National Vitamin C Day

Celebrated on 04/04/2026

Quick Fact

National Vitamin C Day is celebrated on April 4th each year, a date chosen to coincide with the birthday of vitamin C pioneer Dr. Albert Szent-Györgyi, who won the Nobel Prize in 1937 for discovering the vitamin. This day encourages people to boost their intake of citrus fruits and other vitamin C-rich foods to support immune health and prevent scurvy.

Origins and Establishment of National Vitamin C Day

National Vitamin C Day was established by the natural health and wellness community, with early origins tied to recognizing the importance of vitamin C in human nutrition. The date April 4th was chosen to honor Dr. Albert Szent-Györgyi, the Hungarian physiologist who first isolated vitamin C in 1932 and later won the Nobel Prize in Physiology or Medicine in 1937 for his discoveries related to biological combustion, with special reference to vitamin C and fumaric acid. The day was officially promoted by organizations like the Vitamin C Foundation and various health advocacy groups to raise awareness about the vitamin's benefits.

Evolution and Modern Commemoration

Initially observed through small health-focused events and educational campaigns, National Vitamin C Day has grown in popularity with the rise of social media and wellness trends. Today, it is celebrated by sharing recipes rich in vitamin C, promoting supplements, and highlighting the vitamin's role in collagen production, immune function, and antioxidant protection. Many health food stores and online retailers offer discounts on vitamin C products, while nutritionists and influencers post educational content about optimal intake and food sources.

Facts & General Observations

  • Scurvy, caused by vitamin C deficiency, was a major problem for sailors in the 18th century, leading to the British Navy's adoption of lime juice as a preventive measure, earning sailors the nickname "limeys."
  • Vitamin C is water-soluble, meaning the body does not store it, so regular intake through diet or supplements is necessary; the recommended daily allowance for adults is 75-90 mg.
  • A single medium orange provides about 70 mg of vitamin C, while a cup of raw broccoli offers 81 mg, and a cup of strawberries contains 89 mg.
