COVID-19 is a Vitamin D Deficiency Disease
Why do you think patients were purposefully exposed to sunlight during the "Spanish" Flu Epidemic of 1918?
By: James Paul Roguski September 21, 2020 310-619-3055
They realized that reasonable exposure to sunlight was actually good for their patients health.

"Active forms of vitamin D... can inhibit production of pro-inflammatory cytokines of a cytokine storm with a mechanism of action involving down regulation of NF-κΒ and inverse agonism on RORγ (10). They can also counteract the oxidative stress through activation of NRF-2 and p53-dependent pathways (10).
Therefore, we suggest that vitamin D3-hydroxyderivatives are candidates for management of COVID-19, because while targeting both the cytokine storm and oxidative stress, they might also have antiviral effects...
Vitamin D precursor... is readily available and can be consumed within reasonable doses without a need for such approval. According to the Endocrine Society, the upper daily limit for an average healthy adult individual is 10,000 IU/day. This oral dose could be applied preventively to reduce probability of moderate to severe COVID-19.
However, such a dose may not be sufficient to stop cytokine↔oxidative storm in patients entering the hospital, which would require aggressive solutions. In the past, mega doses of vitamin D were used to treat different pathologies (2).
These findings suggest the use of high doses of vitamin D after admission to the hospital, since patients can be carefully monitored for any signs of adverse effects."

"We agree with Jakovac (4) and Rocha et al. (8) that this calls for measurement of a 25(OH)D level in all COVID-19 patients. Patients who are vitamin D deficient or insufficient, i.e., 25(OH)D < 30 ng/mL could be treated with an appropriate amount of vitamin D as soon as it is feasible to do so. In summary, we believe that different forms and routes of delivery of vitamin D at proper and clinically monitored doses might help in prevention or management of moderate to severe COVID-19."
"Active forms of vitamin D3 by counteracting cytokine storm and oxidative stress will attenuate acute respiratory distress syndrome (ARDS) secondary to coronavirus disease."

PREVENTION:
Maintain blood levels between 75-100ng/ml by reasonable exposure to sunlight and consumption of 5,000-10,000 International Units (IU) of supplemental Vitamin D.
EMERGENCY TREATMENT:
Tell your doctor to consider the protocols used in THIS STUDY.
Vitamin D deficiency is made worse by
1. Sunblock
2. Skin with high levels of melanin
3. The closure of facilities that encourage outdoor activity
4. The excessive wearing of personal protective devices
5. Smoke from forest fires that block the rays of the sun

Elderly people of color who live in care facilities under artificial lighting, who don't go outside at all due to the "lockdowns" and put on sunblock when they do go outside are at far greater risk.
The "dis-ease" known as COVID-19 may be "triggered" by SARS-COV-2 but it is clearly aggravated by nutritional deficiencies that vary from person to person.
A clear comprehension of these nutritional deficiencies clearly correlates with the demographics of those who contract and die from COVID-19.
The fact that COVID-19 seems to manifest in dramatically different ways in different people, with different symptoms and pathologies is a testament to the unique nutritional status of every person on earth.
Numerous studies have shown that improving one's diet and AGGRESSIVELY supplementing with a wide variety of nutrients can be both preventative and therapeutic in all cases of COVID-19.
It is certainly true that belated attempts to reverse long-standing nutritional deficiencies in patients suffering with COVID-19 are not guaranteed to bring patients back from the brink of death.
It is ABSOLUTELY true that providing aggressive nutritional supplementation as both a preventative and treatment is a hell of a lot better than the current medical protocols:
CURRENT MEDICAL STANDARD OF CARE:
- Deny the benefits of adequate nutrition
- Do NOTHING for prevention
- Do NOTHING for immediate care
- Ban drugs such as hydroxychloroquine after conducting trials that were designed to fail because they did not include zinc in the protocols along with the hydroxychloroquine.
- Receive thousands of dollars for treatment with ineffective experimental drugs such as Remdesivir.
- Allow the patients' condition to deteriorate to the point where it then appears justified to implement invasive, "heroic," emergency techniques that actually do more harm then good (ventilators).
- Receive tens of thousands of dollars for patients placed on ventilators, even if they ultimately die.
Get the basics of Vitamin D
Vitamin D and COVID-19:
Vitamin D deficiency is STRONGLY correlated with the rate of deaths due to COVID-19. Government enforced "lock-downs" of outdoor activity further lower Vitamin D levels which is beginning to be noticed even in children, many of whom have been forced to stay indoors during the summer of 2020.
By definition, "people of color" have more melanin pigment in their skin and thus they tend to naturally produce less Vitamin D.
Viruses such as influenza ("the flu") classically occur during the winter months when sunlight levels are low, implying a connection to lower Vitamin D levels.
DETAILS
Testing labs in the United States generally report 25(OH)D levels in ng/mL (µg/mL). Other countries often use nmol/L (µmol/L). Multiply ng/mL by 2.5 to convert to nmol/L.
Acute overdose requires between 15,000 µg/d (600,000 IU per day) and 42,000 µg/d (1,680,000 IU per day) over a period of several days to months.
Acute overdose requires between 15,000 µg/d (600,000 IU per day) and 42,000 µg/d (1,680,000 IU per day) over a period of several days to months.
21 studies show evidence that optimum levels of vitamin D in the blood may reduce your risk from COVID-19. Start taking Vitamin D supplements and tell your doctor to schedule a Vitamin D blood test.
Calcifediol vs. Cholecalciferol
1. Oral calcifediol results in a more rapid increase in serum 25-OHD compared to oral cholecalciferol.
2. Oral calcifediol is more potent than cholecalciferol, so that lower dosages are needed. Based on the results of nine RCTs comparing physiologic doses of oral cholecalciferol with oral calcifediol, calcifediol was 3.2-fold more potent than oral cholecalciferol. Indeed, when using dosages ≤ 25 μg/day, serum 25OHD increased by 1.5 ± 0.9 nmol/l for each 1 μg cholecalciferol, whereas this was 4.8 ± 1.2 nmol/l for oral calcifediol.
3. Oral calcifediol has a higher rate of intestinal absorption and this may have important advantages in case of decreased intestinal absorption capacity due to a variety of diseases.
4. A potential additional advantage of oral calcifediol is a linear dose-response curve, irrespective of baseline serum 25OHD, whereas the rise in serum 25OHD is lower after oral cholecalciferol, when baseline serum 25OHD is higher.
5. Intermittent intake of calcifediol results in fairly stable serum 25OHD compared with greater fluctuations after intermittent oral cholecalciferol.

