Mega C (Ascorbic Acid)

Mega C (Ascorbic Acid) provides nutritional support and acts within the antioxidant and collagen‑synthesis pathways.

• Scurvy: helps prevent and treat vitamin C deficiency disease.
• General nutritional supplementation: contributes to normal immune function and overall health.
• Antioxidant support: assists in protecting cells from oxidative stress.

• Ascorbic Acid functions as a potent antioxidant and serves as a co‑factor for several enzymes involved in collagen synthesis, catecholamine production, and immune cell function. By donating electrons, it neutralises free radicals and supports the regeneration of other antioxidants, thereby maintaining cellular integrity and facilitating normal physiological processes.

Ascorbic Acid is generally well tolerated, but some users may experience mild adverse reactions.

Common Side Effects

• Gastrointestinal upset: nausea, abdominal cramps, or mild diarrhoea.
• Stomach discomfort: occasional heartburn or indigestion.
• Headache: transient mild headache in a small number of individuals.

Serious or Rare Side Effects

• Kidney stones: high doses may increase oxalate excretion, contributing to stone formation.
• Allergic reactions: rash, itching, or swelling of the face, lips, or tongue.
• Anaphylaxis: rare but severe systemic hypersensitivity requiring immediate medical attention.

When using Mega C, consider the following safety measures.

• Assess dietary intake: ensure supplementation is needed based on nutritional assessment.
• Monitor high‑dose use: prolonged intake of large amounts may increase risk of kidney stones.
• Avoid in known hypersensitivity: discontinue if allergic reactions occur.
• Caution in renal impairment: adjust use under medical supervision.
• Interact with iron supplements: avoid excessive combined dosing without guidance.
• Store at ambient temperature: keep in the original pack, protect from moisture and direct sunlight.

Ascorbic Acid can influence the absorption or effectiveness of several medicines.

Major Interactions (Avoid)

• Iron supplements: may increase iron absorption leading to overload.
• Aluminum‑containing antacids: can reduce vitamin C absorption.
• Certain chemotherapy agents (e.g., bortezomib): high‑dose vitamin C may diminish therapeutic effect.

Moderate Interactions (Monitor Closely)

• Oral contraceptives: may slightly reduce hormonal efficacy.
• Statins: potential increased risk of muscle toxicity.
• Diuretics: heightened risk of kidney stone formation when combined with high vitamin C intake.
