Liposomal delivery (LD) is vital for the survival of colostrumâ€s delicate bioactives. LD protects the immune and growth factors which are critical to the repair and regeneration of all body tissue, as well as the activation and optimization of immune processes. LD ensures that these vital components can do their amazing work. Most bovine colostrum supplements on the market today do not have liposomal delivery to protect colostrum's health-enhancing components from the harsh stomach acids.
