RAW CBUM Itholate — 25g Whey Isolate, 110 Calories, Informed Protein Certified

RAW Nutrition CBUM Itholate (ISO Protein)25 grams of protein at 110 calories, from 100% micro-filtered whey isolate.

That is roughly 80% protein by weight.Work that out on any protein tub and you learn a great deal quickly.

PRODUCT LABEL

RAW Nutrition CBUM Itholate (ISO Protein)

25 grams of protein at 110 calories, from 100% micro-filtered whey isolate. Zero fat, 1 to 3g carbohydrate, and Informed Protein certified for banned substances.

There is one number that tells you most of what you need to know about an isolate, and this one is worth doing.

80% protein by weight — the test worth applying

The scoop is 31 grams and it delivers 25 grams of protein. That is roughly 80% protein by weight.

Work that out on any protein tub and you learn a great deal quickly. The remainder of any scoop is flavouring, sweetener, gums and whatever else is in the formula — so the higher that percentage, the more of what you are buying is actually protein.

A concentrate-led blend typically lands nearer 65 to 70%. Products carrying creamers, fillers or added carbohydrate go lower still. 80% is where a genuine isolate sits, and it is a far more reliable test than anything on the front of the tub.

The ingredient list backs it up and is unusually short: whey protein isolate, natural flavours, salt, a gum blend, and sucralose. No proprietary blends, no creamers, nothing padding the weight.

Micro-filtration, and why it produces this macro profile

Whey isolate is made by filtering whey concentrate further to remove fat, lactose and carbohydrate, concentrating the protein fraction.

Micro-filtration does this using physical membranes rather than heat or chemical processing. That matters because heat denatures protein — it unfolds the molecule from its natural structure. The amino acids survive either way, so a heat-treated whey still delivers its grams, but membrane filtration keeps the protein closer to its native state.

The practical result is on the label: 0g fat, 1 to 3g carbs, and 110 calories for 25g of protein. That is about as lean as whey gets, and it is why isolates suit a cut.

It also means very little lactose, since lactose is removed alongside the fat. If standard whey bloats you, this is a considerably better bet.

Informed Protein certified

This is the differentiator most retailer pages skip, and it is a real one.

Informed Protein certification means the product is independently tested for banned substances by LGC, one of the major sports anti-doping laboratories. That makes it usable by tested athletes.

Most proteins on most shelves carry no certification at all. It is worth nothing if you do not compete — but it costs you nothing either way, and it is a reasonable proxy for a manufacturer taking quality control seriously.

How to mix it

One scoop into 6 to 10 ounces of cold water. Isolates mix thin by nature — use less liquid for a thicker shake.
The gum blend (guar, acacia and xanthan) is there to improve mouthfeel, which is why it drinks better than an unformulated isolate.
Post-workout or any time. Isolate absorbs quickly, which matters most after training.
Good in oats, yoghurt and smoothies. Less good for baking — pure isolate dries baked goods out. Use a blend for that.

Who this is for

Anyone cutting — 25g protein for 110 calories with zero fat is about as efficient as it gets
Tested athletes, given Informed Protein certification
People who bloat on standard whey, since micro-filtration removes most of the lactose
Anyone who wants the shortest possible ingredient list
People who want a protein that mixes thin and clean rather than thick and creamy

Who this is not for

If you want a thick, creamy, dessert-like shake, an isolate is thin by design. A concentrate-led blend or casein gives you that.

If you bake with protein, use a blend — pure isolate dries out.

If you have a milk allergy rather than lactose intolerance, no whey is suitable. The allergen is the protein itself.

If you avoid sucralose, this uses it.

If cost per gram is the priority, a concentrate blend is cheaper. You are paying for the filtration and the certification.

Stack it with: creatine, which mixes in without affecting flavour. Or Super Carb after training if you want carbohydrate alongside.

Frequently asked questions

Is Itholate the same as CBUM ISO Protein?
Yes. It is sold under both names — "Itholate" is Chris Bumstead's own pronunciation of isolate.

How much protein per scoop?
25g from a 31g scoop, which is roughly 80% protein by weight — where a genuine isolate should sit.

What does micro-filtered mean?
The whey is filtered through physical membranes rather than processed with heat or chemicals, removing fat, lactose and carbohydrate while keeping the protein closer to its native state.

Is it good for lactose intolerance?
Yes, generally. Micro-filtration removes most of the lactose along with the fat. A milk allergy is a different matter — that reacts to the protein itself.

Is it tested for banned substances?
Yes, Informed Protein certified, independently tested by LGC. Most proteins carry no certification at all.

How many calories?
Around 110, varying between 100 and 120 by flavour. Check your specific tub if you are tracking closely.

Can I bake with it?
Not ideally. Pure whey isolate denatures under heat and dries baked goods out — a whey and casein blend works better.

Why does it mix thin?
Because there is almost nothing in it but protein. Use less water for a thicker shake.
