Abstract
There are some confines to the worldwide disease instigated by the novel coronavirus disease 2019 (COVID19), for now, a vaccine or treatment is available. According to SAGE, the Pfizer-BioNTech, COVID-19 mRNA vaccine is safe and effective. Vaccination is not recommended for certain populations due to contraindications, lack of availability, or inadequate data. Individuals with a background of grave allergies, pregnant women, and foreign travellers who are not part of a prioritized group, and children under the age of 16 are all cautioned against getting the vaccine. This necessitates the use of some alternatives that strengthen the immune system. The new therapies and medications provide our bodies with a window duration that aids in the creation of adaptive ion channels. The human immunity system is made up of various body organs and cells that work together with a symphony to defend the host from foreign particles such as viruses, bacteria, fungi, parasites, and so on. To synthesize various types of immune cells, our body needs a broad range of small amounts (vitamins and minerals) and large amounts (carbohydrate, protein, and fat) nutrients. Certain established prehistoric herbs that improve immunity include garlic, basil leaves, and black pepper. The following chapter includes a list of immunesupporting nutraceuticals (such as omega-3 fats, glucans, amino acids, probiotics, vitamins, and minerals) and plant’s secondary metabolites, as well as the impression of their supplementation in boosting the body’s immunity to make it able to combat COVID-19.
