Our Picks at a Glance
How To Choose The Best Clear Whey Protein Isolate
Choosing a clear whey protein isolate isn’t just about picking a fruit flavor you like. The real differences between these powders show up in how they mix, how they taste, and what else is in the tub besides protein. Here is what actually matters when you compare them side by side.
Check the protein and calorie math first
Every clear whey on this list uses an isolate, which filters out most of the fat and lactose. The number that decides your value is protein per serving against total calories. You will see 20g to 22g of protein per scoop across these picks, with calories ranging from 80 to 100 per serving. A powder that hits 20g of protein in just 80 calories leaves more room in your daily budget than one that needs 100 calories to deliver the same protein.
Mixability is the real test of a clear whey
A clear whey that clumps or foams endlessly defeats the entire point of a refreshing drink. You want a powder that dissolves cleanly in cold water with a quick shake. Many owners fix stubborn clumps by adding ice, using a hand frother, or letting the foam settle for a few minutes — but a powder that needs a blender just to become drinkable will frustrate you on busy mornings.
Know what is inside the tub
Clear whey formulas vary beyond the protein itself. Some add digestive enzymes or collagen peptides, some are sweetened with stevia instead of sucralose, and others are certified gluten-free or Informed Sport certified. If you are sensitive to lactose or artificial sweeteners, check the ingredient list for these details before you commit to a full tub.

In‑Depth Reviews
1. Oath Nutrition Clear Whey Isolate — Coconut Colada
Our pick — over 4.5★ from 750+ verified ratings; the strongest balance of quality and price.
A tropical coconut colada flavor that delivers 20g of grass-fed protein with no added sugar.
Oath’s Coconut Colada is the clear whey that finally delivers on the “drinks like juice” promise. This grass-fed whey protein isolate packs 20g of complete protein per serving with no added sugar, built for sipping during a workout or by the pool. The crowd favorite is the Piña Colada flavor — described as a perfect match with no bitter aftertaste or grit.
The 21-serving bag gives you a full protein routine, and owners praise its versatility beyond just a drink. It holds up beautifully in a Ninja Creami for protein ice cream, mixes into cocktails, and even works as a topping sprinkled over fruit. The trade-off is that mixability gets mixed feedback — some find it super smooth while others deal with clumps. A simple fix owners swear by is frothing the powder in a small amount of water first before adding the rest.
Owners also note it doesn’t upset their stomach, a common concern with protein supplements. One buyer summed it up: “This taste so good. It is rather clumpy and difficult to mix but I don’t have a problem with it. It doesn’t upset my stomach and its light and refreshing.” With 755 ratings and a 4.7-star average, it is the highest-rated pick on this list — the clear choice for anyone who wants a genuinely delicious, refreshing protein drink.
Why It Wins Fans
- Piña Colada flavor earns the highest praise — taste is what wins people over
- 20g of grass-fed protein with no added sugar
- Versatile for smoothies, protein pops, and cheesecake recipes
The Mixing Caveat
- Clumpy texture reported by some, needs a frother or pre-mix trick
- No bulk sizes available
Your best bet if: you prioritize flavor and want a protein that tastes like a tropical treat rather than a chore.
Think twice if: you want a zero-effort mix — this one may require a little technique to get perfectly smooth.
2. Bloom Nutrition Clear Whey — Strawberry Watermelon
A strawberry watermelon flavor with 5g of collagen peptides for added beauty benefits.
Bloom’s Strawberry Watermelon clear whey stands out because it brings more than just protein to the glass. Each serving delivers 20g of total protein — with 15g coming from whey protein isolate — in just 90 calories, plus 5g of collagen peptides and digestive enzymes to help nourish hair, skin, and nails while you recover. It is a well-rounded wellness drink rather than a bare-bones protein supplement.
The flavor is the headline here. Owners are quick to say it tastes like a melted Jolly Rancher or Now and Later candy, with a light, juice-like texture that is not thick and mixes well. Buyers report letting the foam settle for a few minutes after shaking for the perfect glass. The brand was founded by Mari Llewellyn, who wanted quality supplements that actually taste good.
