If the pharmaceutical industry had developed a single drug capable of:

Reducing cancer mortality by more than 25%

Reducing autoimmune disorders by 39%

Reducing type 1 diabetes by 88%

Preventing advancement of prediabetes to type 2 diabetes by 76%

Reducing peripheral vascular disease by 80%

Lowering risk of upper respiratory tract infections by 58%

Reducing covid infectivity by 54%

Reducing COVID 19 infection by up to 74%

Reducing covid RDS by 78%

Reducing COVID 19 hospitalizations by up to 22%

Reducing COVID 19 mortality by up to 45 – 66%

Accelerating COVID positive patients to COVID negativity by 66%

Reducing risk of preterm birth by 62%

Reducing risk of pre-eclampsia by more than 50%

Reducing gestational diabetes, 50%

Reducing infant dental caries, 75%

Reducing multiple sclerosis, 62%

Colon cancer, 80%

Cardiovascular mortality, 67%

Autoimmune disease, 39%

the drug would be heralded as a “miracle drug.”


With patent protection, this single drug sold worldwide would be the first trillion-dollar drug.


The sunshine vitamin D provides all these health benefits especially when an adequate amount is taken to sustain circulating concentrations of 25(OH)D of at least 30 ng/ mL, (75 nm / L) with the maximum benefit obtained with concentrations of 40- 60 ng/mL,(100 – 150 nm / L)


At least 30 ng/ mL.

Best, 40- 60 ng/mL.
