The problem was never the protein

Blame the bloat and the heavy gut on protein? It isn’t the protein. It’s the gums, fillers and sugar packed in with it. Clean Lean Protein leaves all of that out: 25g of yellow pea protein, 0g sugar, nothing you have to forgive.

02

The best protein is the one you take

The best protein is the one you’ll actually take every day. Dread it and you skip it, and skipped days are where your results quietly leak away. Clean Lean Protein goes down light, mixes smooth and never turns to sludge so taking it stops being something you have to talk yourself into.

Clean Lean Protein is one serve at 125 calories, taken once a day.

03

Complete, not almost complete

Plenty of proteins give you the grams but miss the amino acids that do the building. Not this one. Every 25g serve carries all nine essential amino acids: a complete protein, and a real rival to animal sources.

04

Absorbs clean, so nothing’s wasted

You paid for 25g of protein, so use all of it. Yellow pea protein digests and absorbs easily, so it goes straight to work on recovery, repair and growth. No weight, no wait, nothing sitting heavy after. You feel the difference as no difference.

05

25 grams that pull their weight

25g per serve is a real, working dose, not a token scoop there to justify the label. It’s the floor a training day is built on. Check the protein per serve, and check what’s carrying it. That’s what decides whether it’s doing anything.

Not protein alone.
30 actives, one serve.

Protein is just the headline. Every serve also carries 30 actives: the vitamins, minerals and micronutrients your body burns through, plus a natural source of iron. That’s 31 in one scoop, at 125 calories, once a day. Your whole shelf, handled.

You’ll feel it before you see it

You’ll feel it before you see it. Week 4, recovery keeps pace and the heaviness other proteins leave behind is gone. Week 8, staying consistent is easy because nothing about it is a chore. Week 12, the difference shows. Results vary with training, diet and consistency.

The questions everybody asks.

What is Clean Lean Protein?

A complete daily protein built on 25g of yellow pea protein all nine essential amino acids, a genuine rival to animal sources, and 30 actives around it, in a single 125-calorie serve. Gluten-free and dairy-free, easy to digest, and clean enough to take every day without a second thought.

How much protein do I actually need?

Most guidance for people training for lean mass lands somewhere around 1.6 to 2.2g per kilogram of bodyweight a day. The exact figure matters far less than hitting a sensible one consistently, which is where most people fall short, not on the number itself, but on the days a meal gets skipped. 25g in one serve is a floor you can put under those days.

Will it bloat me or sit heavy?

No. The bloat and heaviness people blame on protein come from gums, fillers and cheap powder, not from the protein itself. Yellow pea protein is easily digested and absorbed, and there’s nothing in here to sit heavy so it goes down clean and gets out of your way.

Is pea protein a complete protein?

Yes. Clean Lean Protein carries all nine essential amino acids the ones your body can’t make on its own in every serve, which is what “complete” means. Yellow pea protein is widely regarded as a strong rival to animal proteins for recovery, muscle repair and growth, without the bloat that often comes with them.

How much protein, and how do I take it?

25g of yellow pea protein per serve one sachet or one scoop, shaken into 300ml of water or a beverage of your choice. One serve daily.

When should I take it?

After training is a useful window, but any time works this is a daily protein, not a pre-workout. The one that matters is consistency: a serve every day beats a perfectly timed one you skip. Take it whenever you’ll actually take it.

Who is it for?

Anyone who wants a clean, complete daily protein one that delivers 25g and 30 actives without the bloat, chalk or filler list. It isn’t a weight-loss product and it isn’t a replacement for meals.

How does it fit into my routine?

It’s the daily protein you build the rest of your routine around one clean serve that covers 25g of complete protein and 30 actives, so it does the work of a protein plus a multivitamin without the shelf of tubs. It doesn’t change your programme, and it isn’t a substitute for meals.

What if I don’t like it?

You’re covered by a 90-day full refund guarantee, and you can cancel or pause a subscription at any time. If it’s the flavour rather than the formula, the flavour promise lets you swap within 24 hours.
