My doctor recommended taking NAC when I got my flu shot, to ensure I was purging the metals present in the vaccine (I had just finished chelation treatment for metal toxicity, so I was particularly sensitive to exposure). Works great!

Not sure if I am suppose to feel a difference taking these but my fmd recommended them and I dont feel any worse! Only 3 stars due to the taste and tablet form isn't as easy to swallow.
