Koia Protein Pop is the closest ready-to-drink match for a vegan, dairy-free protein soda. If a powder is acceptable, Rocka Clear Protein and Applied Nutrition Clear Vegan Protein provide plant-based clear drinks with very little or no added sugar. Dairy-free people who are not vegan have additional choices, including beef-based clear isolates and mixed-source formulas. A clear or carbonated label alone does not establish that a drink is vegan: some clear products use milk-derived whey.
The right choice depends on four checks: the protein source, sugar definition, serving format and whether you want a can or a drink mixed at home. The comparison below separates those details so “dairy-free,” “vegan,” “sugar-free” and “clear protein” are not treated as interchangeable terms.

Quick answer: which protein soda alternative fits your diet?
Use this shortlist to narrow the field before comparing flavors or serving sizes:
- Vegan canned soda: Koia Protein Pop is the most direct match because it is a carbonated, ready-to-drink can identified as vegan and dairy-free.
- Vegan powder: Rocka Clear Protein uses hydrolyzed pea protein, while Applied Nutrition Clear Vegan Protein uses hydrolyzed pea isolate. Both are fruit-style clear drinks rather than creamy shakes.
- Dairy-free but not vegan: Applied Nutrition Clear Protein Isolate is made from hydrolyzed beef; PVL ISO CLEAAR combines beef and plant sources.
- Carbonated but not vegan: Barebells Protein Soda uses clear whey isolate derived from milk.
- Still, non-carbonated alternative: Alpro Soya No Sugars is a vegan, dairy-free soy beverage with a sugar-free claim, but it is not a soda or a clear-protein product.
- Additional canned formula: PURIS lists protein, prebiotic fiber and sugar per 12-fluid-ounce can, but the available formula information does not establish a vegan or dairy-free status.
For most vegan shoppers, start with Koia if convenience and carbonation matter. Choose one of the pea-protein powders when the lowest sugar level or a larger serving of protein matters more than having a can.

What “protein soda,” “clear protein” and “dairy-free” actually mean
Protein soda is a format, not a dietary guarantee
Protein soda generally means a sparkling, flavored beverage that supplies protein without the thick, milky texture of a traditional shake. Ready-to-drink cans are convenient and require no shaker or mixing. Powdered clear proteins are usually stirred or shaken with water, then consumed as a fruit-style drink. Carbonation and a transparent appearance describe the beverage experience; they do not identify the ingredient source.
Vegan and dairy-free are different tests
Vegan products contain no animal-derived ingredients. In this group, pea protein is the relevant plant source: Rocka and Applied Nutrition’s vegan formula use pea-based protein. Dairy-free means no milk ingredients, but a product can still come from an animal. Hydrolyzed beef protein is dairy-free yet not vegan, which is why Applied Nutrition Clear Protein Isolate and the beef component of PVL ISO CLEAAR belong in a separate category.
Milk-derived clear whey creates the opposite trap. Barebells Protein Soda is clear and carbonated, but its whey isolate comes from milk, so it is neither vegan nor suitable for a dairy-free diet. Always read the protein-source line and allergen statement instead of relying on the word “clear.”
“Sugar-free,” “no added sugar” and a low-sugar number are not identical
A zero-sugar claim is different from a no-added-sugar claim. Rocka states that its product has no added sugar, while Applied Nutrition Clear Vegan Protein reports less than 0.3 grams of sugar per 15-gram serving. Applied Nutrition Clear Protein Isolate and PVL ISO CLEAAR report zero sugar. Koia Protein Pop lists 2 grams per can. Those figures are not directly interchangeable unless the serving sizes are considered: a can, a scoop and a 15-gram serving represent different amounts of product.

“Not stated” means the available product information does not establish that specification; it is not a claim that the product lacks it. Formulas, flavors and regional labels can change, so check the package in your market before buying.
Best vegan protein soda and clear-protein choices
Koia Protein Pop: the closest one-step match
Koia Protein Pop is the strongest answer when the request is specifically for a vegan protein soda rather than a protein drink that happens to be clear. It comes in a ready-to-drink carbonated can and uses clear pea protein. Healthline’s 2026 description identifies it as vegan and dairy-free and reports 10 grams of protein, 2 grams of sugar and 70 calories in a 12-fluid-ounce can.
Rank #2
- Ideal for Gifting
- Ideal for a bookworm
- Compact for travelling
That combination makes it the easiest choice for commuting, travel or any situation in which mixing a powder is inconvenient. Its sugar amount is low but not zero, so someone following a strict zero-sugar target should compare the label with the powder options below. The 10-gram protein amount is also a smaller serving than the highest-protein powders, which may matter if the drink is intended to replace a larger shake.

