Yes, Vitamin C Has a Scientific Name
Vitamin C is widely recognized, but its scientific name is ascorbic acid. This name originated from its ability to prevent scurvy, with 'ascorbic' meaning 'no scurvy'.
The Discovery and Significance of Ascorbic Acid
Scurvy prevention with citrus fruits was noted in the 18th century. Albert Szent-Györgyi isolated 'hexuronic acid' in the 1920s, which he and Joseph L. Svirbely identified as vitamin C in 1932. This led to Szent-Györgyi's 1937 Nobel Prize and allowed mass production, greatly reducing scurvy globally, though it still affects some groups. Humans cannot produce vitamin C due to lacking the L-gulonolactone oxidase enzyme.
Understanding the Functions of Ascorbic Acid
Ascorbic acid is a water-soluble antioxidant that protects cells. It is vital for:
- Collagen Synthesis: Essential for making collagen, crucial for tissues like skin and bones.
- Iron Absorption: Helps absorb non-heme iron from plants.
- Immune Function: Supports white blood cells.
- Wound Healing: Important for tissue repair.
Ascorbic Acid in Your Diet vs. Supplements
Available in foods and supplements, bioavailability is similar.
Dietary vs. Supplemental Vitamin C
| Feature | Dietary Vitamin C (Ascorbic Acid) | Supplemental Vitamin C (Ascorbic Acid) |
|---|---|---|
| Source | Fruits and vegetables. | Synthetic forms. |
| Bioavailability | High. | Equivalent to natural sources. |
| Cost | Can be less expensive with smart choices. | Varies, can be cost-effective for high doses. |
| Usage | General health. | Deficiencies or high-dose needs. |
| Gastrointestinal Impact | Less likely to cause upset at normal levels. | High doses may cause issues. |
| Stability | Destroyed by heat/storage. | Provides stable dose. |
Whole foods offer broader nutrients.
Conclusion
Vitamin C's name is ascorbic acid, reflecting its role in preventing scurvy. It is a key antioxidant needed for immune health, collagen, and iron absorption, obtained from diet or supplements.
Potential Side Effects and Precautions
Excessive vitamin C (over 2,000 mg/day) can cause issues like diarrhea. The body excretes excess. Be cautious with conditions like hemochromatosis or during chemotherapy. High intake might raise kidney stone risk in some. A balanced diet is often sufficient.

What is the RDA for Ascorbic Acid?
RDA varies. Adults (19+) need 90 mg/day (men) and 75 mg/day (women). Pregnant women need 85 mg/day, lactating 120 mg/day. Smokers need an extra 35 mg/day. These are easily met through a diet with fruits and vegetables.
Sources of Vitamin C
