What are you actually paying for?
Search for whey protein isolate and the products can start looking very similar. High protein. Low carbs. Low fat. So when one bag costs around $60 and another is closer to $100, it’s reasonable to ask: why pay more?
Taste, sweetness, texture and mixability can vary even when two products have similar nutrition panels. If you use protein most days, those differences become part of your daily routine.
That question helped shape The Whey Co. The Australian brand was developed after its founder compared premium whey isolates with cheaper alternatives and found that the numbers on the label didn’t tell the whole story.
Here are five things worth comparing alongside the price:
Taste
Do you enjoy it with the water or milk you actually use? A flavour you like makes a daily habit easier to keep.
Sweetness
Think beyond the first sip. A rich, dessert-style shake may suit you; you may prefer something lighter every day.
Texture
Look for a drinking texture you enjoy. Grittiness, persistent clumps and excessive foam can all affect the experience.
Mixability
Your preparation matters. Find out how the powder mixes using a shaker, spoon or blender, depending on your routine.
Ingredients
Check the protein source, flavourings and sweeteners. Choose a formulation that fits your preferences and dietary needs.
The $60 WPI that changed the brief.
The founder of The Whey Co had already been using premium whey isolate when he decided to try cheaper WPI products. On paper, the protein numbers looked similar. Once mixed, one of the products gave him a very different experience.
“I put it in the blender and it just blew up with foam. I had this huge layer of foam on top, then clumps underneath it.”
The Whey Co founder

Price alone doesn’t tell you how a protein will behave. This experience did, however, become part of the product brief: the protein numbers had to be right, and the shake had to be enjoyable after you’d worked through half the bag.
Meet a WPI made for lighter sweetness.
Less sweetness.
More thought about every day.
The Whey Co uses European-sourced whey protein isolate. Its flavoured range combines natural flavours with thaumatin for sweetness, with the sweetness deliberately pulled back.
The aim is a lighter, less overpowering flavour, particularly with water. For people who find intensely sweet shakes tiring after a few weeks, that’s a meaningful point of difference.

“Would we actually want to drink this every day? If the answer wasn’t yes, we weren’t finished.”

The brand also focused on texture and mixability. Anyone who has bought a protein they struggle to finish will understand why these details matter.
“It’s not overly sweet so no sickly after taste. Mixes really well with no clumps”

It depends on what you value. If a cheaper WPI meets your nutrition needs and you enjoy drinking it, it can be a good choice.
If you’re regularly leaving a bag unfinished because it’s too sweet, difficult to mix or unpleasant to drink, the price per bag only tells part of the story.
About $1.21 more per shake.
A $60 bag is about $1.82 per serve.
A $100 bag is about $3.03 per serve.
That extra cost has to be worth it to you. The case for paying more is strongest when the formulation suits your taste and makes protein easier to fit into your routine.
Worth a closer look if…
- You find many shakes too sweet.
- You want isolate as the only protein source.
- You prefer naturally flavoured options.
- You care about the daily drinking experience.
Check your preferences if…
- You love intensely sweet dessert flavours.
- The lowest price is your main priority.
- You need a dairy-free protein: whey contains milk.
Start with a flavour that suits you.
Explore the range before you commit. The finished protein content varies by flavour, so compare the nutrition panel for the bag you’re choosing.

Natural Vanilla
A gently sweet vanilla option for a daily shake, smoothie or yoghurt bowl.
Dark Cocoa
For cocoa lovers who prefer a lighter sweetness. Try it with water or milk.
Unflavoured
The simplest option in the range, ready to add to your own shakes and recipes.
A few useful answers.
Does a higher price mean a better WPI?
No. Compare the finished nutrition panel, ingredients and how the product fits your preferences. The mixing example in this article describes one founder-supplied comparison; it doesn’t establish that every expensive WPI is better than every cheaper one.
Does “WPI 90” mean every flavour is 90% protein?
Check the finished product’s nutrition panel. In this range, the supplied packs show 27g protein per 30g serve for Unflavoured, 25g for Natural Vanilla and 24g for Dark Cocoa. Those amounts correspond to 90%, approximately 83% and 80% respectively.
What if I don’t enjoy the taste?
The Whey Co advertises a Taste Promise on its product page. Read the current refund terms there before placing your order.
See the product page and Taste PromiseCan I use it if I need a dairy-free protein?
No. Whey comes from milk. Check the full allergen and ingredient information for any product you’re considering.
