Our Picks at a Glance
How To Choose The Best Clean Clear Protein
Clear protein powders are whey protein isolates processed to be completely translucent when mixed with water. That means no milky look, no heavy mouthfeel — just a light drink that packs a protein punch. Here is what separates a great one from a regretful purchase.
Protein Per Scoop vs. Total Servings
The tub size is a distraction — what matters is how many servings you get and how much protein lands in each scoop. Most clear proteins hit 20g per serving, but a few go higher to 25g. Multiply the two numbers to see what you are actually buying for the price.
Mixability and Foam Level
All clear proteins foam when shaken — it is a natural trait of the isolate. The best ones settle within a minute or two into a smooth, crisp drink. If reviews consistently mention lumps or foam that takes forever to fade, that is a flag the powder does not dissolve easily.
Sweetness and Aftertaste
Because clear proteins skip the milk fats, flavoring is more exposed. Some brands use intense fruit flavor that hits like a liquid candy, while others lean subtler. The real test is whether the sweetness cloys after a few sips or leaves a bitter protein aftertaste — the reviews will tell you fast.

In‑Depth Reviews
1. GHOST Clear Whey Isolate Protein Powder, Blue Raspberry
Our pick — over 4★ from 800+ verified ratings; the strongest balance of quality and price.
You get 25g of protein per scoop — 5g more than most clear proteins here — without any fat or sugar.
That extra protein (25g vs. the usual 20g) means the GHOST tub delivers 20 servings of a sugar-free, soy-free formula that fits tightly into macro-conscious diets. Buyers report the Blue Raspberry flavor “tastes like light, fruity sports drink, not thick shake,” so it drinks like a refreshment rather than a chore. The Isopure Clear Whey (5 ingredients) has a simpler label, but GHOST packs more protein per gram of powder.
The sweetness is intense. Several reviews mention needing to mix a single scoop with at least 20-24 ounces of water to avoid an overpowering sugary hit. There is some foaming and minor clumping when you first shake it, but letting it sit for a couple of minutes resolves most of it. The 1.57-pound tub is relatively compact — about half the footprint of the Isopure Clear Whey container (11.61 x 6.3 x 10.63 inches) — so it stores easily in a cabinet or gym bag. If you want the biggest protein hit from a single scoop and you like a bold, candy-like fruit flavor, this is your pick. skip it if you prefer a subtler, less sweet drink that mixes with less fuss.
Why it wins
- Highest protein per scoop on this list at 25g
- Fully transparent label — no proprietary blends
- Gluten and soy free, zero fat and zero sugar
Watch out for
- Flavor is very sweet — needs heavy dilution with water
- Some foaming and mild clumping after shaking
- Premium price point compared to 20g-per-serving options
Go-to pick if: you want the biggest protein hit from a single scoop and you like a bold, candy-like fruit flavor.
pass on it if: you prefer a subtler, less sweet drink that mixes with less fuss.
2. JYM Supplement Science Iso JYM Grape
A PhD-designed clear protein with only six ingredients — one of the shortest labels in the category.
JYM Iso JYM uses an “ultra-cold filtration process” that the brand claims keeps the native protein ratios intact while producing a drink that turns completely clear — no milky haze. Each scoop delivers 20g of whey protein isolate and just 90 calories, with zero fat and zero sugar. The Grape flavor gets consistent praise; one reviewer says it “feels like I’m drinking a non-carbonated grape soda,” and another calls it “Jolly Rancher grape.” That is a more candy-like flavor than the Ascent Clear Whey’s Piña Colada profile, which is more tropical.
There is a trade-off on mixing. Some users note it can clump — one review deducted a star because the scoop is large and the powder takes effort to blend smoothly. The official recommendation is to use a shaker bottle, and several reviewers found that using hot water helps it dissolve more completely. It comes in a 20-serving tub, which is fewer servings than the Rule 1 Clear Whey (27 servings) in a similar size tub. At 1.5 pounds, the container weight is in the middle of the pack — lighter than the GHOST (1.57 pounds) but heavier than the Ascent (1.14 pounds). Grab this if you prioritize a short, clean ingredient list and enjoy a punchy, sweet grape flavor that mimics a soda. Consider another if you want a simple to use mix that dissolves instantly with no lumps.
Where it shines
- Only 6 ingredients — extremely clean formulation
- Ultra-cold filtration creates a fully clear drink
- Candy-like grape flavor is a fan favorite
Where it stumbles
- Can clump during mixing; requires some technique
- Only 20 servings per container
- Sweet flavor may be too intense for some palates
Best suited for: anyone who prioritizes a short, clean ingredient list and enjoys a punchy, sweet grape flavor that mimics a soda.
Consider another if: you want a simple to use mix that dissolves instantly with no lumps.
3. Oath Nutrition Clear Whey Isolate Protein Powder, Kiwi Strawberry
Grass-fed whey isolate gives you 20g of protein with no added sugar — and 21 servings per bag.
