The Best Protein Sodas of 2026, Ranked by Math and Honest Taste Reports
In a hurry? Best protein per dollar is Bucked Up (25g). The best-reviewed soda flavors belong to SkyPop, but read the note below first: the tests that earned it that were run on the old 15g can. Cheapest of all: make it at home for ~$1.
Check Bucked Up price See the full rankingProtein soda went from one struggling brand to a crowded shelf in about eighteen months. The pitch is simple: a fizzy can that drinks like soda and carries 10 to 30 grams of protein, no blender, no chalk. The catch is just as simple: a lot of them taste bad, and the ones that taste fine often carry the least protein.
We have not run our own blind taste test yet, so we won't pretend we did. What we can do is the math nobody prints on the can (protein grams per dollar), lay out the sweetener and caffeine fine print, and tell you what the two most thorough published taste tests, from Tasting Table and Sporked, actually concluded. Their verdicts disagree in interesting ways, and that disagreement is the most useful information in this category.

1. Bucked Up Protein Soda: Most Protein for Your Money
Bucked Up Protein Soda, 25g, ~$40 per 12-pack
Bucked Up put 25 grams of clear whey isolate in a 16 ounce can with zero sugar and no caffeine, and at roughly $3.33 a can that works out to about 7.5 grams of protein per dollar, the best ratio of anything on this list you can actually order online. Eight flavors: Banana Pineapple, Peach Mango, Orange Cream, Cherry Limeade, Green Apple, Rainbow Candy, Frosted Lemonade, and Berry Punch.
Here is the honest part. Taste reports are split by flavor, hard. Tasting Table's tester ranked Bucked Up Orange Cream second best of eleven protein sodas, saying it genuinely tasted like an orange creamsicle, and ranked Bucked Up Peach Mango dead last, citing an overwhelming fake sweetness. Same brand, same formula base, opposite ends of the ranking. If you try Bucked Up, flavor choice is not a detail. Start with Orange Cream.
Pros
- 25g protein, the most of any widely available protein soda
- Best protein-per-dollar math in the category
- Zero sugar, zero caffeine, lactose free
- Widely stocked: Amazon, Walmart, GNC, brand site
Cons
- Flavor quality varies wildly can to can (Orange Cream praised, Peach Mango panned)
- 16 oz is a lot of liquid if you don't love the flavor
- Sweetened with sucralose, which some people taste immediately
2. SkyPop Protein Soda: The One That Tastes Like Soda
SkyPop Protein Soda, 10g, ~$2.25 per can
Note, August 2026: this brand used to be Don't Quit!, Jake Steinfeld's "Body by Jake" line, and we ranked it here at 15 grams a can. It rebranded to SkyPop in early 2026 and reformulated at the same time, down to 10 grams and 45 calories. We have kept it in this slot and changed what the slot claims, because the reason it earned the spot no longer has evidence behind it. See below.
SkyPop makes the opposite bet from Bucked Up: less protein, classic soda flavors. Root Beer, Orange, Grape and Fruit Punch carried over from the old line, and Ice Pop, Strawberry Cotton Candy and Peaches & Cream are new. 10 grams per 12 ounce can, zero sugar, no caffeine, 45 calories. Amazon sells a 12-pack at $26.98, about $2.25 a can, which is roughly 4.4 grams of protein per dollar. That is well behind Bucked Up but still ahead of Barebells and Waay, which are also 10 grams and cost more per can.
Here is the part that matters, and it is why the badge on this card changed. The taste reports that made this brand famous were run on the discontinued 15 gram can. Tasting Table ranked Don't Quit! Root Beer the single best protein soda of eleven tested, saying it could pass for a regular sugar-free root beer, and put the Orange fourth, a dead ringer for classic orange soda. Sporked scored the Grape 6.5 out of 10, carbonated Welch's. Those verdicts were about a different formula. No published blind test of SkyPop exists that we could find. The flavor names and the brand are the same, the recipe is not, and we are not going to lend a 15 gram can's reviews to a 10 gram one. Treat this as the most promising unproven soda on the list rather than the proven best-tasting one.
Pros
- Classic soda flavors instead of candy flavors, and the recipe philosophy carried over
- Cheapest per can here at ~$2.25, and better g/$ than Barebells or Waay
- Zero sugar, zero caffeine, 45 calories
- Wide retail: Target, Walmart, Kroger, Albertsons, CVS
Cons
- 10g is a snack, not a meal's worth of protein, and it used to be 15g
- Every published taste verdict on this brand is about the old formula
- On Amazon only the Orange 12-pack is in stock right now; Root Beer, Grape and Ice Pop show as not currently shippable
3. Barebells Protein Soda: The Safe Pick With a Caffeine Surprise
Barebells Protein Soda, 10g, ~$36 per 12-pack
Barebells makes the protein bars everyone actually finishes, and its soda line carries that same "pleasant, not extreme" DNA. Flavors include Classic Cola, Wild Strawberry, Sweet Cherry, and Pineapple Sunrise, 10 grams of protein per 12 ounce can. Sporked scored Pineapple Sunrise 7 out of 10 and Wild Strawberry 7.5 out of 10, among the best results in its 18-soda test, noting less of the drying aftertaste that plagues the category.
