                                According to manufacturers and ethical sourcing standards, the vast majority of colostrum for supplements is sourced from surplus bovine colostrum, meaning it is collected only after newborn calves have received the vital nutrients they need. This practice is part of a "calf-first" policy designed to ensure animal welfare while utilizing a valuable byproduct from the dairy industry.
