I called QNL and asked if their colostrum had any casein in it. The girl said she wasn't sure, went and asked someone else, then came back and said it had no lactose in it. Then I asked if it had any protein in it and she said yes it does have "some protein." There are many diff. kinds of protein so the question is, what %, if any, casein... and might a non-casein protein, that is structurally similar, also be bad... ??
