Leaving out maltitol or erythritol does not tell you how much sugar, fiber, or protein a bar contains. The ten bars here range from compact protein snacks to 330-calorie refrigerated bars, and they should not all be bought for the same job.
Promix Chocolate Chip Protein Puff Bar is our overall pick for 15 g protein in a 40 g bar. For a formula without glycerin as well as common sugar-alcohol sweeteners, RXBAR Chocolate Sea Salt is the simpler place to start.

Short on time? Choose Promix Chocolate Chip for a compact protein snack, CLIF Builders for 20 g protein, or ALOHA for a plant-based peanut butter option. Some bars here contain glycerin to retain moisture. If your avoidance list includes glycerin too, choose RXBAR, GoMacro, or G2G instead.
How We Chose
These exact flavors exclude common sugar-alcohol sweeteners, including erythritol, maltitol, sorbitol, xylitol, mannitol, isomalt, and lactitol. This is not a chemically polyol-free list: glycerin is present in several formulas and is identified below. We compared protein per bar, portion weight, sugar and fiber where appropriate, allergens, and storage demands. Scores reflect those editorial criteria, not a taste ranking or a prediction of digestive comfort. We favored a useful protein portion over an attractive low-sugar badge, while keeping higher-energy bars for people who need a larger snack. No bar qualifies merely because it says natural, keto, or no added sugar. Formulas differ by flavor, so the exact names matter.
Our Verdict
Promix Chocolate Chip Protein Puff Bar
15 g protein in a 40 g bar makes it a compact alternative to heavier nut-and-syrup bars.
Best for: People who tolerate milk and egg and want a compact protein snack
Check Price on AmazonOur Top Picks
Best Overall: Promix Chocolate Chip Protein Puff Bar
Promix Chocolate Chip Protein Puff Bars 12 pack
Best OverallA compact whey-based puff bar with 15 g protein, suited to a smaller snack rather than a large nut-butter energy bar.
Pros
- 15 g protein in a 40 g bar
- Whey-based protein puffs
- 12-bar package
Cons
- Contains glycerin and added fiber
- Contains milk and egg
Promix packs 15 g protein into a 40 g bar, so protein makes up 37.5% of its weight. The formula uses whey protein puffs, a marshmallow mixture, and chocolate chips. Glycerin, inulin, and tapioca fiber are present even though the common sugar-alcohol sweeteners are absent.
Skip this if you also avoid glycerin, milk, or egg. Compared with G2G’s 18 g protein in a 70 g bar, Promix is the smaller purchase by portion weight, with only 3 g less protein. It is the more focused protein snack; G2G makes more sense when you also want substantial food energy.
Best Plant-Based Peanut Butter Bar: ALOHA
ALOHA Peanut Butter Chocolate Chip Bars 12 pack
Best Plant-Based Peanut Butter BarA peanut-based bar with brown rice and pumpkin seed protein, giving 14 g protein and a substantial 10 g fiber portion.
Pros
- 14 g plant protein
- 10 g fiber per bar
- 5 g total sugar
Cons
- Contains peanuts and glycerin
- High fiber may not suit everyone
ALOHA Peanut Butter Chocolate Chip supplies 14 g protein, 240 calories, and 10 g fiber in a 56 g bar. Its protein blend uses brown rice and pumpkin seed protein, while peanuts make the allergen decision straightforward. Vegetable glycerin and monk fruit also appear in the formula.
Skip this if a large fiber portion is what you are trying to avoid. Sugar-alcohol-free is not the same as low-fiber. Compared with GoMacro’s 11 g protein in a 65 g bar, ALOHA gives you more protein in a lighter serving, but with a very different fiber profile.
Best Without Glycerin: RXBAR Chocolate Sea Salt
RXBAR Chocolate Sea Salt Bars 12 pack
Best Without GlycerinAn egg-white, date, and nut bar without glycerin, for buyers who want to exclude that ingredient as well as sugar-alcohol sweeteners.
