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.

Vinpocetine 10 mg

Posted by Reviewer1615669 on Jul 09, 2010

I am on my 2nd order and for the past 6 weeks I have been taking 3 tablets a day. So far I can see no results. I will finish out this order and unless there is improvement I will not be reordering.

after taking for 2 weeks, see no improvement whatsoever these were bought for us by a relative who was hoping it would help the alheimers disease, but it does not, sadly. may work for those whose memory is slipping due to normal aging process.

Terrible Reaction!

Posted by Reviewer2307348 on Nov 03, 2008

I had heard these help focus and concentration, so I thought I'd try them to help with CFS induced brain fog. Boy was that a mistake. I had the worst reaction to the stuff! After about an hour, I started feeling kinda spacey. Then a while later, paranoid feelings set in, so I laid down for a while. Trying to rest, depressing thoughts raced through my mind causing me to weep uncontrollably, finally I fell asleep... very strange and out of character for me!!! Woke up the next moring and was back to normal. First thing I did was to throw these things in the trash!!! This was an extremely unpleasant and scary experience for me. I am sensitive to many chemicals, but this is the first natural supplement I have reacted negatively too. Just thought I'd share my experience for the benefit of others who may react similarly.

Taken as directed, this was one of the first "non-drug" supplements I put my mother on and she showed tremendous signs of improvement

Works well. Use it in combination with your other favs. Adds noticably to mental sharpness and clarity. Has long been on my good list.
