That being said, overall lifestyle of diet is going to be one of the bigger factors.
As far as other things that I feel help - lots of spices/herbs, anything with antibacterial activity, vitamin C, zinc, NAC, elderberry, and I like cats claw although not sure if there’s anything to it on supporting immune function.
I came across this article a while back which goes through some of the research:
TL;DR: The key ones are stuff that helps regulate blood sugar (oxymatrine, berberine, Ecklonia cava - this last one has specifically been shown to inhibit regular coronaviruses).
Vitamin D for sure (I also think that vitamin D from the sun maybe one reason why homeless people seem not to be dying from this). Now it’s sunny outside I think that’s better than supplementing it.
Lastly, I think linked to the stuff on blood sugar, a low carb diet would help immensely. Not just for regulating sugar levels but also lowering inflammation.
Remember that being overweight and diabetes are the two most risky comorbidities, so focus on these areas and I think you’re covering the most important bases.
Lastly, I’d also recommend nicotine gum given smokers seem to do much better with corona.
OMG I TAKE THIS!!!!!Fluoxetin
Scientists at the University of Würzburg have found a new approach to treating Covid-19. According to a new study, a long-established antidepressant significantly inhibits the multiplication of SARS-CoV-2 viruses.
According to the scientists, fluoxetine is particularly suitable for the early treatment of infected patients who belong to one of the known risk groups. However, the actual function of fluoxetine does not seem to be responsible for the effect - the intervention in the serotin reuptake process. This is suggested, among other things, by the fact that other drugs from the SSRI group, such as paroxetine and escitalopram, did not hinder the growth of SARS-CoV-2 in the study. The antiviral effect is therefore not related to the serotonin reuptake receptor. Instead, fluoxetine inhibits protein expression in the virus: it prevents the virus from building the building blocks it needs to replicate in the human cell.
