Very effective, especially for the elderly Parkinson patients and with the brain crowd. Suggest your company to mass production.
I feel very effective, my memory is poor. After taking the feeling of memory has greatly improved, the reaction is also faster.

Good but expensive
Me (40yrs) and my parents (85yrs) are taking it for about three months, once every week. The effects on memory and physical coordination improvements are more evident in my parents. I would like to take it more often but it is quite expensive and it is not available for shipping to Mexico.

I've been using "GNC Phosphatidyl Serine 300 MG"
For a little over a year.I'm on a disability for short term memory lose. My Dr. in arizona said he could help me with my memory lose by taking one small pill at night when i go to bed. I feel like i have come almost back to normal. My wife and friends are amazed. This is the best pill i have ever taken to treat my memory. I am doing just about everything i did before. Even bought a new motorcycle.

Is this serine product derived from soy? I know the 100 mg one is,but this product doesn't list soy.I know some serine products come from egg,or sunflower.
