Be careful - Too Strong Effect

Posted by iHerb Customer on June 2 2011 | Verified Purchase

The effect of this product is really too strong. As doctors recommend you have to start with 2mg dosage. So just take 1/5 of a pill. After you take it seems your blood pressure go to zero ... I wish producers will make a 2mg dosage in the future.

Thanks for your feedback!

Didn't help with tinitus.

Posted by iHerb Customer on May 24 2010 | Verified Purchase

This didn't seem to help with tinnitus as I had hoped from many of the reviews here. It must have heightened my cognitive powers, because I noticed a marked difficulty for a while after stopping it, concentrating on reading. I will try this again at a latter date with only half a capsule and see what happens. As always excellent iHerb service and a competitive price.

Thanks for your feedback!

Vinpocetine seems to be working; I am able to think more clearly. Although I disagree with the people who say this site has "great prices." After ordering, I found the exact same supplement for $5.00 less at allstarhealth

Headache Inducing

Posted by BelieveJesus4EternalLife on June 20 2011 | Verified Purchase

Like many people, this absolutely gives me a headache. I would rather be without the nagging pain than to have the slight brain boost this provides. Now I'll tell you what really works as a brain booster and that is Phosphatidyl Serine, 200 mg per day softgel form. As for this Vinpocetine, I'm simply not going to take anymore of it. Plus it seems to give me other adverse psychological effects such as paranoia.

Thanks for your feedback!

No help with my tinnitus

Posted by iHerb Customer on July 25 2012 | Verified Purchase

I bought this to see if it would help with my tinnitus. I took two pills per day every day until the bottle was empty. I took it with ginkgo biloba as I read it can also help with tinnitus. I saw zero improvement. If you're thinking of buying this for tinnitus it's worth a try since it's cheap, but I wouldn't be too optimistic.

Any benefits of this product may never become obvious to me because I am not able to sense anything indicating an improvement in my physical condition. However, in conjunction with other supplements, I'm seeing a better quality of life than many of my peers. So it may be working; and I will continue to use it based on research indicating that it is beneficial.

Just got it and haven't noticed any significant effect yet. I think my hands have gotten slightly colder though..

Thanks for your feedback!

Works subtle..

Posted by iHerb Customer on February 9 2012 | Verified Purchase

I was suprized when I stopped this product for about a week how sluggish I felt. It's too soon to tell wether I will buy this product again.

Thanks for your feedback!

Too subtle to notice

Posted by iHerb Customer on February 19 2012 | Verified Purchase

I haven't used this for too long but on the day upon taking one or two tablets any enhanced cognitive functions were hard to observe, I felt at most perhaps slight perception augmentation
