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!
