10 Best Protein Shakes Without Sucralose of 2026

A shake can have no sucralose and still contain stevia, monk fruit, added sugar or all three. That makes the ingredient list just as important as the protein number. These ten ready-to-drink picks cover dairy and plant-based recipes, with 18-30g protein per container and the other sweeteners spelled out.

Written by Tom Miller, CSCS. Updated: November 2026.

Read the exact flavor: Sucralose-free is an ingredient preference, not a promise that a drink is sugar-free, unsweetened or suitable for every allergy. The picks below refer to the named chocolate products, not every shake from each brand.

How We Chose

We compared ready-to-drink shakes from ten different makers, with sucralose excluded and at least 15g protein required per complete container. All ten picks exceed that minimum. We kept powders and low-protein plant milks out of the list, and counted each brand once rather than treating extra flavors as extra choices.

Our editorial ratings weigh the useful protein portion against calories, sugar, fiber, other sweeteners and practical packaging. A 30g milk shake and an 18g coconut-milk drink serve different needs. Dairy-free options earn their place for that difference, not because plant protein automatically outranks milk. The main drawbacks are visible: milk or nut ingredients, stevia, added sugar, and cans that cannot be resealed. For a wider selection without this ingredient filter, see our ready-to-drink protein shake guide.

Our Top Picks

Best Overall: Oikos Chocolate Protein Shake

Oikos Chocolate Protein Shake 30g, 12 Bottles

Best Overall

★★★★☆ 4.4/5

Check current price

A resealable 12-ounce milk-based shake combines 30g protein with one gram of sugar and six grams of total fiber, sweetened with stevia.

Pros

• 30g protein per bottle
• 1g sugar with no added sugar
• 6g total fiber

Cons

• Contains milk and stevia
• 2.5g saturated fat per bottle

Check Price on Amazon

Oikos combines milk protein concentrate and micellar casein isolate in a 180-calorie bottle. Its 6g total dietary fiber includes the 5g prebiotic fiber called out on the front.

Compared with Orgain’s 30g Chocolate Fudge, Oikos adds 4g more fiber and 20 more calories. The 12-ounce bottle also gives you an extra ounce of liquid and a screw cap. Unopened bottles do not need refrigeration.

Skip this if you avoid milk, stevia or a larger added-fiber serving. Orgain has the same protein with less fiber; OWYN is dairy-free. Oikos labels this as a food supplement, not a product for weight reduction.

Best Dairy-Free Without Stevia: OWYN Dark Chocolate

OWYN Dark Chocolate 20g Protein Shake, 12 Bottles

Best Dairy-Free Without Stevia

★★★★☆ 4.4/5

Check current price

OWYN's 12-ounce Dark Chocolate bottle uses cane sugar and monk fruit rather than stevia, with 20g plant protein and three grams of fiber.

Pros

• 20g plant protein
• No stevia in this recipe
• 3g fiber per bottle

Cons

• 4g added sugar
• Less protein than the 30g dairy picks

Check Price on Amazon

This is OWYN’s original 20g shake, not its Pro Elite line. The 180-calorie bottle contains 4g sugar, all added, and 3g fiber. Its protein blend includes pea and pumpkin seed protein.

OWYN is the easier starting point than Ripple if you want a dairy-free bottle with less added sugar: 4g versus 9g for Ripple’s selected chocolate bottle. Both contain 20g protein and use cane sugar plus monk fruit.

Skip this if you need zero added sugar or a 30g protein portion in one drink. The maker tests and validates for the top nine allergens, but individual pea or seed allergies still require an ingredient check. This recipe contains no stevia; that does not make it unsweetened.

Best Lower-Calorie Dairy Pick: Slate Classic Chocolate

Slate Classic Chocolate 20g Protein Milk Shake, 12 Cans

Best Lower-Calorie Dairy Pick

★★★★☆ 4.3/5

Check current price

An 11-ounce lactose-free milk shake puts 20g protein into 100 calories, with monk fruit and stevia in the current Classic Chocolate recipe.

Pros

• 20g protein at 100 calories
• 1g sugar and no added sugar
• Lactose-free milk formula

Cons

• Contains milk and stevia
• Can cannot be resealed

Check Price on Amazon

Slate has the lowest calorie count here: 100 calories for 20g protein. That is 40 fewer calories than ICONIC for the same protein portion. The can contains 1g sugar and 2g fiber.

The current Classic Chocolate recipe uses monk fruit and stevia. Some package ingredient lists also include allulose, so inspect the can if that is another ingredient you avoid. Unopened cans are shelf-stable.

Skip this if you have a milk allergy or want a resealable container. Lactose-free milk still contains milk proteins. The 100-calorie serving also makes more sense as a protein addition than as a full meal on its own.

