Vitamin D plays a major roll in cellular antigen and immune responses. Deficiencies in Vitamin D are high in the general human population and requires attention to amend.

B cells, T cells, and antigen presenting cells are major catalysts and players in immune function and have special receptors for Vitamin D which helps regulate both innate (non-specific) and adaptive immune (specific) antibody responses. These specific and non-specific immunes responses are paramount. Deficiency of Vitamin D is associated with compromised immune function and higher risk of infection. Respiratory tract infections (inflammation and mucus) such as tuberculosis and influenza are highly associated with Vitamin D deficiency.

The British Medical Journal (BMJ) released a meta-analysis study which concluded that Vitamin D is safe and effective in protecting against respiratory tract infections and in fact states it is a necessary and essential vitamin. Vitamin D can induce Cathelicidins and Defensins. Cathelicidins and Defensins are antimicrobial peptides (AMPs) that provide protection against viruses and other micro-organisms. In respiratory conditions we have inflammation which leads to injury of the lung tissue hence why ICU’s are not ideal as they cause pressure trauma to the tissue. Cathelicidins and Defensins reduce inflammation and promote tissue repair improving respiratory track conditions.

Many studies were and are still being conducted to investigate the effects of Vitamin D in the prevention and treatment of the Common Cold (Coronavirus), Flu and other respiratory conditions with various names.

The Journal of Clinical Endocrinology & Metabolism published an article which found that Vitamin D deficiency was found in 82.2 % of respiratory cases, including SARS-CoV-2, and that blood levels of Vitamin D were lower in hospitalised patients compared to those that did not need hospitalisation and recovered.

This highlights clearly that these respiratory cases and patients had underlying conditions revolving around vitamin and mineral deficiencies causing mucus and inflammation resulting in hospitalisation.

Prevention is always better than the cure.

Deficiency of zinc can lead to serious dysfunctions of the immune system because zinc can also act as an antioxidant.

Zinc is essential for the activity of a series of enzymes instrumental to rapid immune response for the clearance of opportunistic pathogens.

Research has proven that zinc accelerates recovery time during the Common Cold (the symptoms) which can be causes by Coronaviruses (the cleaner).

Quercetin is a potent antioxidant with the ability to improve memory and help reduce oxidative stress and inflammation in the body. Quercetin is used to reduce symptoms of allergies, to improve cardiovascular health, to improve blood sugar regulation, reduce inflammation, and some studies suggests its cancer fighting properties.

Quercetin is a zinc ionophore that help both the absorption of zinc into the body as well as the absorption of zinc into cells dependent upon it for enzyme production. Additionally, as a potent antioxidant, Quercetin is an equally potent anti-bacterial and antiviral nutrient that is particularly essential for respiratory and cardiovascular infections.

Although more research is necessary for specific information about Quercetin and SARS-CoV-2, there is strong evidence showing the potential benefits of this nutrient. Quercetin is recommended to be supplemented in combination with Vitamin C for better absorption and improved synergistic function.

Prevention is always better than the cure.

L-arginine is an amino acid which helps build protein in the body and it has been studied for its effects enhancing cardiovascular health, its antioxidant properties, and immune boosting benefits.

One of the main arguments for L-arginine’s therapeutic effects focused on its ability to convert to nitric oxide. Nitric oxide is a naturally occurring compound which plays a role in the health of blood vessels improving blood flow. Nitric oxide improves the symptoms of conditions such as asthma and it is used as a medical intervention for acute lung infection.

Nitric oxide is being suggested by researchers as another treatment for SARS-CoV-2 based on previously done studies which reported success in helping during the coronavirus virus epidemic of 2003 (SARS). Researchers also mention the anti-viral effects of nitric oxide could be beneficial in helping treat SARS-CoV-2.
