The Organic Protein Company

Why we love it

Pure organic grass-fed ingredient.
Quick body absorption.
Ideal for vegetarians.

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.
EASY TO DIGEST: Each 25g serving contains 19.8g of protein that is fast to digest, so our bodies can break it down quickly to get to the good stuff. Whey protein is one of the mostly highly bioavailable protein sources, put to work more speedily and efficiently by our bodies than just about any other protein source. Fun fact: skimmed milk powder = 50% lactose. Our whey protein = 3% lactose, a nearly 95% reduction, so those with lactose sensitivity are less likely to experience bloating & other issues.
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.
