Nutraceuticals are the blended products containing both nutritional as well as medicinal values. These are specifically processed to satisfy dietary requirements with preventive health benefits. The COVID-19 pandemic outbreak has been very affirmative towards nutraceutical and dietary supplements as boosting the immune system is one of the major challenges for us now. Wide approaches towards therapeutic values led to know us about protective properties of nutraceuticals and functional food as the calories taken in should be less than calories given out. Despite a lack of scientific records, compelling evidence from the literature shows that some nutraceuticals (which include omega‑3 enriched supplements, topmost functional foods like gingerols and shogaols in ginger, β‑glucans, probiotics, herbs and high intake of vitamin and mineral supplements has shown an excellent effect in reducing the risk of influenza and COVID-19 like infections). Nutraceuticals have poor oral bio availability which lowers the efficiency as health promoting agents. Engineered Nano (EN) particles in this frame of reference have shown stability in food and Gastro Intestinal Therapeutic System (GITs). In the present review article, the benefits of these natural compounds may not only modulate the immunity of a prone population, however may also pave the manner in the direction of the development of drugs which can be used to treat COVID‑19. However, here we have discussed various advantages of nutraceuticals in this devastating global pandemic but still the path of attentive clinical trials and experimental studies are required to validate their efficacy, in order to counteract the ongoing increase in the number of cases of COVID-19. The current times have cast a dark shadow yet we strive to continue through strong immunities built by healthy nutraceuticals. So, always keep vigilance on your bite and sip.