Best Zero-Sugar Dairy Pick: ICONIC Chocolate Truffle

ICONIC Chocolate Truffle Protein Drink, 12 Bottles

Best Zero-Sugar Dairy Pick

★★★★☆ 4.2/5

Check current price

Chocolate Truffle combines 20g milk protein with zero grams of sugar and four grams of fiber, using monk fruit and stevia for sweetness.

Pros

• 20g protein
• 0g sugar and 4g fiber
• Lactose-free milk protein isolate

Cons

• Contains milk, stevia and monk fruit
• Less protein than Oikos or Orgain

Check Price on Amazon

ICONIC uses grass-fed milk protein isolate, chicory root fiber, monk fruit and stevia. The result on the nutrition panel is 20g protein, 140 calories, 0g sugar and 4g fiber.

Choose it over Slate when zero total sugar and an extra 2g fiber matter more than saving 40 calories. Choose Oikos when your priority is 30g protein rather than 20g. Neither comparison establishes a benefit from the grass-fed label alone.

Skip this if you avoid milk, chicory fiber or stevia. The lactose-free claim does not make it dairy-free. The ingredients include locust bean gum and gellan gum, so this is not a gum-free recipe either.

Best High-Fiber Almond-Based Pick: Koia Cacao Bean

Koia Cacao Bean Nutrition Shake 20g, 12 Cartons

Best High-Fiber Almond-Based Pick

★★★★☆ 4.2/5

Check current price

The shelf-stable Cacao Bean Nutrition carton pairs 20g plant protein with six grams of fiber in an almond-milk recipe containing cane sugar and monk fruit.

Pros

• 20g plant protein
• 6g fiber
• Shelf-stable 11-ounce carton

Cons

• Contains almonds and coconut
• 3g added sugar

Check Price on Amazon

Buy the 20g Nutrition carton for this comparison, not Koia’s refrigerated 18g bottle. This 11-ounce version contains 180 calories, 3g sugar and 6g fiber from a recipe that includes agave and chicory fibers.

Brown rice, pea and chickpea proteins sit in an almond-milk base. Koia matches Kate Farms’ 6g fiber, but has 5g less protein and 3g more sugar. It does not need refrigeration before opening.

Skip this if you avoid almonds or coconut, or prefer less added fiber. OWYN has half the fiber and no almond-milk base. Koia makes sense when you specifically want the 20g protein and 6g fiber combination, not merely any dairy-free shake.

Best Coconut-Milk Pick: ALOHA Chocolate Sea Salt

ALOHA Chocolate Sea Salt Protein Drink, 12 Cartons

Best Coconut-Milk Pick

★★★★☆ 4.1/5

Check current price

A coconut-milk base, coconut sugar and monk fruit distinguish this 18g protein carton from stevia-sweetened dairy shakes and almond-based plant alternatives.

Pros

• 18g pea and brown rice protein
• No stevia in this recipe
• 3g fiber

Cons

• 5g sugar, including 4g added
• Contains coconut; shared-facility warning

Check Price on Amazon

ALOHA’s current Chocolate Sea Salt carton uses coconut sugar and monk fruit, with pea and brown rice protein. One 11-ounce drink contains 180 calories, 18g protein, 5g sugar and 3g fiber.

Against OWYN, you give up 2g protein and add 1g total sugar at the same calorie count. The reason to choose ALOHA is its coconut-milk formulation and absence of stevia, not a bigger protein serving. The recipe also includes coconut-derived MCT oil.

Skip this if you avoid coconut or require strict separation from other allergens. The maker identifies a facility that also handles eggs, milk, peanuts and soy. Coconut sugar still counts toward added sugar; it is not a free pass around the nutrition label.

Best Compact 30g Carton: Orgain Chocolate Fudge

Orgain 30g Protein Shake Chocolate Fudge, 12 Cartons

Best Compact 30g Carton

★★★★☆ 4.3/5

Check current price

Orgain's 11-ounce Chocolate Fudge carton contains 30g milk protein, one gram of sugar and two grams of fiber, sweetened with monk fruit and stevia.

Pros

• 30g milk protein
• 160 calories and 1g sugar
• 2g fiber

Cons

• Contains milk and stevia
• Less fiber than Oikos

Check Price on Amazon

This Orgain is a dairy shake. Milk protein isolate and concentrate supply 30g protein in a 160-calorie carton, with 1g sugar and no added sugar. The sweeteners are monk fruit and stevia extract Reb M.

It matches Oikos’ protein in one less ounce, with 20 fewer calories and 4g less fiber. That is a useful trade when the 6g fiber in Oikos is more than you want in one sitting. Both selected cases contain 12 drinks.

Skip this if you need a plant-based drink or avoid stevia. The Orgain name covers several different recipes and protein amounts. This 30g Chocolate Fudge carton should not be confused with its 16g nutrition shakes or vegan lines.

