coronavirus outbreak has seen a huge spike in people buying vitamin supplements, with vitamin c and Zinc emerging two of the top supplements in demand.Typically, in any viral infection, the body's defence mechanism is to produce white blood cells (WBCs) to fight against the infection.
Zinc and vitamin c reduces the level of chemicals called cytokines that are harmful to the body and are produced in the body during infections. Zinc helps increase the production of these infection-fighting WBCs and T cells.Vitamin C, while providing overall immunity, is the most effective against respiratory based illnesses. Lack of vitamin c is also the most common nutritional deficiency.
There have been reports of people believing in vitamin c to be a cure for coronavirus, which is certainly not true. While vitamin c helps boost immunity, it is basic hygiene, good food habits and physical activities that help build immunity, rather than just the supplements. Pre-existing medical conditions like uncontrolled diabetes, uncontrolled High bp, uncontrolled cholesterol, etc too result in low immunity and these supplements should be seen as agents that help the body withstand or fight infections and not coronavirus itself.
