Colostrum (Bovine) for Exercise Recovery

Research suggests that bovine colostrum supplementation may offer some localized immune support during and after exercise, though the overall evidence base is limited and findings are mixed. The most directly relevant study is a single randomized, double-blind, placebo-controlled crossover trial in endurance-trained male athletes, which found that colostrum increased salivary secretory IgA concentrations following exercise, pointing to a possible benefit for mucosal immune defense, while no significant effects were observed on systemic blood-based immune or muscle damage markers. Studies indicate that the broader immune and recovery effects of bovine colostrum in athletic populations remain unclear, and the researchers themselves called for further investigation before firm conclusions can be drawn. It should also be noted that two of the three linked studies in this review concern unrelated topics — parasite biology and cellular stress responses — and do not contribute meaningful evidence to the question of colostrum and exercise recovery, further highlighting how sparse the directly applicable research currently is.
