I have not tried this product yet but a friend recommended it for ear crystals. She took 3 bottles and has not had problems since with vertigo. I mainly wanted to comment in reference to the person who had a reaction, spacey, weird feelings, crying, sleep. Any product such as this, that opens up blood flow to the brain, may cause reactions like that. If a part of your brain has been deprived of oxygen and all of a sudden it starts getting it again, it may cause you to react in a strange way. That would be a sign to me that it is doing something and I need to keep taking it so that part of my body can return to normal instead of staying impaired. Just because you learn to live with the impairment doesn't mean everything is okay. With anything, unless you have a life-threatening reaction, it is good to give it a couple weeks. Many people say things don't work but that's because they don't give it a chance. Natural remedies work with your body, they don't go in like a bulldozer, so often it takes a little longer to see results but the results are always 100 times better than what you would get from synthetic or chemical treatments.

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.

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.

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

Works for my headaches.

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.

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..

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.

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
