Coronavirus: Scientific literature shows key role of micronutrients in optimal immune functioning

Better use of immunonutrition could benefit vulnerable groups during a pandemic such as COVID-19, according to a review of the scientific literature by two doctors published in the April 2020 issue of BMJ Nutrition, Prevention and Health.

There’s a wealth of evidence backing the significant roles played by all three in supporting a healthy immune system and improving our ability to combat respiratory illness, including flu and flu-like viral attacks.

NutraIngredients story published in May 2020 reviews the recent evidence on these key micronutrients and mounts a strong case for increasing your intake of all of them, whether by eating more of the foods that contain them or via straight-out supplementation.
