There are free SH-groups in all pure whey protein concentrates. As a result of our patented activation process the Activated Whey Protein (20 % of the Actiwhey®) contains three times more free SH-groups than regular whey protein concentrates.
The most comprehensive studies so far on the positive effects of free SH groups on humans are the ones we are referring to. These studies and results are still valid and unrivalled. If there would be more recent studies on the use of free SH-groups, they would most probably violate the process and application patents of Uniq.
