GLP-1 friendly · Clear whey isolate · Peach iced tea
brim
A thin, clear whey isolate for people eating far less than they used to. It disperses in cold water instead of coating the tongue, so it drinks like a cordial rather than a meal you have to psych yourself up for.
- Clear whey isolate, so it mixes translucent rather than milky
- Sweetened well below the category norm
- Light and fruit-forward, not a dessert flavour
- Cold water and a glass. No shaker, no blender
Launching once samples clear a blind taste test and an independent laboratory assay. There is no checkout, pre-order or card capture until the product physically exists. The waitlist decides the flavour and the sweetness, and hears the launch price first.
- Independent batch assay, published on this page at launch
- UK blending and packing, manufacturer named once selected
- Skip or cancel a subscription any time
- Anything about a medicine or a symptom reaches a person
Solid badges are proved. Outlined badges are the specification we are building to, and each one becomes solid with its certificate attached or it comes off this page. We show you the gap rather than paper over it.
Why it is built this way
Four decisions, and the reason for each.
None of this is a feature list. Each one is a choice made because of something people eating far less than usual told us they could not get past.
Losing weight fast costs more than fat
When weight comes off quickly, some of what goes is lean tissue. That is not a marketing line, it is the consistent finding across the trial evidence, and it is the single reason this product exists rather than another flavour of the same shake.
~25% of total weight lost was lean mass across 22 randomised controlled trials of GLP-1 receptor agonists. Metabolism, 2025Protein contributes to the maintenance of muscle mass.
Why we built it around protein. Authorised GB register wording, used word for word, and the product meets the compositional condition behind it.
Concept imageryClear, because thick is the problem
Opacity in a protein drink comes from fat and milk solids. Filter them out and the liquid stops scattering light, and stops coating the tongue with it. What is left is thin, cold and finished in a few mouthfuls. If a creamy shake currently sits in front of you until it goes warm, this is the entire point.
Concept imageryDialled down, and published
Sweetness is the most common reason a tub gets abandoned after three servings, and it is the one specification almost nobody in this category will tell you. We are formulating well below the category norm and we will print the sweetener and the level on the pack. If your tastes have shifted and sugar now reads as cloying, that decision was made for you.
Concept imageryThirty seconds, start to finish
Cold water, a glass, a spoon. No blender to wash, no shaker to find, no bag of equipment. A protein you have to prepare is a protein you will skip on the day you feel worst, which is exactly the day it matters.
Concept imageryWhere it sits
Three formats. One honest table.
Not a competitor teardown. These are the three realistic ways to get protein into a day when you are barely eating, and each of them wins at something.
| brim clear whey | Traditional whey shake | Ready-to-drink protein water | |
|---|---|---|---|
| Protein source | Whey isolate | Usually concentrate, or a blend | Isolate or hydrolysate |
| In the glass | Thin, translucent, cold | Thick, opaque, creamy | Thin, translucent, cold |

| Carried in a bag | Yes, it is a powder | Yes, it is a powder | Heavy, it is mostly water |
| Batch testing shown | Independent assay published intended | Varies widely by brand | Varies widely by brand |
Anything in the brim column marked intended is the specification we are building to, proved on a finished sample before the mark comes off. It confirms with the assay attached, or it changes and we say so here.
How to drink it
Cold water. A glass. That is the whole ritual.
It is meant to be the easiest thing you do all day, not another task with instructions attached.
- Cold water, not milk It is designed for water. Milk defeats the point of a clear protein, and milk is the texture most people tell us they cannot face.
- Stir, rather than shake Provisional The target is a powder that disperses with a spoon in a glass, without a shaker and without lumps. Finished samples decide whether it earns that description, and we publish the answer either way.
- Drink it cold Cold blunts sweetness and lifts the fruit character. If your taste has changed, temperature matters more than it used to.
- Whenever it is easiest There is no window and no schedule. It is a drink you have when a drink is manageable, which for a lot of people is the whole reason it works.
Concept imagery. Final product photography pending.
Provisional means the target we are building to, proved on a finished sample before the label comes off. We confirm it or we change it, and we tell you which.

Before you ask
The awkward questions
When can I buy it?
Once samples clear a blind taste test and an independent laboratory assay. The product does not exist yet, so we are working through a shortlist of UK manufacturers and will publish the full specification before anyone pays for it. The waitlist sets the flavour and hears the price first.
What will it taste like?
Light, fruit-forward and closer to a cordial than a shake. Peach iced tea is the current direction rather than a decision. The waitlist helps choose it, and the waitlist tastes it first.
What is the protein per serving?
It is set at sample stage, once the formulation is final, and the full panel goes on this page the day it is. We publish a figure we can stand behind or none at all, which is why there is not one here today.
Why does it cost more than the big brands?
Because we are not trying to beat them on price and never will. The mass-market clear wheys sit around £1.30 to £1.50 a serving, on purchasing power we cannot match. What you are paying more for is a formulation built around tolerability rather than around grams, and an independent laboratory assay published on this page rather than supplied on request.
Can I take it alongside medication?
Speak to your doctor or pharmacist before adding any supplement, because they are the right people to answer it. We answer what is in the product, your prescriber answers what is right for you. Any message you send us mentioning a medication, a symptom or a medical condition reaches a person, never an automated reply.
What happens to my subscription if I stop needing it?
You skip it or cancel it, in one click, with no phone call and no retention script. A subscription that is hard to leave is a subscription nobody trusts joining.
Food supplement. Contains milk. Not a substitute for a varied and balanced diet or a healthy lifestyle. Do not exceed the recommended daily portion. Store out of the reach of young children. If you are pregnant, breastfeeding, under medical supervision or taking prescribed medication, speak to your doctor or pharmacist before use. Full ingredients, allergen declaration and nutritional panel are published before launch.
Made in the United Kingdom.
We are choosing a UK manufacturer to blend and pack it, not shipping it in and relabelling it, and we name them here once selected. Every manufacturer on our shortlist is asked for a batch certificate of analysis, an allergen declaration, their HACCP plan and their BRCGS audit grade before we place an order.
The evidence
Do not take our word for any of this.
Everything above that is a fact rather than a description has a source, and here they are in full. Read them and hold us to them.
None of these sources is about brim, and none of them is an endorsement of brim. They describe protein as a nutrient, the regulatory position in Great Britain, and what is happening in the market. If you think we have read one of them wrong, tell us and we will correct it in public.
Reviews
We will publish the bad ones too.
The first verified reviews land here.
When we launch, every review here will be tied to a verified purchase, published unedited, and left up whether it is five stars or one. If a batch runs late or a flavour misses, you will read it here first. We would rather earn a real 4.2 than buy a fake 4.9.
