Study: Vitamin D may reduce risk of and treat COVID-19


Vitamin D supplements

A recent study suggests that Vitamin D reduces the risk of infection with COVID-19 and influenza and could help treat those already infected with COVID-19.

The following is the abstract of the study, re-printed in its entirety:

Abstract

The world is in the grip of the COVID-19 pandemic. Public health measures that can reduce the risk of infection and death in addition to quarantines are desperately needed. This article reviews the roles of vitamin D in reducing the risk of respiratory tract infections, knowledge about the epidemiology of influenza and COVID-19, and how vitamin D supplementation might be a useful measure to reduce risk. Through several mechanisms, vitamin D can reduce risk of infections. Those mechanisms include inducing cathelicidins and defensins that can lower viral replication rates and reducing concentrations of pro-inflammatory cytokines that produce the inflammation that injures the lining of the lungs, leading to pneumonia, as well as increasing concentrations of anti-inflammatory cytokines. Several observational studies and clinical trials reported that vitamin D supplementation reduced the risk of influenza, whereas others did not. Evidence supporting the role of vitamin D in reducing risk of COVID-19 includes that the outbreak occurred in winter, a time when 25-hydroxyvitamin D (25(OH)D) concentrations are lowest; that the number of cases in the Southern Hemisphere near the end of summer are low; that vitamin D deficiency has been found to contribute to acute respiratory distress syndrome; and that case-fatality rates increase with age and with chronic disease comorbidity, both of which are associated with lower 25(OH)D concentration. To reduce the risk of infection, it is recommended that people at risk of influenza and/or COVID-19 consider taking 10,000 IU/d of vitamin D3 for a few weeks to rapidly raise 25(OH)D concentrations, followed by 5000 IU/d. The goal should be to raise 25(OH)D concentrations above 40–60 ng/mL (100–150 nmol/L). For treatment of people who become infected with COVID-19, higher vitamin D3 doses might be useful. Randomized controlled trials and large population studies should be conducted to evaluate these recommendations.

  1. Please do NOT disseminate this information, we need to develop a Bill Gates-sponsored mandatory RNA vaccine in hurry, we need to help that villain fatten his pocket, his influence., and his off shore wealth., we need to implement a global digital certificate surveillance system . Let’s all help that good messianic, altruistic philanthropist save the world.

  2. I was put on a high dose of Vitamin D three years ago for osteoporosis after breaking several bones in a simple fall. After hearing some of this a few weeks ago I’ve realized I haven’t been sick since then and the seasonal allergies I suffered with for 40 years are almost non-existent.

  3. Been taking vitamin D3 for 11 years, one fever in that time period which I believe was associated with an infected tooth. No flu, etc during these 11 years

    I am a registered dietitian. I have been saying this since the start of the pandemic. The people who are more at risk for complications: elderly do not go outside, black people do not make it as readily. Obese people are more likely to have low levels. One study estimated that 40% of people are low. I see deficiency at least once a month & that is being very conservative in my estimations. It is known that 90% of cancer patients are low in vitamin D. Symptoms are very non-descript. You might feel tired & get sick more often. There was an article from 1918 Pandemic that stated those patients who were taken outside in the fresh air & sunshine faired better. Vitamin D is known to prevent the common cold. Good sources are salmon, mushrooms, fortified milk products & liver. We get make less because of sunscreen. I recommend at least 2000-5000 IU. Don’t take more because more is not better. I knew of someone who was taking higher than 10,000 IU & ended up in the hospital with high calcium levels which can be fatal.

  5. This is making of a lot of sense. There has been a lot of talk about this. But what I don’t understand is that, why isn’t the government telling us this. Why are they keeping quiet about the lack of Vitamin D and covid-19 correlation. Something is not right.