Best Higher-Calorie Plant Bottle: Ripple Chocolate

Ripple Chocolate Protein Shake 12 fl oz, 12 Bottles

Best Higher-Calorie Plant Bottle

★★★★☆ 4.0/5

Check current price

Ripple's 12-ounce chocolate bottle supplies 20g pea protein and uses cane sugar with monk fruit, with more added sugar than OWYN.

Pros

• 20g pea protein
• No stevia in the selected bottle's recipe
• Resealable 12-ounce bottle

Cons

• 9g added sugar
• 210 calories for 20g protein

Check Price on Amazon

The selected 12-ounce Ripple bottle contains 20g protein, 2g fiber and 9g sugar, all added. Its nutrition panel lists 210 calories. Cane sugar and monk fruit sweeten the pea-protein recipe.

Compared with OWYN, you get the same protein with 30 more calories and 5g more added sugar. That can fit when you want a higher-calorie snack, but it is a disadvantage if you are minimizing added sugar. This selection is the bottle, not Ripple’s newer 11-ounce carton.

Skip this if you want low added sugar or the most protein per calorie. OWYN is the closer plant-based alternative with less sugar; Slate is lower in calories but contains milk. Neither is a straight swap for every dietary restriction.

Best Higher-Protein Plant Pick: Kate Farms Chocolate

Kate Farms High Protein Nutrition Shake Chocolate, 12 Cartons

Best Higher-Protein Plant Pick

★★★★☆ 4.2/5

Check current price

A chocolate pea-protein carton raises the plant-based portion to 25g while keeping sugar at zero grams, with six grams of fiber and stevia.

Pros

• 25g pea protein
• 0g sugar and 6g fiber
• 160 calories per carton

Cons

• Contains stevia and monk fruit
• 6g fiber may not suit every routine

Check Price on Amazon

Kate Farms has the most protein among the plant-based picks here: 25g in an 11-ounce, 160-calorie carton. It also contains 6g fiber and 0g sugar, with monk fruit and stevia extract Reb M.

Compared with Koia, you get 5g more protein, the same fiber and 20 fewer calories without an almond-milk base. The ingredient list is longer than a simple protein-and-water drink and includes a botanical extract blend. Refrigerate after opening and use within four days.

Skip this if you want a lower-fiber drink or avoid stevia. This is the everyday High Protein Nutrition Shake, not a tube-feeding formula. Its brand name is not a reason to use it for a medical condition without advice tailored to you.

Best Fava-and-Pea Blend: Ensure Plant-Based Chocolate

Ensure Plant-Based Protein Chocolate, 12 Cartons

Best Fava-and-Pea Blend

★★★★☆ 4.1/5

Check current price

Ensure Plant-Based Chocolate combines fava bean and pea proteins with five grams of fiber, but its seven grams of sugar matter for daily use.

Pros

• 20g fava and pea protein
• 5g fiber
• Dairy- and soy-free recipe

Cons

• 7g added sugar
• Contains stevia and monk fruit

Check Price on Amazon

Ensure’s Plant-Based Chocolate contains 20g protein, 180 calories, 5g fiber and 7g sugar in an 11-ounce carton. Its sweeteners include organic cane sugar, stevia and monk fruit.

The fava-and-pea blend distinguishes it from OWYN’s pea-and-pumpkin combination. It has 2g more fiber and 3g more sugar than OWYN at the same protein and calorie amounts. The manufacturer identifies this specific line as dairy- and soy-free.

Skip this if your priorities are zero added sugar or avoiding stevia. Kate Farms has more protein and no sugar, while OWYN leaves out stevia. Do not apply this product’s ingredient list to Ensure Original, Plus or other Ensure shakes.

Comparison Table

Numbers below are for one complete container of the named chocolate flavor. The linked options contain 12 drinks each. Formulas and packaging can change, so read the container you receive.

How to Choose a Protein Shake Without Sucralose

Decide which other sweeteners you actually want

Removing sucralose does not remove sweetness. Oikos uses stevia; Orgain and ICONIC combine stevia with monk fruit. OWYN and Ripple use cane sugar with monk fruit, while ALOHA uses coconut sugar with monk fruit. Those are meaningful differences if another sweetener is the reason you are changing drinks.

Read the ingredient list separately from the sugar number. Stevia and monk fruit will not necessarily appear as grams of sugar. Conversely, coconut sugar is still added sugar. Avoid treating a front-label phrase as a complete description of the recipe.

Match the protein to the gap in your meals

Oikos and Orgain have 30g protein, Kate Farms has 25g, and most others have 20g. ALOHA has 18g. The ISSN protein position stand discusses 20-40g high-quality protein servings for exercising adults, with the useful amount depending on body size, age and training. That is context, not a rule that every drink must contain 40g.

