Great Product

Posted by Reviewer2154484 on Oct 24, 2007

i ordered the Prevagen for my husband who has hand tremors.He was questionable about taking it so i told him we both would take it for a week and see how it helped us. I noticed while eating breakfast his hands weren't shaking.I mentioned it to him and he said probably the Prevagen is working.Maybe we should get some more and try it a little longer if it isn't to costly. So I'm going to order our second bottle. For me I seemed to not get as tired and selpt better.

I've yet to recommend this product to anyone who did not profit thereby. It has helped folks with Alzheimer's, dementia, and generally memory retention.

it is not a miracle, but really improves mental alertness and memory, the only problem is its price.

It's hard to tell if your brain is working better or not, but if I had to say one way or the other, I think this is working. Seems my brain is not a fog, I remember better, maybe even think quicker.

It Works!

I use this along with Alpha GPC and Bio-Genesis CogniFactors. It has made a big improvement in cognitive function and memory.

Most important

This is by far the most helpful of all my supplements and I love the side effect.... deep sleep. Helps me get out of circular thinking... where you don't get anywhere.I don't forget things in the middle of the sentence!

Purchased for Alzheimers

Posted by Reviewer1425160 on Jan 24, 2014

My wife's ability to function has been deteriotating steadily for over 3 years. It took about a week for Prevagen to kick in, and I've noticed a definite improvement. I don't know if this is reversing her Alzheimer's, but it certainly is helping with daily activities. I coupled this product with Amyloban-3399 and created dynamite. Her formerly bad mood (a known problem with dementia patients) is now better than before she showed symptoms.

My wife has been having a bit of memory loss and she has not been on the prevagen long but says it is helping.