Oath Nutrition sources its whey from grass-fed cows, which separates it from conventional isolates that may come from grain-fed herds. Each serving delivers 20g of complete protein with no added sugar, and the 21-serving count per bag is slightly higher than the 20-serving standard you see on the GHOST and JYM options. The Kiwi Strawberry flavor has earned a high 4.5-star rating from 465 reviews, with buyers calling it “the best-tasting clear protein powder” they have tried. One review noted it mixes easily with creatine and collagen straight in a water bottle, which is a practical plus for stackers.
The bag format is a departure from the traditional tubs — it is 9.65 x 8.19 x 2.87 inches and weighs 1.32 pounds, making it slim and easy to toss into a work bag. The catch is that it can be finicky to dissolve. One reviewer advises mixing it with lukewarm water first, then adding ice afterward, to avoid clumping. Another mentions it is “tough to dissolve” in cold water without that warm-water step. This is a small extra step, but worth knowing if you are accustomed to just shaking cold water and downing it. A good choice if you value grass-fed sourcing and want to mix your protein with other supplements like creatine in one bottle. Look elsewhere if you want a no-fuss shake that dissolves perfectly in cold tap water.
Why we like it
- Grass-fed whey isolate — a quality differentiator
- 21 servings per bag, no added sugar
- High customer satisfaction (4.5 stars from 465 ratings)
Why we hesitate
- Requires lukewarm water then ice for best dissolve
- Bag packaging is less sturdy than a tub
Ideal for: someone who values grass-fed sourcing and wants to mix their protein with other supplements like creatine in one bottle.
Look elsewhere if: you want a no-fuss shake that dissolves perfectly in cold tap water.
4. Rule 1 Proteins Clear Whey Isolate, Strawberry Lemonade
27 servings of 20g whey isolate — 7 more servings than most competitors per container.
That means the Rule 1 tub lasts significantly longer than the 20-serving standard of GHOST and JYM. Each serving provides 20g of all-whey isolate with 90 calories, zero sugar, and over 9g of naturally occurring EAAs (essential amino acids). It is manufactured in a GMP-certified U.S. facility and every batch is banned-substance tested by Informed Choice and Informed Protein — the highest third-party certification for athletes and serious lifters. Unlike the Myprotein option (3.9 stars), buyer ratings here are solid with no bitter aftertaste complaints dominating.
The Strawberry Lemonade flavor lands well with buyers. One reviewer says it has “no weird aftertaste,” which is a common complaint with clear proteins. The mixing trick that works for most is adding water first to the shaker before the powder to minimize foam, then letting it sit for a minute to fully dissolve. At 1.52 pounds, the round tub (5.5 x 5.5 x 8.75 inches) is compact and stacks neatly, though it is note the single negative review complains about the sweetness: “sweet asf takes 3 business days dilute it well,” suggesting it may be too intense for some palates. A smart pick if anyone who wants a clean, third-party tested protein and a tub that lasts well past a month. Pass on it if you prefer a very mild sweetness or are not willing to dial in the water ratio.
What we love
- 27 servings — most generous count on this list
- Third-party tested by Informed Choice and Informed Protein
- No weird aftertaste reported by most reviewers
What gives us pause
- Sweet flavor may require heavy dilution
- Foaming can be an issue if mixing technique is off
Smart pick for: anyone who wants a clean, third-party tested protein and needs a tub that lasts well past a month.
Pass on it if: you prefer a very mild sweetness or are not willing to dial in the water ratio.
5. Isopure Clear Whey Isolate Protein Powder, Citrus Lemonade
A simple 5-ingredient clear whey that has been a staple for years — over 34,000 ratings.
Isopure Clear Whey is the veteran of this category. It has been on the market since July 2018 and has accumulated nearly 35,000 ratings, giving it a level of long-term feedback that no other product here can match. The formula keeps things minimal: just five ingredients, no artificial sweeteners, and a low-carb profile that fits macro-focused lifestyles. Each serving delivers 20g of ultra-filtered whey protein isolate. The Citrus Lemonade flavor is crisp, and owners mention a “smooth, water-like texture, no slime” — exactly what you want from a clear protein. It has fewer ingredients than the JYM (6), so if label simplicity is your top priority, this edges ahead.
The biggest trade-off is the serving count. At just 16 servings per container, it provides 4 fewer servings than the 20-serving standard set by products like GHOST and Myprotein — a 25% less gap in servings. The tub dimensions are also the largest on this list at 11.61 x 6.3 x 10.63 inches, roughly double the footprint of the GHOST tub, so it takes up more pantry space. On the plus side, some creative reviewers blend it with other drink packets (like Dunkin SF pineapple mango) to adjust the flavor, which shows it works as a neutral base for custom recipes. Best for the buyer who wants an established brand with a very clean, minimal ingredient list and does not need a huge number of servings. Not for you if you want a high serving count or a compact tub that fits in a small cabinet.
What stands out
- Only 5 ingredients — no artificial sweeteners
- Nearly 35,000 ratings for reliable long-term feedback
- Smooth, water-like texture, not slimy
What holds it back
- Only 16 servings per tub — less value for the volume
- Bulky container is harder to store
Best for: the buyer who wants an established brand with a very clean, minimal ingredient list and does not need a huge number of servings.
