keep in mind that there are two forms of dairy intolerance. lactose gets the most press, but there is another protein called casein that can be as bad or worse. worse not just in effects, but it's apparently acceptable for products containing casein to list themselves as "dairy free."

either way, looking for lactose-free dairy products is akin to looking for tomato-free ketchup. you are better off looking for soy or rice based alternatives. spend some time at whole foods or similar markets that carry lots of organics - they have the best selection and will give you a good road map for your options.
