What is vitamin C

Vitamin C is a water-soluble organic compound classified as a vitamin. Chemically it is known as L-ascorbic acid. The human body is not able to synthesize sufficient amounts of this nutrient, which means it must be obtained through the diet. From a biochemical perspective, vitamin C participates in a variety of enzymatic reactions and metabolic processes within the body.


Biological role of vitamin C

Vitamin C contributes to the normal function of the immune system and helps reduce tiredness and fatigue. It also contributes to normal collagen formation, which is an important component of connective tissue. For this reason, vitamin C is widely described in nutrition science as one of the key micronutrients present in the human diet.


Scientific background and research

Vitamin C has been extensively studied for many decades. Scientific publications on ascorbic acid examine its chemical structure, metabolism, bioavailability, and role in biological processes. Research on vitamin C spans fields such as biochemistry, nutrition science, medicine, and food science, contributing to a broader understanding of its role in human nutrition.

Where Vitamin C occurs naturally?

Vitamin C occurs naturally mainly in plant-based foods. Major dietary sources include citrus fruits, bell peppers, blackcurrants, strawberries, and kiwi, as well as vegetables such as broccoli and cabbage. The vitamin C content of foods is widely documented in nutritional databases and food composition tables.
