Deficiency of vit D limits the performance of systems resulting in, increased spread of diseases of civilization
Reduced protection against infections
Reduced effectiveness of vaccination
Covid fatality rates correlate with,
Elderly, dark, black people, comorbidities, winter
Blood level of 20 ng/mL, (50 nmol/L) sufficient to stop osteomalacia
Preferable, 40–60 ng/mL (100 to 150 nmol/L)
Vitamin D3 receptors
Bone
Intestine
Pancreas
Prostate
Immune system cells
Vitamin D is a powerful epigenetic regulator
Influencing more than 2,500 genes
Cancer
Diabetes mellitus
Acute respiratory tract infections
Viral lung infections that cause ARDS
Chronic inflammatory diseases
Autoimmune diseases
Multiple sclerosis
Immunomodulatory properties
Regulating innate and adaptive immune systems
D3 receptors
Monocytes/macrophages

B cells
Natural killer (NK) cells
Dendritic cells (DCs)
Supplements
Without calcium supplementation, even very high vitamin D3 supplementation does not cause vascular calcification
Vitamin D3 supplementation in the range of 4000 to 10,000 units (100 to 250 µg) needed to generate an optimal 40–60 ng/mL (100 to 150 nmol/L)
has been shown to be completely safe when combined with approximately 200 µg vitamin K2

However, this knowledge is still not widespread in the medical community, and obsolete warnings about the risks of vitamin D3 overdoses unfortunately are still commonly circulating.
ARDS and cytokine release syndrome
Vitamin D3 is able to inhibit the underlying metabolic pathways
Vitamin D3 has a protective role against ARDS caused by SARS-CoV-2.
A rapidly increasing number of publications are investigating the vitamin D3 status of SARS-CoV-2 patients,
and have confirmed low vitamin D levels in cases of severe courses of infection
and positive results of vitamin D3 treatments
Conclusions
we recommend raising serum 25(OH)D levels to above 50 ng/mL (100 to 150 nmol/L)
to prevent or mitigate new outbreaks due to escape mutations or decreasing antibody activity.
