Common Use

Ascorbic acid, also known as Vitamin C, is an essential organic compound found in various fruits and vegetables. Being water-soluble, it cannot be stored in the body, requiring daily replenishment to prevent deficiency. Vitamin C acts as a potent antioxidant and plays a crucial role in regulating oxidation-reduction processes. It aids in collagen and procollagen synthesis, metabolism of folic acid and iron, and the production of steroid hormones and catecholamines.

Additionally, ascorbic acid helps regulate blood clotting, normalizes capillary permeability, supports hemopoiesis, and exhibits anti-inflammatory and antiallergic properties. It protects the body from stress-related damage, enhances tissue repair, boosts immunity, and reduces the impact of allergens. Research suggests Vitamin C may have a role in cancer prevention, as cancer patients often exhibit symptoms of vitamin deficiency.

Dosage and Direction

Take Vitamin C as directed by your healthcare provider. The recommended daily doses are as follows:

• Infants under 1 year: 30-35 mg
• Children 1-3 years: 40 mg
• Children 4-10 years: 45 mg
• Pregnant and breastfeeding women: 75-90 mg
• Smokers: 100 mg

Precautions

Consult your doctor if you have any of the following conditions: kidney disease, history of kidney stones, liver disease (particularly cirrhosis), glucose-6-phosphate dehydrogenase (G6PD) deficiency, or if you are pregnant, planning pregnancy, or breastfeeding. Ascorbic acid may increase the risk of kidney damage when combined with other nephrotoxic medications. Inform your doctor if you are undergoing chemotherapy, taking medications for bowel disorders, organ transplant rejection, antiviral drugs, painkillers, anti-arthritis medications, or injected antibiotics, as dosage adjustments may be necessary.

Discontinue use and seek medical attention if you experience severe lower back or side pain, bloody or painful urination, persistent diarrhea, or fainting.

Contraindications

Ascorbic acid should not be used by individuals with hypersensitivity to its components.

Possible Side Effects

Contact your doctor if you experience any of the following severe or bothersome side effects:

• Intense lower back or side pain
• Bloody or painful urination
• Severe or persistent diarrhea
• Feeling faint or lightheaded

Drug Interactions

Ascorbic acid may interact with other medications. Concurrent use with aspirin can irritate the stomach, potentially leading to ulcers, and may increase urinary excretion of Vitamin C, reducing its blood levels. Ascorbic acid can also elevate aluminum levels, increasing toxicity risk, so avoid aluminum-containing medications. High doses of Vitamin C may impair the body's ability to absorb Vitamin B12 from food or supplements.

Missed Dose

If you miss a dose, skip it and continue with the next scheduled dose. Do not double the dose to make up for the missed one.

Overdose

Overdosing on ascorbic acid is unlikely to cause life-threatening symptoms, but diarrhea is a common side effect. Contact your doctor if you suspect an overdose.

Storage

Store ascorbic acid at room temperature, between 15-30°C (59-86°F).