Be realistic about the numbers: at just 10 servings per tub, this is a sampler-sized container. For a comparable amount of protein, the Oath Nutrition option holds a 2.1x servings advantage — 21 servings versus 10 — making Bloom the pricier per-drink choice. Also, a few owners find it dissolves slowly and leaves clumps, and some note it comes out cloudy rather than crisp. If you want a single-scoop treat with collagen benefits, this is a solid pick; if you need a daily staple, the larger tubs stretch further.
Best as: a refreshing post-workout or between-meal drink for anyone who wants collagen and digestive enzymes bundled with their protein.
The honest trade-off: the 10-serving tub delivers a lower protein dose per scoop than rivals, so your grams per serving are less efficient here.
3. Ascent 100% Clear Whey — Pineapple Coconut
A clean, Informed Sport certified formula with 2.1g of leucine and no artificial ingredients.
Ascent’s clear whey is built for athletes who care about what goes into their bodies. It delivers 20g of clean protein per serving with 2.1g of leucine — the amino acid that triggers muscle protein synthesis — in only 100 calories. The formula is certified gluten-free and Informed Sport certified, with no artificial flavors or sweeteners. That clean ingredient list is a major reason owners choose it over other clear wheys.
The flavor is pineapple-forward with a subtle coconut finish, and owners mention it is not overly sweet. It blends easily without bloating, and some note it is genuinely better than protein/collagen drinks they have tried. The main catch is that it requires patience: the powder foams and clumps heavily at first. Owners have found adding ice and extra water, then waiting about 10 minutes for the foam to settle, fixes it.
Reviewers who have tried multiple brands call this the best clear whey they have tried, praising the clean ingredients and easy drinkability. It also comes in a lighter package — 1.14 pounds — which is 18% lighter than the Oath Nutrition bag, making it a touch easier to store. For anyone who wants a trusted, competition-tested protein without artificial sweeteners, this is the one to beat.
What Owners Love
- Clean 3-4 ingredient list, no sucralose or artificial flavors
- Informed Sport certified and certified gluten-free
- No bloating or stomach upset
What Needs Patience
- Foams and clumps heavily — plan for 10 minutes of settling time
- Fine powder that can be messy to scoop
Reach for it if: you are an athlete who values third-party certification and a short, clean ingredient list over instant mixing.
Look elsewhere if: you need a grab-and-shake drink with zero waiting time.
4. Myprotein Clear Whey Isolate — Peach Mango
A low-calorie option at 80 calories per 20g serving, ideal for strict diets.
If your macro budget is tight, Myprotein’s Peach Mango clear whey gives you the most protein per calorie here. Each serving packs 20g of protein from hydrolyzed whey in only 80 calories, with zero fat and zero sugar. It is a gluten-free formula designed to help grow and maintain muscle without derailing a strict diet, and it drinks like a fruity juice rather than a milky shake.
The flavor draws comparisons to peach ring candies, though some owners find a slightly bitter aftertaste that fades quickly. It mixes best with vigorous shaking or a quick 10-15 second blend in a NutriBullet; a standard shaker alone may leave chunks. A recurring theme in reviews is that the taste is polarizing — some love it, while others find it overly sweet and hard to dissolve.
That said, owners who hate traditional protein drinks often find this their go-to alternative. It works as a mocktail base, and the container is light at 1.3 pounds. If you want the leanest, most diet-friendly clear whey and are willing to use a blender, this delivers a huge protein bang for your caloric buck. Just be ready to experiment with your mixing method.
Strongest for: cutters and calorie-counters who want 20g of protein for just 80 calories without sacrificing a fruit-forward taste.
The catch: mixability is inconsistent — a blender or shaker bottle is almost mandatory to avoid clumps.
5. Optimum Nutrition Pro Quench — Orange Mango
A 3-in-1 drink combining 20g protein with electrolytes for hydration support.
