I have a big box full of recently bought vitamins. One
day we sat around while I opened up the bottles to check
them out. I passed the bottles around and different people
smelled the contents, each person had a different impression. One person didn't smell anything, another
thought it was foul, etc. Basically, there was nothing in
common between everyone's experience, lol ...
I'd just get a few friends to smell it to see if the ruling is consistent.
BTW, that NAC worked great for my friend's lung coughing
fits in the morning, little mucus in the lungs.
