Protein Soda: 7 Sparkling Drinks Compared by Protein and Cost

Protein soda can provide useful protein in a lighter, fizzy drink. The important detail is where that protein comes from. A can containing whey isolate, a whey-and-collagen blend, and a plant-protein soda can carry similar front-label promises while offering different buying tradeoffs.

Our starting pick is Premier Protein Sparkling Protein Soda for an accessible whey-only top-up at the verified price below. Bucked Up is the more substantial whey-only serving. Koia Protein Pop is the plant-based choice. None needs to replace a meal, and bubbles do not give protein special muscle-building powers.

Research checked October 27, 2026. This is a label-and-price comparison of seven commercially listed sparkling drinks, not a hands-on protein soda review or taste test. Prices are U.S. snapshots before tax and shipping; availability and formulations can change. Unverified fields remain marked rather than estimated.

What is protein soda, exactly?

Protein soda is a carbonated drink with added protein, usually designed to resemble a soft drink or sparkling fruit beverage rather than a creamy shake. The name is a shopping category, not proof of a particular protein dose, ingredient profile, or nutritional completeness.

Read the back of the can. Some sparkling protein drinks use whey isolate from milk. Others blend that whey with bovine collagen. Koia uses clear pea protein. A zero-sugar energy drink without protein does not qualify, and a clear protein water is not necessarily carbonated.

One particularly easy naming trap: Protein Pop's own website distinguishes its noncarbonated 22g original from its lightly carbonated Plus and Balance products. The 22g original is excluded from our seven. Koia's similarly named Protein Pop is a separate plant-based product.

Why sparkling protein drinks are getting attention

The format addresses a practical objection: some people want extra protein without another thick chocolate or vanilla shake. It also lets a familiar afternoon soda occasion double as a protein snack. That convenience can matter more to adherence than another marginal change in supplement marketing.

There is evidence of expanding supply, rather than a verified market-growth percentage here. Protein Pop announced a nationwide Costco expansion in February 2026, and Premier Protein announced its sparkling soda in August 2026. These launches explain why shoppers are encountering the category; they do not prove it outperforms shakes.

Seven protein soda drinks compared

Figures refer to the named product and serving. “Not verified” means we could not establish that field from the reviewed sources. The table is intentionally not sorted as a muscle-growth league table: collagen-containing totals are not interchangeable with whey-only totals.

Method: cost per can = pack price ÷ can count. Cost per 10g = pack price ÷ total labeled protein grams in the pack × 10. Calculations use unrounded inputs, then round to cents. These are product costs, not delivered costs or amino-acid-adjusted scores. No Amazon price has been copied into this comparison.

For example, Premier costs $8.99 ÷ 4 = $2.2475 per can, and $2.2475 ÷ 15 × 10 = $1.4983 per 10g. Protein Pop Plus costs $1.17 per 10g of its combined proteins, but about $2.33 per 10g of its declared whey portion. That second calculation does not say collagen has no value; it reveals why the headline total needs context.

What each drink offers—and the catch to check

1. Premier Protein Sparkling: our overall starting pick and whey-value pick

The Lemon Lime listing verifies the table's nutrition and four-pack price. Its full ingredient list is carbonated water, whey protein isolate, cane sugar, natural flavors, and stevia extract. It contains milk.

The appeal is a useful top-up without buying a large case. Among the verified whey-only prices here, it has the lowest cost per 10g. The tradeoff is 3g sugar and a smaller serving than Bucked Up. “Best overall” means our most practical starting purchase, not a taste or clinical superiority award.

2. Bucked Up: best for a larger whey-only serving

The current brand listing specifies 25g whey isolate, 100 calories, no sugar, and no caffeine in a 16oz can. Listed ingredients include carbonated water, whey isolate, natural and artificial flavors, citric and malic acids, sucralose, acesulfame potassium, potassium sorbate, and sodium benzoate. It contains milk.

The larger whey dose is its reason to buy. The drawback is a roughly $96 upfront commitment for the verified 24-can offer. Do not confuse the protein soda with Bucked Up energy drinks, or use an energy-drink bundle price to calculate an all-protein case.

3. SkyPop Grape: a small whey top-up, with price still to check

SkyPop's Grape page confirms 10g whey protein, 45 calories, zero sugar, and no caffeine. Ingredients include carbonated water, whey isolate, citric and malic acids, natural flavors, vegetable juice for color, sucralose, and mushroom extract. It contains milk.

That makes it relevant to someone seeking soda-style refreshment with a modest protein addition. We verified the linked Amazon product identity but did not establish a dependable current price, so it cannot win a value ranking.

4. PRODA Classic Orange: a low-calorie whey option

PRODA's product page supplies the $39.95 twelve-can price. Its brand FAQ confirms 10g whey isolate, 40 calories, no sugar, and no caffeine. It contains milk despite being described as lactose-free.

The FAQ identifies stevia and monk fruit for Strawberry Lemonade, but that is not an exact ingredient list for Classic Orange. We have not copied one flavor's formulation onto another. Check the Orange can's full label. At the observed price, its case costs over twice Premier's price per 10g; preference would need to justify that difference.

