10 Best Protein Powders Without Gums of 2026

A protein powder can leave out xanthan gum and still contain guar gum, acacia gum, or carrageenan. The useful question is not whether the front says simple ingredients, but which ingredients are actually in your chosen flavor.

Our pick is Naked Whey Unflavored: one ingredient, 25 g protein, and no sweetener or emulsifier. The ten options below also include chocolate whey, casein, egg, and pea protein, because avoiding gums should not force everyone into the same dairy shake.

How We Chose

Ingredient fit comes first: these exact flavors list no xanthan, guar, acacia, cellulose, gellan, or locust bean gum, and no carrageenan. Sunflower lecithin is an emulsifier, not a gum, so it does not disqualify a formula. We then compared protein per labeled serving, protein source, added sweeteners, package commitment, and allergens. Those criteria favor Naked Whey’s single-ingredient formula for general use, while leaving room for a flavored isolate or a dairy-free alternative. Scores are editorial assessments of those tradeoffs, not a promise that removing gums improves digestion or muscle growth. A different flavor can have a different ingredient list; use the exact version named here.

Our Top Picks

Best Overall: Naked Whey Unflavored

Naked Whey Unflavored 5 lb

Best Overall

★★★★★ 4.6/5

Check current price

A single-ingredient whey concentrate for buyers who want protein without gums, sweeteners, or an added emulsifier and already know they tolerate dairy.

Pros

• One ingredient: whey concentrate
• 25 g protein per serving
• 76 servings in the selected tub

Cons

• Contains milk and lactose
• Large 5 lb commitment

Check Price on Amazon

Naked Whey is the starting point if your goal is subtraction. The unflavored 5 lb tub contains whey protein concentrate, with 25 g protein and 120 calories per serving. There is no flavor blend to work around and no lecithin to distinguish from a thickener.

Skip this if lactose is the problem you are trying to solve. This is a concentrate, not an isolate. Compared with Levels Unflavored, it removes sunflower lecithin as well; compared with NOW Whey Isolate, it asks you to commit to a much larger tub. That trade makes sense for an established daily staple, not an uncertain first purchase.

Best Chocolate Isolate: Transparent Labs Milk Chocolate

Transparent Labs Whey Isolate Milk Chocolate 2 lb

Best Chocolate Isolate

★★★★★ 4.5/5

Check current price

A chocolate whey isolate with 28 g protein per serving for buyers who want a flavored formula without gum-based thickeners.

Pros

• 28 g protein per serving
• 30 labeled servings
• No gum-based thickener

Cons

• Stevia-sweetened
• Contains milk

Check Price on Amazon

Transparent Labs keeps a flavored option on the list without turning it into a concentrate-and-thickener blend. Milk Chocolate lists whey isolate, cocoa, natural flavor, salt, stevia, and sunflower lecithin. A serving contains 28 g protein and 130 calories.

Skip this if you dislike stevia or need a completely unsweetened powder. Naked Chocolate Whey uses coconut sugar instead, but adds 8 g carbohydrate per serving versus this formula’s 1 g. For a lower-carbohydrate chocolate option, Transparent Labs is the clearer fit; for avoiding stevia specifically, Naked is the better match.

Best Zero-Carb Option: Isopure Unflavored

Isopure Zero Carb Unflavored 3 lb

Best Zero-Carb Option

★★★★☆ 4.4/5

Check current price

An unflavored isolate with zero labeled carbohydrate, but the lecithin declaration makes it unsuitable for buyers excluding all soy ingredients.

Pros

• 25 g protein and 100 calories
• 0 g labeled carbohydrate
• 47 servings in this size

Cons

• Label permits sunflower or soy lecithin
• Contains milk

Check Price on Amazon

Isopure’s selected 3 lb unflavored tub lists 25 g protein, 100 calories, and zero carbohydrate per serving. Its short formula contains whey isolate and lecithin, rather than a gum system. The 47-serving size sits between the small NOW tub and Naked’s 76-serving concentrate.

