Size Name:60 Softgels
I have taken phos serine for several months now and it improves my memory and mental clarity. I initially took this product because I liked the idea of the softgels, but it is true that the amount of phos serine in each gel is only 100mg, not 500mg. This amount is minimal at best and to its credit, I still felt it's effects which prompted me to explore further for products with higher dosages available. I recommend 50 Grams (1.77 Oz) Phosphatidyl Serine Bulk Powder. It's pure phos serine powder and contains 5 times the amount for the same price. I take 300mg per day, and have been feeling tip top. I had noticed that I'm not as sharp as I was in my 30's and combined with stress I couldn't remember as well. I think when I run out of these I'm really going to be able to tell the difference, as it's usually in the absence of something that we truly appreciate it's presence.

Should Have Read the Reviews September 15, 2011
By Patty K
Size Name:60 Softgels|Amazon Verified Purchase
I also feel duped- when you purchase something that says 500mg of a product, that's what you expect! It is only 100mg of Phosphatidyl Serine. VERY disappointed!

When the bottle arrived, reading the small print on the back, it turns out that each capsule only contain 100mg (NOT 500mg!) of the active ingredient (Phosphatidylserine). The other 400mg of the "PhosphatidylSerine Matrix" is Soybean Oil and other filler (Glycolipids and Phosphatidylcholine). I feel ripped off! It's not like these are cheap.

Great for cortisol regulation/ sleep
This was recommended to me by my acupuncturist to help regulate my cortisol levels for sleep. As our adrenals wear out, our cortisol gets out of whack and impacts sleep cycles. Read more

Misleading
Each capsule is 500mg, but only 100mg of it is actually phosphatidylserine. This is very disappointing, since it seems to be difficult to find PS in amounts greater than 100mg.
