Quercetin and Vitamin D — Allies Against Coronavirus Mercola March 16
How Quercetin Inhibits Viral Infection
- Inhibiting the virus' ability to infect cells
- Inhibiting replication of already infected cells
- Reducing infected cells' resistance to treatment with antiviral medication
- - - - - - - -
- "A 1985 study, which found quercetin inhibits infectivity and replication of herpes simplex virus type 1, polio-virus type 1, parainfluenza virus type 3 and respiratory syncytial virus."
- "Another 2016 study found quercetin offered protection against influenza A virus H1N1 by modulating protein expression. More specifically, the regulation of heat shock proteins, fibronectin 1 and prohibitin was instrumental in reducing viral replication."
- "Most recently, a March 2020 stud y24 in the Microbial Pathogenesis journal found quercetin "provides comprehensive protection against Streptococcus pneumoniae infection," both in vitro and in vivo, primarily by neutralizing pneumolysin (PLY),25"
- In the featured MedCram video, pulmonologist Dr. Roger Seheult discusses the importance of vitamin D for the prevention of COVID-19. While there are no clinical trials investigating vitamin D for coronavirus specifically, there are plenty of data showing it's an important component in the prevention and treatment of influenza26 and upper respiratory tract infections.27
- As noted by Seheult, while vitamin D does not appear to have a direct effect on the virus itself, it strengthens immune function, thus allowing the host body to combat the virus more effectively.28 It also suppresses inflammatory processes. Taken together, this might make vitamin D quite useful against COVID-19.
- As explained by Seheult, robust immune function is required for your body to combat the virus, but an overactivated immune system is also responsible for the cytokine storm we see in COVID-19 infection that can lead to death.
- "What we want is a smart immune system," Seheult says, "An immune system that takes care of the virus but doesn't put us into an inflammatory condition that could put us on a ventilator."

- Vitamin D Receptor is associated in over 58 autoimmune studies

- Hand, foot, and Mouth disease is 14X more likely if poor Vitamin D Receptor – Oct 2019
- Treating herpes reduced incidence of senile dementia by 10 X (HSV1 reduces VDR by 8X) – 2018
- Severe hand, foot, and mouth virus is 2.9 X more likely if poor Vitamin D receptor – Oct 2018
- Hepatitis B virus reduced by 5X the Vitamin D getting to liver cells in the lab – Oct 2018
- Some enveloped virus are 1.2 X more likely if have a poor Vitamin D Receptor -Aug 2018
- Severe Pertussis is 1.5 times more likely if poor vitamin D receptor – Feb 2016
- Dengue Fever associated with poor vitamin D receptor – July 2002
- Dengue virus 2X to 4X more likely if vitamin D receptor gene problems
Vitamin D Receptor activation can be increased by any of: Resveratrol, Omega-3, Magnesium, Zinc, Quercetin, non-daily Vit D, Curcumin, intense exercise, Ginger, Essential oils, etc Note: The founder of Vitamin D Life uses 10 of the 12 known VDR activators
Vitamin D Receptor category has the following
Vitamin D tests cannot detect Vitamin D Receptor (VDR) problems
A poor VDR restricts Vitamin D from getting in the cells
It appears that 30% of the population have a poor VDR (40% of the Obese )
A poor VDR increases the risk of 55 health problems click here for details
The risk of 44 diseases at least double with poor Vitamin D Receptor as of Oct 2019
VDR at-home test $29 - results not easily understood in 2016
There are hints that you may have inherited a poor VDR
Compensate for poor VDR by increasing one or more:
| Increasing | Increases |
| 1) Vitamin D supplement Sun, Ultraviolet -B | Vitamin D in the blood and thus in the cells |
| 2) Magnesium | Vitamin D in the blood AND in the cells |
| 3) Omega-3 | Vitamin D in the cells |
| 4) Resveratrol | Vitamin D Receptor |
| 5) Intense exercise | Vitamin D Receptor |
| 6) Get prescription for VDR activator paricalcitol, maxacalcitol? | Vitamin D Receptor |
| 7) Quercetin (flavonoid) | Vitamin D Receptor |
| 8) Zinc is in the VDR | Vitamin D Receptor |
| 9) Boron | Vitamin D Receptor ?, etc |
| 10) Essential oils e.g. ginger, curcumin | Vitamin D Receptor |
| 11) Progesterone | Vitamin D Receptor |
| 12) Infrequent high concentration Vitamin D Increases the concentration gradient | Vitamin D in the cells |
| 13) Sulfroaphone and perhaps sulfur | Vitamin D Receptor |
Note: If you are not feeling enough benefit from Vitamin D, you might try increasing VDR activation. You might feel the benefit within days of adding one or more of the above
Far healthier and stronger at age 72 due to supplements Includes 6 supplements which help the VDR
