Works great for sleeping thru the night
Posted by Reviewer1204429 on Sep 08, 2009
I used to wake up at 3 a.m. every night to a racing heart and anxiety. That does not happen anymore because of this great supplement. I sleep thru the night and my anxiety is gone. I take 300mg's before bedtime. When my anxiety is severe, it takes 500mg's before bed. LOVE LOVE what this does for me!

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
I feel semi-intelligent again!

Surprisingly, I actually believe I am remembering better. I have tried many other memory products; this one really seems to help. I have a job where I am juggling ~ 100 things at one time trying to sort them, trying to remember which item must come first. I still use lists, but now I remember why I placed something on the list. I haven’t had the “OMG, I totally forgot what the heck is this” feeling in the past couple weeks. Amazing!

I've been taking Dr's Best Phosphatidyl serine for a couple of weeks now and have found a marked improvemnet with mental fatigue and enhanced recall. If you want to strengthen your mental capacity I suggest you start taking this wonderful nutrient.

This product kept me awake
Posted by Reviewer2866276 on Mar 21, 2010
For more than a month I couldn't get to sleep and when I awoke I couldn't get back to sleep. It finally dawned on me this was the culprit. The Phosphatidylserine was NOT the problem. I believe it was the Medium Chain Triglycerides (MCT). I got another product with phostidykserine instead. I eat very cleanly, no caffeine, no MSG no sulfites or nitrates so it bothered both my husband and I maybe more than most. I would NEVER buy this again. PS. Iherb is wonderful.
Great for brain function

Underrated supplement. Helps form the cell membrane, specifically of the brain/nervous system. These are rapidly destroyed with mercury poisoning. My cognitive function improves when I take 2-3 a day.

I have noticed a heightened cognitive ability since I recently began taking phosphatidly serine. I recommend trying it.

Great quality at a great price. Beware of other products that claim 100mg per cap!! Some include other ingredients to get this dose and actually contain merely a fraction of Phosphatidylserine. This is 100mg PS per gelcap!
