Jarrow PS-100 was recommended to me several years ago by a friend with a PHD in biochemsitry who owns a vitamin store in Long Beach, Ca. It works.
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.

This is my first time using it and I have seen results in less than a week. Careful with the dosing/timing, each person is different and the body reacts differently, I take it in the evening, 1 capsule a day.
I can't say I feel anything

I can't say I feel any stress reduction or improvement of sleep. This is my 2nd bottle. Expensive for what it does...

I think that this Phosphatidylserine does not contain soy or bad allergens. No stomach pain no nausea. I thought it would make me more alert so I took one in the morning and one after lunch, after two day I could hardly keep my eyes open and reading was a chore. It over relaxed my body. I could not function. So I stopped and sleepiness/drowsiness stopped. I don't see how this is to keep cognitive functions alert and clear, I think maybe it works best taken after dinner when you want to unwind. Everyone is different. I think I will not rush to buy again as a protein shake at night helps me sleep well. I will however keep this on my list to order if I suffer at anytime form insomnia it would be worth trying then Ha! IHerb provides good customer service and fast DHL delivery Thank you!
Doesn't work for me

I bought this because I'd read a number of articles about how it lowers cortisol, and that was my objective. However, I have since found scientific research that shows that its cortisol lowering ability is very minimal and is overstated by many websites looking to sell it. I didn't notice any change when taking this other than having more trouble getting to sleep than usual, and was also hoping that by lowering cortisol levels PS would help me get to sleep and stay asleep. Off to try something else.
