Clear protein (also called protein juice, whey juice, or a protein refresher) is whey isolate dissolved in water so it drinks like a light, fruity juice instead of a thick milkshake. It is ideal if you find creamy shakes heavy, you train in hot weather, or you just want 20+ grams of protein that tastes refreshing. In Canada, our owner-tested top picks are ALT Clear Protein (grass-fed whey isolate), the Believe Protein Refresher juice-style isolate, ready-to-drink Applied Nutrition Sparkling Protein Collagen Water, the Believe Clear Collagen Refresher, and single-serve Prozis Clear Whey Isolate sachets to sample first.

How to choose

Want the most muscle-building protein per serving? Go with a clear whey isolate — ALT, Believe Protein Refresher, or Prozis — all deliver roughly 20+ grams of complete whey protein per scoop with very little fat or sugar.

Want skin, hair, nail and joint support instead of muscle protein? Choose a collagen option. The Believe Clear Collagen Refresher (powder) and the Applied Nutrition Sparkling Protein Water (canned) both supply 10g of collagen peptides; note collagen is not a complete muscle-building protein, so pair it with whey if your goal is training recovery.

Want zero prep? The Applied Nutrition sparkling can is ready to drink — grab it from the fridge, no shaker needed.

New to clear protein? Start with a single Prozis sachet to find a flavour you love before committing to a full tub. If you are sensitive to dairy, ALT is 99.9% lactose-free and the collagen options are dairy-free.

FAQ

What is clear protein or protein juice? It is whey protein isolate (or collagen) formulated to dissolve clear in water, so it tastes and drinks like a light fruit juice rather than a creamy milkshake, while still delivering high protein.

How much protein is in clear whey isolate? Most clear whey isolates, including ALT, Believe and Prozis, provide about 20-22 grams of protein per serving with minimal fat and sugar.

Is clear protein the same as collagen water? No. Clear whey is a complete muscle-building protein, while collagen drinks such as Applied Nutrition Sparkling Protein Water and the Believe Collagen Refresher focus on skin, hair, nail and joint support and are not complete proteins.

Does clear protein taste better than regular whey? Many people who dislike thick shakes prefer it because it is light, fruity and refreshing, especially post-workout or in hot weather. Taste is personal, so trying a single Prozis sachet first is a low-cost way to decide.

Can I drink clear protein every day? Yes, clear whey isolate fits easily into a daily routine as a high-protein, low-calorie drink. Use it to help meet your protein target alongside whole foods.

Are these products sugar-free? The clear whey options have no added sugar and are sweetened with monk fruit or stevia, and the collagen sparkling water is zero sugar. Always check the label for exact carbohydrate content.
