Colostrum is a great source of IgA antibodies that have been known to help support and build up a healthy immune system.

Supplied to all first born mammals, colostrum comes from mother’s first milk and helps nourish a newborn. Four Leaf Rover Colostrum is from bovine and is dense in proline-rich-polypeptide (PRP), which has been researched to help relieve allergy symptoms and autoimmune disease.


Our bovine colostrum is only from grass-fed cattle raised in pristine New Zealand. The colostrum is shared with the calf and is collected from small, ethical farmers. 

Every batch of colostrum is tested to be free of hormones and antibiotics and is tested for its antibody content.