Optimum Nutrition takes a different angle by making its clear whey a 3-in-1 sports drink. Each serving combines 10g of clear whey protein isolate with 10g of collagen peptides and electrolytes, giving you a total of 20g of protein alongside hydration support to replace what you lose through sweat. It is a light, smooth, fruit-flavored alternative to thick shakes, with 0g sugar and under 100 calories per serving.
The Orange Mango flavor gets described as sweet and refreshing, with a smooth, non-grainy texture that reminds some owners of expensive health drinks. It does not leave a bad aftertaste, which is a common pitfall in this category. The electrolyte addition makes it especially popular with runners and anyone who wants hydration and protein in one bottle. One reviewer noted it helps with both electrolyte and protein intake.
The honest downside is mixing. Customers note it doesn’t dissolve completely, and it can clump — one buyer found clumps 6 out of 10 times when using a hand shaker and had to shake for more than 20 seconds. Others report foaming, which is listed as a negative aspect. To get the best results, mix it in a small container with ice and let the foam settle. For active people who want a multi-tasking drink, this is a smart pick; for anyone who hates fussy mixing, the foaming will test your patience.
Perfect for: runners, gym-goers, and active lifestyles that want protein plus electrolyte replenishment in one lightweight drink.
The trade-off: heavier foaming and occasional clumps — count on using ice and waiting for the fizz to settle.
6. RYSE Clear Protein — Variety Pack (12-Pack)
A ready-to-drink bottle with 22g of protein, no mixing required.
If you dread the ritual of scooping, shaking, and waiting for foam to settle, RYSE solves it by delivering 22g of ultra-filtered whey isolate in a ready-to-drink 16.9 fl oz bottle. No mixing, no clumps, no cleanup — just a crisp, juice-like protein drink that is sugar-free, lactose-free, and contains only 100 calories. It is the easiest way to get fast-digesting protein support on the go.
Owners consistently praise it as a great source of protein that is easy to drink and doesn’t cause stomach issues. The 12-pack variety lets you sample four different flavors, and one buyer mentioned it is suitable for clear liquid diets — a niche but genuinely important use case. The texture is not chalky like milk-based products, which is exactly why people switch to clear whey in the first place.
There are trade-offs to the convenience. Some owners find the sweetness level too high, and there are mixed reports on the flavor — one buyer loved it, another found it had a weird chemical-like taste and was way too sweet. You also carry the weight of the liquid: at 15.08 pounds for the case, this is the heaviest option on the list, though that is the cost of pre-mixed convenience. If you want the absolute easiest path to 22g of protein with zero prep, this is it.
The Convenience Win
- Zero mixing — it is already perfectly blended in the bottle
- 22g of whey isolate with only 100 calories
- Lactose-free and easy on the stomach
The Bottle Drawbacks
- Heavier to carry — a full case weighs 15.08 pounds
- Sweetness level is divisive among buyers
Choose it if: you travel, commute, or simply hate the mixing process and want protein with zero effort.
skip it if: you prefer controlling your own sweetness levels or need a lighter package for your gym bag.
7. JYM Supplement Science Iso JYM — Bombsicle
An ultra-cold filtered isolate with a 6-ingredient formula that mixes clear.
Iso JYM is the pick for supplement purists who want a whey-only product with nothing extraneous. It uses an ultra-cold filtration process to deliver 20g of pure whey protein isolate per serving, mixes clear, and comes in at just 90 calories with zero fat and zero sugar. The formula contains only 6 ingredients — a remarkably short list that shows the focus on clean formulation.
The Bombsicle flavor is designed to taste like your favorite thirst-quenching drink rather than a protein shake, with a crisp, light mouthfeel. Some owners find it delicious, describing it as light and refreshing compared to thicker shakes, and ideal right after a workout. The 20g of protein per serving is solid, and the drinkability gets positive feedback for being easy to get down.
The trade-off is that flavor and mixability are genuinely mixed. The Bombsicle taste is polarizing — some call it delicious while others find it sickeningly sweet, and one buyer described it as tasting like medicine. You may need to use more water to dilute the sweetness. The clumping is also a known issue; it requires immediate shaking or blending, and some owners recommend letting it sit for 30 minutes with frequent shaking. If you want a stripped-down, high-quality isolate and don’t mind coaxing it to mix, this delivers on purity.
