I love this product and initially felt really good taking it the first week. I've been taking this for 2 weeks. Began using this to detox from removal of amalgam (mercury/silver) dental fillings. Without knowing the cause, I started to feel anxious, constricted...like I had too many things going on at once. I then had a dental appt. and they took my blood pressure before placing a crown. They said my blood pressure is high, which they thought would be nervousness sitting in a dental chair. Never had high blood pressure before...am 40 yrs and healthy. I later found on the Internet that research from the University of Virginia Health System has found that NAC can cause the body to believe that it is experiencing hypoxia by forming a molecule that causes the signals the blood vessels they are low on oxygen. The body responds by increasing pulmonary blood pressure, which then causes the heart to swell. Due to the possible effects on blood pressure, patients managing their blood pressure should consult with their physician before taking N-Acetyl-L-Cysteine. I have now switched to L-Glutathione to detox from mercury and other toxins.

I take this to keep my liver healthier and to aid detoxification. I also take it as it is said to kill some pathogens and infections in the blood such as the elementary bodies and spores of cpn - chlamydia pneumoniae bacteria - which I have in my blood, one of the causes/consequences of my m.e., and helps keep it cleaner.

Antioxidant NAC is a good product. In Finland this product has risen up discussion many times. This will help lung function. I'm pleased!

Good too for after drinking/hangovers. I usually take one right before bed or first thing in the morning.

I like wine and if I have a couple of glasses I always take one or two tablets before I go to bed. Works like a charm. I wake up with no fuzziness.

I've had a greater sense of well being sense using this form of NAC, which suggests I was low in the antioxidant glutathione. Jarrow makes great products.

Some great health benefits of NAC have been established by clinical trials but I take this to help reduce hair loss due to low thyroid function -- a friend claims his hair is much fuller and curlier with this product. Subjectively, I feel it is helping. Plus, my hair cutter said "Your hair is thicker!" when I went in a few days ago. (She knew nothing of my supplement efforts, her reaction was a truly spontaneous comment.) I also take extra biotin and either Ayurveda bhringaraj herb or TCM foti plus Pure Synergy "Bone Renewal." All of these benefit nails, teeth, hair and bones. The only reason I cannot give this product five stars is because it contains magnesium stearate, as most of the Jarrow line still does since they have not yet altered their factories to remove it from the process. This is especially unfortunate for a liver-detox support product. N.A.C. as precursor to the super antioxidant. Internet claims: "It may aid in the prevention of heart disease, boost the immune system, improve metabolism and promote hair growth. " Many people with lung and breathing issues respond well to it because it has been clinically proven to thin mucous and open breathing passages so it is sometimes prescribed physicians for this purpose. ++ c j

Having taken NAC since November of 2009, I was more than pleased to find it here on IHerb for 45% less. NAC, Jarrow Formula, which is the best brand, is the only 'medication' for my IPF.

I believe that this supplement is very good to help cure a leaky gut. I trust in Jarrow. I think it's a good brand. I take one a day, like it says on the bottle. I take it before I eat (20 to 30 minutes before), because I think it will work better that way.
