Review: I have had problems with ephasia since I suffered a brain hemorrhage in 2016 and decided to give this a try. I was just hoping to stop or slow any further decline, but my friends and family have told me that my speech and focus have been markedly better over the last few weeks. No one knows that I have been trying this and it is the only new variable in my day to day life. This is the first time I have felt optimistic in a long time and that means the world to me.

*by K***E on 2 March 2020*

I've purchased this product several times because I trust Peak Performance to leave the junk ingredients out. L-Serine is calming and helps me sleep well. I discovered it when looking for help with ALS. I'm not sure that it's helped, but I haven't noticed a decline in my symptoms in almost a year. I take a few other supplements too, but this one is at the top of my importance list, along with magnesium. Now if Peak Performance could bring the price down on their Magnesium. I'd love to try it too.
