<<Disclaimer: Verify this information before applying it to your situation.>> I don't want to fan the flames of the 'gluten in milk' controversy because I know nothing about it, although I highly doubt that the vitamins added to milk would contain gluten. However, I do remember my daughter's allergist telling me that her wheat 'allergy' might become aggravated during the summer months when milk cows were grass grazing. Does anyone have any information about that one? BJ
