Vitamin D Foods and Covid-19

    When news of a cluster of severe pneumonia cases in Wuhan, China was first reported to the World Health Organization on Dec31 2019, none of us would have expected the virus to spread so quickly throughout the world with Singapore confirming its first case of COVID on Jan23 2020. Things escalated quickly and a ministerial task force was formed to tackle all issues and problems pertaining to the coronavirus. The rest is history. There is one increasingly established scientific fact: The consumption of Vitamin D Foods in Covid-19 patients helps towards a faster recovery 1.

    In the battle against COVID-19, the world has made great strides. Right now, each and every one of us is learning to coexist with the virus and the onus is on everyone to take charge of their health by adequately equipping their bodies with the right and optimum nutrition to prevent, fight and control the effects of each infectious wave. The Omicron BA.5 wave, the most recent, is currently abating. However, it is important that everyone stays vigilant with the potential occurrence of more variants and waves as COVID-19 will remain with us for quite some time.

    Vitamin D Foods and COVID-19

    At MILESTONE, we truly believe that Foods with Vitamin D3 can play a significant role in combating COVID and as such offer the most innovative and holistic solutions that target inflammation within the body caused by the virus.

    Through large observational studies conducted in different parts of the world, it has been found that there is a connection between the levels of Vitamin D and the effects on COVID-19 2 3. A deficiency in Vitamin D has been observed in the following:

    • People who require hospitalization after contracting the virus.
    • People who are tested positive and take a considerably longer time to test negative.
    • People who are more elderly. This can be attributed to the fact that with age, the skin receptors become less effective in converting the UVB rays of the sun into Vitamin D, even with a minimum exposure of between 20 to 30 minutes daily.
    • People with darker skin tones. For those with darker skin tones, the melanin in the skin becomes a barrier for sunlight to penetrate through and prevents the smooth conversion of Vitamin D from cholesterol.

    The “Cytokine Storm” in people who experience COVID

    A cytokine storm is a type of immune system overreaction which can make illnesses like COVID-19 and even influenza lethal. Small proteins known as cytokines are generated by a variety of cells throughout the body and include immune system cells which coordinate the body’s defense against infection and thereby promote inflammation 4 5. The Greek words for cell (cyto) and movement (kinos) are where the word “cytokine” comes from. The body’s reaction to illness can occasionally go into overdrive so for instance, when SARS-CoV-2, the virus that caused the COVID-19 pandemic, infects the lungs, the immune system reacts by drawing immune cells to the area to fight the virus, which causes localized inflammation 6. However, in some patients, excessive or uncontrolled cytokine release results in the activation of additional immune cells which can result in hyperinflammation.

    In the event of a “cytokine storm”, elevating Vitamin D levels in the body can play a significant role in modulating the autoimmune response which could otherwise overwhelm bodily systems and result in possible symptoms which include the following:

    • Fever or chills
    • Persistent Cough
    • Shortness of breath or difficulty breathing
    • Fatigue
    • Muscle or body aches
    • Headache
    • Loss of taste or smell
    • Sore throat
    • Congestion or runny nose
    • Nausea or vomiting
    • Diarrhea

    With the intake of Functional Foods for Vitamin D3, we may be able to greatly reduce the severity of the above symptoms and strengthen the body’s immunity to cope with all kinds of viral attacks and bacterial infections. This is the reason that makes Vitamin D Foods an effective solution in COVID-19 cases.

    Dr. Ben Ng, an endocrinologist from Arden Endocrinology Specialist Clinic at Mount Elizabeth Novena Specialist Centre in Singapore mentioned that:

    Considering that it will benefit musculoskeletal health and may help with overall Covid-19 risk, I would encourage all patients who may be at risk of vitamin D deficiency to consider taking vitamin D replacement. Adding a daily dose of 400-1,000 units is extremely safe and unlikely to cause harm.
