Vitamin B group
Vitamin B group is famous for its individual function. Riboflavin is essential for cell energy metabolisms against (MERS‐CoV)[17]. Niacin can kill Staphylococcus aureus and inhibit the neutrophil infiltration with a physically powerful anti‐inflammatory activity in ventilator-induced lung injury[18]. Pyridoxine is well known for the immune system due to the protein metabolism function[19]. Folic acid can enhance the immune system by white blood cell production that acts as soldiers for body defiance. Cobalamin remains the ratio (CD4+/CD8+) balances and facilitates (T-lymphocytes cells) production in a normal range[20]. Consequently, the Vitamin B group might be used as COVID‐19 treatment.
