Why Vitamin C is Important for a Healthy Immune System

Why Vitamin C is Important for a Healthy Immune SystemDuring my college days, one of my friends Ramya was so obsessed with citrus fruits that she used to sneak oranges and sweet lime in a box and used to have them in between class lectures. Besides this, there was another very interesting fact about her that when most of the class would be down with flu or a cough and cold, she would rarely get sick during the entire changing weather. With the blocked nose, incessant sneezing and bad cough we all used to be very jealous of this girl who would hardly fall sick.

Years after, I got to know from one of my cousins studying medical how important Vitamin C is for a healthy immune system. Today, let us know in details about Vitamin C and its many benefits.

But before that, it is important to know that our body does not have the ability to produce Vitamin C. It gets the nutrient from external sources in the form of foods. A daily dose of Vitamin C is very essential as it is a water-soluble type of Vitamin and gets excreted easily. Researchers have found out that people affected by common diseases are low on Vitamin C compared to healthy individuals.

 5 Health Benefits and Sources of Vitamin C


Why Vitamin C is important?

People suffering from a cough and cold have often been seen having a Vitamin C deficiency in their body along with a weakened immune system. A chronic cold condition can lead to pneumonia and other respiratory infections in children and older adults.

Vitamin C not just affects the development of the immune system but it also slows down the innate system we are born with, the adaptive immune system that develops right from childhood and adulthood. It also poses a negative impact on the immune cells that are meant to defend your body against invaders like bacteria and virus and also prevents the antibodies production to fight infections.

As the body’s immune system gets affected due to deficiency of Vitamin C, we get more vulnerable to infections and once they invade the body, the inability to fight these infections lead to even serious health conditions. This is even serious in adults because they grow old they tend to suffer from an old-age condition called immunosenescence that increases the risk of more infections and diseases.


If you have a sufficient amount of Vitamin C in your body, it aids in the absorption of all the nutrients from the food we intake. As more and more nutrients get absorbed by our system, it makes our body healthy and strong so that it is able to fight against unwanted bacterial and viral infections.
