IGF-I, IgA, And IgG Responses To Bovine Colostrum Supplementation During Training

Effect None
Trial Design Double blind
Trial Length 2-4 Weeks
Number of Subjects 30
Sex Both Genders
Age Range 18-29
Body Types Average
Notes for this study:
Supplementation of 20g colostrum (4.8g immunoglobulins and 74mcg IGF-1) for two weeks in healthy adults is able to increase IGF-1 concentrations by 17%, but this does not appear to be related to oral consumption of IGF-1 in the product (as it is hydrolyzed).

Salivary, but not serum, IgA was increased 33% and IgG was not affected despite oral ingestion of 4.5g IgG (0.3g IgA).
