I am really not sure why news organizations all around the world feel the need to debunk Vitamin C usage for novel coronavirus. For instance: https://www.snopes.com/news/2020/03/09/coronavirus-its-time-... . Their conclusions all amount to: washing hands is better, you may get a tummy ache, and don't believe folk remedies.

Vitamin C is essential.

This means it is essential for tissue repair. Also the production of neurotransmitters / cell signalling molecules.

Of course it improves recovery and reduces severity of symptoms. Of course it won't prevent anything.

I can't understand how there is any dispute.

Also the word VITAmine gives it away, doesnt it :)

That is the idea.

A lot of people are magnesium deficient too. Magnesium is known essential in over 300 enzyme pathways.

> Of course it won't prevent anything.

You are full of nonsence. Of course it prevents scurvy ffs.

> This means it is essential for tissue repair.

This totally doesn't mean that. Vitamin C is cofactor and resource. It is used in bunch of processes, only some of it are for repair.

Ah, sorry, yes, that's true. I didn't mean Vitamin C doesn't prevent Vitamin C deficiency.

Your second statement doesn't negate my claim that Vitamin C is essential for tissue repair. It absolutely is, but of course that's not all it's essential for, and I did hint at this in the bit you didn't quote.

https://www.xkcd.com/882/ There are issues with significance. Everyone loves testing Vitamin C as a cure for X. Wake me up when follow-up studies from another group show an effect.
