The one I take states that it "contains traces of milk and soy". Traces indicates to me that the amount would be so minimal that it should not bother you. I do suspect that I am lactose intolerant but I've not had any problems with it. Also, it does contain something that is supposed to help people with lactose intolerance - I don't remember what it is exactly, but I read something about it. http://www.iherb.com/ProductDetails.aspx?c=1&pid=3705630389853301316&at=0
