Supplement reduce COVID positive VDW#11767
Data for the chart comes from table 4


Overvational study of mainly health-care workers in Chicago
Vitamin D levels were tested sometime in the year before being tested for COVID-19
Those whom most-supplemented with vitamin D were far less likely to test positive

Suspect 6X less likely to test positive if taking 10,000 IU for >3 months
Suspect 15X less likely to test positive if take a single dose of vitamin D (cost 4 cents) a few weeks before

Note: A RCT is starting in Sri Lanka in June 2020 to see if the suspection is correct

Importance: Vitamin D treatment has been found to decrease incidence of viral respiratory tract infection, especially in vitamin D deficiency. It is unknown whether COVID-19 incidence is associated with vitamin D deficiency and treatment.

Objective: To examine whether vitamin D deficiency and treatment are associated with testing positive for COVID-19. Design: Retrospective cohort study Setting: University of Chicago Medicine Participants: Patients tested for COVID-19 from 3/3/2020-4/10/2020. Vitamin D deficiency was defined by the most recent 25-hydroxycholecalciferol <20ng/ml or 1,25-dihydroxycholecalciferol <18pg/ml within 1 year before COVID-19 testing. Treatment was defined by the most recent vitamin D type and dose, and treatment changes between the time of the most recent vitamin D level and time of COVID-19 testing. Vitamin D deficiency and treatment changes were combined to categorize vitamin D status at the time of COVID-19 testing as likely deficient(last-level-deficient/treatment-not-increased), likely sufficient(last-level-not-deficient/treatment-not-decreased), or uncertain deficiency(last-level-deficient/treatment-increased or last-level-not-deficient/treatment-decreased).

Main Outcomes and Measures: The main outcome was testing positive for COVID-19. Multivariable analysis tested whether the most recent vitamin D level and treatment changes after that level were associated with testing positive for COVID-19 controlling for demographic and comorbidity indicators. Bivariate analyses of associations of treatment with vitamin D deficiency and COVID-19 were performed.

Results: Among 4,314 patients tested for COVID-19, 499 had a vitamin D level in the year before testing. Vitamin D status at the time of COVID-19 testing was categorized as likely deficient for 127(25%) patients, likely sufficient for 291(58%) patients, and uncertain for 81(16%) patients. In multivariate analysis, testing positive for COVID-19 was associated with increasing age (RR(age<50)=1.05, p<0.021; RR(age≥50)=1.02,p<0.064)), non-white race(RR=2.54,p<0.01) and being likely vitamin D deficient (deficient/treatment-not-increased: RR=1.77,p<0.02) as compared to likely vitamin D sufficient(not-deficient/treatment-not-decreased), with predicted COVID-19 rates in the vitamin D deficient group of 21.6%(95%CI[14.0%-29.2%] ) versus 12.2%(95%CI[8.9%-15.4%]) in the vitamin D sufficient group. Vitamin D deficiency declined with increasing vitamin D dose, especially of vitamin D3. Vitamin D dose was not significantly associated with testing positive for COVID-19.

Conclusions and Relevance: Vitamin D deficiency that is not sufficiently treated is associated with COVID-19 risk. Testing and treatment for vitamin D deficiency to address COVID-19 warrant aggressive pursuit and study.

Vitamin D Dosing Recommendations for COVID-19

  • Portion of image from June 5 video (below)
    • Image
  • Commentary: Myths and facts on vitamin D amidst the COVID-19 pandemic Metabolism, June 2, FREE PDF, peer-reviewed publication
    • "Preventive doses of vitamin D3 of 10,000 IU/day for 4 weeks followed by 5000 IU/day to reach a target 25(OH)D level of 100–150 nmol/L [24], and treatment doses >6000 IU/day in deficient individuals to reach a similar level and reduce disease progression [48], are suggested. ""
    • Comment: Strange that the treatment dose is less than the prevention dose. Note treatment dose will take > 3 months to help
      • Perhaps they meant the treatment dose to be 60,000 IU, not 6,000 IU
  • Perspective: improving vitamin D status in the management of COVID-19 May 22 free PDF
    • If low: 50,000 IU twice a week at the diagnosis (100,000 IU total)., then 50,000 IU taken once a week for the 2nd and 3rd weeks.
      • Note: VitaminDWiki believes that this dosing is not large enough for prevention, much less treatment
  • COVID-19 might be prevented in 2 months by 50,000 IU weekly – May 12, 2020
  • for people who have not been taking any vitamin D BusinessWorld May 22 - by Dr Renu Mahtani in videos below
    • Vitamin D 60k IU twice a week for two weeks to be followed by 60k once a week for the next six weeks.
    • or Vitamin D 60k IU daily for three days to be followed by 60k weekly for the total period of two months.
    • Thus 480,000 IU total, No Vitamin D testing needed

Some people wanted improved immune systems, so took more vitamin D
