The Benefits of Vitamin D: Hint: COVID-19 is One of Them

Scientific studies have found that vitamin D can help promote a healthy immune system and may protect against respiratory conditions. Given this, it comes as no surprise that research has found a relationship between vitamin D and severity of symptoms and mortality rates related to the coronavirus.

“We believe, that we can advise Vitamin D supplementation to protect against SARS-CoV2 infection.”

Recent research examining the role of Vitamin D in the prevention of Coronavirus Disease 2019 infection and mortality have highlighted the importance of this nutrient. They cite strong associations between deficiency of this vital nutrient and mortality in the face of the coronavirus disease. In their review of over 11,000 people from 14 different countries, they found that vitamin D supplementation reduced the risk of acute respiratory infection by at least 12%. Additionally, countries with sufficient sunlight for adequate vitamin D levels are seeing lower mortality rates than countries with more widespread vitamin D deficiency due to lack of sunlight and supplementation.

In addition to immune system and respiratory health, Vitamin D plays a number of other critical roles in the human body, including:

  • Building and maintaining healthy bones and teeth

  • Supporting brain and nervous system health

  • Regulating insulin levels and supporting the management of diabetes

  • influencing the expression of genes involved in the development of cancer

  • Supporting lung function and cardiovascular healthy

  • Promoting calcium absorption

  • May decrease risk of seasonal flu

  • May reduce symptoms of anxiety and depression

  • May suppress appetite and boost weight loss

  • Can help support restful sleep

  • May naturally boost testosterone

  • May improve athletic performance and energy

  • May help prevent the development of asthma, eczema, and other allergic diseases in children

  • May promote healthy pregnancy and delivery

As we age, it is more difficult for our bodies to synthesize vitamin D as efficiently. Insufficient exposure to sunlight, poor diet, obesity, IBS, ad other factors may also lead to deficiency. Given the many vital roles that this nutrient plays in our health, it is especially important to make sure you and your family are getting adequate levels.
