Rating (out of 5): 2

Bovine-derived supplements, particularly bovine colostrum and hydrolyzed bovine protein, are sometimes used as athletic and exercise aids. The rationale for their use is based on their rich content of immunoglobulins, growth factors, and proteins, all of which may, in theory, support muscle recovery, immune function, and overall athletic performance. Some clinical studies have explored the effects of bovine colostrum supplementation in athletes, noting modest improvements in exercise performance, lean body mass, and reduced incidence of upper respiratory tract infections. However, the magnitude of these effects is generally small and sometimes inconsistent across studies. Meta-analyses suggest that while there may be some benefits, particularly related to immune function during periods of intense training, the evidence is not robust or universally supportive for significant enhancements in strength, endurance, or overall performance.

Bovine collagen and gelatin have also been marketed to athletes for joint health and connective tissue repair, but scientific support for their effectiveness in these roles is limited. Overall, the use of bovine products in exercise and athletic contexts is grounded in some scientific evidence, but most studies are small, short-term, or methodologically limited, yielding a modest evidence rating. Thus, while there is some scientific validation for their use, especially for immune support in athletes, the overall evidence is not strong (rated 2 out of 5).
