Hi Haze -
I'm not a big fan of whey as many people are sensitive to it as they are to dairy - even if it is "lactose-free."
As with many foods, there is a big debate as to whether it is an alkalizing food or acid - with people on both sides of the fence.
I think ultimately it is wise to see whether or not it agrees with your system. And also to consider why you want to incorporate it into your diet.
I know that "protein shakes," etc. are very popular -- but I think there are so many better choices. A "green food" drink would be a better choice in my opinion with some quality green food supplements. Unless you are trying to use it as a meal replacement, in which case I would recommend Ultimate Meal instead. There is another product that is similar to Ult Meal that is cheaper too (forgot the name) that would also be good.
