The Organic Protein Company
The Organic Protein Co - Pure Unflavoured Organic Whey Protein Powder | Additive Free, Undenatured, Bioactive, UPF Free, Emulsifier Free, Primarily Grass Fed, Vegetarian, Gluten Free – 400g
Free Shipping
Why We Love It
  • Pure, organic grass-fed protein.
  • Fast and easy digestion.
  • Ensures nutrient transparency.
Main Highlights
  • JUST ONE INGREDIENT: No chemicals, additives, ultra-processed foods (UPFs), sweeteners, flavourings, emulsifiers, thickeners, or any of that nonsense. Just pure organic whey protein from primarily grass fed cows grazing on open pastures in the UK and other European countries. Batch tested, with nutritional test certificates published for every batch, from an independent lab
  • UNDENATURED & BIOACTIVE: With naturally occurring Alpha Lactalbumin, Beta Lactoglobulin, Immunoglobulin G (IgG), and Lactoferrin. These useful bioactive proteins & antibodies are also found in human breast milk (except for B. Lactalbumin). With too much heat they’re denatured, so they can’t be utilised by our bodies. Good news: 3rd party testing shows 80% of our whey protein remains completely undenatured. Denatured whey protein is still valuable muscle food, just without the bioactive benefits.
  • CLEAN CREAMY TASTE: Gently filtered from fresh whey at a cutting-edge ceramic cold filtration facility without any chemicals or excessive heat. The result is a delightful clean creamy taste, free from weird flavours, odd aftertastes, and absolutely no grittiness at all. This almost a totally flavourless protein powder, if not for the irresistible creaminess.
  • PREMIUM VEGETARIAN PROTEIN: A natural vegetarian protein powder, packed with highly bioavailable naturally occurring essential & branched chain amino acids (BCAAs). Our bodies are unable to produce these vital building blocks of healthy muscle tissue, so dietary sources are needed. We use fresh liquid whey, a by-product from cheesemakers using friendly bacteria to lightly ferment the milk in order to separate the curds from the whey, therefore no animal rennet is needed.

  • VERSATILE: Our vegan protein powder is much better and loaded with essential nutrients than any artificial whey nutrition protein. It is perfect for smoothies & baking, or simply shake it with water or plant milk for a natural "planty" taste! Ideal for any diet, our protein powder vegan adapts to your culinary needs while providing great nutrition.
  • SMART NUTRITION: Our Lean Protein Powder is for clean, low calorie nutrition with organic protein to support muscle growth and aid fat loss. Choose our plant-based unflavored protein powder over whey isolate protein powder for the essential nutrients your body needs to stay fueled and perform at its best every day.
