Vitamin D deficiency
A key to regulating the immune system

>  Over 80% of Black Americans, 69% of Hispanics, and approximately 30% of Whites have been shown to be deficient in vitamin D[20]

>  The scientific evidence shows a strong association between vitamin D deficiency states and higher rates of COVID-19 infection, severe cases (hospitalization, ICU admissions) and deaths. [48] [49] [50] [51]

>  Over 200 scientists and doctors from 33 countries have signed the Dec 7, 2020 open letter. This letter calls on all governments, and public health agencies to immediately implement widespread increased vitamin D intakes to combat COVID-19 infections, severe cases and deaths. The letter can be viewed HERE

ZINC (Zn) deficiency

Gatekeeper of Immune Function

>  ZINC DEFICIENCY IS NOT RARE. At least 20% of US adults over 60 years old and 30% of those in elder-care homes are at risk for zinc deficiency. [63]

>  Zinc directly inhibits viral replication. It is involved in multiple processes that deactivate and block replication of COVID-19. [91] [92] [93] [94]

>  Research studies have shown a strong correlation between zinc deficiency states and more severe COVID-19 disease and death. [34] [71] [72]

Vitamin C deficiency

A Key to Defending the Lungs

>  Within the US, between 10—15%  of people between 12 and 74 may be deficient. [119] Significantly higher rates of deficiency have been seen in older adults around the world. [128] [129] [130] [131]

>  Blacks may be 20% more likely to be deficient than Whites. [120]

>  Research studies have shown a correlation between vitamin C deficiency states and more severe COVID-19 outcomes. [139] [140]

Selenium (Se) deficiency

A key to reducing virus harm

>  Worldwide, it is estimated that over one billion people (1 in 7) may be selenium deficient.


>  Research studies on selenium levels in older adults (over age 65) around the world have shown deficiency rates exceeding 30% in many areas. [9] [147] [156]

>  Research studies have shown a strong correlation between selenium deficiency and severe COVID-19 disease and deaths. [163] [164]
