Amazing lung-strengthener! (I'm not a doctor)

I started taking NAC on the advice of a doctor in our family because coughs tend to linger when I get sick and its hard for me to get rid of them. Since starting daily NAC I have had no regular colds or flu, but did catch COVID and recovered pretty quickly. I live in a high-allergen area and it seems to help with those too.

NAC - Good for the LIVER !

Take a NAC every day.... This is a large pill - some people may find this a little difficult to swallow.
