A recent German study found a linear relationship between vitamin D levels and mortality from covid, and essentially, zero morbidity for those with a D level above 50 ng/mL.
“At a threshold level of 30 ng/mL, mortality decreases considerably. In addition, our analysis shows that the correlation for the combined datasets intersects the axis at approximately 50 ng/mL, which suggests that this vitamin D3 blood level may prevent any excess mortality."
Studies have already shown that one is 14 times more likely to die from COVID with vitamin D deficiency.
A meta-analysis of 23 published studies containing 11,901 participants found that one who is vitamin D-deficient was 3.3 times more likely to get infected with SARS-CoV-2 than one who is not deficient.
The reality is that most people’s levels are below 30 and many are closer to zero, especially among the elderly population.
With studies having shown zero correlation between lockdowns, masks, and vaccines and better COVID outcomes, there are now 142 studies vouching for the near-perfect correlation between higher vitamin D levels and better outcomes in COVID patients.
It is beyond criminal that 20 months into this endeavor there has not been a national campaign percolating down to primary care physicians to test and supplement vitamin D levels accordingly.
As the authors explain, the main cause of death from COVID stems from a “cytokine storm” when the body’s immune system releases too many toxic cytokines as part of the inflammatory response to the virus.
Vitamin D is the key regulator of those cells, and the insufficient amount of D is nearly synonymous with a greater risk for a cytokine storm.
In many ways, a cytokine storm is literally the outcome of vitamin D deficiency.

Optimal Vitamin D levels (100 – 150 nmol/L) play a positive role in making sure that your body functions the way it was developed. There are Vitamin D Receptors (VDR) located in tissue throughout your body and in all the major organs. Vitamin D interacts with over 3,000 genes.
The benefit of an adequate vitamin D level to each individual will be better overall health and a reduction of illnesses. In addition to rickets, bone disease and osteomalacia/osteoporosis, vitamin D insufficiency is associated with many other diseases including: tuberculosis, psoriasis, multiple sclerosis, inflammatory bowel disease, type-1 diabetes, high blood pressure, increased heart failure, myopathy, breast and other cancers. It is projected that the incidence of many of these diseases could be reduced by 20%-50% or more, if the occurrence of vitamin D deficiency and insufficiency were eradicated by increasing vitamin D intakes through increased UVB exposure, fortified foods or supplements.
A summary of the health benefits and disease incidence prevention that could be achieved by raising the public's vitamin D levels to 125 nmol/L:
Rickets, reduced by 100%
Osteomalacia, reduced by 100%
Cancers, all combined, reduced by 75%
Breast Cancer, reduced by 50%
Ovarian Cancer, reduced by 25%
Colon Cancer, reduced by 67%
Non-Hodgkins, reduced by 30%
Kidney Cancer, reduced by 67%
Endometrial Cancer, reduced by 35%
Type 1 Diabetes, reduced by 80%
Type 2 Diabetes, reduced by 50%
Fractures, all combined, reduced by 50%
Falls, women reduced by 72%
Multiple Sclerosis, reduced by 50%
Heart Attack, men, reduced by 50%
Peripheral Vascular Disease, reduced by 80%
Preeclampsia reduced by 50%
Cesarean Section, reduced by 75%

You may have noted that I'm saying nothing, since I'm just quoting one of the most focused resources available on Vitamin D, ie the "Vitamin D Society".

Humans evolved in the horn of Africa, close to the Equator over 30,000 years ago. They spent their days out in the full sun, with no clothing, hunting and gathering food. Their skin pigment evolved and protected them from sun burns and allowed the production of vitamin D through the skin. Nature never intended for humans to live and work indoors, in cubicles, without sunshine exposure.

GrassrootsHealth and over 40 Vitamin D Scientists recommend achieving an optimal Vitamin D level for disease prevention of 100-150 nmol/L using a 25(OH)D blood test. This is the natural levels that the human body had as it evolved over thousands of years. Everyone should have their vitamin D 25(OH)D blood serum levels tested and make sure they are within these guidelines.
Please see also ICWB (former "Vitamin D Council", which was one of the first association to actively promote Vit D on a large, public scale). These pages especially, regarding recommended dosages and risks of overdosing:

Overall, 4,000 or 5,000 UI per day (and up to 10,000 UI in case of deficiency and/or no supplementation in the recent past) looks like the optimal dose on the long run.
