When your body stop making rennet?

Rennet is an enzyme primarily produced in the stomachs of young mammals and is essential for digesting milk. As humans age, particularly after weaning, the production of rennet decreases significantly, often ceasing entirely in adulthood. This reduction is a natural part of development, as the body adapts to a diet that no longer relies on milk. Consequently, adults typically do not produce rennet, but they can still digest dairy products through other enzymes.
