Experts Weigh in on Vitamin D for COVID-19

STORY AT-A-GLANCE

  • Dr. Michael Holick, widely recognized as one of the leading vitamin D experts in the world, physicist Gareth Davies, Ph.D., and Drs. William Grant and David Grimes present important information about vitamin D as it relates to COVID-19
  • Vitamin D can strengthen your immune system in a matter of a few weeks, and according to recent research, correcting vitamin D deficiency could save thousands of lives in Great Britain alone
  • Hospitalized COVID-19 patients given supplemental calcifediol (a vitamin D3 analog) in addition to standard of care lowered ICU admissions from 50% to 2% — and eliminated deaths
  • Another study found COVID-19 patients with a vitamin D level of at least 30 ng/mL had a significantly lower risk of adverse clinical outcomes, including a 51% lower risk of dying
  • Based on data from 191,779 American patients, people with a vitamin D level of at least 55 ng/mL (138 nmol/L) had a 47% lower SARS-CoV-2 positivity rate compared to those with a level below 20 ng/mL (50 nmol/L)

Vitamin D Cuts SARS-CoV-2 Infection Rate by Half

STORY AT-A-GLANCE

  • Based on data from 191,779 American patients, people with a vitamin D level of at least 55 ng/mL (138 nmol/L) had a 47% lower SARS-CoV-2 positivity rate compared to those with a level below 20 ng/mL (50 nmol/L)
  • Based on data from 7,807 Israelis, those with a vitamin D level above 30 ng/mL (75 nmol/L) had a 58% to 59% lower risk of testing positive for SARS-CoV-2 compared to those with a vitamin D level below 29 ng/mL (74 nmol/L)
  • Having a vitamin D level below 30 ng/mL also approximately doubles your risk of being hospitalized with COVID-19, Israeli researchers found
  • Spanish researchers found giving hospitalized COVID-19 patients supplemental calcifediol (a vitamin D3 analog) in addition to standard of care lowered ICU admissions from 50% to 2% and eliminated deaths
  • An August 2020 study found patients who had a vitamin D level below 12 ng/mL (30 nmol/L) had a 6.12 times higher risk of severe disease requiring invasive mechanical ventilation, and a 14.7 times higher risk of death compared to those with a vitamin D level above 12 ng/mL
