D is SO important to so many things ... it’s actually a pre-hormone, not a vitamin.
Don’t know my mom’s Vit D status when she had a small melanoma. Due to low levels of D being implicated with higher mortality rates with COVID, we now have her up to 70 ng/ml and I suspect my dad is about the same. The recommendation for avoiding COVID issues is a D level of 50 ng/ml or higher.

Vitamin D for influenza

Last paragraph:
“A colleague of mine and I have introduced vitamin D at doses that have achieved greater than 100 nmol/L in most of our patients for the past number of years, and we now see very few patients in our clinics with the flu or influenzalike illness. In those patients who do have influenza, we have treated them with the vitamin D hammer, as coined by my colleague. This is a 1-time 50 000 IU dose of vitamin D3 or 10 000 IU 3 times daily for 2 to 3 days. The results are dramatic, with complete resolution of symptoms in 48 to 72 hours. One-time doses of vitamin D at this level have been used safely and have never been shown to be toxic.8 We urgently need a study of this intervention. The cost of vitamin D is about a penny for 1000 IU, so this treatment costs less than a dollar.”

I take 10,000 iu/day for chronic urticaria (hives). It pretty much keeps them under control & rarely do I have to take any antihistamines (& then just half a pill of fenofexadine). There was a study on it - 400 vs 4000 iu. Both doses saw benefit, but the lower amount was only effective for 2 weeks. I was taking 5000, but doubled that when I had COVID - hives situation was improved even more, so I’ve left it at that dose.
Vit D = good stuff!
Good stuff indeed! And it was only “discovered” in the 1920s.
