I wondered the same thing about 10 years ago when I started taking ADEKs.
My doctor said it DOES NOT MATTER if you dont chew them, and just swallow them.
I hope he's right, cuz I've been just swallowing them for the last 10 years...
seriously, I can't imagine it would make any difference, either way the stomach breaks it all down to be absorbed in the duodenum, RIGHT???
