If you are tired of thick, milky shakes that feel like a dessert, clear whey protein isolate turns your protein into a refreshing juice-like drink that mixes with water and tastes like lemonade, watermelon, or blue raspberry. The catch is that brands vary wildly in protein per scoop, serving count, and how close they come to an actual clear drink instead of a cloudy one. This guide walks you through six of the best options so you can pick the one that actually fits your goals and your taste.
I’m Mohammad Maruf — the founder and writer behind WellFizz. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Whether you are new to this category or swapping from a traditional shake, these are the highest-rated containers of clear whey protein isolate right now, ranked by protein density, serving value, and real buyer feedback.

How To Choose The Best Clear Whey Protein Isolate
Clear whey isolate mixes with cold water into a translucent, fruit-forward drink instead of a thick shake. Because the experience differs from traditional whey, focus on a few key numbers that matter more here.
Protein Per Serving and Serving Count
The two numbers that reveal real value are grams of protein per scoop and total servings per container. A tub with 25g per serving gives you more building blocks per drink than one with 20g, and a bag with 21 servings lasts longer than one with 10. Multiply them to see which tub delivers more total protein.
Calories and Clean Ingredients
Most clear whey isolates hover around 80 to 100 calories per serving, with zero fat and zero added sugar. If you track macros, the lower-calorie option leaves more room in your daily budget. Check for artificial sweeteners and flavors if you prefer a cleaner label.
Mixing, Clarity, and Foam
Because clear whey dissolves in water, mixability without clumps and foam settling speed matter more than with milky shakes. Real buyers report some brands leave persistent foam or a cloudy appearance even after shaking. Look for products where reviewers consistently mention easy mixing and a genuinely clear drink.

In‑Depth Reviews
1. GHOST Clear Whey Isolate Protein Powder, Blue Raspberry
The tub that delivers 25g of protein per scoop versus 20g for most competitors.
If your top priority is maximizing protein per drink, GHOST Clear Whey leads the category by packing 25g of pure whey protein isolate into every serving, compared to the 20g you get from the Ascent and Bloom options. That extra 5g matters when you are counting scoops to hit daily protein targets. The Blue Raspberry flavor is designed to taste like a light, fruity sports drink rather than a heavy shake, and owners mention it mixes well with minimal clumping after the foam settles — one reviewer called it a “liquid Jolly Rancher.”
The tub is sugar free, soy free, and zero fat, and GHOST uses a fully transparent label with no proprietary blends, so you see every ingredient. Some buyers do note that the flavor can be very sweet — one reviewer found the strawberry watermelon variant “insanely sweet” and needed to dilute it with 20 to 24 ounces of water instead of the standard amount. A few also mention the price feels high, though a subscription helps bring it down.
Protein punch
- 25g of whey protein isolate per serving — the highest in this lineup
- Zero fat and zero sugar for clean macro tracking
- Buyers rave about the “liquid Jolly Rancher” taste that masks protein aftertaste
Sweetness caveats
- Very sweet — some users need to double the water to balance flavor
- Price is the highest in the category at the premium tier
- Foam can form when rinsing the shaker bottle
Reach for this if: you want the most protein per scoop and can handle intense fruit sweetness — this tub outguns every other clear whey on protein density.
Look elsewhere if: you prefer a milder, more diluted flavor or need a lower price per serving.
2. Oath Nutrition Clear Whey Isolate Protein Powder, Kiwi Strawberry
The bag that gives you the most servings — 21 for Oath versus 10 for Bloom.
Oath Nutrition stands out with 21 servings per bag at 1.32 pounds, which is the highest serving count in this list, versus the Universal Nutrition clear whey at 1.1 pounds. That means fewer repurchases and more shelf life for your routine. Each scoop delivers 20g of complete, grass-fed protein with no added sugar, making it a solid everyday option whether you are sipping post-workout or mixing into a protein sorbet.
The Kiwi Strawberry flavor is positioned as a light, fruity drink that works for summer workouts or poolside sipping, and Oath encourages creative use — the brand suggests mixing it into sorbet, ice cream, or even protein cheesecake. Because this is a newer product with no buyer reviews yet in the data, the long-term mixing and taste experience is still unconfirmed by the community, so treat this as a promising, well-priced bet rather than a proven crowd-pleaser.
