Only PS that works for me
I have read many of the positive things that have been written over the years about PS, so I tried a few different brands. None of them worked for me and I eventually quit trying. Then I came across an article that stated the only type of PS that was used in the successful studies was the Leci-PS. There are many different PS's being marketed, few of them are Leci-PS. So I ran a search and found this PS by Source Naturals which really is Leci-PS. I had very good results after a week or two of use (3 times /day). Some can get by with 1 / day, not me. After the initial week or two of use, I can tell an enormous difference with more focus and concentration - a "mental energy" to be able to sit down, relax and read a book. This is something many people take for granted and think nothing of. For me, I had trouble doing this. There is a calming effect which sounds like a contradiction to "mental energy" but it's true. And I can sleep much better at night while taking this product. It is a little expensive but I am willing to pay the price for the great results I am getting.

PS: Save Memory & Sleep Well!!
I am 65 and only take one each morning but faithfully. I was using a now brand with gingko softgel but my memory began to fail so I switched to Source Naturals with Leci-PS and still only take one but my memory is fine again. BONUS: With the addition of INOSITOL, I sleep like a baby. Best to take it in the morning. Lori E of San Leandro CA
