I have to say, I felt the Huperzine A the first day. Its been about a month now and we are taking both and can't say enough about the benefits. I won't be without it. I take 200 mg daily of the HuperzIne A and use Sage extract liquid daily. I normally take organic powders but after reading about the options I decided to stay with the caplets for now. (You must be real careful with the powders as they are much stronger.) A link to the ones I ordered are at the end of this post.
