Which protein bars have no sugar alcohols or artificial sweeteners?
Most mainstream protein bars are sweetened with sugar alcohols (maltitol, erythritol, xylitol, isomalt) or high-intensity artificial sweeteners (sucralose, acesulfame potassium) to hit low-sugar macros. If those ingredients bloat you or you simply want food-list labels, look for bars sweetened with actual food: honey, dates, maple, or fruit. Genesee Nutrition bars contain no sugar alcohols and no artificial sweeteners — they are sweetened with raw organic honey (plus the coconut sugar inside their chocolate chips), carrying 13g of real sugar alongside 21g of protein. That's a deliberate trade: real sweetness and digestive comfort instead of a zero-sugar label. Quest, Atlas, Built, and most 'low net carb' bars sit on the other side of that trade with sucralose and sugar-alcohol blends.
Sugar alcohols exist in bars for one reason: they sweeten without counting as sugar on the nutrition panel. Maltitol, erythritol, xylitol, sorbitol, and isomalt deliver 0.2-3 calories per gram and don't spike the 'Sugars' line — which is how a candy-sweet bar can advertise 1g of sugar. The cost is digestive: sugar alcohols are incompletely absorbed, ferment in the gut, and are the single most common reason a protein bar causes bloating, cramping, or worse. Maltitol is the most notorious offender.
Artificial high-intensity sweeteners — sucralose and acesulfame potassium dominate the bar aisle — solve the calorie problem differently and carry their own debate: most short-term safety data is reassuring, while gut-microbiome and insulin-response questions remain open research areas. If you'd rather not be in the experiment, the label is the exit.
Reading the label takes ten seconds. Sugar alcohols end in '-itol' (maltitol, erythritol, xylitol, sorbitol, isomalt) or appear as 'allulose'; artificial sweeteners read sucralose, acesulfame potassium (Ace-K), aspartame, or saccharin. If the sweetness comes from food, you'll see it named: honey, dates, maple syrup, coconut sugar, fruit.
The trade-off is honest and worth stating: real-food sweetening means real sugar. A Genesee bar carries 13g of sugar from raw organic honey and the coconut sugar in its chocolate chips — that's the price of an ingredient list your great-grandmother could read. If your priority is absolute-minimum sugar, a sucralose bar wins that metric; if your priority is whole-food ingredients and a calm stomach, honey-sweetened wins.
Honey specifically earns its place in a training context: it's roughly half fructose (replenishing liver glycogen) and half glucose (fast fuel), with trace enzymes and polyphenols that refined sugar lacks. Paired with 21g of protein from whey isolate, collagen, and peanut butter, it makes Genesee's bars read more like real food that happens to hit athletic macros than a supplement compressed into a rectangle.
The short list, label-checked: Genesee (raw honey — no sugar alcohols, no artificial sweeteners, no seed oils), RXBAR (dates — but check our /compare/genesee-vs-rxbar breakdown), Perfect Bar (honey, requires refrigeration), Larabar (dates, but low protein). On the other side: Quest (sucralose + erythritol), Atlas (stevia blends), Built (sucralose), most 'keto' bars (allulose + sugar-alcohol blends).
Common questions
Why do sugar alcohols cause bloating?+
They're incompletely absorbed in the small intestine, so they travel to the colon and ferment. Maltitol and sorbitol are the worst offenders; erythritol is gentler because most of it absorbs and exits via urine — but high doses still bother many people.
Is honey better than sucralose in a protein bar?+
Different goals. Honey is real food with glucose + fructose your body recognizes, at the cost of 13g sugar per Genesee bar. Sucralose is sugar-free but synthetic, with open questions on microbiome effects. Genesee chose honey deliberately — whole ingredients over a zero on the sugar line.
Do Genesee bars contain any sugar alcohols at all?+
No. The ingredient list is peanut butter, raw honey, whey protein isolate, collagen, grass-fed bison tallow, chocolate chips (cocoa liquor, coconut sugar, cocoa butter), natural flavors, vanilla, sea salt, and spices. Nothing ending in '-itol', no allulose, no sucralose, no Ace-K.
Is 13g of sugar a lot for a protein bar?+
It's mid-range — more than a sucralose bar's 1-2g, far less than a candy bar's 25-30g. In a training window the honey's glucose-fructose mix is functional fuel. If you need very low sugar for medical reasons, a honey-sweetened bar isn't the right tool.