The intervention group received calcifediol, which is a type of vitamin D found in the blood. It is not the usual type of vitamin D found in supplements. Calcifediol is also known as 25(OH)D or 25-hydroxyvitamin D. The reason for giving this type of vitamin D is that the usual supplement type takes about 7 days to turn into calcifediol, so by giving patients calcifediol itself, you get the good effects without having to wait 7 or so days.
Vitamin D (in the form of oral calcifediol)
Patient’s Vitamin D status should be measured (blood test) and monitored
0.532 mg on day 1
0.266 mg on day 3
0.266 mg on day 7
and then 0.266mg weekly until discharge or ICU admission.
Please note: This is a different form of Vitamin D, and it is measured in mg, not IU.

Vitamin D has been clearly documented to strengthen immune function and decrease the risk of infection from any pathogen, including the COVID-19 virus. Patients with the highest vitamin D levels have shorter and less symptomatic courses of infection.
While vitamin D has not been demonstrated to cure viruses as a monotherapy, maintaining an adequate level of vitamin D is vital for both preventing the contraction of infectious diseases as well as for recovering more rapidly from such infections, with a clear decrease in mortality rate. [8]
In a recent study not yet published, Indonesian researchers studied the effects of vitamin D on mortality in 780 patients hospitalized with COVID-19. They found that nearly all (98.9%) of COVID-19 patients with vitamin D levels below 20 ng/ml died. Yet, less than 5% with substantially higher levels of vitamin D died.
Consistent with these findings, it has been shown that the most life-threatening complication of COVID-19 infection, acute respiratory distress syndrome, occurs much more readily in the presence of a vitamin D deficiency. [9]
Clearly, vitamin D supplementation should be part of any treatment protocol for COVID-19 or any other infectious disease.
Healthy people should not take ultra-high doses of vitamin D, but only normal doses up to 10,000 IU per day. That is a completely safe dose as you can easily get these amounts though sun-exposure. Children may receive 1,000 IU per each 11 pounds (200 IU per 1 kg of body weight daily).
Please note: The form of Vitamin D3 that is available as a supplement is a different form of Vitamin D (cholecalciferol), and it is measured in IU, not mg as was the case in the published study referenced above (calcifediol).
Vitamin D is soluble in oil, not in water. So, when mixed in a lipid vehicle vitamin D is better absorbed and should produce a better effect. A lipid vehicle requires soft gels or oil drops.

