There are now close to 30 or so studies demonstrating that having optimal blood levels of 25(OH)-vitamin D (75-150 nmol/L) reduces covid-19 risks: reduced risk of infection; reduced risk of severe disease; reduced risk of dying. Many researchers now regard the evidence as ‘overwhelming’. Despite this, there still will be those who say that we need ‘more research’, but in the meantime, there is little to be lost (vitamin D supplements are inexpensive and have low risk of toxicity) and a huge amount to gain by recommending a decent daily dose of vitamin D3 (say 1-2,000 IU for children and 4-5,000 IU for adults).

This is the Spanish study I previously mentioned where some patients were treated with calcifediol, a form of Vitamin D and others weren't

Patients with sufficient levels of vitamin D are less likely to experience complications and die from COVID-19, according to a new study in the US, while another has found it also reduces infection rates.

Vitamin D deficiency may raise risk of getting COVID-19, study finds
Well I've looked back and I still can't find any studies you've linked to. I can only see that you've listed the potential side effects of taking too much vitamin D but that isn't what I asked, I said recommended doses.