Skip this if soy ingredients are also on your exclusion list: the label allows sunflower or soy lecithin. NOW Whey Isolate names sunflower lecithin instead. Isopure earns its place for the zero-carb formulation, not because it is automatically the shortest list or the right answer for every allergy.

Best Smaller Whey Tub: NOW Sports Whey Isolate

NOW Sports Whey Protein Isolate Unflavored 1.2 lb

Best Smaller Whey Tub

★★★★★ 4.5/5

Check current price

A smaller unflavored whey isolate with sunflower lecithin, suited to buyers who want fewer ingredients without committing to five pounds.

Pros

• 24 g protein per serving
• Whey isolate and sunflower lecithin
• Smaller 1.2 lb package

Cons

• Contains milk
• Fewer servings than bulk tubs

Check Price on Amazon

NOW’s 1.2 lb tub is a sensible size when you have not settled on a daily powder. The formula pairs whey isolate with less than 1% sunflower lecithin, and a serving supplies 24 g protein, 110 calories, and 1 g carbohydrate.

Skip this if you want no emulsifier at all; Naked Whey is the simpler formula. NOW is a better comparison with Isopure for someone who wants an isolate but prefers a smaller package and explicitly named sunflower lecithin. It remains milk protein, regardless of the absence of gums.

Best Compact Daily Isolate: NutraBio Raw Unflavored

NutraBio Whey Protein Isolate Raw Unflavored 20 servings

Best Compact Daily Isolate

★★★★☆ 4.4/5

Check current price

An unsweetened 20-serving isolate with 25 g protein per portion for buyers who prefer a compact tub over a bulk bag.

Pros

• 25 g protein per serving
• Less than 1 g carbohydrate
• No added sweetener

Cons

• Only 20 servings in this tub
• Contains milk

Check Price on Amazon

NutraBio’s Raw Unflavored version uses whey isolate and sunflower lecithin. Its 28.74 g portion contains 25 g protein and 110 calories, so roughly 87% of the portion weight is protein. The remaining weight is not evidence of filler; protein powders also contain moisture, minerals, and other constituents.

Skip this if you want a month’s supply from one tub at one serving a day: this size has 20 servings. NOW is a close smaller-package alternative; Isopure is the larger one. Compare their checkout prices per equal amount of protein rather than their tub prices alone.

Best Two-Ingredient Concentrate: Levels Unflavored

Levels Grass Fed Whey Unflavored 2 lb

Best Two-Ingredient Concentrate

★★★★☆ 4.3/5

Check current price

A two-ingredient whey concentrate that splits the difference between Naked's large single-ingredient tub and smaller whey isolate packages.

Pros

• 25 g protein per serving
• Whey concentrate and sunflower lecithin
• 2 lb size

Cons

• Contains milk and lactose
• Not a single-ingredient powder

Check Price on Amazon

Levels Unflavored combines whey concentrate with sunflower lecithin. Its 32 g portion contains 25 g protein, 130 calories, and 2 g carbohydrate. That is a useful middle ground if you want neither a sweetened shake nor a five-pound purchase.

Skip this if avoiding lactose or every added ingredient is the priority. Naked Whey removes the lecithin; NOW Isolate changes the protein type. Levels is worth choosing for this particular two-ingredient formula and package size, not for an assumption that grass-fed whey produces greater muscle gains.

Best Without Stevia: Naked Chocolate Whey

Naked Whey Chocolate 5 lb

Best Without Stevia

★★★★☆ 4.3/5

Check current price

A three-ingredient chocolate concentrate sweetened with coconut sugar, for buyers who want neither gum thickeners nor stevia in their shake.

