Thrive Colostrum Powder is an all-natural supplement that aids pets who deal with seasonal or food allergies—made with freeze-dried bovine colostrum sourced from USDA Grade A dairy cows from the USA. Bovine colostrum contains PRP, proline-rich polypeptide. PRP is known to stimulate inactive immune systems and allow it to deal with diseases and suppressing overactive systems that are prone to cause allergic reactions or autoimmune disorders. This unique powder supplement can be offered as a treat 20-30 minutes before mealtime or mixed into their food, and its pleasant taste ensures that picky eaters will not turn their nose away.
