Amazing stuff for reducing stress and cognitive functions

14 people found the following review helpful

Posted by Reviewer1075408 on Oct 27, 2009

While this product doesn't get a lot of attention I think it's a very important supplement. It seems to take a few weeks to get the full effect, but it's helped me to: think clearer, be more relaxed, my body just seems to be under less stress altogether. This also has properties that blunt cortisol and I'm noticing that all my other hormones are working better since cortisol has been reduced. I can almost stop taking my thyroid meds.

I am used to getting up 3 to 5 times a night to use the bathroom. This keeps me asleep till about 5 in the morning. It works much better for me than melatonin.

I take 4 pills of PS after a heavy workout - it is supposed to control cortisol and I can definitely tell the difference if I don't take it (I'm more agitated and sore without it). I've used Jarrow PS for years - it's always high quality and usually the best price.
