I've never had asthma before, this formula caused me reaction of tightness in breath-way, I actually was whizzing. It happened 3 times, each about 30 minutes after taking this, so I am pretty sure this formula was causing my "asthma". I did some research for my own clarity. I found out the main ingredient: "N-Acetyl-L-Cysteine" has a side effect for some people, causing bronchospasm, i.e. a bronchial spasm, a sudden constriction of the muscles in the walls of the bronchioles... which is asthma. There are many positive reviews for this product, so only a few had the allergic reaction. Just a word of caution in case you have allergic reaction as me, also be careful if you are giving this to children. I just wonder why they put this "N-Acetyl-L-Cysteine" in it when it is supposed to be taken by people with a weak respiratory condition.

Review of Natural Factors Lung, Bronchial & Sinus Health

Posted by Reviewer2148284 on Jan 24, 2012

This product is excellent if you are coughing, "whistling" in the bronchial pipes, unrestful, so that sleep is disturbed. If you take two tablets, the effect will come within one hour and last for about six hours. You wil cough up some phlegm, and sleep will be much better. You can also take this product for an old bronchitis, that will not really go away. There are many other possibilities....

I have tried for many many years to find something to clear my right sinus! All of the "miracle" remedies that are made JUST FOR THE SINUSES. I've never had any luck - - - - - UNTIL NOW!! I have a tooth embedded in my sinus cavity and my right sinus tends to get infected over and over again. But as long as I take this stuff daily - it helps tremendously!! Yeah - I still have a stopped up nose when I wake up and I have a little facial pain in the sinus area but it's barely even noticeable and it doesn't last long at all. And it really keeps stuff from building up in my sinuses - I can actually blow my nose daily and it keeps that horrible stuff ouf of my sinuses. I will never be without this stuff OR my Clear Lungs!!!!!

Really works

Posted by Reviewer1990789 on Feb 05, 2012

Last year I had a bronchial issue that would stubbornly not go away with all the things I tried. This formula cleared it up in 2 to 3 days. Amazing stuff.
