Zero sugar on a protein tub does not tell you which sweeteners are inside. Erythritol, sorbitol and maltitol are sugar alcohols; sucralose, stevia and monk fruit are different ingredients. These ten powders leave sugar alcohols out of the selected recipes, with both sweetened and unsweetened choices.
Written by Tom Miller, CSCS. Updated: October 2026.
Short on time? Naked Whey Unflavored is our overall pick for its single-ingredient recipe and 25g protein portion. NOW Sports Pea Protein is the unsweetened plant alternative. Dymatize ISO100 Gourmet Chocolate suits buyers who want a flavored isolate and accept sucralose and stevia. Leaving out sugar alcohols does not guarantee freedom from bloating, lactose symptoms or food allergies.
How We Chose
We compared complete ingredient lists for the selected flavor, protein source, protein grams, powder portion, calories and package supply. Recipes listing erythritol, xylitol, sorbitol, maltitol or other sugar-alcohol ingredients did not qualify. We also checked sweetener blends rather than treating a monk-fruit or zero-sugar front label as sufficient. Our scores favor a useful protein portion and a clear reason to choose the formula, such as an unsweetened recipe, dairy exclusion or a flavored isolate. They do not claim one sweetener is healthier or one brand produces more muscle. A scoop is not a standardized unit: Premier’s 30g protein portion uses two scoops, while several others use one. Flavor changes require another ingredient check.
Our Verdict
Naked Whey Unflavored
One ingredient and 25g protein per labeled portion make Naked Whey the clearest starting point when you want neither sugar alcohols nor other sweeteners.
Best for: Adults who tolerate dairy and want an unsweetened whey concentrate
Check Price on AmazonOur Top Picks
Best Overall: Naked Whey Unflavored
Naked Whey Unflavored 2lb
Best OverallAn unsweetened whey concentrate with one ingredient, 25g protein and 120 calories per 30g portion, in the selected two-pound tub.
Pros
- One ingredient: whey protein concentrate
- 25g protein and 120 calories
- No added sweetener
Cons
- Contains milk and naturally occurring lactose
- Unflavored rather than chocolate or vanilla
Naked Whey lists whey protein concentrate as its only ingredient. A 30g portion supplies 25g protein, 120 calories and 2g sugar. That sugar is not an added sugar alcohol; the formula still contains milk-derived components, including lactose.
It suits smoothies and recipes when you want to control sweetness yourself. Compared with Dymatize ISO100, you give up a flavored isolate formula for the shorter ingredient list. Skip this if you have a milk allergy or need a low-lactose option. Unflavored also does not mean flavorless, so choose a flavored powder below if you want a finished chocolate shake without adding other ingredients.
Best Monk-Fruit Plant Blend: Truvani Vanilla
Truvani Vanilla Plant Protein 18 Servings
Best Monk-Fruit Plant BlendA five-ingredient vanilla blend of pea, pumpkin seed and chia proteins, sweetened with monk fruit, in the selected eighteen-serving bag.
Pros
- 20g plant protein
- Five listed ingredients
- No stevia or sugar alcohols
Cons
- Only 18 servings in the selected bag
- Less protein per portion than Premier
The selected Truvani Vanilla bag lists 20g protein and 130 calories per 29g scoop. Its five ingredients are pea protein, vanilla powder, pumpkin seed, monk fruit extract and chia seed protein. That is a different sweetener approach from the sucralose-based flavored whey options.
Check the package count when comparing value: this listing contains 18 servings, not the 20-serving bags sold elsewhere. NOW Pea gives you an unsweetened plant alternative without vanilla or monk fruit. Skip this if you want no sweetener at all or prefer a larger first purchase. A short recipe can simplify ingredient selection, but it cannot guarantee digestive comfort.
Best Larger Protein Portion: Premier Protein Chocolate
Premier Protein Chocolate Milkshake Powder 17 Servings
Best Larger Protein PortionA chocolate whey blend with 30g protein and 150 calories per two-scoop serving, using sucralose and acesulfame potassium rather than sugar alcohols.
Pros
- 30g whey protein per portion
- 150 calories
- Seventeen full portions per tub
Cons
- A serving requires two scoops
- Contains sucralose, acesulfame potassium and milk
Premier’s current Chocolate Milkshake panel defines a serving as two scoops, or 41g powder. That portion supplies 30g protein and 150 calories. One scoop is not the full 30g protein serving, and the selected tub contains 17 full portions.
