Vitamin C Day

Vitamin C Day is an American holiday dedicated to vitamin C. Perhaps if you ask people what their most popular vitamin is, there is a 90% chance they will say vitamin C. It is tightly associated with citrus fruits and the season of colds because of its anti-cold character formed in society. The holiday is celebrated annually on April 4.


The history of Vitamin C Day is only a few years old. The holiday was created in 2019, when SkinCeuticals, a brand that produces a line of skin care products, came up with a similar initiative. It is dedicated not only to the beneficial properties of the vitamin, but also to the successful creation of a way to deliver antioxidants from this vitamin into the skin, developed by the company’s experts.

Vitamin C was discovered in 1928 by chemist A. Szent-Györgyi, and four years later scientists were able to determine the cause of scurvy – a lack of ascorbic acid (as this vitamin is also called). Scurvy is a disease of the gums. As early as the 17th century, sailors used citrus fruits to prevent it, even though they knew nothing about the role of vitamin C.

Interesting facts

  • The average dose of vitamin C for an adult is 90 mg. It is found not only in citrus fruits, but also in potatoes, cabbage, tomatoes, sweet peppers, and rose hips.
  • Vitamin C (like E) promotes the production of interferons (proteins secreted by the body in response to virus invasion), which makes it an important component in treating colds and strengthening immunity.
  • A typical orange practically contains a daily dose of vitamin C (75 grams on average).

How to celebrate

Eat more citrus fruits on this day. Take ascorbic acid more often during colds to speed recovery, but avoid overdosing (taking more than 100 mg daily for long periods of time). Purchase SkinCeuticals skin care products.

Spread the word about the holiday on social media. Ask other users if they consume enough vitamin C per day.
