Zinc supplementation protects from cold and cough

Minerals are inorganic substances, which the body cannot produce on its own. Although the amounts needed of some minerals are smaller than a grain of sand, they are crucial to the growth and production of bones, teeth, hair, blood, nerves, skin and hormones.

There are two types of minerals, major and trace minerals, classified by how much the body needs. Major minerals are grouped together because the body needs relatively significant amounts of them.

Trace minerals are needed in smaller amounts. These trace minerals include iron, copper, zinc, manganese, chromium, selenium and iodine.

How Zinc supplementation protects from cold and cough

Let welcome the cold season and here you go down with cold and flu.  Zinc helps in protecting from the cold in two ways:

  1. Zinc works on the immune system by activating T-lymphocytes. 

Studies have shown people with low zinc supplementation have reduced lymphocyte proliferation and other adverse effects on immunity which can be corrected by zinc supplementation.

  1. Works on Common Cold

We usually suffer from cold because of the virus called rhinovirus, which thrives and multiplies in the nasal and throat passage. Several studies have indicated that zinc supplementation taken in the form of lozenges reduces the length of a cold by one day when taken within 24 hours of the first signs and symptoms of a cold.

 In a randomized, double-blind, placebo-controlled clinical trial, 50 subjects (within 24 hours of developing the common cold) took a zinc acetate lozenge (13.3 mg zinc) or placebo every 2–3 wakeful hours. Compared with placebo, the zinc lozenges significantly reduced the duration of cold symptoms (a cough, nasal discharge, and muscle aches)
