Sorry for the delay in answering your question. I had to wait for a response from the colostrum manufacturer. In the USA the primary milk is from A1 cows with some A2 variants coming on line in specific regions. So, this colostrum is a combination of A1 and A2, primarily A1. The beta casein, with which you are most likely concerned, is in smaller proportions in colostrum than that in milk, as the transformation to milk begins around 24 hours after the birth of the calf. In addition, the peptides in colostrum temper allergic reactions by regulating the production of TH2 cytokines, and thus preventing the production of IgG antibodies from the casein. This means that if there are concerns with inflammation or milk allergies these concerns will likely be less with colostrum. This is even more likely when the serving size is taken into account as a much smaller serving of colostrum is used than one would consume with milk.
