Viral infections, including lower respiratory tract infections (LRTIs) and COVID-19, pose significant health risks worldwide. The immune system plays a critical role in combating these infections. Current research underscores the importance of micronutrients in enhancing immune function. This article reviews the impact of specific micronutrients on the immune system and discusses the potential of supplementation as a supportive strategy against viral infections.[1]
Importance of Micronutrients in Immune Function
Vitamins and Omega-3 Fatty Acids
Studies have highlighted the crucial roles of vitamins A, C, D, and omega-3 fatty acids in modulating the immune response. These nutrients are key in supporting various aspects of both innate and adaptive immunity.
Zinc
Zinc is another micronutrient identified as vital for immune function. Its deficiency can lead to weakened immune response, increasing susceptibility to infections.
Supplementation as a Supportive Measure
Supplementation with these micronutrients is seen as a safe, cost-effective way to bolster the immune system. It is recommended to supplement these nutrients in addition to maintaining a balanced diet, adhering to the upper safety limits set by health authorities.
While individual micronutrients contribute to immune health, their synergistic effects require further investigation. Current research suggests that combinations of these nutrients might enhance the overall immune response more effectively.
It is crucial to note that supplementation is not a cure or guaranteed prevention for infections. Instead, it may help reduce symptoms and facilitate recovery from viral infections.
Conclusion
Implementing an optimal nutrition strategy, including a balanced diet and appropriate supplementation of key micronutrients, can be a beneficial approach to reducing the burden of infectious diseases worldwide, including COVID-19. However, this should be viewed as part of a broader strategy that includes other public health measures.

(PMID 33092041) [PubMed] [DOI] [Full text] Viral infections are a leading cause of morbidity and mortality worldwide, and the importance of public health practices including handwashing and vaccinations in reducing their spread is well established. Furthermore, it is well known that proper nutrition can help support optimal immune function, reducing the impact of infections. Several vitamins and trace elements play an important role in supporting the cells of the immune system, thus increasing the resistance to infections. Other nutrients, such as omega-3 fatty acids, help sustain optimal function of the immune system. The main aim of this manuscript is to discuss of the potential role of micronutrients supplementation in supporting immunity, particularly against respiratory virus infections. Literature analysis showed that in vitro and observational studies, and clinical trials, highlight the important role of vitamins A, C, and D, omega-3 fatty acids, and zinc in modulating the immune response. Supplementation with vitamins, omega 3 fatty acids and zinc appears to be a safe and low-cost way to support optimal function of the immune system, with the potential to reduce the risk and consequences of infection, including viral respiratory infections. Supplementation should be in addition to a healthy diet and fall within recommended upper safety limits set by scientific expert bodies. Therefore, implementing an optimal nutrition, with micronutrients and omega-3 fatty acids supplementation, might be a cost-effective, underestimated strategy to help reduce the burden of infectious diseases worldwide, including coronavirus disease 2019 (COVID-19).
