How does it Affect Immunity?

A Potent Antioxidant

Free radicals are harmful molecules that can damage the cells in the human body. Vitamin C protects the cells by donating an electron to these free radicals. Thus, Vitamin C (a potent water-soluble antioxidant) stabilizes the free radicals and prevents further damage to the immune cells. Beets, Blueberries, Broccoli, Flaxseed oil, Green Tea, Garlic, Ginger, Seaweed, Spinach, are some antioxidant-rich foods that help boost your Immune System.

Decreases Inflammation

As Vitamin C has the capability of stabilizing the free radicals that damage the cells and tissues, it lessens the scope of inflammation. Besides, it might prove beneficial in lowering C-reactive proteins.

Boosts Collagen Production

Collagen is the most abundant protein and major connective tissue in our body. It is part of tendons, ligaments, skin, muscles, and bones or you may say, a platform providing structure as well as strength.

Usually, collagen production is boosted by Hyaluronic acid that is naturally present in our body but this tends to decrease with age. Further, the intake of sugar and refined carbs along with exposure to ultraviolet radiation (sunlight) causes damage to the collagen. However, Vitamin C has the potential to increase this acid level and collagen, thus proving beneficial for the body.

Promotes Wound Healing

Apart from the many health benefits spoken of, Vitamin C plays a major role when it comes to healing a wound. It assists the better absorption of iron in the body. Also, it cross-links the collagen molecules and enhances tissue strength. Moreover, it promotes the collagen genes to synthesize collagen for better and quicker healing.

Boosts immune cells that can swallow harmful bacteria and other particles

Vitamin C boosts the production of Phagocytes (a type of WBC). These immune cells ingest the bacteria and other harmful particles along with dead or dying cells to protect the body.

Promotes the growth of immune cell types that increases your circulating antibodies

Vitamin C promotes the production of Lymphocytes (a type of WBC). These immune cells recognize foreign microorganisms/substances through the receptor molecules on their surface and also remove them.

Benefits during a Cold

Intake of Vitamin C indicates a reduction in the symptoms of a cold. Thus, it lays an impact by reducing the severity and also in decreasing the recovery time. There are some other natural home remedies for cold that can help you recover faster.

Important tips-

  • It is advisable to get more Vitamin C from your diet rather than opting for supplements.
  • Vitamin C is water-soluble and never stored by the body thus, a regular intake of foods rich with Vitamin C is suggested rather than supplements.


Overall, vitamin C exerts beneficial effects on cellular functions of the body. It can prevent and treat respiratory infections as well as help boost the immune system.
