Colostrum, the first form of milk produced by mammals immediately following delivery, is rich in immunoglobulins, growth factors, and antimicrobial peptides. Its use for supporting immunity and preventing infections, including common colds, has some scientific basis. Several clinical studies have investigated bovine colostrum supplementation and its impact on upper respiratory tract infections (URTIs), including colds. For example, randomized controlled trials have shown that bovine colostrum supplementation can reduce the incidence and severity of URTIs in both adults and children compared to placebo. The proposed mechanisms include passive transfer of immunoglobulins (especially IgG), enhancement of mucosal immunity, and modulation of the gut microbiome, which can indirectly benefit systemic immune function. While results are promising, the number of high-quality studies is still limited, and there is heterogeneity in product formulations and dosing, which complicates broad recommendations. Traditional use of colostrum for general health and infection prevention is also documented in various cultures, but the more robust support comes from recent scientific studies. Overall, evidence suggests that colostrum may help reduce the risk and duration of colds, but it should be seen as a complementary approach rather than a primary treatment.
