The Truth About Ascorbic Acid: Antioxidant Power, Vitamin C, and Its Effects on the Body
What Is Ascorbic Acid?
Ascorbic acid is a water-soluble vitamin that cannot be stored in the body and must be consumed on a regular basis.
In addition to dissolving in water, ascorbic acid is sensitive to high temperatures and is fully lost when boiled in water.
What Exactly Is Ascorbic Acid Used For?
Ascorbic acid is a powerful antioxidant that helps protect polyunsaturated fats from oxidation, both directly and indirectly by inhibiting vitamin E oxidation.
It also contributes in the synthesis of collagen, several metabolic reactions, and the biosynthesis of amino acids, hormones, and acid. It also helps to maintain healthy blood vessels, bones, and teeth.
Ascorbic acid improves immune system barriers and helps prevent cancers, particularly stomach cancer, by blocking the synthesis of carcinogenic chemicals. Furthermore, its participation is critical in neutralizing free radicals.
There are numerous proposed applications, ranging from the treatment of scurvy to those of the common cold. Ascorbic acid has been proposed to treat gum problems, acne, bronchitis, gastric ulcers, dysentery, bladder and prostate infections, depression, Alzheimer’s, and various kinds of dementia.
However, it appears that the EFSA (the European Food Safety Authority) has not accepted claims that explain these proposed uses; in fact, the Authority has rejected authorization to claims that ascorbic acid would provide relief for the mouth and throat.
On the other hand, EFSA has accepted claims that vitamin C enhances iron absorption and leads to:
- Maintaining normal immune system functioning during and after physical activity
- Collagen synthesis for normal bones, teeth, cartilage, gums, and skin
- Energy metabolism
- Nervous system functioning
- Physiological functions
- Oxidative stress protection
- Fatigue reduction
- Vitamin E regeneration
Ascorbic Acid Warnings and Potential Contraindications
Ascorbic acid may interact with aluminum, estrogens, fluphenazine, chemotherapy, protease inhibitors, statins, niacin, warfarin, paracetamol, choline and magnesium trisalicylate, nicardipine, nifedipine, and salsalate.
Its oral intake is considered safe when the recommended dosages are followed, but it may be contraindicated, particularly in the presence of tumors, diabetes, hematological diseases, kidney stones, heart attack, G6PD deficiency, Mediterranean anemia, and smoking or chewing tobacco.
If in doubt, consult your doctor.
