Researchers from the United Kingdom, Sweden and the United States emphasized in a recent study the importance of using nutritional supplements to combat the Corona virus. COVID-19 Corona , And published on the pre-print site medRxiv * That micronutrient is like vitamins C And D Zinc is known to boost the immune system and reduce the risk of developing a respiratory infection.

Nutritional supplement and the immune system

Since the Coronavirus is a respiratory infection, these nutrients have been prescribed and counseled by health care professionals and since the beginning of the epidemic, the authors of this study wrote that these nutrients can be obtained from diets and nutritional supplements, taken alone or as part of A multi-nutrient or multivitamin tablet.

Several other supplements are also known to benefit health and the immune system, and researchers write that these include omega-3 fatty acids (“fish oil”), probiotics, and plant isolates like garlic.

Purpose of the study

This study was an application-based longitudinal community survey. I tested participants who had signed up for a symptom-based application COVID-19 (Implementation COVID Symptom Study).

The use of regular nutritional supplements was examined and included “probiotics, garlic, omega-3 fatty acids (” fish oils “), multivitamins, vitamin D, vitamin C or zinc.

Overall, the researchers found that:

  • Probiotics reduced the risk of infection with corona by 14%
  • Omega-3 fatty acids reduced the risk of developing corona by 12%
  • The multivitamins reduced the risk of developing corona by 13%
  • Vitamin D reduced the risk of infection by 9%.

Supplements of vitamin C, zinc, or garlic did not significantly reduce the incidence of Corona infection.

Researchers have defined the protective roles of nutritional supplements as follows:

  • Vitamin D – Immune cells express vitamin D receptors and thus play a role in the function of antigen-presenting cells, T cells and B cells.
  • Multivitamins – their ingredients contain antioxidant properties, and studies have shown that they may reduce the risk of developing a respiratory infection
  • Omega-3 fatty acids – play a role in the function of T cells and B cells and are anti-inflammatory.
  • Probiotics can alter the gut microbiota and may generate antiviral metabolites that strengthen the host immune system.
  • Zinc, Vitamin C, and Garlic – Studies have shown that they may play a role in reducing symptoms, but similar results were not shown in this study.

This study revealed a significant protective effect of probiotics, omega-3 fatty acid, and vitamin or D supplementation against SARS infection. The team wrote, “No clear benefits for men were observed, nor any effect of vitamin C, garlic, or zinc for men or women.”
