Vitamin C To Fight Viruses — Does It Actually Work?

What is vitamin C and what does it do

Vitamin C, also known as ascorbic acid is a water-soluble vitamin essential to the body. (1) It is an antioxidant commonly known to strengthen the immune system and may reduce the risk of infections. (2,3) Besides that, vitamin C also helps in collagen formation, wound healing, and improves iron absorption. (1)


Vitamin C and immune health

Vitamin C plays an important role in promoting a healthy immune system through supporting the production of white blood cells and antibodies. (4) Low levels of vitamin C can increase your risk of catching colds and you may take a longer time to recover as well.


Studies have shown that daily vitamin C supplementation is associated with a decrease of common cold incidences (3) and reduction of duration and severity of common cold symptoms. (5)


What affects vitamin C levels in the body

Smokers tend to have lower vitamin C levels as the chemicals in the cigarette take up vitamin C in the body. (6) This is because vitamin C is an antioxidant which reduces inflammation by protecting the body against damage from the chemicals of the cigarette. Besides smoking, drinking alcohol also depletes vitamin C in the body. (7)


Individuals with certain health and medical conditions such as diabetes (6), heart disease (6), stroke (6), and chronic kidney disease (8) also tend to have lower vitamin C status. Vitamin C levels also decrease during infections such as Covid-19 virus infection. (9) These conditions cause inflammation in the body and thus, depletes vitamin C levels in the body.

    The variant of the D vitamin that is formed under your skin is recognized as vitamin D3, or cholecalciferol.
    This D vitamin is established when the ultraviolet in the sunlight reacts
    with a type of cholesterol that is available under your skin naturally.
