"As a nutritionist, I see countless clients with digestive issues, food intolerances, or sensitivities - so finding a protein powder that’s both effective and gentle on the gut is a game-changer. Clean Lean Protein is one of the few I trust and recommend with confidence. "

Get started with Clean Lean Protein
Some clinical studies have revealed that 40% of adults experience functional gut symptoms weekly*—with microbiome imbalances directly linked to systemic inflammation, nutrient malabsorption, and even mood fluctuations. Some research conducted has shown 70% of your immune system resides in the gut**, while 90% of serotonin (your "feel-good" neurotransmitter) is produced there***. So it’s no wonder you feel ‘off’ when your gut isn’t working properly.

Why customers love us and take Clean Lean Protein
Good Gut Health For Everyone
As we age, our digestion naturally becomes less efficient—food moves slower, and our bodies absorb fewer nutrients from what we eat. Over time, this can lead to subtle nutritional gaps that affect how we feel and function.
Clean Lean Protein is formulated to help increase protein intake without the artificial flavours, preservative, sugars or nasties.
✔ Post workout muscle recovery
✔ Healthy snack - great on-the-go nutrition
✔ Contributes towards increased protein consumption
✔ Supports healthy aging
It's science-backed nutrition designed for active bodies—helping you get more from every sip.
How we're different
Not all proteins are created equal. We've intentionally selected European Golden Peas - because what matters isn't just what's in the tub, but what your body can actually use.
Why Golden Pea Protein
✔ European Golden pea protein instead of whey - suitable for vegans, vegetarians, or those with allergies and intolerances.
✔ Crops are primarily harvested in Northern France, an area celebrated for its high-quality soils, clean environment and sustainable farming practices.
✔ Our pea protein isolate offers the same benefits as animal proteins but without the dairy allergen and digestive side effects.
✔ When compared with whey, pea protein is digested slightly faster; however, it is absorbed slower and is more satiating - helping to keep you fuller for longer.
Full transparency
We believe in full ingredient breakdowns— so you know exactly what you’re getting. Unlike other plant-based or whey based proteins, Clean Lean Protein delivers a comprehensive, synergistic blend designed to support digestive regulation as well as supporting muscle growth and repair.
Transparency you can trust. Every ingredient is clearly listed, scientifically studied, and independently tested—because your health deserves nothing less.
Why these choices matter
No lactose bloat. No soy irritation. Just, gut-friendly protein that actually absorbs properly. Contains all 9 essential amino acids.
Clean fuel, full stop.

Our Story
A personal journey that became a global mission.
We all take good health for granted, until something happens that makes us rethink how precious it is.
For us, that moment came in 2005 when my daughter, Monique, was diagnosed with Multiple Sclerosis at just 22. But for many people, it is the simple realisation that they want to live life to the full.
Monique’s prognosis was confronting. The future felt uncertain, and we were told there was little we could do. But we weren’t willing to accept that. We began searching for answers, speaking to health professionals, scientists and nutritionists around the world. Together we explored modern medicine, natural therapies and the role of nutrition in long-term wellbeing.
What we discovered was simple yet powerful: Good nutrition can help people feel better, support their longevity, and bring a sense of control back into their lives. That discovery sparked our mission.
