it really works!

Posted by Reviewer3231842 on Apr 06, 2009

One of the very few supplements that actually has a noticeable effect (it is even proven by studies). I come up with good ideas at work meetings and think on my feet well all day. This is a must have if your job requires lots of thought, decision-making, and/or creativity. Affordable too! And the tablets are small and easy to swallow. An all around win.

Good product

Posted by Reviewer1300695 on Apr 16, 2009

It arrived (to Canada) in 2 weeks. I also take Huperzine at the same time as I read the two work well together. It's only been a week, but so far it seems to be OK. Slightly better focus and more clear headed.

Everyone should be taking this product and it's so cheap!

Absolutely excellent product and great value! Everyone should be taking vinpocetine. Undoubtedly helps cognition, blood flow and reputedly eyesight.

5mg=too little. 15mg=too much. 10mg=perfect. It is one of those few reliable substances that don´t let you down as a potent energy booster and a mid nootropic. Remenber to take it with food.

Since I've got into law school, I've been searching for "wonder drug" for studying because I do not like law so so much :) I've tried rhodiola that gave me pretty good results, but I've had "unwanted effect" with it (it boosts male libido too much, and I'm in my 20's so you'we got the "bigger picture") After that I've bought 2 bottles of Jarrow's Neuro Optimizer and I was so disappointed with it (read my review). VINPOCETINE/HUPERZINE A was my last shot; my last resort; my last everything of getting a little bit "sharper" studying skills. Since they are both some kind of inhibitors/blockers, I've started from small dosage (half a tablet of both daily). It cleared my mind, it gave me sharpness and "will to study". My mind is clear like in the day of exam (students will know) JUST ONE MORE TIME!!! ESTIMATE YOUR OPTIMAL DOSAGE, IT CAN BE DIVIDED, OR IT CAN BE FULL (LIKE ON THE LABEL)! ALL THE BEST.

Mental performance & concentration booster!

Posted by iHerbalicious on Nov 30, 2012

I have ordered this for my boyfriend who is currently in a process of finishing up his Ph.D. and has quite a hectic schedule. He said that since starting taking Vinpocetine he feels he is being more effective and his concentration level has improved.

Memory Helper

Posted by 4685375285003645141 on Jun 21, 2013

I use this supplement for my memory. But make sure you're not low in iron (like I was!) or all the other herbs/supplements in the world aren't going to help. It does seem to help with my memory.
