Clear whey: what it is, who it's for, and which one to choose

No milk, no thick shake: clear whey looks like a fruit juice or an iced tea, with as much protein as a whey. Here is how it's made, how to mix it, and our 6 clear whey proteins compared.

500 mlof cold water per serving: a proper big glass

The essentials in 30 seconds

  • What it is: a whey isolate made clear, which mixes with water like a cordial. Fruity or iced tea flavours.
  • The numbers: 21 to 27 g of protein for about 90 to 110 kcal per serving, with almost no sugar or fat.
  • How to mix: 500 ml of very cold water, shaker, then 1 to 2 minutes' rest so the foam settles.
  • Who it's for: anyone who dislikes milky shakes, after a sweaty session, or for variety. It isn't vegan: it comes from milk.

What exactly is clear whey?

It is whey isolate, the most filtered whey protein, processed to stay clear in a slightly acidic liquid. The manufacturer adds an acidifier (often citric acid), fruity flavourings and sweeteners. The result: a clear, light and refreshing drink, far from a creamy chocolate shake.

When the label states it, whey protein isolate makes up about 94% of the powder: it is what provides the protein. To understand the different types of whey (concentrate, isolate, hydrolysate), read our whey guide.

CreamyClassic whey

Milky flavours (chocolate, vanilla, cookies), milkshake texture, mixes with water or milk. Also great for cooking: porridge, pancakes.

RefreshingClear whey

Fruity or iced tea flavours, juice-like texture, water only. Lighter in the mouth, especially after a sweaty session.

Tonic Food tip: many customers keep both: a chocolate whey for breakfast, a clear whey after training. Both provide milk protein of the same quality.

Our 6 clear whey proteins compared

Values come from the labels, for one serving as recommended by the brand.

Label values as of 05/11/2026, for the reference flavour. They vary slightly by flavour: the product page is the reference.

Our takeaway: for the same 30 g serving, whey-based clear proteins are on a par (about 25 g of protein). The difference is in taste and choice of flavours: ESN Isoclear offers around ten (peach iced tea, cactus, mango…) and is the most requested; Body Attack comes in 900 g; Nanosupps Epic Juice goes for juice flavours (mojito, watermelon). Protein Water Clear Beef stands apart: its protein comes from beef, not milk.

How to mix it (and avoid the foam)

1Pour 500 ml of very cold water into the shaker, then the powder (30 g or the dose on the label)
2Shake for 15 to 20 seconds, no more: the more you shake, the more it foams
3Let it rest 1 to 2 minutes: the foam settles and the drink turns clear

A few ice cubes make it even nicer. Avoid milk, though: clear whey is made for water, and its tangy taste doesn't suit it.

Who is it for, and when?

IdealAfter training

A big cold glass when a milky shake doesn't appeal, especially after an intense session or in summer.

IdealIf you don't like milk

No milky taste or thick texture. Note: it is still milk protein.

HandyDuring the day

About 100 kcal per glass: a protein drink instead of a sugary one.

Not forVegans

Clear whey comes from milk. For a protein with no animal products, see our vegan protein guide.

Milk protein allergy: clear whey is still a milk protein, even if it doesn't look or taste like one. It contains very little lactose, but check the label if you are very intolerant. Only Protein Water Clear Beef, made from beef, contains no milk protein.

For protein, only EU-authorised claims count:

EU-authorised

Protein contributes to a growth in muscle mass and to the maintenance of muscle mass.

This claim may be used for a product providing at least 12% of its energy as protein: true, by far, of every clear whey in the comparison.

How much? One or two servings a day is enough for most athletes: what matters is your total protein for the day, which you can work out with our protein needs calculator.

The questions we get asked in store

What is clear whey?

A whey isolate (highly filtered whey protein) processed to stay clear in water. You drink it like a juice or an iced tea, with about 21 to 25 g of protein per serving.

What's the difference between clear whey and classic whey?

The protein is the same (whey), but clear whey is fruity, clear and light, while classic whey is creamy and milky. Clear whey is mixed with water only.

Why does my clear whey foam?

That's normal: shaking traps air in the protein. Shake briefly with cold water and let it rest 1 to 2 minutes; the foam settles.

Is clear whey vegan?

No, it comes from milk. For a vegan protein, you need a plant protein (pea, rice, soy…).

What is the best clear whey?

The whey-based clear proteins in our comparison all provide about 25 g of protein per 30 g of powder: choose the flavour first. ESN Isoclear is the most requested for its wide choice of flavours.

Can I mix it with milk?

It isn't recommended: it is designed for water, and its tangy taste doesn't go with milk. For a milk shake, choose a classic whey.
