I know that we are supposed to use zinc, vitamin C, D3, and quercetin, but has anyone got a suggestion as an alternative for NAC? I found out the hard way that my body does not like it, but want to keep up my immune system.
Also, I haven’t started quercetin but was wondering if there are any drug interactions (my doctor would have no idea)?
Thanks for your help!
Fwiw, I have taken 600mg of NAC for a year with no side effects. I was taking 1800mg for 6 months, with no side effects. This was prior to Covid.
