Vitamin C (Ascorbic Acid) — Detailed Explanation (History, Discovery, Uses, Deficiency, Sources, Advantages)
Introduction
Vitamin C (Ascorbic Acid), also known as Ascorbic Acid, is one of the most important vitamins required by the human body. It plays a major role in immunity, collagen formation, wound healing, antioxidant protection, and iron absorption. The discovery of Vitamin C is closely connected to the history of a deadly disease called Scurvy, which affected sailors for centuries.
Early History of Vitamin C
James Lind’s Experiment (1747) Long before scientists discovered vitamins, ancient civilizations noticed that certain fresh foods could cure bleeding and weakness-related illnesses.
- Ancient Egyptians, Greeks, and Romans used fresh fruits and vegetables for healing.
- Sailors during long sea voyages often suffered from scurvy because they lacked access to fresh food.
- During the 15th to 18th centuries, scurvy became one of the deadliest diseases among sailors.
What Was Scurvy?– Scurvy is a disease caused by severe Vitamin C deficiency.
Common Symptoms:
- Bleeding gums
- Loose teeth
- Weakness and fatigue
- Joint pain
- Skin bruises
- Poor wound healing
- Depression
- Death in severe cases
Millions of sailors died from scurvy before the actual cause was understood.
Discovery of Vitamin C
James Lind’s Experiment (1747)
- James Lind, a Scottish naval doctor, conducted one of the first controlled clinical experiments in medical history.
- In 1747, he selected sailors suffering from scurvy and divided them into groups with different treatments. One group received oranges and lemons daily.
- Result:
- The sailors who consumed citrus fruits recovered much faster than the others.
- This experiment proved that citrus fruits contained a substance capable of preventing and curing scurvy, although the exact nutrient was still unknown.
Albert Szent-Györgyi’s Discovery (1928–1932)
- Albert Szent-Gyorgyi was the scientist who successfully isolated Vitamin C.
- He extracted a substance called hexuronic acid from:
- Adrenal glands
Oranges
Cabbage
Paprika peppers - Later, scientists discovered that hexuronic acid was actually Vitamin C.
- The compound was renamed:-Ascorbic Acid
- meaning “anti-scurvy acid.”
Nobel Prize Achievement
- In 1937, Albert Szent-Gyorgyi received the Nobel Prize in Physiology or Medicine for his discoveries related to Vitamin C and biological oxidation processes.
Chemical Structure

Importance of Vitamin C in the Human Body
Vitamin C helps:
- Strengthen the immune system
- Produce collagen for skin and tissues
- Heal wounds faster
- Protect cells from oxidative damage
- Improve iron absorption
- Maintain healthy gums and bones
Humans cannot produce Vitamin C naturally inside the body, so it must be obtained through food or supplements.



Interesting Facts About Vitamin C
- Humans, monkeys, and guinea pigs cannot naturally produce Vitamin C.
- Vitamin C is destroyed by excessive heat during cooking.
- Sailors were once called “limeys” because British sailors consumed limes to prevent scurvy.
- Vitamin C is one of the most widely used dietary supplements in the world.
Conclusion
- The discovery of Vitamin C changed the history of medicine and nutrition. From deadly scurvy outbreaks among sailors to Nobel Prize-winning scientific research, Vitamin C became one of the most important discoveries in modern health science. Today, it remains essential for immunity, skin health, healing, and overall body function.