The recipe combines whey isolate and concentrate with soluble corn fiber, xanthan gum, sucralose and acesulfame potassium. Choose it for the larger protein portion, not an additive-free recipe. Naked Whey has fewer ingredients; Premier has 5g more protein per labeled portion. Skip this if you avoid milk, artificial sweeteners or added fiber. Removing sugar alcohols does not remove those separate considerations.
Best Coconut-Sugar Plant Powder: Orgain Simple Chocolate
Orgain Simple Creamy Chocolate Protein 1.25lb
Best Coconut-Sugar Plant PowderA chocolate plant-protein blend sweetened with coconut sugar, supplying 20g protein per two-scoop portion without erythritol or stevia in the selected recipe.
Pros
- 20g plant protein
- Coconut sugar instead of erythritol
- No stevia in the selected recipe
Cons
- Contains peanuts, almonds and coconut
- Two scoops per serving; about 14 servings
Orgain Simple is the important distinction here. Its Creamy Chocolate recipe uses coconut sugar and a blend that includes pea, brown rice, peanut, pumpkin seed, almond and chia ingredients. The label lists 20g protein, 150 calories and 3g total sugar per 40g portion.
The 1.25lb tub contains about 14 two-scoop servings. Truvani supplies a smaller 29g powder portion and uses monk fruit instead of coconut sugar. Skip this if you avoid peanuts or almonds, or want an unsweetened powder. Do not assume another Orgain product qualifies: the brand sells different recipes with different sweeteners, including products containing erythritol.
Best Standard Whey Blend: Optimum Nutrition Gold Standard
ON Gold Standard Whey Double Rich Chocolate 2lb
Best Standard Whey BlendThe selected Double Rich Chocolate whey blend supplies 24g protein per 31g scoop and uses acesulfame potassium, without listed sugar alcohols.
Pros
- 24g protein per 31g portion
- 29 servings in the selected tub
- No listed sugar alcohols
Cons
- Contains milk and soy
- Includes acesulfame potassium
The U.S. Double Rich Chocolate panel lists 24g protein and 120 calories per 31g scoop, with 29 servings in this tub. Its whey blend includes isolate, concentrate and hydrolyzed whey. Acesulfame potassium appears in the ingredient list; it is not a sugar alcohol.
This is a middle ground between unsweetened Naked Whey and an all-isolate formula such as ISO100. It still contains milk and soy, so it does not answer either allergy exclusion. Skip this if you need a milk-free or soy-ingredient-free powder, or want no high-intensity sweetener. Check the exact flavor because the sweetener recipe can differ across the Gold Standard range.
Best Flavored Whey Isolate: Dymatize ISO100 Gourmet Chocolate
Dymatize ISO100 Gourmet Chocolate 20 Servings
Best Flavored Whey IsolateA twenty-serving chocolate whey-isolate powder with 25g protein and 120 calories per scoop, sweetened with sucralose and stevia rather than sugar alcohols.
Pros
- 25g protein per scoop
- 120 calories and 1g sugar
- Hydrolyzed and non-hydrolyzed whey isolates
Cons
- Contains milk and soy
- Uses both sucralose and stevia
ISO100 Gourmet Chocolate combines hydrolyzed whey isolate with whey isolate. One 32g scoop supplies 25g protein, 120 calories and 1g sugar. The complete recipe includes sucralose and steviol glycosides, which qualify for this sugar-alcohol exclusion but not a stevia-free one.
Choose it when you prefer an isolate-based chocolate powder over the concentrate in Naked Whey. Isolate processing reduces lactose relative to concentrate, but this is still a milk product and not a milk-allergy solution. Skip this if you avoid soy lecithin, stevia or sucralose. Ascent is the simpler unsweetened whey alternative when flavoring is optional.
Best Stevia-Sweetened Isolate: Legion Whey+ Dutch Chocolate
Legion Whey+ Dutch Chocolate 30 Servings
Best Stevia-Sweetened IsolateA thirty-serving Dutch Chocolate whey-isolate powder with 22g protein per portion, stevia sweetness and added gums, without listed sugar alcohols.
