No: Lactose is milk sugar. Lactose intolerance is when someone does not have enough lactase enzyme, the enzyme specific to digesting lactase. Lactose intolerance is very common. Caseine is milk protein. Lactase enzyme is not involved in digesting milk protein. Someone who is lactose intolerant can usually tolerate caseine if its in a lactose free food or if they take lactase (brand lactaid).
