During milk or cheese production, rennet (composed mainly of an enzyme, rennin) is often used to facilitate coagulation of causing a separation of curds and whey.
Traditionally, rennet is animal-derived, extracted from the stomachs of calves. Calves produce rennet to help digest their mothers’ milk proteins. However, non-animal rennet (plant- or microbial-derived) has widely replaced animal rennet in response to increasing demands of groups with certain dietary restrictions.
Isagenix respects the rights of consumers to know if the dairy ingredients such as whey used in our products have been produced with animal or non-animal derived rennet. As is consistent with our high standards of sourcing dairy from New Zealand small family farms that allow their cows to enjoy a quality life on the pasture, the company also sources from producers who use only non-animal, non-GMO rennet.
