Clear protein water is the newest sub-category of RTD protein. Where a traditional shake uses milk or plant-cream as the base, clear protein water is a juice-light, almost iced-tea-textured drink with 15 to 20 g of hydrolysed whey protein isolate dissolved into a fruit-flavoured water. It is designed for people who want the protein hit without the dairy weight, especially in summer and post-cardio.
The category is small but expanding fast. Quest Clear Protein, BODYARMOR Premium Clear, Isopure Infusions, and Bare Performance Nutrition Clear Whey are the names worth watching. Pricing currently runs $2.80 to $4.20 per 16 fl oz bottle, with multi-pack discounts narrowing the gap to roughly $2.50 to $3.50 per serving. Flavour profiles skew fruit-forward (peach, raspberry, citrus) rather than chocolate or vanilla.
What to look for: hydrolysed whey isolate (not concentrate; concentrate goes cloudy in water), 15 g protein minimum, under 2 g sugar, and a clean ingredient panel. The reason these drinks stay clear is that the protein is hydrolysed into smaller peptides; this also makes them faster to absorb, which is useful around training. Our Value Score will rank every clear protein water by grams of protein per dollar as our data set fills out in Phase 2.
We are tracking but not yet ranking the following. Cross-links go to the parent category until product pages are live.
It is a ready-to-drink beverage that suspends 15 to 20 g of hydrolysed whey isolate in flavoured water. The result is a thin, juice-like drink rather than a creamy shake. Some brands add electrolytes; most do not.
Per gram of protein, yes. Hydrolysed whey is highly bioavailable and triggers muscle protein synthesis as effectively as concentrate or isolate at the same dose. The catch is that bottles top out at 15 to 20 g, so you may need two to match a 30g+ premium RTD.
Standard whey isolate scatters light, which makes the liquid look milky. Hydrolysed whey breaks the proteins into smaller peptides that dissolve cleanly in water. The trade-off is a slightly bitter, lower-foam mouthfeel that brands mask with fruit flavours.
Mostly yes. Whey isolate already contains under 1% lactose; hydrolysed whey is similar. People with severe lactose intolerance still react in some cases, so try a single bottle first. Anyone with a true whey allergy should avoid the category entirely.
Yes; the hydrolysed whey absorbs in 15 to 30 minutes, so taking it 30 minutes pre-workout works. The light texture is one of the main reasons people pick it over a milkshake before training.
Yes, on a per-gram basis. Clear protein water is currently 30 to 70% more expensive per gram of protein than Premier Protein or Fairlife. The premium covers hydrolysed whey, lower-volume production, and the novelty of the format.
Phase 2 of our data drop covers Quest Clear, BODYARMOR Premium Clear, and Isopure Infusions. See how we track prices for an overview of our scraping cadence and source retailers.