Best for: experienced lifters who want a minimal-ingredient, whey-only isolate that mixes clear and supports lean muscle.
Worth knowing: the Bombsicle flavor is divisive, and mixing requires real effort — a blender helps a lot.
8. Myprotein Clear Whey Isolate — Lemonade (35 Servings)
A 35-serving tub with a lemonade flavor that owners love for daily use.
For sheer volume, this 35-serving tub of Myprotein Lemonade is the value king of the list. It delivers 20g of protein per serving from hydrolyzed whey, with only 90 calories, zero fat, and zero sugar. If you plan to drink clear whey every single day, this larger size means fewer reorders and a lower cost per serving over time.
The flavor is the standout — owners say it tastes just like lemonade, and it has earned the title of the only protein one buyer was actually able to finish, with seven jars purchased. It dissolves well in water, though it is foamy, and it is gluten-free and lactose-intolerant friendly for many. Reviewers point out no stomach issues and describe the texture as a smooth lemonade drink rather than a milky shake.
The recurring complaints are foam and chunks. Even with different mixing methods, some owners deal with excessive foam and occasional clumps, and a few find it too sweet. The simple fixes include blending 24oz of water and refrigerating overnight, or adding extra water with lemons and limes. If you want the best per-serving value in a flavor that people genuinely love, this big tub is hard to pass up.
Why It’s a Daily Driver
- 35 servings — the biggest tub on this list
- Lemonade flavor compares to a commercial lemonade drink
- 20g protein at 90 calories with zero sugar
The Foam Factor
- Excessive foaming is the main complaint
- Chunks can persist for some, even with a blender
Pick it if: you want the most protein per tub and a crowd-pleasing lemonade flavor for everyday drinking.
Be aware: you will likely be waiting for foam to settle — this is not a quick-gulp drink.
9. Clean Simple Eats Clear Protein — Sour Candy Watermelon
The candy-flavored premium that proves clean ingredients can still taste like a treat.
Clean Simple Eats is the premium end of the clear whey spectrum, and for many owners it is worth every extra dollar. Each serving packs 20g of ultra-filtered whey protein isolate with a complete amino acid profile that is fast-absorbing and gentle on digestion. The formula is gluten-free and soy-free, with zero added sugars and no artificial flavors, sweeteners, or dyes — it is naturally sweetened instead.
The Sour Candy Watermelon flavor is the star attraction. Owners say it truly tastes like the sour watermelon candy it mimics, and it is a favorite for anyone who misses the fun of a fruity drink. The texture gets positive feedback too, described as super smooth and easy to drink, mixing well with a shaker bottle and not needing a blender. It has become the go-to for many as the easiest protein supplement to stick with.
There are a few honest caveats. Some owners find it hard to dissolve, and opinions on value are divided — it is more expensive than other clear wheys. One buyer with lactose sensitivity found it was not gentle on their stomach despite being labeled low lactose. If you prioritize ultra-clean ingredients and adore watermelon candy flavor, this is the top-shelf choice, just budget accordingly.
Splurge on it if: you want the cleanest naturally-sweetened formula and a sour watermelon flavor that owners genuinely love.
The honest note: it commands a premium price, and those sensitive to lactose should approach with caution.
Understanding the Specs
Whey Protein Isolate vs. Concentrate
Isolate is the more heavily filtered form of whey, stripping away most of the fat and lactose to leave a purer, faster-absorbing protein. That is why clear whey leans on isolate — the cleaner profile mixes into a translucent drink instead of a milky one. If you are lactose-sensitive, isolate is usually the safer bet.
The Mixability Equation
A clear whey’s texture depends on how well the powder dissolves in cold water. Clumping and foaming happen when the powder hits water too fast or the formula lacks a dissolving agent. Small tricks — frothing the powder in a little water first, blending, or letting the drink sit for 10 minutes — solve most clumping issues without changing the drink’s nutrition.
