Oxymin Colostrum: 100% pure premium colostrum is collected from first milking only, harvested within 16 hours of parturition (calving). Colostrum from first milking has significantly higher levels of proline-rich polypeptides (PRPs), immunoglobulins (Ig), and other important nutrient factors. Processed using low-heat flash pasteurization and indirect drying to preserve efficacy and bio-activity, the colostrum is then fat reduced to concentrate protein levels (approx 64%) and maintain the PRPs. Oxymin Colostrum is critically controlled at every step of production, sampled, tested and analyzed by advanced chromatography technology to ensure a pure, nutrient dense and microbially safe product for you to enjoy.
