SCS - What does "no-added dairy" mean?

The probiotic states "no added dairy" bc it is very common for probiotics to use fermented dairy products to harvest their bacterias and we wanted to ensure that ours does not use dairy or add extra dairy/probiotic into our product. Due to the use of bifidobacterium, the product may contain small amounts of colostrum (pre-milk). but this isn't considered dairy bc it doesnt have the lactase (what lactose intolerant people react to), full bodied fats and nutrients like ordinary milk, but is is full of immunobeneficial nutrients (so it does vary)."
