Works great for sleeping thru the night

Posted by iHerb Customer on September 8 2009 | Verified Purchase

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!

Thanks for your feedback!

Very good

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

Thanks for your feedback!

I feel semi-intelligent again!

Posted by iHerb Customer on August 4 2009 | Verified Purchase

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!

Thanks for your feedback!

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 iHerb Customer on March 21 2010 | Verified Purchase

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.

Thanks for your feedback!

Helps Recall

Posted by iHerb Customer on October 12 2013 | Verified Purchase

I have consistently taken this product for several years and sincerely believe that it helps my mental sharpness and recall ability. In fact, recently I ran out and noticed my recall was not as good as normal. When I started taking the product again, my mental acuity shot back up. This is a good product. I take 2 pills a day separated by a couple of hours in the morning (e.g., one with breakfast and then a couple of hours later). As a side note, i also take Pycnogenol which also seems helpful for mental sharpness.

Thanks for your feedback!

Good stuff!

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

Thanks for your feedback!

True 100mg

Posted by iHerb Customer on March 18 2009 | Verified Purchase

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!

Thanks for your feedback!

Great for brain function

Posted by iHerb Customer on May 6 2010 | Verified Purchase

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.

Thanks for your feedback!