5. Koia Protein Pop: best for a vegan sparkling option

Koia Rocket Freeze uses clear pea protein and includes 4g fiber. Its listed ingredients are carbonated water, clear pea protein, chicory root fiber, natural flavors, organic cane sugar, citric and malic acids, organic stevia extract, fruit and vegetable juice for color, and monk fruit extract.

It is the clear choice here for avoiding animal-derived protein. The practical limitation is dose: 10g is a supplement to the day's food, not a large recovery meal. The price is also a convenience premium. Consider your tolerance for the fiber and sweetener combination before ordering multiple cases.

6. Protein Pop Plus: a transparent whey/collagen split

The manufacturer FAQ explicitly separates the 30g total into 15g whey isolate and 15g bovine collagen. The Citrus twelve-pack listing shows $41.99 and zero sugar. It is lightly carbonated and contains milk-derived protein plus bovine collagen.

The exact Citrus calorie panel and full ingredient list were not verified in the reviewed text. The site's 90–100 calorie statement concerns the standard 22g product, so we have not applied it to Plus. Confirm the can label and stock before ordering; the listing also presents a coming-soon link. Its disclosed split is useful, but 30g total should not be described as 30g whey.

7. Genius Gourmet Citrus: lowest labeled-protein cost, with a blend caveat

The Target Citrus listing verifies $2.99, 30g total protein, 130 calories, and zero sugar. Ingredients include carbonated water, whey isolate, bovine collagen peptides, malic, citric, and phosphoric acids, natural flavors, sucralose, sodium benzoate, and potassium sorbate. It contains milk.

It is the cheapest verified option per 10g of labeled protein in this comparison. The whey-to-collagen ratio is not disclosed in the reviewed listing, however, so we cannot calculate its whey-only value or assume it matches Protein Pop Plus. Buy it for a blend you want, not an imagined amount of whey.

Whey, collagen, and plant protein: what matters for muscle growth?

Whey provides essential amino acids and is well established in sports-nutrition research. For healthy exercising adults, the International Society of Sports Nutrition position stand gives a broad daily range of 1.4–2.0g protein per kilogram of body weight and commonly discussed servings of 20–40g high-quality protein. These are general ranges, not an individual prescription or a claim that smaller servings are wasted.

Collagen is not nutritionally interchangeable with whey. In a randomized trial in healthy older women, whey stimulated muscle protein synthesis more effectively than collagen. That population-specific result supports caution about swapping proteins gram for gram; it does not measure these sodas or prove long-term outcomes for every athlete.

A separate study in young men found benefits to protein synthesis from a blend containing 25g whey and 5g collagen compared with a noncaloric placebo. It did not test a 15g/15g soda against 30g whey. You cannot transfer its results to any can simply because the can contains both proteins.

Plant protein can contribute to total intake. The practical questions are the serving size, amino-acid profile, and the rest of your diet. Koia's 10g pea-protein serving has not been shown here to be equivalent to Bucked Up's 25g whey serving for recovery. For a vegan buyer, fit within the overall diet matters more than trying to make those two labels identical.

Protein soda vs protein shake: when is the premium worthwhile?

Choose sparkling when you prefer the format enough to use it consistently. Choose a conventional shake, powder, or food when it better meets your protein needs and budget. Neither texture earns extra credit for muscle growth; training, sufficient food, and an adequate overall intake remain the foundation.

At the observed Premier price, one can daily for 30 days costs about $67.43 before tax. PRODA's equivalent product cost is about $99.88. That is a meaningful recurring purchase for a drink providing only part of your daily protein.

Use our high-protein foods ranked by protein per dollar and protein coffee cost comparison to compare other ways of filling the same gap. Spending more is defensible when convenience helps; buying protein you do not need is not automatically an upgrade.

No best-taste award: we have no controlled tasting evidence that establishes a winner across these seven. Manufacturer flavor descriptions and retailer star averages are not comparable tasting results. Try a single can or the smallest practical pack before choosing a subscription.

Frequently asked questions

Does carbonation destroy the protein?

Fizz is not a reason to disregard the labeled protein, and it is not evidence of improved absorption. Judge the protein source and quantity. No trial reviewed here establishes that carbonating these drinks makes them better for muscle growth than a comparable noncarbonated serving.

Can I drink protein soda after a workout?

Yes, it can contribute protein. A 10g can may be a top-up alongside food rather than your whole recovery intake. Consider the complete meal and the rest of the day, rather than buying multiple cans just to hit one particular post-workout number.

Are sparkling protein drinks dairy-free?

Most in this comparison contain milk-derived whey, even when described as lactose-free. Lactose-free does not mean safe for a milk allergy. Koia identifies its Protein Pop as vegan; always check the current allergen label.

Is protein soda an energy drink or meal replacement?

Neither by default. Check caffeine separately and do not mistake a brand's energy line for its protein soda. These drinks do not provide the balance of a complete meal. Follow package opening instructions and do not vigorously shake a carbonated can.

The verdict: buy the protein you want, then choose the bubbles

Start with Premier for a modest, well-priced whey top-up, Bucked Up for a larger whey-only serving, or Koia for a vegan sparkling choice. Consider the blends when you want their actual composition. The best protein soda is one that fills a real dietary gap at an acceptable cost—not simply the can with the largest number on the front.