Pros
- 12 g protein per bar
- No glycerin in this formula
- 0 g added sugar
Cons
- 14 g total sugar
- Contains egg, almonds, and cashews
RXBAR uses dates, egg whites, cashews, almonds, chocolate, cocoa, natural flavors, and sea salt. The current Chocolate Sea Salt panel lists 12 g protein, 200 calories, and 14 g total sugar, with zero added sugar. Dates still contribute sugar; zero added is not zero total.
Skip this if egg or tree nuts are a problem, or if you need a low-sugar bar. Compared with IQBAR’s 1 g sugar, RXBAR makes a very different nutritional trade. Choose RXBAR for the ingredient fit and absence of glycerin, not because its front-panel simplicity makes sugar irrelevant.
Best Larger Protein Portion: CLIF Builders
CLIF Builders Chocolatey Peanut Butter Bars 12 pack
Best Larger Protein PortionA full-size 20 g soy-protein bar for buyers who prioritize a larger protein portion over a low-sugar or minimal-ingredient formula.
Pros
- 20 g protein per bar
- Full-size 68 g portion
- Soy-based protein
Cons
- Contains soy, peanuts, and glycerin
- Not a low-sugar formula
Buy the full-size Chocolatey Peanut Butter Builders bar, not the mini or a different reduced-sugar range. The selected 68 g bar contains 20 g protein. Soy protein, syrups, sugar, peanuts, and vegetable glycerin make it a different proposition from a low-sugar diet bar.
Skip this if you exclude soy, peanuts, or glycerin. Compared with Promix, it adds 5 g protein but also 28 g of bar weight. It suits someone who wants the larger portion in one wrapper, rather than someone trying to keep their between-meal snack as small as possible.
Best Low-Sugar Option: IQBAR Chocolate Sea Salt
IQBAR Chocolate Sea Salt Bars 12 pack
Best Low-Sugar OptionA low-sugar pea-protein and almond bar with substantial added fiber and glycerin, rather than a promise of effortless digestion or better cognition.
Pros
- 12 g protein per bar
- 1 g total sugar
- 9 g fiber
Cons
- Contains glycerin and almonds
- Fiber blend may not suit sensitive digestion
IQBAR lists 12 g protein, 180 calories, 9 g fiber, and 1 g sugar per 45 g bar. Its panel separates 4 g organic glycerin from zero listed sugar alcohols. That distinction is exactly why a front-panel zero needs the full ingredient context.
Skip this if glycerin or a concentrated fiber blend is on your avoidance list. RXBAR removes glycerin but has 14 g sugar; neither is an automatic winner for everyone. IQBAR’s role here is a lower-sugar protein snack, not a treatment for appetite, cognition, or a digestive condition.
Best Substantial Refrigerated Snack: G2G
G2G Peanut Butter Chocolate Chip Bars 8 pack
Best Substantial Refrigerated SnackA larger peanut butter and whey bar with 18 g protein, for buyers who want a substantial refrigerated snack without glycerin.
Pros
- 18 g protein per bar
- No glycerin in this formula
- 300-calorie larger snack
Cons
- Requires attention to refrigerated storage
- Contains peanuts and milk
G2G’s 70 g Peanut Butter Chocolate Chip bar contains 18 g protein and 300 calories. Honey, brown rice syrup, and chocolate contribute to its 13 g total sugar, including 11 g added. It is food for a larger energy gap, not a small protein supplement disguised as a bar.
Skip this if you cannot follow the package’s refrigeration and storage directions. Compared with Perfect Bar’s 330 calories and 15 g protein, G2G gives you more protein with slightly less energy. Both demand more storage planning than a shelf-stable RXBAR or GoMacro.
Best Almond-and-Honey Option: Rise
Rise Almond Honey Protein Bars 12 pack
Best Almond-and-Honey OptionThe current four-ingredient almond, honey, whey, and coconut glycerin formula supplies 16 g protein, rather than the older 20 g version.
