N-ISO is 100% PURE Hydrolyzed Whey Isolate with no other sources or blends of slower non-hydrolyzed proteins. The reason why Hydrolyzed Whey Isolate absorbs so quickly, is because it has been partially pre-digested already, so your body doesn’t have to work as hard to break it down. We have used natural enzymes to provide biologically natural protein fragments that have the highest value for muscle recovery. This also ensures that N-ISO tastes amazing, since it prevents some of the bitter hydrophobic amino side chains from over-exposure. Inferior hydrolysate proteins can smell and taste horrible because they use harsh acid treatments to break down the proteins with no selectivity.Premium processing parameters make all the difference! N-ISO has been purified under cold temperature conditions to preserve protein structure and cross-flow membrane micro and ultra-filtered to remove fats, sugar and salt. The removal of nearly all the fat and all the lactose contributes to the incredible purity of N-ISO and rapid absorption.