Bag longevity: 21 servings at 20g each means you get 420g of protein per bag, versus Bloom’s 10 servings.
One unknown: No customer reviews available yet, so the real-world foam, clarity, and flavor profile remain untested by the community.
Who it fits: shoppers who value bulk servings and grass-fed sourcing over brand reputation — the math works in your favor if you go through protein fast.
Who should pause: anyone who wants proven taste feedback before buying — wait for reviews to populate.
3. Clear Whey Isolate Protein Powder, Watermelon Limeade (Universal Nutrition)
The clear whey that buyers describe as “delicious and refreshing” with no clumps and minimal foam.
Universal Nutrition has been pushing sports nutrition forward since 1983, and their clear whey isolate earns consistent praise from real buyers. One reviewer called the Watermelon Limeade flavor “delicious and refreshing” and noted it mixes without clumps or foam, with only 100 calories and 1g of carbs per serving. Another buyer said it “mixes completely” with a “good tangy taste” and no bloating — a common complaint with traditional milky whey. The formula includes 5g of BCAAs per scoop for muscle recovery, and it is produced in a GMP-certified US plant with lab testing.
Unlike some clear wheys that require heavy shaking or prolonged settling, customers note this one dissolves easily even with room-temperature water. A couple of reviewers mention the flavor can be slightly salty, like a hydration drink, and that the 10-ounce water recommendation is important — 15 ounces dilutes the taste noticeably. At 1.1 pounds and 20 servings, it lands in the mid-weight range for the category.
Buyer-approved mixing
- Buyers consistently say it mixes without clumps or foam — a rare unanimous review pattern
- 5g BCAAs per serving support post-workout recovery
- Trusted brand with 40+ years in sports nutrition and GMP-certified manufacturing
Portion precision
- Flavor gets thin if you exceed 10 ounces of water — stick to the ratio
- Some buyers find the taste slightly salty, similar to an electrolyte drink
- Only 20 servings per bag, so it runs out faster than the 21-serving Oath bag
Grab this one if: you want a proven, no-fuss clear whey with a flavor that actual buyers love and no mixing drama.
skip it if: you want the highest protein per serving (GHOST has 25g) or prefer a sweeter, candy-like profile.
4. Ascent 100% Clear Whey Protein Powder, Pineapple Coconut
The clear whey that a top nutrition magazine picked as its best clear protein in April 2026.
Ascent Clear Whey is built around clean ingredients — zero artificial flavors, zero artificial sweeteners, certified gluten-free, and Informed Sport certified, which matters if you compete or want third-party testing assurance. Each serving delivers 20g of protein with 2.1g of leucine to help trigger muscle protein synthesis, all for 100 calories. The Pineapple Coconut flavor gives a tropical twist that buyers describe as “refreshing” with “no weird aftertaste.” One reviewer noted it was named a Top Healthline pick in April 2026, adding an independent endorsement to its resume.
The trade-off is that foam is a recurring theme in reviews. Several buyers mention the drink produces noticeable foam that requires time to settle — one recommended an electric milk frother to avoid clumps, while another said refrigerating for a few hours helps the foam dissipate.
Ingredient integrity: zero artificial anything and Informed Sport certification set this apart if you avoid processed additives — a clear advantage over brands that use artificial sweeteners.
Foam factor: buyers consistently report foam that needs time to settle, so plan your shake-making a few minutes before you want to drink.
Right for you if: you prioritize a totally clean ingredient list and want a brand backed by a Healthline recommendation — the Pineapple Coconut flavor is a genuine crowd-pleaser.
Not your best bet if: foam bothers you or you want a protein that mixes crisp with zero wait time.
5. Myprotein Clear Whey Isolate Protein Powder, Peach Mango
At 80 calories per serving, this is the lowest-calorie clear whey — 80 calories versus 100 for Ascent.
