The benefits of colostrum, without the dry shoveling. Our new colostrum capsules improve your wellbeing, nourish your gut and support your immune system.** Colostrum is a baby mammal’s first food, providing nutrients and immune support. Shortly after cows are born, they release colostrum to support growing calves (but don’t worry, cows produce more colostrum than a calf needs; instead of wasting it, we use the excess). We call this our Calf-First Promise.