Pros
- 16 g protein per bar
- Four named ingredients
- 60 g serving
Cons
- 15 g added sugar
- Contains milk, almonds, and glycerin
The current Almond Honey formula is four ingredients: almonds, honey, whey isolate, and coconut glycerin. Its 60 g bar lists 16 g protein, 280 calories, and 16 g total sugar, including 15 g added. Use those numbers rather than assuming an older 20 g wrapper describes today’s formula.
Skip this if you are trying to minimize added sugar or exclude glycerin. Compared with G2G, Rise is a smaller bar with 2 g less protein, but its four-ingredient formula is easier to compare ingredient by ingredient. Short does not mean sugar-free, and honey still counts as added sugar.
Best Glycerin-Free Plant Option: GoMacro
GoMacro Coconut Almond Butter Chocolate Chips MacroBars 12 pack
Best Glycerin-Free Plant OptionA brown-rice and pea-protein bar without glycerin, suited to a larger plant-based snack rather than maximizing protein per calorie.
Pros
- 11 g plant protein
- No glycerin in this formula
- 65 g substantial portion
Cons
- 270 calories for 11 g protein
- Contains almonds
GoMacro Coconut Almond Butter Chocolate Chips combines a sprouted brown rice and pea protein blend with brown rice syrup, almond butter, coconut, and chocolate chips. The 65 g bar supplies 11 g protein and 270 calories. Those numbers make its role clear: an energy-containing snack with some protein.
Skip this if your main goal is maximum protein in minimum food energy. ALOHA supplies 3 g more protein at 240 calories, while CLIF Builders reaches 20 g protein. GoMacro is the plant-based choice here when avoiding glycerin matters more than protein density.
Best Higher-Calorie Option: Perfect Bar
Perfect Bar Dark Chocolate Chip Peanut Butter 20 bars
Best Higher-Calorie OptionA refrigerated peanut butter bar for people who need a higher-calorie snack, not buyers looking for the leanest way to add protein.
Pros
- 330 calories per bar
- 15 g protein
- No common sugar-alcohol sweeteners
Cons
- Refrigerated storage
- Peanut, milk, egg, and sesame ingredients
Perfect Bar Dark Chocolate Chip Peanut Butter contains 15 g protein and 330 calories per 65 g bar, with 18 g sugar, including 12 g added. The selected listing is two ten-count packs. Peanut butter, honey, milk powder, egg powder, and sesame oil make its ingredient fit more important than a generic health halo.
Skip this if you need a low-calorie snack or cannot meet the storage directions. Promix supplies the same 15 g protein in a 40 g bar; Perfect Bar is the choice when more energy is useful. Neither the whole-food powders nor the refrigerated format makes it a complete meal.
Best Chocolate Pretzel Option: NuGo Dark
NuGo Dark Chocolate Pretzel Sea Salt Bars 24 count
Best Chocolate Pretzel OptionA soy-protein chocolate pretzel bar with 12 g protein, for buyers who accept added sugar and do not need milk-allergy assurance.
Pros
- 12 g protein per bar
- 200 calories per 50 g bar
- No glycerin in this formula
Cons
- Contains soy and 12 g added sugar
- Not a milk-allergy recommendation
NuGo Dark Chocolate Pretzel Sea Salt lists 12 g protein, 200 calories, and 14 g total sugar per 50 g bar, including 12 g added. It uses soy protein, syrups, sugar, and acacia gum; sugar-alcohol-free does not make it gum-free or soy-free.
Skip this if milk allergy is part of your decision. An FDA-posted recall named specific lots with December 2025 best-by dates for undeclared milk. Check lot details, not just vegan wording. Compared with RXBAR, this has the same labeled protein but uses soy rather than egg.

How to Choose a Bar Without Sugar-Alcohol Sweeteners
Decide whether you also exclude glycerin
In food labeling, a bar can list zero sugar alcohols while still containing glycerin, a chemically related polyol used to retain moisture. Promix, ALOHA, CLIF Builders, IQBAR, and Rise contain glycerin. If your own avoidance rule includes it, do not buy those just because of the article title. RXBAR, GoMacro, G2G, and the selected NuGo formula do not list it. Read the current wrapper because a different flavor can change the answer.
