How 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.

2.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)

GNC Ultra Zinc Lozenges are scientifically designed to support a healthy immune system and provide antioxidant protection.

Each lozenge is blister packed to be portable and easy to use. Echinacea and Zinc - Key ingredients that help support natural resistance. Vitamins A and C - Essential antioxidant vitamins that protect cells against the damage caused by free radicals.

Strengthen your Immunity with Multivitamins

What do you usually do every time you’re down with the common cold? Pop in a few antibiotics, or maybe let the disease run its course. But, have you ever wondered why do you get sick time after time?

The core of your health issues is not the viral or bacterial infections, but your weakened immune system that reduces your body’s capacity to fight against the disease-causing microorganisms. More often than not, your immune functions are weakened due to nutritional deficiencies. Thus, the best way to protect your body against illness is to provide it with adequate micronutrients through a well-balanced diet. Or, you can take a multivitamin supplement every day to fill the nutritional gaps in your diet and boost your immune functions to prevent getting sick and keep yourself healthy all year round.

Strengthen your Immunity with Multivitamins

Here’s how different vitamins and minerals can help you strengthen your immunity:

Vitamin A 

This fat-soluble vitamin protects your body against viral infections, common cold, flu, etc. by enhancing the functions of T cells, B cells, cytokines, white blood cells and skin cells to stop the bacteria and germs from entering your system in the first place.

Vitamin C

This powerful antioxidant stimulates the production and functions of white blood cells, which are responsible for fighting off the bacteria and viruses that enter the body, to boost your immunity, and reduce the severity of cold, flu, fever and throat infections and prevent allergies.

Vitamin D 

Besides calcium absorption and bone development, D vitamin plays a pivotal role in immune support by creating a protein that can destroy pathogenic cells causing cough, fever, flu and respiratory tract infections. It is also known to reduce the risk of diabetes, cardiovascular and autoimmune diseases, and even cancer.

Strengthen your Immunity with Multivitamins

Vitamin E 

Just like A, C and D vitamins, Vitamin E acts as an efficient immunity booster. This antioxidant has immunosuppressive properties that can help in treating auto-immune diseases and reducing the risk of health issues caused due to the harmful effects of free radicals and oxidative stress on the body.

Vitamin B Complex

B vitamins don’t just give your body the energy it needs by breaking down digestive proteins, but also help fight the disease-causing bacteria and viruses by increasing the number of white blood cells in your body and synthesizing the antibodies that strengthen your immune system.


Deficiency of zinc can affect the functioning of the immune cells. Thus, taking a multivitamin rich in zinc can help improve your immune system, and get relief from cold and sore throat and heal wounds.

Strengthen your Immunity with Multivitamins


When taken in combination with Vitamin E, this immunity-boosting mineral can help keep the disease-causing pathogens at bay to prevent the risk of cancer and increase the life of AIDS patients.


This trace mineral regulates the level of nutrients such as Vitamin D and zinc in your body, which is why it is essential for your immune system to function properly.

You can get these multivitamins and more here. While these multivitamins can help in optimizing the functions of your immune system, lifestyle changes like healthy eating, regular exercise, quality sleep and avoiding alcohol and smoking, go a long way in ensuring your long-term wellness.
