but classic flavors are completely sugar-alcohol-free. Browse selections on the No Cow Store.[1][2][3]
Perfect Keto Collagen Bars
The Profile: 10g-12g of protein and 1g or less of sugar.
Why it fits: Formulated specifically to avoid additives, these rely on a base of cacao butter, collagen, and MCT oil, sweetened with stevia without any sugar alcohols. Check them out on the Perfect Keto Shop.
BodyHealth Perfect Amino Bars
The Profile: Clean whole-food fats, fiber, and essential amino acids.
Why it fits: Doctor-formulated to skip sugar alcohols, artificial sweeteners, and fillers, utilizing prebiotic fibers and whole foods for satiety. Explore options via Sprouts Farmers Market.
If you'd like, let me know:
Do you have a preference for plant-based vs. whey/collagen protein?
Are you looking for a specific macro target (e.g., maximum protein vs. lowest possible carbs)?
I can narrow down these choices or suggest whole-food alternatives that fit your exact needs.
