Following is a small selection of information on the power of vitamin D – the health and immune benefits and it’s mode of action. Included is information on Vitamin D and COVID-19.
Vitamin D levels correlate strongly with SARS-CoV-2 infection severity,
with a theoretical point of zero mortality at approximately 50 ng/mL D3 – REF
Vitamin D administration results in a decreased risk of death and ICU admission.– REF
Overview on Vitamin D
This one hour presentation by Dr Michael F. Holick – a compelling overview of the power of vitamin D.
As temperature goes down (so too does the sunshine)
An interesting look at a time-laps video below showing as the US temperature drops (LEFT) the COVID-19 cases seem to follow along to some degree. When temperature decreases the tendency to stay outside reduces as well as the availability of sunshine hours decreases.
Dr Horick writes “when the angle of the sunlight (zenith angle) reaching the Earth’s surface is very oblique (ie, early morning, late afternoon, and winter), sunlight must pass through more ozone, which efficiently absorbs the previtamin D3-producing UVB photons, and thus very few, if any, reach the earth’s surface. Because the zenith angle is dependent on time of day, season of the year, and latitude, those factors have a dramatic effect on the cutaneous [skin] production of vitamin D3“
Dr Joe Prendergast & and Dr Liz Lipski on Vitamin D
Vitamin D is really a hormone. The whole immune system would become measurably stronger by a factor of 3-5 times, probalby better than any vaccines, for any virus. – Dr Prendergast – circa 2007
“57% of us a vitamin D deficient”, 92% of people with high pigmented skin are vitamin D deficient, making one more susceptible to colds and flu, amongst other things – Dr Liz Lipski 2008
[Vitamin D] has antimicrobial, antiviral activity

Despite ongoing vaccinations, we recommend raising serum 25(OH)D levels to above 50 ng/mL to prevent or mitigate new outbreaks due to escape mutations or decreasing antibody activity.”

- Macrophages (primary white blood cells) are part of your innate immune system. There are two types of macrophages – M1 – Pro-inflammatory which support anti-microbial properties and M2 Anti-inflammatory which supports tissue repair
