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.

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.

Do not take if you have any type of autonomic disorder.

Four years ago my husband suffered a stroke from undiagnosed high blood pressure and diabetes. After I found this for him he takes it twice a day along with his HNP and diabetes meds and has made a wonderful recovery.

My GP referred me to this product for my severe vertigo. Initially I didn't notice any difference so increased the dose to 4 in morning and 4 of a night and it really did make a difference. My vertigo completely disappeared within a couple of months. I gradually decreased dosage to just 1 of a night and still no vertigo. I stopped completely but my GP recently said it is very good to help with memory and clarity so I've now resumed to 1 morning and 1 night again. I can thoroughly recommend this product for vertigo.

I am using this in combination of Pregnenolone, Huperzine A and L-Tryptophan to help with my memory. I can actually say I have been able to tell that I have better recall since I started taking it.
