Seems to work!
"I took this for one month and while it may be some time before I see many of the benefits, I have been feeling more focused and alert, much improved from the brain fog due to menopause that I had been experiencing. Also, while it seemed everyone around me has been sick from the flu or some other virus, including family members in my home, I have not been sick since taking these. So far I can see the mental benefits as well as a stronger immune system. I intend to keep taking NAC and will hopefully see and feel more health benefits."