A shake can close a protein gap without replacing a meal. Slate’s 100 calories and 20g protein illustrate the distinction. If larger single-container portions are your priority, compare our 30g-plus ready-to-drink shakes, but apply your sucralose filter to each exact flavor.

Separate total sugar, added sugar and calories

The FDA explains that total sugar includes naturally occurring and added sugars. Added sugar is already included in that total, so do not add the two figures together. Oikos has 1g total sugar with 0g added; OWYN has 4g total, all added.

Zero sugar does not mean zero calories. ICONIC has 140 calories and Kate Farms has 160. Compare cost per complete drink, then protein and calories at that portion. A cheaper case is not a better buy if you need two containers to reach the protein amount you wanted.

Keep allergy restrictions separate from lactose

Slate and ICONIC are lactose-free but contain milk. Koia uses almonds, and ALOHA uses coconut. A dairy-free choice can still be unsuitable for a particular plant, nut or seed allergy. For more dairy-free choices, see our plant-based shake guide; inspect the exact ingredient and cross-contact statements before buying.

Choose fiber and packaging you will use

Oikos, Koia and Kate Farms each contain 6g fiber; Orgain and Slate have 2g. More is not automatically better when you already eat plenty of fiber or want a smaller serving before training. Pick the amount that fits the rest of your food.

Keep shelf-stable drinks within the manufacturer’s storage conditions. Shelf-stable describes an unopened product, not a drink left warm after opening. Follow each bottle or carton’s refrigeration and use-by directions. A screw cap is useful for closing the package, but it does not replace refrigeration. Slate’s can cannot be resealed.

Alternatives and Drawbacks

Do not buy a sucralose-free shake solely because you expect the missing ingredient to improve muscle growth or weight loss. The practical gains come from a recipe you can use, an appropriate protein portion and a diet that fits your goals. This list is not a ranking of sweetener safety.

Powders are worth considering when cost per serving matters more than opening a finished drink. Regular milk, yogurt or a meal can also supply protein. A ready-to-drink shake earns its place through convenience; there is no requirement to use one every day.

Frequently Asked Questions

Which ready-to-drink protein shakes have no sucralose?

The named chocolate picks from Oikos, OWYN, Slate, ICONIC, Koia, ALOHA, Orgain, Ripple, Kate Farms and Ensure Plant-Based have no sucralose in their ingredient lists. Use the exact product names above. A different line or flavor from the same brand can have a different recipe, protein amount or sweetener blend.

Does sucralose-free mean sugar-free?

No. Ripple’s selected bottle has 9g sugar, Ensure Plant-Based has 7g and ALOHA has 5g. ICONIC and Kate Farms list 0g sugar, but still use sweeteners. Look at both the nutrition panel and ingredients. If added sugar matters to you, check that line separately rather than relying on total sugar alone.

Which picks avoid both sucralose and stevia?

OWYN Dark Chocolate, ALOHA Chocolate Sea Salt and the selected Ripple chocolate bottle use monk fruit with sugar rather than stevia. They are not unsweetened: their sugar amounts differ. Oikos, Orgain, ICONIC, Kate Farms and Ensure Plant-Based contain stevia. Check your delivered package when you are excluding more than one ingredient.

Are lactose-free protein shakes also dairy-free?

No. Slate and ICONIC remove lactose but still use milk protein. Milk allergy and lactose intolerance are different restrictions. If milk protein is the issue, start with an appropriate plant-based recipe rather than a lactose-free dairy drink. Our lactose-free shake guide covers the broader distinction, including milk-based options.

Are chocolate protein shakes caffeine-free?

Do not assume so. Cocoa can contain naturally occurring caffeine even without coffee or added caffeine on the label. Kate Farms’ ingredient blend also includes coffeeberry and green tea extracts. These are the chocolate variants, not coffee shakes, but the ingredient lists do not establish a universal zero-caffeine amount. Ask the maker when strict avoidance matters.

Can I use one of these as breakfast?

A shake can be part of breakfast, but its protein number does not make it a complete meal. The drinks here range from 100 to 210 calories. Consider the rest of your meal and appetite rather than replacing breakfast solely to reach a protein target. Follow individualized advice if you use nutrition drinks for a medical need.

Bottom Line

Oikos is our dairy-based default for 30g protein with 1g sugar and 6g fiber in a resealable bottle. Orgain keeps the same protein in a smaller, lower-fiber carton. For dairy-free choices, OWYN avoids stevia, while Kate Farms raises the plant-protein portion to 25g with no sugar.

Start with the ingredients you need to exclude, then choose the protein, fiber and calorie amounts you want. No sucralose does not mean no sugar, no stevia or no allergens. The exact chocolate recipe matters more than the brand name alone.
