Posted by Reviewer1199452 on Apr 03, 2016

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

Posted by 4921755032416989121 on Feb 19, 2016

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.

Improved my mood and memory

Posted by ALoren on Sep 28, 2013

I just started taking this less than 3 weeks ago, but I can feel that my mood+awareness has improved (my mind is more awake--I am more sociable---and also calmer). I can also feel a slight improvement in memory. This supports the information I have read about PS. I expect more improvement (especially in memory) as I continue taking this.

Not as I thought it would be

Posted by Reviewer1310225 on Feb 29, 2012

I bought this product thinking that I would get the same effect I got from Source Naturals PS. But it was not the case, it is true that it is cheaper, does not upset my stomach like Source Naturals PS did, but it is less effective. I found sometime back that controlling my cortisol levels makes a huge difference when it comes to controlling my ADHD combined type symptomps. With PS this is done easily, but I can now sadly admit that not all PS are created equal. So many of Jarrow formoulas' products are great but when it comes to PS Source Naturals wins hands down when it comes to controlling Cortisol.