Pros
- 22g protein per portion
- 30 labeled servings
- Stevia rather than sugar alcohol sweeteners
Cons
- Contains milk; listing also declares soy
- Includes gums and natural flavor
Legion’s selected Dutch Chocolate label lists 22g protein per 28g portion. The recipe includes stevia, cocoa, natural flavor, xanthan gum and sunflower lecithin. Sugar-alcohol avoidance therefore does not make it an unflavored or gum-free powder.
It contains less protein per labeled portion than ISO100’s 25g, so compare equal protein amounts when judging checkout value. The exact listing declares milk and soy; keep that warning in your decision even if an ingredient image shows sunflower lecithin. Skip this if you avoid stevia, gums or those allergens. NOW Pea is the straightforward milk-free, unsweetened option in this group.
Best Unsweetened Whey Blend: Ascent Unflavored
Ascent Unflavored 100% Whey Protein 2lb
Best Unsweetened Whey BlendAn unflavored whey-isolate-and-concentrate blend with sunflower lecithin, supplying 25g protein per scoop without added sweeteners in a two-pound bag.
Pros
- 25g protein and 120 calories
- No added sweetener
- Thirty labeled servings
Cons
- Contains milk
- Includes concentrate and sunflower lecithin
Ascent’s unflavored formula combines native whey isolate, whey isolate, whey concentrate and sunflower lecithin. One 31g scoop supplies 25g protein and 120 calories. The selected two-pound bag lists 30 servings.
It matches Naked Whey’s headline protein and calorie numbers but uses a blend rather than a single concentrate ingredient. Ascent also publishes Informed Sport information; athletes should check the current exact product and batch with the certifier. Skip this if you need dairy-free protein or want a single-ingredient recipe. The inclusion of isolate does not make this a pure isolate powder, and it does not erase the concentrate or milk allergen.
Best Unsweetened Plant Powder: NOW Sports Pea Protein
NOW Sports Pea Protein Unflavored 2lb
Best Unsweetened Plant PowderA single-ingredient yellow pea protein isolate with 24g protein per 33g scoop, without added sweeteners, sold in the selected two-pound bottle.
Pros
- One ingredient: yellow pea protein isolate
- 24g protein per scoop
- No sweetener or flavoring
Cons
- Unflavored pea protein still has its own taste
- Not suitable for a pea allergy
NOW uses yellow pea protein isolate without a sweetener blend. A 33g scoop supplies 24g protein and 120 calories. That gives you 4g more protein per labeled portion than Truvani, without its vanilla or monk fruit.
This is the plant option when the shortest ingredient list matters more than a finished shake flavor. The brand publishes Informed Sport information, which athletes should verify for the current product and batch. Skip this if you have a pea allergy or want a chocolate shake without adding other ingredients. A milk-free recipe also does not establish that any powder will resolve digestive symptoms.
Best Dairy-Free Animal Protein: Equip Prime Chocolate
Equip Prime Protein Chocolate 30 Scoops
Best Dairy-Free Animal ProteinA dairy-free chocolate beef-protein powder with 21g protein per scoop, cocoa and stevia, distinct from the brand's coconut-sugar and monk-fruit version.
Pros
- 21g beef-derived protein
- No milk ingredients
- Three-ingredient chocolate recipe
Cons
- Not vegan
- Do not assume whey-equivalent amino acid proportions
This selected Chocolate version lists grass-fed beef protein, cocoa powder and stevia leaf extract. One scoop supplies 21g protein. The brand also sells a separate low-sugar Chocolate version with different sweeteners; do not transfer its ingredient list to this bag.
Equip is a niche alternative when you want animal-derived protein without dairy. The listing discusses naturally occurring collagen, so total protein grams alone do not establish the same amino acid proportions as whey. Skip this if your priority is the clearest whey-style muscle-building protein comparison, or if you avoid stevia. NOW Pea is the simpler dairy-free alternative with a different protein source.

Buying Guide
Read the Sweetener Names, Not Just Zero Sugar
Check for erythritol, xylitol, sorbitol, maltitol, mannitol, isomalt and lactitol. A monk-fruit product can use a blended sweetener containing erythritol, so the full ingredient list matters. The FDA distinguishes sugar alcohols from high-intensity sweeteners. Sucralose and acesulfame potassium are not sugar alcohols. Neither are stevia and monk fruit.
Allulose is a rare sugar, not a sugar alcohol. Coconut sugar is still sugar. Those distinctions help you choose a recipe, but they do not rank ingredients as good or bad. Pick Naked Whey or NOW Pea for no added sweetener; choose Truvani for monk fruit, Orgain Simple for coconut sugar, or ISO100 if sucralose and stevia fit your preferences.
