Does Phytase Really work?

I have heard that the phytic acid in whole grains is “bad” for you because it prevents minerals from being absorbed. Also that you can buy enzyme products that contain Phytase, which would neutralize the phytic acid and therefore allow your whole grain to be properly absorbed & digested.

Someone, somewhere, suggested that “it doesn’t work like that” but didn’t explain himself.

Does anyone here have any further information as to whether or not it does any good to take a phytase supplement?

I have no intentions of removing whole grains completely from my diet, even though I don’t consume a lot of them. I like brown rice once in a while and do not wish to always have to soak it for a day or so in whey. I don’t even have access to whey.