Rocka Clear Protein: a vegan powder with a no-added-sugar position
Rocka describes Clear Protein as a vegan protein soda made from hydrolyzed pea protein. The product page states that it provides 13 grams of protein per 18-gram serving without added sugar. It is a powder mixed with water, not a pre-carbonated can, and is presented as a fruit-style clear drink.
This format can work well when you want control over how much water you use or prefer to keep a tub of powder at home. “No added sugar” does not necessarily mean the nutrition panel will show exactly zero total sugars, so read the current label for the flavor and market you are purchasing. The pea source makes the vegan classification straightforward, provided the package’s allergen and manufacturing statements fit your needs.
Applied Nutrition Clear Vegan Protein: the lowest stated sugar level among the vegan powders
Applied Nutrition’s Clear Vegan Protein is another hydrolyzed pea-isolate powder. The manufacturer positions it as a clear drink rather than an ordinary creamy shake. Its stated serving is 15 grams and provides more than 11 grams of protein, 1.4 grams of carbohydrate, less than 0.3 grams of sugar and 49 calories.
The sub-0.3-gram sugar figure is the most precise low-sugar statement among the vegan choices listed here. It is still a powder, so it does not provide the instant carbonation of a can. If your priority is minimizing sugar while keeping a plant-based ingredient source, this is the clearest fit on the available figures. Confirm the serving scoop, flavor label and mixing directions on the package because a different serving size changes the comparison.

Dairy-free choices that are not vegan
Applied Nutrition Clear Protein Isolate: high protein from hydrolyzed beef
Applied Nutrition says its Clear Protein Isolate is a dairy-free protein source made from 100% hydrolyzed beef. The product page reports more than 27 grams of protein, 111 calories and zero sugar per serving. It can suit someone avoiding milk while still consuming animal products.
It cannot meet a vegan requirement because beef is animal-derived. That distinction should be made before considering flavor, calories or protein density. People who avoid beef for ethical, religious or personal reasons need a plant-based product instead, even though this formula is dairy-free.
PVL ISO CLEAAR: a mixed beef-and-plant formula
PVL ISO CLEAAR lists beef and plant sources and reports 20 grams of protein, zero sugar and 80 calories per serving. It is therefore a dairy-free, mixed-source option rather than a vegan one. The blend may appeal to shoppers who want a clear protein format and do not require all ingredients to be plant-based.
Because the formula includes more than one source, inspect the full ingredient and allergen panel if you are avoiding a particular animal ingredient or following a tightly defined diet. “Plant sources” in a product name or description does not change its non-vegan classification when beef is also present.
Barebells Protein Soda: carbonated, clear and milk-derived
Barebells describes its Protein Soda as a sugar-free sparkling soda. Its protein is clear whey isolate, a milk-derived ingredient. That makes it unsuitable for vegan and dairy-free diets despite matching the desired soda-like format.
It is relevant as a comparison because it demonstrates why format cannot be used as a shortcut for dietary compatibility. If you consume dairy and want carbonation, it may fit the category you are seeking; if you do not, the ingredient source rules it out.
Still alternatives when carbonation is optional
Alpro Soya No Sugars
Alpro Soya No Sugars is vegan, dairy-free and described as sugar-free. It is a soy beverage, not a carbonated protein soda or a clear-protein powder. Choose it when the dietary requirements matter more than fizz and you want a ready-to-drink plant beverage.
Rank #4
The available information does not state a protein amount or calorie figure for this comparison, so it should not be ranked against the protein-focused products on protein density. Use the current carton’s nutrition panel if those numbers are important to your decision.

PURIS’s formula sheet lists 10 grams of protein, 5 grams of prebiotic fiber and 5 grams of sugar in a 12-fluid-ounce can. That gives it a different selling point from the very-low-sugar formulas: it includes a stated fiber amount but carries more sugar than Koia Protein Pop.
The available formula information does not establish whether PURIS is vegan, dairy-free or what protein source it uses. Treat it as a potential option only after checking the current can for ingredients, allergen declarations and dietary certification. Do not infer plant-based status from the presence of prebiotic fiber.
Choose by the priority that matters most
If you require a vegan carbonated can
Start with Koia Protein Pop because it is the only option in this comparison explicitly presented as both vegan and carbonated in a ready-to-drink can. Check the current flavor label before purchase, particularly if you have an additional allergen restriction.
If the lowest stated sugar is the goal
Among the vegan products, Applied Nutrition Clear Vegan Protein reports less than 0.3 grams per 15-gram serving, while Rocka makes a no-added-sugar claim. For non-vegan dairy-free choices, Applied Nutrition Clear Protein Isolate and PVL ISO CLEAAR report zero sugar. Compare serving sizes rather than treating every “sugar-free” or “low-sugar” statement as equivalent.

