Vitamin D Prevents Covid

Recent meta-analysis of Covid-19 research has definitively concluded that Vitamin D

supplementation has a significant preventative effect on the severity of Covid infection and prevention of infection to start with. Here are the bullet points from the studies:


  • Promotes and optimizes immune response

  • Anti-inflammatory

  • Antioxidant

  • Vitamin D maintains pulmonary barrier function

  • Determines the production of antimicrobial peptides

  • Enhances neutrophil activity

  • Enhances T helper cells - essential for immune function

  • Reduces pro-inflammatory cytokines - prevents “cytokine storm”

  • Reduce risk of asthma exacerbations

  • Prevents acute respiratory infections and reduces complications

  • Reduces rates of ICU admission, mortality events, and PCR positivit

In fact, the data suggests that Vitamin D has higher preventative efficacy for serious illness than “leading treatments.” This includes the prevention of becoming infected!


At this point, I would be remiss, and even consider it unethical, to NOT share this news with you.


Here are the recommendations for Vitamin D supplementation based on the evidence.

  • Blood Test to determine if serum 25-hydroxy vitamin D in range of >50 and < 80ng/mL

  • 5,000 IU Vitamin D/day until levels are optimal

  • Skin exposure to sunlight daily will help raise your levels

Here are the studies for your consideration:

  1. Protective Effect of Vitamin D Supplementation on COVID-19-Related Intensive Care Hospitalization and Mortality: Definitive Evidence from Meta-Analysis and Trial Sequential Analysis

  2. COVID-19 and vitamin D (Co-VIVID study): a systematic review and meta-analysis of randomized controlled trials

  3. Effects of a 2-Week 5000 IU versus 1000 IU Vitamin D3 Supplementation on Recovery of Symptoms in Patients with Mild to Moderate Covid-19: A Randomized Clinical Trial

  4. Effect of calcifediol treatment and best available therapy versus best available therapy on intensive care unit admission and mortality among patients hospitalized for COVID-19: A pilot randomized clinical study

  5. Changes in the immune response against SARS-CoV-2 in individuals with severe COVID-19 treated with high dose of vitamin D

  6. Calcifediol treatment and COVID-19-related outcomes
