Makes me a bit sleepy/tired

Posted by Reviewer2158986 on Sep 18, 2014

I took this before bed a couple of times, and couldn't get to sleep for hours, even though it makes me feel tired. There is a relaxing feeling that comes over my body after taking this tablet (not a placebo effect). I'm trying the natural factors brand tomorrow because it's sunflower and the inositol content appears to be lower. I suspect (and hope) it's the inositol content in this is whats making me feel tired. I've noticed I'm very sensitive to medications and natural supplements.

Calms down cortisol, enhances memory

Posted by Reviewer1159045 on Aug 29, 2013

Excellent product. I use it to keep my cortisol levels down, but I've also noticed my memory is much better than my husband's (same age). I started him on it a few weeks ago - maybe he'll remember where he puts stuff away!

Best PS

Posted by Reviewer1055106 on May 19, 2013

I have tried many brands, but this one seems superior. I notice such an increase in memory which I have not experienced with other brands. I combine this supplement with "better brain" from "new chapter", also found on this website. PS helps the omega fatty acids penetrate the cell membranes. That is why the combination omega 3 and PS is so important for better brain healht. PS is found in the omega 3 supplement "better brain", but I need extra PS to lift my brain fog and be able to focus on mental tasks.
