Increased energy
1 people found this helpful
I have Chronic Fatigue Syndrome, and I’ve found that taking NAC twice a day gives me more energy. Each capsule seems to provide a boost for about six hours, after which I start feeling fatigued again if I don’t take another. I would recommend that anyone with Chronic Fatigue Syndrome try NAC.

Improved sleep
NAC is reputed to be a precursor of glutathione, and I began taking it for its detoxifying effects on the liver and antioxidant benefits. I noticed my skin became less dull and blemishes diminished after a month. I had to stop due to stomach pains but resumed a couple of days ago, having struggled with fatigue and sleep issues. To my surprise, the effects on my fatigue from Chronic Fatigue Syndrome were noticeable from day one, and I have been able to sleep soundly since starting it again.

I am recovering from an iron and copper deficiency that went undiagnosed for quite some time. After building my stores of these nutrients, NAC gave me an energy boost as well. I believe it is healing my cells from the years of stress associated with insufficient copper and iron. I highly recommend it for anyone as research shows many benefits of NAC.

Exorcism! It is well packaged, and the quality is good. It has a peculiar smell, but it does not bother me much. It helps with immunity and is effective in alleviating fatigue.
