Colostrum is a food produced by all mammals. Colostrum6 is bovine colostrum, which is 99% bioidentical to human colostrum. It is extremely potent and the most effective colostrum on the market because it is the only colostrum certified by a third-party to be pure, and is obtained within the first 6 hours of colostrum production. Colostrum6 is never diluted with transitional milk, nor is the ‘good fat’ that contains all of the vital nutrients removed from it. Ours is the ONLY Independently “Tested & Certified” 6-hour Colostrum–Tested and Certified by Dr. Don Lein, Professor Emeritus, Cornell University.
