The Whey Co protein

Not all whey is the same

Two tubs can both say "whey isolate" and be completely different. Here is how to tell.

Isolate, not concentrate
✕ Cheap tubs
Concentrate (WPC). Around 70 to 80% protein, plus lactose, fat and carbs.
✓ Ours
Isolate (WPI). Around 90% protein, little else.
Read the label, not the front
✕ Others
"Isolate" on the front, cheaper concentrate listed in the ingredients. A blend.
✓ Ours
One protein source. Pure isolate, never padded with concentrate.
Where the milk comes from
✕ Others
The cheapest whey on the world market, bought wherever it lands cheapest.
✓ Ours
Grass-fed whey from cows raised on pasture.
The protein number can be faked
✕ Others
Padded with cheap added aminos to inflate the number. It is called amino spiking.
✓ Ours
Every gram is real whey. Compare per gram, not per scoop.
How it is sweetened
✕ Others
Sucralose. Cheap, and that is the fake aftertaste.
✓ Ours
Thaumatin, a natural sweetener that comes from a fruit.

So why is another "isolate" cheaper? Usually it is a blend, cheaper milk, a padded protein number, or fillers. Now you know how to check.

Guarantee

Trying a new brand shouldn't be a gamble.

We know you haven't heard of us. That's exactly why the guarantee exists. Order a bag. If it isn't the cleanest-tasting protein you've had, request a full refund. No hoops, no return postage games. We'd rather refund a bag than have you settle for sucralose.

What customers say

Why WPI 90

Isolate strips out more of the lactose than concentrate does, which is why people with mild sensitivity often find it easier to tolerate. It's still a dairy product though, and contains milk.

Ingredients chosen for quality

High-grade WPI 90, natural flavours, premium cocoa and thaumatin, selected for the final product, not the lowest cost per tonne.

Lower sweetness, deliberately

Lightly sweetened so you can drink it every day without it turning sickly. If you're used to very sweet powders, you'll notice the difference on the first shake.

Smooth mixing

Shake 30g with 200-250ml of water or milk. No grit, no stubborn clumps, no gums doing the work a good isolate should do on its own.

Lower lactose than concentrate

WPI removes more lactose during processing than whey concentrate, while still being a dairy product.

Questions, answered straight

Why is it more expensive than the big bulk brands? +
WPI 90 costs more to produce than concentrate, and thaumatin costs several times what sucralose does. That's reflected in the price and if it doesn't feel worth it once you've tried it, you get a full refund.
How much protein per serve? +
Up to 27g per 30g serve, varying slightly by flavour. Unflavoured has the simplest formulation and the highest protein per serve. Full nutrition panels are on the product page.
What does "lightly sweetened" actually mean? +
This isn't a dessert-style protein. Expect a lighter sweetness, natural flavour and a clean finish with no lingering artificial aftertaste. If you love very sweet shakes, start with Dark Cocoa mixed in milk.
What is thaumatin? +
A naturally derived sweet-tasting protein from the katemfe fruit of West Africa. It's intensely sweet, so only a tiny amount is needed. No artificial sweeteners required.
I'm sensitive to lactose, can I use it? +
WPI contains less lactose than whey concentrate, which many people with mild sensitivity find easier on the stomach. It is still a dairy product and contains milk.
How long does a bag last? +
Each 1kg bag holds roughly 33 serves, about a month at one serve a day. Subscribing saves 10% and lands a fresh bag before you run out.
When should I take it? +
Whenever it helps you hit your daily protein target. After training is convenient, but with breakfast, in a smoothie or stirred through oats works just as well.