Not for you if: you want a high serving count or a compact tub that fits in a small cabinet.
6. Ascent 100% Clear Whey Protein Powder, Pineapple Coconut
A no-artificial-anything clear whey that is lighter on the calories but heavier on the foam.
Ascent’s Clear Whey stands out for its clean-label commitment: zero artificial flavors and zero artificial sweeteners. Each serving delivers 20g of protein with 2.1g of leucine (the amino acid that triggers muscle protein synthesis), and the calorie count sits at 100 per scoop — 25% more than Myprotein Clear Whey’s 80-calorie serving but still low enough for most diet phases. The Pineapple Coconut flavor is described by buyers as tasting “like piña colada,” and it is versatile enough to blend with frozen pineapple for a post-workout smoothie.
The big caveat here is mixing difficulty. One verified buyer bluntly reports “high foaming and clumping issues initially,” and the fix takes patience: pour over ice, let it sit for 10 minutes, and the foam and clumps gradually dissolve. Another reviewer notes you need “double water” to get the right texture. The tub is also the lightest on the list at 1.14 pounds — a full 38% less weight than the GHOST tub (1.57 pounds) — and the compact package dimensions (9.61 x 7.95 x 3.74 inches) make it the most travel-friendly. One critical review mentions a chemical taste and even acne breakouts, which is a reminder that any whey can affect skin sensitivity. Reach for this if you need the absolute cleanest ingredient deck and are willing to wait 10 minutes for the foam to settle. it’s not for you if you want a protein that mixes quickly and drinks immediately without preparation steps.
Why it ranks
- Zero artificial flavors or sweeteners — truly clean
- Informed Sport certified for athletes in testing pools
- 2.1g leucine per serving supports muscle synthesis
What to watch
- Significant foaming and clumping — requires patience
- Some reviewers report a chemical aftertaste
Reach for this if: you need the absolute cleanest ingredient deck and are willing to wait 10 minutes for the foam to settle.
look elsewhere if: you want a protein that mixes quickly and drinks immediately without preparation steps.
7. Myprotein Clear Whey Isolate Protein Powder, Peach Mango
The lowest-calorie clear protein on this list — 80 calories — with a bold Peach Mango flavor.
Myprotein Clear Whey Isolate uses hydrolyzed whey protein, a form that is pre-digested to some extent for faster absorption. Each serving delivers 20g of protein for just 80 calories with zero fat and zero sugar, making it the clear calorie leader on this list — it is 25% lower in calories than the Ascent Clear Whey (100 calories). The Peach Mango flavor gets mixed feedback: some users love it (“tastes like sugar-free Body Armor”), while others find it “extremely sweet, tastes like sugar syrup with bitter aftertaste.” The powder mixes best when you shake it for 10-15 seconds and let it rest in the fridge for a few minutes to settle the foam.
The value proposition is strong. At 20 servings per container, you get the same count as the GHOST and JYM options at a lower entry point. However, the customer rating is lower at 3.9 stars out of 605 reviews — the lowest satisfaction on the list, driven by polarizing sweetness and a reported aftertaste. The container size (8.54 x 5.04 x 4.92 inches at 1.3 pounds) is mid-range, but one buyer grumbles that the tub is “obnoxiously large” for the amount of powder inside, calling out wasteful packaging. A fun twist: the Peach Mango flavor can be used in smoothies or even frozen into protein pops. Consider this if your priority is the lowest possible calorie count and you enjoy very sweet, fruity flavors. Look away if you are sensitive to strong sweeteners or bitter finishes in your protein drinks.
Where it saves
- Lowest calories per serving at 80
- Hydrolyzed whey for faster uptake
- 20 servings give decent bang for the price
Where it slips
- High sweetness and a bitter aftertaste are common complaints
- Customer satisfaction is the lowest on the list at 3.9 stars
- Packaging is oversized for the amount of product
Consider this if: your priority is the lowest possible calorie count and you enjoy very sweet, fruity flavors.
Look away if: you are sensitive to strong sweeteners or bitter finishes in your protein drinks.
Understanding the Specs
Whey Protein Isolate vs. Hydrolyzed Whey
Whey protein isolate is the purest form of whey — it goes through extra processing to strip away most of the fat and lactose, leaving behind a high-protein, low-calorie powder that mixes clear with water. Hydrolyzed whey takes that a step further by breaking the protein chains into smaller pieces, which some people absorb faster. Both types give you that clear, juice-like drink instead of a milky shake. Just know that a “clear” protein nearly always uses isolate or hydrolyzed isolate to achieve transparency.
The 20g vs. 25g Protein Decision
Most clear proteins standardize at 20g per serving, which is plenty for most people after a workout or between meals. A handful of brands push to 25g per scoop, like the GHOST Clear Whey. The difference matters if you track your protein intake closely or if you want fewer scoops per day to hit a high target. The trade-off is that extra protein often comes with a more intense flavor and sometimes a higher price per serving. Match the protein number to your daily goal, not the biggest tub.
