Our Super Serum Protein is a beef protein that is high in heme iron which has been clinically proven to show improved recovery times in human tissue regeneration. We source the beef from grass fed cattle that are non-gmo and raised antibiotic free in Sweden. It's the leanest, cleanest and most bio-available protein on the market. It also has a neutral PH whereas whey protein is very acidic. Super Serum Protein comes in Chocolate and Vanilla flavors.
