この研究の注釈：
Supplementation of 10g bovine colostrum (20% Immunoglobulin G) failed to influence neutrophil adhesion factors (CD89) or surface markers on NK cells or lymphocytes. The expected decrease in CD3+CD8+ T cells seen with exercise, however, was attenuated relative to whey protein control resulting in a lesser reduction in the CD4/CD8 ratio associated with intense exercise.

The increase seen in salivary IgA with colostrum failed to reach statistical significance; total IgA and IgE in serum were unaffected. Overall rates of sickness trended to be reduced, but this did not reach significance.

Bovine colostrum (low-molecular weight fraction at 150mg in capsules) in otherwise healthy adults noted that supplementation was able to acutely increase phagocytic activity of monocytes. Total T cell count was nonsignificantly modified after one hour which normalized after two hours, and NK cells appeared to be decreased at one hour only to be normalized within two hours.

All effects noted in this study were transient, although the study only lasted for one day in length.