The fine print matters here twice. First, 10 grams at $3 a can is weak protein math, about 3.3 g/$, half of what Bucked Up delivers. Second, caffeine. Every Barebells Protein Soda flavor carries 200mg of caffeine, more than two cups of coffee, and the brand says so on each can and on each product page: Classic Cola, Pineapple Sunrise, Sweet Cherry and Wild Strawberry all read "CAFFEINE 200mg" on the label. There is no caffeine-free Barebells soda. Do not hand one to a teenager and do not drink one at 9pm.
Pros
- Among the best scores in Sporked's 18-soda taste test
- Less chalky aftertaste reported than most rivals
- Trusted brand with wide retail distribution
Cons
- Only 10g protein, weak grams-per-dollar
- Every flavor carries 200mg caffeine, there is no decaf option
- Third-party seller holds the Amazon buy box, so the price moves without notice
4. Waay Sparkling Protein: Best If You Hate Sucralose
Waay Sparkling Protein Drink, 10g, ~$40 per 12-pack
Waay's whole identity is what it leaves out: no sucralose, sweetened with stevia and monk fruit instead, 10 grams of clear whey (plus collagen in some flavors), 45 calories, zero sugar, no caffeine. Flavors are citrus-forward: Grapefruit, Lemon Raspberry, Orange. It launched at Whole Foods in late 2025 and now sits in Target, Sprouts, and Amazon.
Sporked named Waay Grapefruit the best protein soda of all 18 it tested, at 8 out of 10, calling it the least offensive of the bunch thanks to the bitter grapefruit edge cutting the sweetness. That is a backhanded crown, but in this category it counts. The trade-off is the math: 10 grams at $3.33 a can is the weakest protein per dollar on this page.
Pros
- Grapefruit was Sporked's #1 of 18 protein sodas tested
- No sucralose, if that's your dealbreaker
- Light 45-calorie cans, citrus flavors that don't pretend to be dessert
Cons
- Only 10g protein, ~3 g/$ is the worst value here
- Stevia aftertaste still present per reviews, just milder
- Premium price for the least protein
5. Protein Pop Plus: The 30-Gram Costco Play
Protein Pop Plus, 30g, Costco nationwide
Launched at all 600+ US Costco locations in early 2026, Protein Pop Plus packs 30 grams into a 12 ounce can using a blend of whey isolate and bovine collagen. That is the highest number in the category. One honest flag on the label: collagen is an incomplete protein, so not all 30 grams are equal to whey grams for muscle purposes. We break that down in the full review.
Correction, August 2026: we had this down as a Costco-only buy. It is not any more. Protein Pop Plus is now sold on Amazon as well, at $41.99 for a 12-pack of the Citrus flavour, and direct from the brand. Costco is still the cheaper route per can if you have a membership, and warehouse pricing varies by region, but you no longer need one to try it. Genius Gourmet's Blue Raspberry Lemonade (30g) plays the same role and got a friendly seventh-place writeup at Tasting Table, described as candy-like and closer to an energy drink than a soda.

Fizzique Sparkling Protein Water, 20g, availability spotty
Fizzique invented this category back in 2018 with 20 grams of hydrolyzed whey in a sparkling can, years before anyone cared. As of mid 2026 its status is murky: BevNET's brand database lists it as no longer on the market, while some retailers still show stock. We keep it here for one reason: if you see it cheap on a closeout shelf, 20 grams per can is real, and it proves how fast this category eats its pioneers.
Update, August 2026: we checked, and there is nothing left to link to. Amazon's Fizzique listing reads "Currently unavailable" with no other sellers behind it, and a search of Amazon's catalogue returns no Fizzique product of any kind. We have removed the buy button rather than send you to a dead page. Closeout shelves and clearance racks are the only realistic route, and BevNET looks right.
Our Verdict
Buy Bucked Up if protein is the point. 25 grams at the best price per gram, just choose flavors carefully (Orange Cream, not Peach Mango).
Buy SkyPop Orange if you're replacing a soda habit and you accept that you are the test. It is the flavor Amazon currently has in stock, and the old 15g Orange was the second-best thing either published test tried. If you want Root Beer specifically, check Target or the brand's store locator; Amazon lists it but is not shipping it.
Buy Waay if sucralose ruins everything for you, and treat the protein as a bonus, not the meal. Grab Protein Pop Plus on your next Costco run if you want maximum grams and understand the collagen asterisk.
How We Evaluate: The Can Math Method
Every ranking on this site runs through the same four steps. We call it Can Math, and it is the reason our order sometimes disagrees with the taste-test blogs.
- Read the label, not the front. Protein source (whey isolate vs a collagen blend), sweetener, caffeine, calories. A padded 30g can lose to an honest 25g one.
- Verify the price the day we write. Real retail cost from Amazon, Walmart, or the brand shop, with the date noted on the page.
- Divide: protein grams per dollar. The one number no can prints, and the one that actually ranks these.
- Attribute the taste, never fake it. Flavor verdicts come from named tests (Tasting Table, Sporked) until we run our own with photos. No invented first-person sips.
Rankings never change based on commission rates. More on the about page.
