Lately, there’s been some suggestion that vitamin D is “fake news.” Let’s take a closer look at what the research actually says:

• Analysis of vitamin D level among asymptomatic and critically ill COVID-19 patients and its correlation with inflammatory markers
• Association of Vitamin D Deficiency and Treatment with COVID-19 Incidence
• Covid-19 and Vitamin D Supplementation: a Multicenter Randomized Controlled Trial of High Dose Versus Standard Dose Vitamin D3 in High-risk COVID-19 Patients (CoVitTrial)
• Does vitamin D deficiency increase the severity of COVID-19?
• Evidence Regarding Vitamin D and Risk of COVID-19 and Its Severity
• Evidence that Vitamin D Supplementation Could Reduce Risk of Influenza and COVID-19 Infections and Deaths
• Low serum 25‐hydroxyvitamin D (25[OH]D) levels in patients hospitalised with COVID‐19 are associated with greater disease severity
• Nutritional status of patients with COVID-19
• Sixty seconds on . . . vitamin D
• The role of vitamin D in the prevention of coronavirus disease 2019 infection and mortality
• Vitamin D and Inflammation: Potential Implications for Severity of Covid-19
• Vitamin D and the anti-viral state
• Vitamin D deficiency as a predictor of poor prognosis in patients with acute respiratory failure due to COVID-19
• Vitamin D in the prevention, prediction and treatment of neurodegenerative and neuroinflammatory diseases
• Vitamin D insufficiency as a potential culprit in critical COVID-19 patients
• Vitamin D insufficiency is prevalent in severe COVID-19
• Vitamin D Levels and COVID-19 Susceptibility: Is there any Correlation?
• Vitamin D Levels Associated with Covid-19 Infection Risk
• Vitamin D supplementation to prevent acute respiratory tract infections: systematic review and meta-analysis of individual participant data
• Vitamin D Supplementation: A Potential Approach for Coronavirus/COVID-19 Therapeutics?

Bottom Line:

The findings overwhelmingly suggest that vitamin D is a legitimate option to consider—especially in today’s climate. Want to know how much to take? Check out Back-to-School Supplements.
