Ascorbic Acid: The Primary Scientific Name
The most prominent alternative name for vitamin C is ascorbic acid. This is the scientific name for the pure chemical compound. The term "ascorbic" literally means "no scurvy," which highlights its historical significance in preventing the once-deadly disease. When you see "ascorbic acid" listed on the ingredients of a fortified food or supplement, it is essentially the same active nutrient as vitamin C.
Albert Szent-Györgyi, a Hungarian biochemist, played a critical role in its discovery and identification in the 1930s. He isolated a substance he initially called "hexuronic acid" from various plant and animal sources, eventually confirming its identity as the anti-scurvy factor and renaming it ascorbic acid.
Other Common Names for Vitamin C
Beyond its core chemical name, you will find several other terms for vitamin C, particularly in the health and supplement industry. These variations are often related to their form or function.
- Antiscorbutic Vitamin: This is the historical name for vitamin C, referencing its ability to prevent scurvy, a disease caused by severe deficiency.
- Mineral Ascorbates: These are buffered forms of vitamin C, created by reacting ascorbic acid with a mineral. They are less acidic and are often used by individuals who experience stomach discomfort with regular ascorbic acid supplements.
- Sodium Ascorbate: A popular buffered form that is sodium-based, providing both vitamin C and sodium.
- Calcium Ascorbate: Another mineral ascorbate that provides a dose of calcium along with the vitamin C.
- Dehydroascorbic Acid (DHA): This is the oxidized form of vitamin C. The body can recycle DHA back into ascorbic acid, maintaining an adequate supply.
The Crucial Role of Vitamin C in the Body
Regardless of what else it is known as, the functions of vitamin C are critical for maintaining overall health. It acts as a powerful antioxidant, protects cells from damage, and is involved in numerous biological processes.
As an Antioxidant Vitamin C's potent antioxidant activity is one of its most important functions. It neutralizes reactive oxygen species (ROS), or free radicals, that can cause significant damage to cells, DNA, and proteins. This protective function helps mitigate oxidative stress and inflammation, factors that contribute to many chronic diseases.
As a Cofactor for Enzyme Production Vitamin C also acts as a cofactor for several key enzymes in the body. Its roles include:
- Collagen Synthesis: Vitamin C is necessary for the hydroxylation of proline and lysine, two amino acids crucial for synthesizing and stabilizing collagen, the main structural protein in connective tissues. This is why vitamin C is vital for wound healing and healthy skin, bones, and blood vessels.
- L-Carnitine Synthesis: It is required for the production of L-carnitine, a molecule that helps transport fatty acids into mitochondria for energy.
- Iron Absorption: It significantly enhances the absorption of non-heme iron from plant-based foods.
- Neurotransmitter Synthesis: It plays a role in the creation of specific neurotransmitters, like norepinephrine.
Comparing Forms of Vitamin C
| Aspect | Ascorbic Acid | Mineral Ascorbates (e.g., Sodium Ascorbate) | 
|---|---|---|
| Acidity | High; pH of 2.2–2.5 | Buffered; less acidic and gentler on the stomach | 
| Stomach Tolerance | Can cause gastrointestinal upset in some individuals. | A good option for those with a sensitive stomach. | 
| Additional Nutrients | Contains only vitamin C. | Provides vitamin C plus a mineral, such as sodium or calcium. | 
| Use | Standard supplement, food additive (E300), and research. | Oral supplements for easier digestion. | 
The Versatility of Vitamin C
Beyond its name, vitamin C is a remarkably versatile and essential nutrient. Its various forms are used for different applications, from standard oral supplements to specialized topical skincare products that utilize fat-soluble derivatives like ascorbyl palmitate for enhanced absorption. The diverse range of chemical names and forms reflect the many ways this single vitamin can be harnessed for health and wellness.

Conclusion: More Than a Common Name
In conclusion, what else is vitamin C known as? Primarily, its chemical name, ascorbic acid, reveals its core identity. However, the nutrient is also recognized by historical names like the "antiscorbutic vitamin" and various derivatives such as sodium and calcium ascorbate, which offer unique benefits in supplement form. Understanding these different titles provides a clearer picture of this powerful antioxidant's critical role in maintaining bodily health, from supporting collagen production and immune function to protecting cells from damage.
