COVID from Home - Vitamin D, Zinc, Quercetin | Home Care for COVID

This video will discuss why zinc, quercetin, vitamin C and D, and n-acetyl cysteine and melatonin have been suggested as potential prophylaxis and even treatment for early symptoms of COVID.

Vitamin D and COVID

Right now, for early COVID infections, it is mostly supportive therapies just like for any common colds: bed rest, drinking plenty of fluids, aspirin and acetaminophen, cough, and cold syrups.

Zinc is an essential mineral that has been thought to improve immune function, cardiovascular health, control blood sugar, slow macular degeneration, and fight acne. Zinc is found in oysters, chicken, red meat, and fortified breakfast cereals. While whole food sources are the ways to get zinc, there is evidence that supplemental zinc can aid your immune system.

Research has shown that oral zinc formulations may shorten the duration of common cold symptoms, especially due to rhinovirus directly inhibiting viral replication. In addition, your body requires zinc to develop and activate T-cells, and decreased zinc levels have been associated with depressed immune function.

Quercetin is a plant pigment that is believed to have anti-carcinogenic, anti-inflammatory, antiviral activities, and inhibition of pro-inflammatory mediators. It is also an ionophore meaning it creates a channel in the cell to allow zinc in.

Vitamin C exerts its antiviral properties by supporting lymphocyte activity, increasing the production of interferon-α, modulating cytokines, reducing inflammation,

Glutathione also acts as a free radical scavenger in the body. It has been suggested that elderly adults have decreased glutathione levels, leaving them susceptible to COVID inflammation oxidative stress.

N-acetylcysteine (NAC) is a precursor of glutathione, described as “the master antioxidant,” Some studies show that NAC can increase glutathione levels. For example, an FDA-approved inhaled version of NAC called Mucomyst, which we used to decrease mucus's viscosity in patients in the hospital.

Melatonin exerts regulatory actions on the immune system. It directly enhances the immune response by improving the proliferation and maturation of natural killing cells, T and B lymphocytes, granulocytes, and monocytes in the bone marrow and other tissues.

Besides sleep disorders, melatonin has been used to treat delirium, atherosclerosis, respiratory diseases, and viral infections. In regards to viral infections, melatonin has anti-inflammatory, anti-oxidant, and immunomodulating properties.
