We source our ingredients from family owned farms, exclusively in the UK and Ireland. We gently cold filter our whey protein isolate from 100% certified grass fed dairy.

BENEFITS OF OUR GRASS FED LOW LACTOSE WHEY ISOLATE

Our whey protein isolate contains a complete range of essential amino acids and over 5g of Branched Chained Amino Acids (BCAA’s) per serving! Through our cold-filtration process, we are able to remove all measurable amounts of the lactose typically found in milk-based protein powders. By doing this, we create an ultra pure whey isolate with very little to no lactose at all; providing an ideal source of complete protein needed for muscle protein synthesis, without any of the sensitivities or discomforts that may be associated with other milk-based protein products. NO FILLERS, NO MARKETING GIMMICKS, NO GAMES!
WE ARE OBSESSED WITH QUALITY
We filter our 100% grass fed protein isolate without the use of high heat, bleach, chemicals or processing agents. Our process is not easy and is time consuming, but it allows us to create a whey isolate in its purest form, with little to no lactose, an amino acid profile of the highest levels, undamaged, and with the most nutritional value.
Our isolate is filtered from certified grass fed dairy cows never treated with any growth hormones (certified rBGH and rBST free) and from milk never treated with any GMO ingredients or additives.
The entire team at John’s Killer Protein® works hard to build and maintain relationships with a cooperative of dairy farmers in the UK and Ireland who are dedicated to sustainable and eco-friendly farming practices and who genuinely care about the wellbeing of their cows.
