Except vitamin D: zinc+ionophores (quercetin or EGCG or HCQ) slows the virus growth and should also be taken prophylactically, and C and NAC help when there is an acute infection. MedCram has videos about this with links to that science.

"Evidence that Vitamin D Supplementation Could Reduce Risk of Influenza and COVID-19 Infections and Deaths "
(3 of June 2020) A very good list of the best Vitamin D studies:

(22nd of May) I and Dr John Campbell both just learnt from Dr Shelton that if you clean your skin with soap after the sunbathing, then you will become Vitamin D deficient even if you are an old person out in the Florida sun every day.
And mammals lick their fur to get vitamin D, while birds have an organ on their back so that they "lick" their feathers in a different way.

Irish researchers demands Vitamin-D supplementation advise from the government: https://scitechdaily.com/vitamin-d-determines-severity-in-covid-19-researchers-urge-government-to-change-advice/
If everyone eats 50-125 µg (2000-5000 IU) vitamin D (+K2?) per day, SARS-CoV-2 is harmless (especially if you also take zink and a zink-transporter like quercetin/hydroxichloroquine/NAC. Star anise seems to be helpful too. These explain India's few covid-deaths despite rampant vitamin D deficiency. See this paper: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6060930/ Everything else, even French smokers' lower risk of infection, can be explain by vitamin D deficiency. ):
Everyone under 75 years with severe case of covid had a Vitamin D deficiency:

This paper shows that Vitamin-D deficiency is the cause of COVID-deaths, not only a correlation:

People with low Vitamin D levels are easier infected:

Compensated for age and comorbidities, there is still a 10 times higher risk for severe covid with Vitamin D deficiency (note that many of the comorbidites are caused by vitamin D deficiencies though!)

FDA have ordered SSRN to delete the Indonesian #VitaminD human study from the database - shocking when scientific studies now censored also

"The benefits of vitamin D supplementation were even more noticeable in children who had low levels of vitamin D at the start of the study, with a 74 per cent reduction in the incidence of ‘flu observed. "

The Vitamin D deficiency has exploded in USA. Ivor Cummings explains here:

While Finland has greatly improved their vitamin D levels the last decade:

"I Finland har man haft en politisk strategi för att förbättra D-vitaminstatus hos befolkningen. Bland annat rekommenderas tillskott till alla, från födseln och upp till 18 års ålder, och man har sedan många år tillbaka berikat livsmedel i större utsträckning än i övriga nordiska länder."
If vitamin D deficiency is eradicated, 70% of Big Pharma will be wiped out, and their ads in media and donations to MDs...
But even vaccines need vitamin D to work:
