There are actually many other things that could be helpful, those are what I'd call the top ones. Glutathione, for instance, is a by product of NAC metabolism. Personally, I like blackseed oil and turmeric with bioperine for inflammatory symptoms like joint pain or irritated nose.

Melatonin was also an item in one of the combos. I was given 8 units of blood after bleeding ulcers so I took the NAC & Melatonin immediately but wasn't sure how much stuff my stomach could tolerate. I then added the Ivermectin a couple weeks later.