Pros

• Three ingredients
• 25 g protein per serving
• Coconut sugar instead of stevia

Cons

• 3 g added sugar per serving
• Milk and coconut ingredients

Check Price on Amazon

Naked Chocolate Whey contains whey concentrate, organic coconut sugar, and organic cacao. The 38 g serving supplies 25 g protein, 160 calories, and 8 g carbohydrate, including 3 g added sugar. This is not the unflavored formula with identical macros.

Skip this if added sugar, lactose, or a 60-serving commitment is unwelcome. Transparent Labs gives you more protein per serving with fewer carbohydrates, but uses stevia. Naked is the more direct choice when the sweetener itself is the reason other gum-free chocolate powders do not fit.

Best Casein: Naked Casein Unflavored

Naked Casein Unflavored 5 lb

Best Casein

★★★★☆ 4.4/5

Check current price

Single-ingredient micellar casein for buyers who want a different dairy protein source without gums, flavors, sweeteners, or an emulsifier.

Pros

• Single-ingredient micellar casein
• 26 g protein per serving
• 76 servings

Cons

• Contains milk
• Large 5 lb tub

Check Price on Amazon

Naked Casein contains micellar casein, rather than whey. A 30 g serving lists 26 g protein and 110 calories. Its ingredient list is as short as Naked Whey’s, while the 76-serving tub has the same substantial storage commitment.

Skip this if you need to avoid milk protein. Casein is not a dairy-free workaround, and a thicker preparation does not prove added gums. Choose it because you want casein in your routine; choose whey if that already suits your meals. There is no need to buy both merely because one is marketed for nighttime.

Best Egg Option: NOW Sports Egg White Protein

NOW Sports Egg White Protein Unflavored 1.2 lb

Best Egg Option

★★★★☆ 4.2/5

Check current price

An egg-white formula with added BCAAs and sunflower lecithin, giving a smaller protein portion than the whey and pea options here.

Pros

• 15 g protein per serving
• Egg-based rather than dairy protein
• No gum thickener

Cons

• Contains egg
• Smaller protein portion than most picks

Check Price on Amazon

NOW Egg White supplies 15 g protein per 20 g portion, with 70 calories. The current formula includes egg white powder, a small added BCAA blend, and sunflower lecithin. It is gum-free, but it is not a single-ingredient egg powder.

Skip this if you have an egg allergy or want 25 g protein from one labeled serving. Reaching 25 g requires about 1.67 servings, so a 27-serving tub is not equivalent to 27 whey-size protein portions. NOW Pea supplies 24 g per serving and is the plant alternative.

Best Plant Protein: NOW Sports Pea Protein

NOW Sports Pea Protein Unflavored 2 lb

Best Plant Protein

★★★★☆ 4.4/5

Check current price

A single-ingredient pea isolate with 24 g protein for buyers excluding dairy and egg ingredients as well as gum-based thickeners.

Pros

• 24 g protein per serving
• Single-ingredient yellow pea isolate
• No added sweetener

Cons

• Pea allergies still matter
• Shared-facility allergen caution

Check Price on Amazon

NOW Pea contains yellow pea protein isolate, with 24 g protein and 120 calories per 33 g portion. It is the only entirely plant-derived protein source in this particular shortlist, without a creamer or flavor blend to lengthen the ingredient list.

Skip this if you are allergic to peas or need a guaranteed allergen-free facility. Its shared-facility statement still matters. Compared with NOW Egg White, it supplies 9 g more protein per labeled serving; compared with Naked Whey, it changes the protein source rather than promising a superior muscle-building effect.

Comparison Table

How to Buy a Protein Powder Without Gums

Separate thickeners from emulsifiers

Start with the full ingredient panel, not the word clean. Xanthan, guar, acacia, cellulose, gellan, locust bean gum, and carrageenan are the exclusions used here. Lecithin serves a different purpose, helping ingredients disperse. If you also want no lecithin, narrow this list to Naked Whey Unflavored, Naked Chocolate Whey, Naked Casein, or NOW Pea. Do not reject a useful formula because two unfamiliar ingredient names sound alike.

