Our verdict on Bulk Clear Whey Isolate
Bulk Clear Whey Isolate suits people who want a juice-style shake after training rather than a milky one. It carries 80g of protein per 100g with 0.4g of sugar and 0.7g of fat. The name oversells it: the ingredient list opens with whey protein hydrolysate, not isolate. The serving is 25g, so each shake gives 20g of protein rather than the usual 24g to 25g. Flavour is where it fails for people, so try a 500g bag first.

Pros and cons
Pros
- Genuinely refreshing post-session when milky shakes are unappealing
- 0.4g of sugar and 0.7g of fat per 100g, so it costs you almost nothing on a cut
- Salt is 0.04g per 100g, a fraction of what the concentrate carries
- Mixes in water in a bottle, so it works as a gym-bag drink rather than a kitchen shake
Cons
- Named Isolate, made from hydrolysate. Check the ingredient list if that distinction matters to you
- The serving is 25g, so 20g of protein per shake, not the 24g to 25g you get from a standard tub
- Flavour draws consistent, specific criticism from buyers, more than any other Bulk protein we looked at
- Contains polydimethylsiloxane and silicon dioxide as anti-foaming agents, which is normal for clear whey but new to most people reading the back of the bag
Nutrition and ingredients
From the manufacturer’s published label (Source). Read the ingredient list before the name. The protein here is whey protein HYDROLYSATE, not isolate: hydrolysate is what makes it dissolve clear instead of going milky. The name is the odd one out on the label, not the powder.
A 25g serving, not the 30g most powders use, so 20g of protein per shake rather than 24g or 25g. Compare tubs on cost per 25g of protein, not on price per bag, or this one looks cheaper than it is.

- Pack sizes
- 500g, 1kg, 2kg
- Flavours
- This is a juice-style drink, so flavour is the entire experience rather than something you mask with milk. It is also the thing buyers complain about most, by name.
- Third-party testing
- Informed Sport: no evidence found. No third-party batch testing is claimed on the product page.
- Made by
- Sports Supplements Limited, trading as Bulk, Colchester, Essex
What the maker does not publish
- Bulk does not explain anywhere on the product page why a powder built on whey hydrolysate is sold as Clear Whey Isolate.
- Buyer complaints cluster on specific flavours rather than the product as a whole, but Bulk publishes no per-flavour rating, so there is no way to tell from the listing which lines are the safe ones.
Method: nutrition figures come from the manufacturer label. Cost per 25g of protein is the pack price divided by the grams of protein in the pack, multiplied by 25.
What buyers say
Quoted word for word and linked, so you can read the full review or thread.
Recurring themes
- Lemon iced tea is the flavour buyers criticise most often, with verdicts ranging from "mouldy milk" to "drinkable at least".
“I always use bulk for my protein powder needs. Their clear whey isolates are my particular favourite. Very good, very clear and come in a range of different flavours.”
“The taste is extremely synthetic.”
“Ordered lemon ice tea clear protein. It tastes of mouldy milk and strawberry.”
“Lemon tea clear protein bad test but drinkable at least.”
Quick answers
Is Bulk Clear Whey Isolate actually an isolate?
No. The ingredient list starts with whey protein hydrolysate, which is broken down further and dissolves clear rather than milky. It is a good protein source at 80g per 100g, but the name does not match the label.
How much protein is in a serving of Bulk Clear Whey Isolate?
20g in a 25g serving. That is a smaller scoop than the 30g most powders use, so count it as 20g and adjust the rest of your day.
Is clear whey better than normal whey after training?
Not nutritionally. It does the same job in a form that is easier to drink when you are hot. It has less fat and salt per 100g than Bulk Pure Whey Protein but costs more per 25g of protein, so it is a preference purchase.
Which flavours should I avoid?
Lemon iced tea and cola draw the most direct criticism in public reviews, though we have not tasted them ourselves. Buy the 500g bag of any flavour you have not tried.