Match the Protein Source to Your Other Restrictions
Leaving out sugar alcohols does not remove lactose, milk protein, soy, nuts, gums or added fiber. Naked Whey is concentrate and contains lactose. Dymatize uses isolates but still declares milk and soy. Orgain Simple contains peanuts and almonds. Equip avoids dairy but contains beef protein and stevia.
For separate exclusions, compare our protein powders without stevia, powders without soy ingredients and gum-free protein powders. Each filter answers a different question. A powder that qualifies for one can fail another, even within the same brand.
Compare Protein Portions and Delivered Cost
Premier supplies 30g protein from two scoops; Naked Whey supplies 25g from about two smaller scoops; NOW supplies 24g from one 33g scoop. Weigh the labeled powder amount rather than swapping scoops between tubs. The protein number measures the nutrient, not the weight of the powder you pour.
Use delivered price divided by servings, then adjust for protein grams. For example, a $30 tub with 20 servings costs $1.50 per serving. If each portion contains 20g protein, the cost per 25g protein is about $1.88. These are calculation examples, not current prices. Check the selected size: Truvani is 18 servings here, Premier 17 and Ascent 30. More servings can reflect smaller portions rather than more protein.
Use the Powder to Fill a Dietary Gap
The ISSN protein position stand places total dietary protein and suitable portions within a training program. Powder is a convenient food supplement, not a substitute for progressive training, enough calories and varied meals. A larger scoop does not automatically create a better result.
MedlinePlus notes that large sugar-alcohol intakes can cause gastrointestinal symptoms. Persistent symptoms still deserve a proper assessment instead of an expanding list of exclusions. Try one appropriate recipe at a time, follow the label and seek medical advice for persistent diarrhea, pain or suspected allergy. Discuss protein targets with your clinician if you have kidney disease or another condition affecting protein needs.
Frequently Asked Questions
Is Sugar-Alcohol-Free the Same as Sugar-Free?
No. Orgain Simple uses coconut sugar and qualifies for this list because its selected recipe does not list sugar alcohols. Conversely, a sugar-free powder may use erythritol. Naked Whey has naturally occurring milk sugar despite having no added sweetener. Read the nutrition panel for sugar grams and the complete ingredients for the type of sweetener.
Do Sucralose and Stevia Count as Sugar Alcohols?
No. They are different kinds of sweeteners. The same applies to acesulfame potassium and monk fruit. A finished sweetener blend can still include erythritol or another sugar alcohol, which is why the entire recipe matters. ISO100 uses sucralose and stevia; Truvani uses monk fruit. Those formulas fit this exclusion without being unsweetened products.
Will These Powders Prevent Bloating?
No recipe can guarantee that. Lactose, milk allergy, pea sensitivity, concentrated fiber, portion size and other dietary factors can matter even without sugar alcohols. Premier contains soluble corn fiber and gums, while Naked Whey contains concentrate. Choose around restrictions you understand, and get persistent or severe symptoms assessed rather than assuming a single ingredient explains everything.
Which Options Have No Added Sweeteners?
Naked Whey Unflavored, Ascent Unflavored and NOW Sports Pea Protein have no added sweeteners in the selected recipes. Naked is a single-ingredient whey concentrate; Ascent combines whey forms with sunflower lecithin; NOW uses yellow pea protein isolate. Unflavored does not mean tasteless. Use the protein source and your other dietary restrictions to narrow those three.
Can I Use These Powders for Muscle Gain?
They can help you meet a protein target alongside resistance training and sufficient food. Leaving out sugar alcohols does not give a powder an additional muscle-building effect. Compare protein grams, source, total intake and tolerability. For a plain isolate specifically, our unflavored whey-isolate guide narrows the choice further than this mixed dairy-and-plant list.
Bottom Line
Naked Whey Unflavored wins for a clear reason: one ingredient, no added sweetener and 25g protein per labeled portion. NOW Sports Pea is the unsweetened plant alternative; ISO100 Gourmet Chocolate is the flavored isolate pick when sucralose and stevia suit you. Compare the complete recipe, not just the sugar line, and price equal protein amounts. For another specific exclusion, use our gum-free protein powder guide. Change the formula to fit your needs, without assuming any ingredient exclusion guarantees digestive comfort.
