Primal Whey is an alternative whey concentrate supplement. What makes Primal Whey unique is that it contains absolutely no instantiser. When usual whey powder's are manufactured they undergo a process called instantisation at the original milk plant. Most of the time the ingredient added for this manufacturing step is Soy Lecithin (sometimes it will just be called 'Lecithin' in the ingredients lists on protein powders and foods).
We believe that less processing is best for maintaining whey protein powders healthy properties, so we get this whey before any instantisation processing steps have taken place.