Vitamin D3 (commonly known simply as “vitamin D,” but formally as cholecalciferol) may be the most potent defense available against COVID-19, from the studies described below. It may also be the most easily acquired COVID-19 treatment, because vitamin D is produced in the skin on exposure to sunlight, with further processing in the liver and then in the kidneys to its fully useful form.
In this large Israeli study of over 7,000 people, "low plasma [vitamin D] levels almost doubled the risk for hospitalization due to the COVID-19 infection in the Israeli studied cohort." Also, "the mean plasma vitamin D level was significantly lower among those who tested positive than negative for COVID-19." (1)
In a retrospective cohort study in Indonesia of 780 cases of COVID-19 positive patients, it was found that those with below normal vitamin D levels were associated with increasing odds of death. (2)
The correlation among low serum vitamin D levels and COVID-19 mortality was so high in that study that this nutrient may turn out to be the most decisively valuable against COVID-19. This graph (3) shows the stark contrast found between high and low vitamin D levels and COVID-19 survivability.
In European countries also, a significant inverse relationship was found between serum vitamin D levels and COVID-19 mortality. Mean levels of vitamin D and COVID-19 mortality in twenty European countries were examined. Also aging populations, which have been the worst affected by COVID-19 were found to have the lowest serum vitamin D levels. (4)
Vitamin D is known to be essential to the maturing of macrophages, which in turn are a necessary tool of the immune system against pathogenic microbes. Macrophages with vitamin D also produce hydrogen peroxide, an important pro-oxidant molecular weapon against microbial pathogens. (5) However, vitamin D also stimulates production of anti-microbial peptides that appear in natural killer cells and neutrophils in respiratory tract epithelial cells, where they are able to protect the lungs from the ravages of infection.
One of the most alarming features of COVID-19 disease in the clinical setting has been the “cytokine storm,” which is itself life-threatening. It is an inflammatory over-reaction to the replicating viral pathogen. The utility of Vitamin D for the COVID-19 patient may best be appreciated in its prevention of excessive inflammatory cytokines, thereby sparing the patient of the body’s most severe reactions to the virus. (6) Vitamin D deficiency is also implicated in acute respiratory distress syndrome. (7)
Respiratory infectious disease prevalence has a strong seasonality through the centuries and around the world. That season peaks in the winter and early spring, after the year’s fewest hours and lowest angle of sunlight on the winter solstice. That lack of sunlight occurs during a time of the least skin surface exposed to freezing weather, and therefore the least endogenous vitamin D production. Supplementation of oral vitamin D through this difficult season may therefore be a prudent prophylaxis.

Summary
Having high blood levels of vitamin D reduces Covid-19 risks, including risk of infection [7, 8, 9, 11, 12, 14, 16, 20], of having a severe case [1, 3, 4, 5, 15, 17, 22], of needing hospitalization, ICU care, and/or mechanical ventilation [2, 10, 14, 15, 22], as well as the risk of dying from Covid-19 [4, 6, 7, 9, 12, 13, 17, 18, 19, 20, 22].
Vitamin D Other Benefits
In addition to reducing various types of risk related to Covid-19, vitamin D has other health benefits. Studies have shown that a high intake of vitamin D reduces risk of stroke [28], multiple sclerosis [29], rheumatoid arthritis [30], type 2 diabetes [31], breast cancer [32], prostate cancer [33], colon cancer [34], and all-cause mortality [35]. In older men, low vitamin D increased risk of mortality 83% as compared to men with optimal levels [36].
Vitamin D can be taken daily or once-a-week. Do not take a “bolus dose” of once a month or once every so-many months, as this has been shown to be less effective against acute respiratory tract infections, so it might be less effective against Covid-19.

Vitamin D has been clearly documented to strengthen immune function and decrease the risk of infection from any pathogen, including the COVID-19 virus. Patients with the highest vitamin D levels have shorter and less symptomatic courses of infection. While vitamin D has not been demonstrated to cure viruses as a monotherapy, maintaining an adequate level of vitamin D is vital for both preventing the contraction of infectious diseases as well as for recovering more rapidly from such infections, with a clear decrease in mortality rate. [A]
In a recent study not yet published, Indonesian researchers studied the effects of vitamin D on mortality in 780 patients hospitalized with COVID-19. They found that nearly all (98.9%) of COVID-19 patients with vitamin D levels below 20 ng/ml died. Yet, less than 5% with substantially higher levels of vitamin D died. Consistent with these findings, it has been shown that the most life-threatening complication of COVID-19 infection, acute respiratory distress syndrome, occurs much more readily in the presence of a vitamin D deficiency. [B] Clearly, vitamin D supplementation should be part of any treatment protocol for COVID-19 or any other infectious disease.
