Colostrum PRIME LIFE is collected from American pasture cows and processed within 12 hours of calving. Colostrum Prime Life™ undergoes lactose removal and is then freeze-dried to preserve the biological activity of its special proteins. Colostrum Prime Life™ contains over 25% immunoglobulins (IgGs), double the strength of typical colostrum products. Colostrum Prime Life is lactose reduced and is rich in lactoferrin.
