Why We Love It
  • Natural and high-quality ingredients.
  • Supports muscle growth effectively.
  • Great taste without extra calories.
Main Highlights
  • The first protein of 100% natural origin: premium protein powder made from high-quality ingredients without additional frills. It is rich in highly usable protein, including BCAAs that support muscle growth and retention.
  • From the milk of free-range cows: the cows are fed with grass for at least 10 months a year. As a result, it has a cheaper fatty acid composition than the milk of cows that receive compound feed.
  • Maximum ease of use: Whey protein has a similar bioavailability to meat and is therefore best suited for the human body. It has excellent digestibility and contains a high proportion of essential amino acids.
  • Good macronutrient ratio: Our protein powder has less than 125 kcal per serving, is naturally protein rich and contains little sugar and fat*, making it a great aid for a simple, high-quality protein replenishment.
  • Natural sweetener from stevia leaves: the stevia plant allows us to produce a high-quality sweetener with steviol glycosides. They have no effect on blood sugar levels, are 200-300 times sweeter than sugar and are considered a safe calorie free sweeteners for our whey protein powder. Note: measuring spoon not included

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.