Choose protein, energy, and fiber separately
Promix’s 15 g protein in 40 g of food and GoMacro’s 11 g in 65 g are different snacks. Perfect Bar’s 330 calories may help someone who struggles to eat enough, while being the wrong purchase for someone who wants a small addition between meals. ALOHA and IQBAR bring 10 g and 9 g fiber respectively. Those are substantial amounts in one sitting, not automatically a digestive advantage.
Read total sugar and added sugar
RXBAR’s zero added sugar coexists with 14 g total sugar. Rise’s honey contributes to 15 g added sugar. Neither fact requires moral language about good or bad food, but both matter for planning. The FDA label guide explains the distinction. If you need carbohydrate counting for a medical condition, use the full current label and your care plan, not an informal net-carb calculation on the front.
Do not promise a symptom-free bar
The FDA’s sugar-alcohol guide discusses possible gastrointestinal effects, but removing those sweeteners does not remove every potential trigger. Inulin, other added fibers, portion size, and allergies can matter too. ALOHA is not a low-fiber alternative to an erythritol bar. If symptoms persist, investigate them with a clinician rather than assuming one ingredient explains every episode.
Calculate cost for the job the bar will do
Divide the delivered price by the actual bar count first: the listings here include eight, twelve, twenty, and twenty-four bars. Then compare cost per 15 g protein if protein is the main job. A lower cost per bar can disappear when the bar contains less protein. For a substantial snack, calories and storage may deserve equal weight. G2G and Perfect Bar require a refrigerator plan; avoid bulk buying before you know that plan works.
Bars are convenience food, not a requirement for muscle growth. The ISSN protein position stand emphasizes adequate total protein for exercising adults. Count meals and snacks together. Our low-carb protein powder comparison is useful when a shake fits your numbers better, while the stevia-free powder guide addresses a different sweetener preference.
Frequently Asked Questions
Does no sugar alcohols mean no sugar?
No. A bar can use dates, honey, rice syrup, or cane sugar instead. Rise Almond Honey has 16 g total sugar in the selected formula, while IQBAR Chocolate Sea Salt has 1 g. Both exclude the common sugar-alcohol sweeteners. Decide whether your priority is the sweetener type, total sugar, or both.
Why is glycerin still in some of these bars?
It helps retain moisture and is treated differently from common sugar-alcohol sweeteners on many nutrition panels. Chemically, glycerin is a polyol, so a strict all-polyol exclusion is narrower than this list. If that describes your needs, start with RXBAR, GoMacro, or G2G and confirm the wrapper rather than relying on a zero claim.
Which bar has the most protein?
CLIF Builders Chocolatey Peanut Butter has 20 g per full-size bar, followed by G2G at 18 g and the current Rise Almond Honey at 16 g. Portion sizes differ. Promix has 15 g in a smaller 40 g bar, so the highest absolute protein amount is not necessarily the best fit for a compact snack.
Will these bars prevent bloating?
No bar can guarantee that. Some people avoid certain sugar alcohols, but several selections still contain added fiber or glycerin. Others contain milk, nuts, egg, or soy. Choose according to your actual needs, avoid a known allergen, and seek medical advice for persistent symptoms. A new wrapper is not a diagnosis.
Can I use a bar instead of a post-workout shake?
Yes, if it helps meet your food and protein needs, but compare the amount rather than assuming one bar equals one scoop. RXBAR and IQBAR provide 12 g, while many shakes supply 24-30 g. Pair a smaller bar with another protein food when needed. Our sensitive-stomach powder guide compares other options.
Bottom Line
Promix Chocolate Chip is our pick for a compact 15 g protein snack, provided milk, egg, glycerin, and added fiber fit your needs. Choose RXBAR if glycerin is also excluded, CLIF Builders for a larger protein portion, or ALOHA for a plant-based peanut butter bar. Higher-calorie G2G and Perfect Bar solve a different problem and need refrigeration planning. Read the exact flavor and package count before checkout; the absence of one sweetener is only the beginning of the decision.
