The dairy is used to culture the lactobacillus microbes. Most of it is metabolized by the bacteria in their growth and the remaining dairy is very small. I think that the benefits of this probiotic far outweighs the tiny risk of miniscule amounts of dairy. When I warned about yogurt and kefir, that is because they are mostly dairy (ounces of dairy) whereas this probiotic you mention is perhaps milligrams of dairy. I don't think it is a big deal myself.
