Colostrum Prime Life contains a minimum of 35% immunoglobulins (lgGs), which is double the strength of typical colostrum products because it is from the first milking. Colostrum Prime Life is also rich in Lactoferrin. Colostrum Prime Life is collected within 12 hours of calving from pasture-fed cows (during non-winter months) and is freeze-dried (lyophilization process under -40° celcius). This low temperature processing ensures that the different colostrum immunoglobulin fractions and growth factors retain their biological activity and are not denatured.
