N-acetylcysteine (NAC) is a harmless (EDIT: please check at least https://en.wikipedia.org/wiki/Acetylcysteine for possible side effects) compound which protects your liver, you can buy after searching like for 10 seconds
I ve been taking it for a week (1 pill, 600mg per day) before noticing that drinking doesn’t do anything. Went to a party, drank 3 pints of beer, one after another, with absolutely zero effect. Usually, just 1 pint is enough to get socially talkative, 3 pints of beer i am supposed to be very obviously drunk.
Another time, drank a third of a bottle of wine (at my place, so it cannot possibly be watered down), the only effect was nausea (which never happened before), again, zero drunk-ness effect.
Now, depending on people that anti-alcohol protection might be an advantage or drawback. I just found it interesting, so sharing here
Edit: as one comment points out: https://pubmed.ncbi.nlm.nih.gov/30019966/
NAC is amazing and I highly recommend it, especially for long covid problems involving lung capacity.
But NAC does have one potential harmful effect that I am aware of. It is a powerful antioxidant, and too much antioxidant activity has been found to predict lung cancer.
So don’t take a lot of NAC for a long period of time.
I swear by it myself. It has done amazing things for me. But it is a powerful drug (I think it’s a drug and not a supplement because I don’t think it’s a nutrient but I could be wrong)
