Nutrients and Covid: They Still Matter

Entering another year of Covid-19 being a part of everyday life, it bears repeating that vitamins, minerals, and other nutrients can still make a difference in bolstering the resilience of the immune system.

This review finds good evidence that deficiencies of vitamins and minerals including A, C, D, E, zinc, and selenium can be a factor in the severity of Covid-19 symptoms and recovery from the illness. Omega-3 fatty acids also have immune defending effects in part, by strengthening the structure of cellular walls, and making it tougher for viruses to gain a foothold.

While it may be tempting to let things on the personal health front slide a bit, just out of plain fatigue from staying vigilant for the past couple of years, it is vitally important to remain focused on keeping yourself and your family well. One of the best ways to ensure that your immune system is strong is to keep a healthy diet, free of inflammation-causing refined carbs that can throw your health out of balance. Getting plenty of restorative, healthy sleep is a must as well. But adding supplemental nutrients, including A, C, D3, E, zinc, selenium, and omega-3s may make a noticeable difference in keeping you from dealing with the worst effects of Covid-19 or other viruses.

Shakoor H, Feehan J, Al Dhaheri AS, Ali HI, Platat C, Ismail LC, Apostolopoulos V, Stojanovska L. Immune-boosting role of vitamins D, C, E, zinc, selenium and omega-3 fatty acids: Could they help against COVID-19? Maturitas. 2021 Jan;143:1-9.

The world is currently in the grips of the coronavirus disease (COVID-19) pandemic, caused by the SARS-CoV-2 virus, which has mutated to allow human-to-human spread. Infection can cause fever, dry cough, fatigue, severe pneumonia, respiratory distress syndrome and in some instances death. COVID-19 affects the immune system by producing a systemic inflammatory response, or cytokine release syndrome. Patients with COVID-19 have shown a high level of pro-inflammatory cytokines and chemokines. There are currently no effective anti-SARS-CoV-2 viral drugs or vaccines. COVID-19 disproportionately affects the elderly, both directly, and through a number of significant age-related comorbidities. Undoubtedly, nutrition is a key determinant of maintaining good health. Key dietary components such as vitamins C, D, E, zinc, selenium and the omega 3 fatty acids have well-established immunomodulatory effects, with benefits in infectious disease. Some of these nutrients have also been shown to have a potential role in the management of COVID-19. In this paper, evidence surrounding the role of these dietary components in immunity as well as their specific effect in COVID-19 patients are discussed. In addition, how supplementation of these nutrients may be used as therapeutic modalities potentially to decrease the morbidity and mortality rates of patients with COVID-19 is discussed.
