Brief Summary

Bovine colostrum is the milk produced by cows immediately after calving. It contains high levels of proteins that improve immune protection and may act to prevent colds. During intense training, athletes often have compromised immune function. This may be especially true in club-level rugby players who abruptly start high intensity training in the spring in preparation for their competitive season. Our study will assess the effects of supplementing these players with bovine colostrum during this intense training. Thirty-six players will be recruited; half will consume colostrum during the 8 weeks of early-season training and half soy protein. The investigators predict the bovine colostrum supplement will improve health during the training and increase fitness levels.
