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.

This seems more effective than the normal NAC, but it's hard to tell. I don't like that it contains polyacrylite - not healthy at all - but perhaps that is made up for in this product being more effective for detoxing overall.

I've PND (Post nasal drip) and N-A-C helps with dissolving excessive phlegm. I have been taking DR's Best NAC for the past few months and decided to give Jarrow's Formula a try, since it's sustained-released, I thought it would provide relief throughout the day. Jarrow's Formula has other products that were effective, however this did not work for me. I am going back to Dr's Best for NAC.

it can be hassle to eat this pill..it works better with some orange juice. the pill itself is very sour.

I havent been using this consistently yet, so I do not notice any difference at this time. The bottle indicates to take, preferably, on an empty stomach. I take other meds first thing in the a.m. that cannot be taken at the same time as this, so I guess I will need to take it at night.

I don't see any difference, but heard NAC is good for health.
