Some research suggests that lectins, a type of protein that occur naturally in plants but don’t offer nutritional value, can disrupt the gut lining. During the water-based (not chemical) isolation process, lectins are removed from Nuzest's pea protein isolate to further support your gut.
"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. Made from premium European golden peas and free from dairy, gluten, gums, and unnecessary additives, it’s highly digestible and well tolerated. Beyond its clean profile, it provides quality protein to support nutritional balance, sustained energy, muscle recovery, and blood sugar regulation. For anyone needing a reliable, gut-friendly protein that truly delivers, this is my go-to."
“Disturbances to the balance of ‘good’ and ‘bad’ microbes in the gut (dysbiosis) can affect both nourishment and growth and conditions ranging from metabolic states like obesity and type2 diabetes, functional gut disorders, inflammatory conditions, cardiovascular disease, and mental health challenges.”
"Nuzest is in every place of my car, in my boat, it's everywhere. There are sachets, shakers, and tubs all around. I'm a huge fan and it's helped my recovery as well. I take it religiously every day, twice a day sometimes. It helps with muscle recovery and that allows me to train back-to-back each day."

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.

Your new daily habit.
Clean Lean Protein is designed to gently support muscle growth and recovery with 100% plant-based ingredients.
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.
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.

This is my favorite for summer smoothies with fruit. I have not been a fan of protein powders in the past because of taste, texture, or both. This protein powder is perfect for me. I have recommended it to others who are also happy with it.
"We love this protein powder. It tastes really good, and I’ve noticed my snacking has gone down. I feel leaner and more energised when I take it daily, especially when replacing breakfast with a shake."
“I have IBS and other digestive issues and haven't had any issues with this! No bloating either!”
“I didn't know what I was missing until now! Having had digestive issues for years (IBS, C-Diff, SIBO) this has been a literal godsend. It's gotten me through flares, with ZERO symptoms or after-effects. Tastes clean, no tummy upsets, no bloating - I hope it never goes out of stock!”
Pea protein is easily digestible, and is well tolerated by the body - making it suitable for even more sensitive stomachs. Additionally, our pea protein isolate doesn't contain anti-nutrients or appreciable amounts of lectins or phytic acid — usually present in legumes that cause bloating and digestive disruption.
Pea protein isolate can provide the same benefits as animal proteins such as whey but without the dairy allergen and potential digestive side effects. When compared with whey, pea protein is digested slightly faster however it is absorbed slower and is more satiating - keeping you fuller for longer.
When combined with a healthy diet and lifestyle, pea protein isolate can support muscle growth, as well as repair and recovery.
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.
