Clinical dose
13g grass-fed whey protein + bovine colostrum per serving

Bovine colostrum contains IgG immunoglobulins and IGF-1 that support immune function and gut barrier integrity alongside the muscle-building benefits of whey. The lactase enzyme in the digestive blend specifically addresses the most common whey complaint (bloating). DIAAS 133 confirms exceptional amino acid completeness.
