Excellent Product

Posted by Googsta on Jun 08, 2012

I decided to supplement with NAC to help my body produce glutathione. I have ME/CFS & suffer alot with insomnia & excitoxicity. I've tried many products with no effect but I found this product really helped my sleep, I even had a routine for the first time in years! I took one tablet in the early afternoon & a second one early evening, I was then ready for bed by around 11pm. Worth a try!

PCOS support

Posted by Reviewer3334884 on Mar 24, 2014

I'm using this after reading reports that NAC is just as effective as Metformin in treating PCOS. Seems to be helping. It's hard to tell when using multiple supplements, but I started this a few weeks after my other supplements and it seems to have improved my insulin sensitivity.
