The evidence for a relationship between vitamin D, immune function, and COVID-19 outcomes continues to grow. Many studies have noted a relationship between circumstances in which vitamin D deficiency is more prevalent (such as obesity, climatic factors and geographic location, darker skin, and certain health conditions), and the increased odds of COVID-19 severity and mortality. In addition, studies on COVID-19 patient data have shown an increased risk for COVID-19 incidence and severity among those with lower vitamin D levels, or decreased severity among patients receiving vitamin D supplementation, and more continue to be published.

Hospitalized Patients with Lower Vitamin D were Worse Off

A newly published study by Panagiotou et al. examined data from 134 patients hospitalized with COVID-19 to determine if baseline vitamin D levels were related to severity of the disease. Those patients identified as having a vitamin D level of 16 ng/ml (40 nmol/L) or less were eligible for treatment with a single large dose of vitamin D (100,000-300,000 IU, depending on baseline level), followed by either 800 or 1600 IU vitamin D daily; those with levels between 16-29 ng/ml (41-74 nmol/L) were eligible for treatment with 800 IU/day.

The study found that those patients admitted to the intensive treatment unit (ITU) due to more severe COVID-19 symptoms had lower vitamin D levels compared to those who did not require admission. Only 19% of the ITU patients had a vitamin D level of at least 20 ng/ml (50 nmol/L) compared to 39 % of non-ITU patients (p=0.02).

Other factors related to intensive treatment unit (ITU) admission were hypertension, obesity, higher baseline respiratory rate, higher C-Reactive protein (CRP) levels, and interestingly, those younger in age (61 years vs 76 years old, p<0.001).

Are You Getting Enough Vitamin D to Help Yourself?

We’re in a time of great crisis that could be greatly affected by making sure you and everyone you know has a serum level of at least 40 ng/ml. Help us help you.

Do you know what your vitamin D level is? Be sure to test today to find out, and take steps to keep it within a target of 40-60 ng/ml or 100-150 nmol/L! Give your immune system the nutrients it needs to support a healthy you and protect yourself from unnecessary diseases.

GrassrootsHealth Nutrient Research Institute is preparing to do a Community RCT with the use of our myData-myAnswers nutrient health system that over 15,000 people are already using for their health. We will demonstrate how one can use the Nutrient Research Model established by Dr. Robert Heaney to establish the effect of vitamin D serum levels of at least 40 ng/ml (100 nmol/L) on risk reduction with different ethnicities in the population. Please let us know if you’re interested in helping sponsor this project.
