I Can Sleep

this has really helped me be able to sleep, it lowers my coritsol in the evening and it really does bring mental clarity. it is expensive, but as usual IHerb is the most reasonable place to get it.

I take 600mg a day to reduce cortisol. I have noticed that I am more focused and creative. I am slowly losing belly fat as well
This Phosphatidyl-Serine is great for memory - perhaps a little too much!

Improved memory - and better sleep
Posted by Reviewer1431253 on Nov 20, 2009
I switched to PS-100 at the suggestion of the local herbologist when I said I had some concerns about continuing to take Gingko Biloba. I wanted something with the same effect on memory, but perhaps not the effect on blood pressure (that I had heard could be an issue). I have been taking PS-100 for about 3 months now and get the same type of mental clarity I got from GB, and as an added side effect am sleeping wonderfully! I didn't know that was a claim of PS-100, and realized I was sleeping better before I ever read that was a claim.

These are wonderful. I take 2 a day for my memory. My husband can tell if I forget to take them. I strongly recommend these for anyone who is having trouble with their memory.

This product really works. Your memory will improve if you take it each day. When I don't take it, I have a harder time recalling details, names of people, and overall getting my clarity of though in order. Excellent product and it goes down easy.

This stuff cuts my nighttime cortisol so I can sleep. Also makes it easier to wake up in the morning. I've tried everything else but most negatively affected my hypothyroidism.
