**15. Conclusion and future perspective**

Besides building and maintaining a stronger immune system, vitamin B can actually prevent or alleviate the symptoms of COVID-19 and / or treat infectious diseases with SARSCoV2. Inadequate nutritional conditions are much more susceptible to infections. Therefore, a balanced diet is needed to enhance immunity. Complementary or safe and cost-effective treatments are needed to reverse abnormal activation of the immune system that can lead to cytokine storms and as an antiplatelet agent. An adequate intake of vitamins is essential for the normal functioning of the body and the boosting of the immune system. B vitamins help control the immune response by decreasing pro-inflammatory cytokines and inflammatory conditions, minimising respiratory and gastrointestinal disease, preventing hypercoagulability, and possibly improving outcomes and shortening the hospital stay for COVID-19 patients.