Applied Nutrition Clear Protein Isolate reports more than 27 grams per serving, the highest stated amount in this group, but it is beef-based and not vegan. PVL ISO CLEAAR reports 20 grams. The vegan options list 13 grams for Rocka, more than 11 grams for Applied Nutrition Clear Vegan Protein and 10 grams for Koia Protein Pop in its can. These values come from different serving formats, so they describe label amounts rather than a standardized laboratory comparison.
Best Value

If calories matter alongside protein
Applied Nutrition Clear Vegan Protein reports 49 calories per 15-gram serving, Koia Protein Pop 70 calories per can, PVL ISO CLEAAR 80 calories per serving and Applied Nutrition Clear Protein Isolate 111 calories per serving. The comparison is meaningful only when you account for the serving actually consumed; adding extra powder or using a larger can changes the intake.
If you want a creamy-shake replacement
Clear proteins are designed to avoid the thick texture associated with many creamy shakes. The vegan powders from Rocka and Applied Nutrition are described as fruit-style clear drinks. Koia supplies that lighter experience in a carbonated can. A still soy beverage such as Alpro Soya No Sugars is another non-creamy option, but it is not a clear-protein soda.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to use a powdered clear-protein alternative
Powders require a little more preparation than canned soda. Follow the product’s own scoop and water directions, because the stated nutrition depends on the labeled serving.
- Verify the serving size first. Rocka’s stated comparison is 18 grams; Applied Nutrition Clear Vegan Protein’s is 15 grams. Use the scoop or a scale as directed rather than assuming one scoop equals one serving.
- Check the ingredient and allergen panel. Confirm that the protein is pea-based if you need vegan protein, and check for any flavor-specific declarations.
- Add the labeled amount of water. Water volume affects sweetness and intensity but does not change the powder’s listed nutrition when the full serving is used.
- Mix according to the package directions. Clear formulas are intended to produce a lighter, fruit-style drink. Allow any foam to settle if the label recommends doing so.
- Do not carbonate unless the product specifically permits it. A powder mixed with water is not automatically a safe substitute for a pre-carbonated can. If you want fizz, use a product designed and labeled for that format.
- Recheck the finished serving. Adding juice, sweeteners or a second scoop changes the sugar, calorie and protein totals shown in the table.
Pitfalls that lead to the wrong purchase
Mistaking “clear” for “vegan”
Clear whey is still dairy. Barebells demonstrates this directly, while beef isolates show that dairy-free can still be animal-derived. Identify the source—pea, whey, beef or a blend—before evaluating the rest of the label.
Comparing a can with a scoop as though they were the same serving
Koia’s figures apply to a 12-fluid-ounce can. Rocka and Applied Nutrition report grams of powder per serving, and the other isolates use their own serving definitions. A can may be consumed in one sitting while a powder serving can be adjusted by water volume, so compare both the stated serving and the amount you plan to drink.
Assuming a no-added-sugar claim means zero total sugar
Rocka’s claim concerns added sugar. Applied Nutrition Clear Vegan Protein gives a numerical total of less than 0.3 grams per 15 grams. Those statements answer slightly different questions. Use the nutrition panel when a medical, athletic or personal target requires a specific gram limit.
Ignoring regional and flavor differences
Nutrition panels, flavor names, allergen statements and availability can vary by country and can change when a formula is updated. The figures here are tied to the cited 2026 reports or product pages accessed in 2026. Confirm the exact package you will receive, especially when ordering online.

Words such as “plant,” “protein,” “sparkling” and “sugar-free” do not replace an ingredient list. For strict vegan or dairy-free diets, check the complete label and any certification mark, then consider shared-equipment warnings if cross-contact is a concern.
A practical decision path
- Set the non-negotiable diet rule. If vegan, exclude whey and beef. If dairy-free but not vegan, beef may remain acceptable; confirm that the specific product has no milk ingredients.
- Choose the format. Select Koia Protein Pop or another verified can if you need grab-and-go carbonation. Select Rocka or Applied Nutrition Clear Vegan Protein if mixing a powder is acceptable.
- Set the sugar ceiling. For the lowest stated vegan sugar, compare Applied Nutrition’s less-than-0.3-gram figure with Rocka’s no-added-sugar claim. For non-vegan dairy-free formulas, the listed zero-sugar options are Applied Nutrition Clear Protein Isolate and PVL ISO CLEAAR.
- Check the protein target and serving. Use the label amounts in the table, remembering that a powder serving and a 12-fluid-ounce can are different units.
- Confirm the exact package. Recheck ingredients, allergens, flavor, serving size and regional availability immediately before purchase.
Bottom line
Koia Protein Pop is the best direct answer to “vegan protein soda” because it combines a carbonated can with a vegan, dairy-free pea-protein formula. Rocka Clear Protein and Applied Nutrition Clear Vegan Protein are better fits when you can mix a powder and want a plant-based clear drink with no added sugar or very little stated sugar. Applied Nutrition Clear Protein Isolate and PVL ISO CLEAAR serve dairy-free shoppers who accept animal-derived or mixed protein, while Barebells is a reminder that clear carbonation does not make a product vegan. Choose by protein source first, then compare the serving-specific sugar, calories and format on the current label.
