I only ask as some were mentioning 3-4000U earlier in the thread. I've got 3000U and hopefully I won't have overdosed before I get inoculated.
Although that is for severe deficiency, and isn't given everyday....I’ve been taking 3,000IU daily for the past 2 years and no issues. So since long before Covid reared it’s head.
The capsule I take has 3000IU Vitamin D3 and 100 IU of Vitamin K2.
As has been mentioned, VitD can cause increased blood calcium, and this is what the K2 addresses (keeps calcium where it should be : in the bones).
My elderly mother (aged over 80) also takes it but she takes it every other day.
They do give it in hospitals in doses of 60,000IU. VitaminD is converted by the body into Calcifediol but that process takes 7 days, so some ICU go straight to giving Calcifediol.
If you're back of the Q for vaccine bear in mind that come May through to September that 3000iu plus even quite short sun exposure times would be enough to possibly push your daily Vit D intake higher than you think (if not using sunscreen). See my post above.I only ask as some were mentioning 3-4000U earlier in the thread. I've got 3000U and hopefully I won't have overdosed before I get inoculated.
I bought mine from a High Street Pharmacy in the hope that they use a reputable supplier.Last year it was recommended to me to take vitamin C and D tablets, but how do you know that what you're buying is what the label says? It used to be that they weren't regulated, but has that changed now?
I would take just a multi vitamin if you need vitamin C, be better wouldn't it? As can get other benefits too if you are unknowingly low on something else.

Don't Hollands & Barrett take orders online and deliver? I expect they'd be a very good place to source some Vitamin D.
I would say your analysis is wrong. The paper states that they didn’t find evidence that VitD can prevent or affect the severity of Covid-19.According to a new paper in the BMJ it's now looking like those early studies were probably over egging the benefits, at least for people with European ancestry.
Interesting that two studies have no shown no correlation between circulation Vit D levels and COVID resistance, despite being habitual users. More research on other correlations required methinks.
Full quote from the conclusions:“Our findings suggest that habitual use of vitamin D supplements is related to a lower risk of COVID-19 infection”.
Personally I suspect that many people habitually take a very small dose in a multi-vitamin, and that likely has little or less effect. Those taking a significant dose, enough to raise them out of the “low vitamin d” bracket, probably reap the benefit.
Basically there is a big difference between me taking 3000 IU a day compared to my father in law who gets 300 IU in his daily multi-vitamin.
