Often called “the sunshine vitamin,” Vitamin D can be acquired from sunlight, diet, or supplements. Your doctor can help you determine whether you are getting enough or whether it makes sense to supplement (https://coromega.com/products/coromega-tropical-orange-d-30-count) your diet. The jury is still out regarding the effectiveness of vitamin D to ward off respiratory infection – but it’s connection to the human body’s immune function has been described as “undeniable.”  As we all search for solutions that will help us avoid COVID-19 infection (beyond masks, sanitizer and social distance) it is worth checking out and learning about possible ways to supplement our diet to find an edge. Vitamin D could be one more way to help maintain a strong immune system.

In this article, we have sourced and reviewed a number of articles and studies that may give you more information about the importance of Vitamin D to your body’s immune function. Links are attached.

  • Vitamin D and the immune system.
  • “It is now clear that vitamin D has important roles in addition to its classic effects on calcium and bone homeostasis. As the vitamin D receptor is expressed on immune cells (B cells, T cells and antigen presenting cells) and these immunologic cells are all are capable of synthesizing the active vitamin D metabolite, vitamin D has the capability of acting in an autocrine manner in a local immunologic milieu. Vitamin D can modulate the innate and adaptive immune responses. Deficiency in vitamin D is associated with increased autoimmunity as well as an increased susceptibility to infection. As immune cells in autoimmune diseases are responsive to the ameliorative effects of vitamin D, the beneficial effects of supplementing vitamin D deficient individuals with autoimmune disease may extend beyond the effects on bone and calcium homeostasis.”

  • Vitamin D deficiency more common among COVID-19 patients admitted to ICU.
  •  “Patients with COVID-19 requiring ICU admission are more likely to have vitamin D deficiency compared with those managed on medical wards, according to a retrospective study.”

  • Can Vitamin D lower your risk of COVID-19 infection?
  • “It’s important to note that there’s currently no cure for COVID-19 and no preventive measures other than physical distancing, also known as social distancing, and proper hygiene practices can protect you from developing this disease. That said, some research shows that having healthy levels of vitamin D, as well as taking a vitamin D supplement, can help keep your immune system healthy and may protect against respiratory illnesses in general. This article explains how vitamin D affects immune health and how supplementing with this nutrient may help protect against respiratory conditions.”

  • The immunological implication of the new vitamin D metabolism.
  • “Vitamin D is necessary for the proper functioning of your immune system, which is your body’s first line of defense against infection and disease. This vitamin plays a critical role in promoting immune response. It has both anti-inflammatory and immunoregulatory properties and is crucial for the activation of immune system defenses.”

  • Overwhelming Evidence Supports Vitamin D’s Immune Function Benefits.
  • “There is an ‘indisputable relation between Vitamin D and the ‘immune system’ says a new review that shows how avoiding Vitamin D deficiency has clear benefits for the immune system.”

  • Vitamin D Helps the Immune System During Cold and Flu Season.
  • “…[L] levels of vitamin D have been associated with worsening autoimmune diseases. Low levels of vitamin D are not the underlying cause of the autoimmune disease, but low levels of vitamin D can make autoimmune disease states worse. Low levels of vitamin D have also been associated with frequent infections. In 2009, the National Institute of Health warned that low vitamin D levels are associated with frequent colds and influenza. And so it appears that vitamin D helps keep the immune system balanced much like a gymnast walking on a balance beam.”

    1. Vitamin D is crucial for immune health -- make sure you're getting enough.

    “As the coronavirus pandemic continues to extend shutdowns, quarantines and social distancing measures -- many people are wondering how to keep themselves well. You know that social distancing, working from home and staying inside in general is one way to protect yourself -- but are there other measures you can take?

    Boosting your immune system is one of the best things you can do because it is your body's key defense when it comes to fighting a virus. Even if you are exposed to a virus, the coronavirus or others, if your immune system is strong, you have a better chance of not getting sick. Vitamin C is a popular choice for supporting immunity, but another key nutrient for your immune system is vitamin D. Once thought as the vitamin for strong bones, vitamin D actually does a lot more for your body -- including support your immune system.”

  • Can vitamin D help with symptoms of COVID-19? Possibly, it's key to helping your immune system function.
  • ‘It's been known for years that vitamin D is essential for maintaining healthy bones and teeth. Without it, bones can become thin, brittle or misshapen.

    Vitamin D also plays an important role in helping immune systems function. Low levels can lead to autoimmunity – when the immune system attacks healthy cells –  and increase the chance of infection.

    The immune system is like an army that prevents invaders, such as viruses and bacteria, from taking over the homeland – your body. It is composed of the innate and adaptive immune systems.’

    We encourage you to read up on Vitamin D and all other measures that people are employing to help them maintain strong immune systems during the pandemic.  At the very least it’s important to take all recommended steps to prevent infection – wear your mask (https://coromega.com/products/3-ply-disposable-face-mask?_pos=2&_sid=96e2900cd&_ss=r), wash/sanitize your hands (https://coromega.com/products/hand-sanitizer-packets?_pos=1&_sid=96e2900cd&_ss=r), maintain 6 feet of distance and follow the CDC guidelines (https://www.cdc.gov/coronavirus/2019-ncov/index.html).  We will get through this together, in health.
