Is chewable type of Prevagen better or the capsule?
A shopper on Sep 5, 2016
BEST ANSWER: I've always bought the capsules... I didn't even know that it came in a chewable... My opinion is you can take a capsule or a chewable, and they'll both work the same... Maybe if anything, the chewable will absorb quicker then the capsule, but other then that it will have the same effect... Good Luck!
