Bovine colostrum supplementation has been shown to increase lean tissue (muscle mass) in younger individuals. Eight to 12 weeks of bovine colostrum supplementation during a resistance training program increased lean tissue mass by 1.5 to 2 kg compared to increases of 0 to 1.2 kg while on whey protein supplementation. We have also recently shown that bovine colostrum supplementation increases muscular strength compared to similar amounts of supplementation with whey protein in men and women over 50y.