Identify the restriction you actually need

Gum-free is not shorthand for lactose-free, soy-free, or dairy-free. Naked Whey and Levels use concentrate; several other picks are isolates; both categories remain milk protein. Isopure’s unflavored ingredient statement can include soy lecithin. For dairy-free ingredients, look at NOW Egg White or NOW Pea, then check the separate allergen and facility statements. The FDA’s guidance on reading a nutrition label is useful because serving information and ingredient information answer different questions.

Compare equal protein portions

Use checkout price divided by total grams of protein, then multiply by 25 for the cost of a 25 g portion. A tub with 20 servings of 25 g protein contains 500 g protein in total. A tub with 27 servings of 15 g contains 405 g. The second tub has more labeled servings but less protein. This is why NOW Egg White needs a different value calculation from NutraBio. Shipping, subscriptions, and discounts can change the result; a large tub is not automatically cheaper.

Do not pay for an exclusion you do not need

These powders solve an ingredient preference, not a proven shortcut to growth. The ISSN protein position stand puts total intake and adequate meal portions ahead of ingredient marketing. For healthy people who exercise, it describes a broad daily range of 1.4-2.0 g/kg, with individual needs varying. A gum-free scoop cannot rescue a diet that consistently falls short. Count food first and use powder for the remaining gap.

Use symptoms as a reason to investigate, not to guess

Removing gums may match your preferences, but it cannot establish what caused discomfort. Lactose, portion size, sweeteners, added fiber, and the rest of the meal are separate variables. Persistent or severe symptoms deserve medical advice rather than an ever-longer banned-ingredient list. For other ingredient preferences, compare our stevia-free protein picks and low-carb protein guide. Neither label replaces an allergy assessment.

Frequently Asked Questions

Is gum-free protein powder better for muscle growth?

Not simply because it leaves out gums. Adequate protein, resistance training, total food intake, and consistency matter more than that exclusion. Choose a gum-free powder when it fits your ingredient preferences, then judge it by the protein amount and how it fits your meals. Do not assume a longer ingredient list means less effective protein.

Does sunflower lecithin count as a gum?

No. It is an emulsifier, not one of the gum thickeners excluded here. NOW Whey Isolate, Levels, and NutraBio can therefore qualify with sunflower lecithin present. If you want protein without any emulsifier, choose a formula such as Naked Whey Unflavored or NOW Pea instead. That is a separate, narrower preference.

Can a gum-free powder still make a thick shake?

Yes. Protein type, concentration, liquid amount, and other ingredients affect consistency. Casein does not need a gum on its ingredient list to behave differently from whey isolate. Do not use thickness alone to infer a hidden additive. Read the actual ingredient panel and follow the preparation directions for the selected powder.

Which options contain no added sweetener?

Naked Whey Unflavored, Isopure Unflavored, NOW Whey Isolate, NutraBio Raw Unflavored, Levels Unflavored, Naked Casein, NOW Egg White, and NOW Pea have no added sweetener in the formulas selected here. Transparent Labs Milk Chocolate uses stevia. Naked Chocolate Whey uses coconut sugar. Flavored products from the same brands may differ.

Are these powders suitable for food allergies?

Not as a blanket group. Most contain milk; NOW Egg White contains egg; peas can also cause allergic reactions. Ingredient absence does not establish cross-contact safety. Read the package you receive and discuss a diagnosed allergy with your clinician and the manufacturer. A gum exclusion is not an allergen certification.

Bottom Line

Naked Whey Unflavored wins for the simplest dairy formula: one ingredient and 25 g protein per serving. That recommendation changes if lactose, milk allergy, or a large tub is the wrong fit. NOW Whey Isolate is the smaller dairy purchase, Transparent Labs is the flavored isolate, and NOW Pea is the single-ingredient plant option. Choose the restriction you need, not the longest collection of free-from claims. Our sensitive-stomach protein guide covers a different set of buying considerations.
