I would recommend this product.
I am finding I am more alert and not quite as tired during the day. I have only been taking it regularly for a short while; I am hoping for an improvement in memory.

BEST ANSWER: I feel like I saw results within a couple of weeks. You will see some difference within a few days, but noticeable difference after a couple of weeks
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!
