care to provide some evidence of this?

Yes, no problem.

This letter to the BMJ from a GP refers to them.

https://www.bmj.com/content/371/bmj.m3872/rr

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).

Another letter here listing multiple studies

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

This article talks about two US studies

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

whereas the effects of taking too much vitamin D are well documented and I've linked to them already, even if you're too lazy to follow them.

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.

Oi! He's my stalker. Go and get one of your own.

You can have him back now.

You can have him back now.

I'll pass

.... a big believer in supplements and suggested taking more than the standard dose (25 micrograms I think). He said it was difficult to overdose on Vitamin D and even if you did the side effects were minor.

All things considered, a daily vitamin D intake of 1000–4000 IU, or 25–100 micrograms, should be enough to ensure optimal blood levels in most people. 4000 IU is the safe upper limit according to the Institute of Medicine (IOM). Make sure not to take more than that without consulting with a health professional.

The upper level of harmless intake is set at 4000 IU, or 100 micrograms, per day.
However, up to 10,000 IU per day has not been shown to cause harm to healthy individuals

both the NHS and EFSA say Do not take more than 100 micrograms (4,000 IU) of vitamin D a day.

Yes, as below.

Incidentally the NHS recommends not taking more than 100 micrograms per day. Exactly the same as the article I linked.

The NHS and NICE recommend 10 micrograms.

Sunshine no good in the UK between October and March, any time that your shadow is longer than you are.

Yes, as below.

it's wonderful that you can have two contradictory opinions, and yet both of them are right.

It wasn’t expressing an opinion. I said this was what the article I had linked had to say about toxicity. That was a direct quote.
