6 Best Clear Protein Powder | Refreshing, Not Thick

A grass-fed isolate that tastes like pink lemonade and mixes without clumps — at a price that beats the GHOST.

Each scoop of Oath delivers 20g of complete grass-fed protein with no added sugar, and the whole bag contains 18 servings. Reviewers consistently note that it “mixes great with zero chunks” and has a tart, refreshing flavor. One reviewer noted they “mixed with 8oz water, refrigerated, then diluted” to get a strong balance. The 100-calorie count per serving keeps it lean. That is 10 calories more per serving than the Myprotein (90 calories), but the grass-fed sourcing appeals to buyers who care about where their dairy comes from.

The package dimensions (10.35 x 3.27 x 2.64 inches) are notably smaller than the GHOST tub, so it stores easily in a gym bag. A few owners mention a very slight chalky taste if you use less water, but overall it blends cleanly with a frother or shaker. At 11.85 ounces total, it is lighter than the GHOST (1.57 Pounds) while still offering solid protein content.

This is your pick if you prioritize a bang-for-buck tub with grass-fed sourcing and a reliable pink lemonade flavor that customers describe as “light, refreshing.” If you need the highest protein per scoop, the GHOST leads on that spec.

A budget-friendly hydrolyzed whey that offers 20g protein and a juice-like texture — if you can get it mixed right.

Myprotein’s clear isolate uses hydrolyzed whey protein, which is pre-digested into smaller protein fragments to help it dissolve in cold water. Each serving contains 20g of protein with only 90 calories, zero fat, and zero sugar. The tub holds 20 servings and measures 4.72 x 4.72 x 7.87 inches — a more compact shape than the GHOST tub (5.75 x 8.25 x 4.75 inches).

Buyers are split on the mixing experience. While some say it “mixes easily in cold water to a light, juice-like drink,” others report “powder does not dissolve fully, leaving clumps despite shaking/stirring.” The fine powder requires a shaker bottle and patience — reviewers recommend letting it sit 10-20 minutes after shaking, then shaking again. Compared to the GHOST (1.57 Pounds), it is lighter at 1.39 Pounds, making it easier for travel.

If budget is your primary concern and you are comfortable with a slightly finicky mixing process, this Myprotein option delivers solid macros at a low price. If you want a guaranteed smooth dissolve right out of the shaker, skip it.

A PhD-designed clear whey that tastes exactly like a grape Jolly Rancher candy — but you need a blender.

Iso JYM uses an ultra-cold filtration process (a method that uses cold temperatures to separate the protein, preserving its quality) to create a clear mix with only 6 ingredients. Each 90-calorie scoop provides 20g of whey protein isolate, zero fat, and zero sugar. The tub contains 20 servings and measures 5.6 x 5.6 x 7.8 inches, weighing 1.5 Pounds — comparable in size to the GHOST tub. One buyer describes it as a “great light, refreshing protein drink,” while others call it a “non-carbonated grape soda.”

The catch is that many reviewers point out the powder “clumps badly” unless you use an immersion blender. A fix some reviewers use is mixing with hot water in a blender bottle first — one described it as “like warm jello before it sets.” Another trick is “adding a little unsweetened grape Kool aid” to tame the sweetness. Compared to Oath Nutrition’s 18 servings, the JYM tub offers 20 servings — 11% more per container.

If grape candy is your favorite flavor profile and you have an immersion blender handy, this JYM isolate delivers on taste. If you want a quick shake-and-drink experience without equipment, skip it.

A lab-tested clear isolate with the most servings per tub — 27 — at a competitive price.

Rule 1’s clear isolate offers 27 servings per tub. That is 7 more servings than the GHOST and 9 more than Oath Nutrition, giving you the best stretch per container. Each scoop provides 20g of all-whey isolate, 90 calories, zero sugar, and zero fat. The tub measures 5.5 x 5.5 x 8.75 inches and weighs 1.52 Pounds, close to the JYM tub dimensions.

This is the only clear protein in this list that is third-party tested by both Informed Choice and Informed Protein. Informed Choice is a certification that means each batch is tested for banned substances; Informed Protein verifies the protein content is accurate. So you know what is actually in the tub. Buyers rate it highly at 4.5 out of 5 stars. Some note that mixing 1 scoop per 12 ounces of water can be “too sweet,” and recommend over-diluting or letting it sit in the fridge for a few minutes after mixing to fully dissolve. The Strawberry Lemonade flavor gets consistent praise for having “no weird aftertaste.”

If you want the most protein servings per purchase and third-party quality verification matters to you, Rule 1 is a strong mid-range choice. If you are looking for a smaller tub to try before committing to 27 servings, skip this one.

An allergen-free clear protein with 22g per scoop and 4.5g of BCAAs, all from a nut-free and soy-free facility.

SEEQ offers 22g of clear whey isolate per scoop with 4.5g of BCAAs (branched-chain amino acids, which are specific protein building blocks that help with muscle recovery). The container holds 22 servings. It is manufactured in a nut-free and soy-free facility, making it the best option if you have common food allergies. The package weighs 1.35 Pounds and measures 8.78 x 5.94 x 5.87 inches — a wider profile than the Myprotein tub but comparable in height.

Shoppers say the Watermelon Wave flavor is “refreshing” and “mixes well with no grit or aftertaste.” One reviewer warns that adding ice after mixing causes clumping, so the best method is to mix with room-temperature water first, then add ice. A critical note from the reviews: people prone to heartburn or GERD (gastroesophageal reflux disease, a condition where stomach acid flows back into the throat) should avoid this product due to high malic acid content — its pH is similar to lemon juice. It also contains Stevia, a natural sweetener that may cause gastric distress for some people.

If you need a nut-free, soy-free clear protein with a solid 22g protein count and a summer-fresh watermelon flavor, SEEQ delivers. If you have acid reflux sensitivity or want the highest protein grams per scoop, skip it.
