Good stuff

Posted by iHerb Customer on Nov 22, 2014 | Verified Purchase

I have an illness and this stuff helps me to clear toxins and it is kind of like the sulphur in broccoli.. my doc swears by it.. i think this source naturals is a good price for a good quality product... many benefits to this NAC.. iHerb is excellent by the way.. good prices and service - just the return policy needs tweaked - but they are a definite go to for me for many years now on my journey to health and wellness - they have certainly helped me and I am grateful for them.