Myprotein’s Clear Whey Isolate is made from hydrolyzed whey protein (a type pre-digested for faster absorption) and delivers 20g of protein with zero fat and zero sugar in just 80 calories. That calorie count is a meaningful edge if you are cutting or keeping a tight daily budget — the Ascent option has 100 calories per serving. The Peach Mango flavor is designed to taste like juice rather than a milky shake, and the brand recommends mixing one scoop with 10 to 12 ounces of cold water and letting the natural foam settle.
Myprotein offers a wide variety of fruit flavors including Lemonade, Strawberry, and Tropical Dragonfruit, so you have options if you cycle through flavors quickly. The bag has been on the market since January 2021, giving it a longer track record than newer entrants. There are no customer reviews in the provided data, so real-world feedback on mixing and taste is not available to confirm the experience — factor that in if you prefer buyer-verified picks.
Macro-friendly design: the 80-calorie, zero-fat, zero-sugar profile gives you the leanest option for calorie-conscious plans.
No buyer input available: without customer reviews, the real-world mixing experience and flavor accuracy are unconfirmed by the community.
Reach for it if: every calorie counts and you want the lowest-energy clear whey that still delivers 20g of protein — the hydrolyzed formula helps with rapid absorption.
Hesitate if: you rely on buyer reviews to validate taste and mixability before committing to a bag.
6. Bloom Clear Protein, Whey Protein Isolate with Collagen Peptides, Strawberry Watermelon
The only clear whey that combines 15g whey isolate with 5g collagen peptides for hair, skin, and nail support.
Bloom’s clear protein stands apart by adding 5g of collagen peptides and digestive enzymes to 15g of whey protein isolate, totaling 20g of protein in just 90 calories. That collagen addition is unique in this category — no other pick here offers it — and the digestive enzymes are designed to make the drink easier on your stomach. Buyers describe the Strawberry Watermelon flavor as tasting like a melted Jolly Rancher, with one reviewer noting it is “light, refreshing, mixes easily without grit.” The bag is also female-founded by co-founder Mari Llewellyn, who created Bloom to address the gap in quality-tasting supplements.
The biggest catch is serving count and value. The bag contains only 10 servings, and one buyer explicitly said: “Expensive at for 10 servings.” The Oath bag has 21 servings at a similar overall price tier. Some reviewers also report the drink is not completely clear — one called it “cloudy, not clear” — and that foam can persist for five or more minutes after shaking. If you want the collagen-and-isolate combo, this is your only option, but the per-drink cost is steep.
Unique formula blend
- Only clear whey with added collagen peptides (5g) and digestive enzymes
- Buyers praise the Jolly Rancher-like flavor and no-grit texture
- 90 calories and no added sugar fits clean eating plans
Value concerns
- Only 10 servings per bag — the smallest serving count in the lineup
- Buyers flag the price as expensive for the serving count
- Some reviewers report cloudiness and persistent foam that takes 5+ minutes to settle
Choose this if: you specifically want collagen alongside your protein and digestive enzymes are a priority — no other clear whey offers this exact mix.
Pass on it if: serving count and per-drink cost matter more than added ingredients — the Oath option has 21 servings and the Universal option has 20 servings, versus 10 servings here, at a similar total cost.
Understanding the Specs
Protein Per Serving
This is the number that tells you how much muscle-building material you get in each drink. Most clear whey isolates range from 20g to 25g per scoop. GHOST leads the category with 25g, while most others sit at 20g. If you are counting total daily protein, a 25g serving reduces the number of scoops you need compared to a 20g option.
Calories Per Serving
Clear whey isolate is naturally low in calories because it strips out fat and sugar. You will see numbers from 80 to 100 calories per scoop. The Myprotein option hits 80 calories, while the Ascent has 100 calories. For tracking macros, the lower number leaves more room for other foods in your daily budget.
Servings Per Container
This tells you how many drinks you get from one bag before you need to repurchase. The Oath bag delivers 21 servings, while the Bloom bag gives 10. Always check serving count alongside price to understand real value.
Mixing and Clarity
Clear whey is supposed to dissolve in water and stay translucent, but not all do well. Some brands produce persistent foam that takes minutes to settle, and others turn cloudy instead of clear. Look for buyer reviews that specifically mention “no clumps,” “clears quickly,” and “no grit” — these are the signals of good formulation.
