Protein Water Buying Guide

Shop protein water from PharmaLabs, Applied Nutrition, ATP Science, Nexus Sports Nutrition and Rule 1 Proteins.

Last Updated: Monday 19th October 2026

What Is Protein Water?

Protein water is a protein powder that mixes with cold water into a light, clear, juice-like drink instead of a thick, milky shake. It's made with water-soluble proteins such as whey protein isolate, collagen, beef protein isolate or pea protein, and usually comes in fruity flavours. You'll also see it called clear protein or clear whey.

At Nutrition Warehouse, we stock protein water powders and ready-to-drink options from PharmaLabs, Applied Nutrition, ATP Science, Nexus Sports Nutrition, Rule 1 Proteins and more. It's part of our full protein powder range.

Protein Water vs Protein Shake

Both help you add protein to your day. The difference is the type of protein and how it drinks:

Protein water Protein shake
Texture Light and clear, like a juice or cordial Thick and creamy
Mixed with Cold water Water or milk
Common flavours Fruity, sour, soft drink-style Chocolate, vanilla, dessert-style
Protein sources WPI, collagen, beef isolate, pea protein Whey, casein, plant blends

Types of Protein Water

Protein water is made from a few different protein sources. Here's how they compare:

Type What it's made from Dairy free? Example
Clear whey Whey protein isolate (WPI) No R1 Clear Whey Isolate by Rule 1 Proteins
Collagen protein water Hydrolysed collagen peptides Usually, check the label NoWay Collagen Protein Water by ATP Science
WPI and collagen blends Whey protein isolate plus collagen No Protein Water by PharmaLabs
Beef protein isolate Hydrolysed beef protein isolate Yes ISO Clear by Applied Nutrition
Vegan protein water Pea protein isolate Yes Clear Protein by Optimum Nutrition

Formulas vary by product, so always check the label for the protein source and amount per serve.

Shop Protein Water by Format

  • Protein water powder: the most popular format and usually the lowest cost per serve. Mix a scoop with cold water in a shaker.
  • Ready-to-drink protein water: cans and bottles with no mixing needed, found in our protein drinks range below.
  • Unflavoured protein water: Super Protein by Nexus Sports Nutrition comes in a Super Tasteless flavour you can add to other drinks, and Faction Labs and Primabolics also offer unflavoured options.
  • Bulk sizes: 1kg and larger tubs usually work out cheaper per serve if you drink protein water every day.

How to Choose the Right Protein Water

  1. Protein source: clear whey for a whey-based option, collagen or beef isolate if you'd prefer to avoid dairy, or pea protein for a vegan option.
  2. Protein per serve: most protein waters in our range provide around 20–27g of protein per serve.
  3. Dietary needs: check the label if you need dairy-free, lactose-free or vegan.
  4. Flavour: pick a fruity, sour or soft drink-style flavour you'll enjoy, or unflavoured to mix into other drinks.
  5. Size and cost per serve: compare the number of serves per pack, as tub sizes range from 10 to 30+ serves.

How to Use Protein Water

Always follow the serving size and directions on your product label. Most protein water powders are mixed with cold water in a shaker. Some clear proteins foam when shaken, so let the drink settle for a minute before drinking. Protein water can be enjoyed after training or between meals. It is not a sole source of nutrition and should be used alongside a balanced diet.
