Vitamin supplement (Water-soluble vitamin)
Last reviewed July 2026
Who is this for?
Vitamin C (also called ascorbic acid) is a vitamin supplement that helps your body fight infections, heal wounds faster, and absorb iron from the food you eat.
Acts as a reducing agent and electron donor in enzymatic hydroxylation reactions, facilitating collagen synthesis, carnitine formation, and catecholamine metabolism while enhancing non-heme iron absorption through reduction of ferric to ferrous iron. Serves as a cofactor for cytochrome P450 enzymes and antioxidant systems, scavenging reactive oxygen species and regenerating other antioxidants including vitamin E and glutathione.

For general supplementation, take 1 tablet (100mg to 500mg) once or twice daily, with or after food. You can take it with water or chew it if it is a chewable tablet like Remgvite Vitamin C Chewable Tablet. For treating a deficiency, your doctor may recommend up to 1000mg daily, but do not exceed this without medical advice.
If you miss a dose, just take it when you remember. If it is almost time for your next dose, skip the missed one and continue as normal. No need to double up — Vitamin C is not the type of drug where missing one dose will cause problems.
Buy from reputable pharmacies — avoid roadside sellers or open market vitamin tablets that may have been exposed to sun and heat, reducing their potency. Do not take extremely high doses thinking it will cure infections like malaria or typhoid — Vitamin C supports your immune system but is not a treatment for these diseases. Check the expiry date before buying, as expired Vitamin C loses its effectiveness.
If you are taking iron tablets (like ferrous sulfate for blood tonic), Vitamin C increases iron absorption — this can be helpful but take them together only if your doctor says so. If you are on blood-thinning drugs like warfarin, high doses of Vitamin C may reduce their effect. Avoid taking very high doses of Vitamin C at the same time as aluminium-containing antacids (like some ulcer drugs) as it can increase aluminium absorption.

Is it safe to take Vitamin with your other drugs?
Vitamin C is generally safe during pregnancy and breastfeeding at normal recommended doses (up to 85-120mg daily), but avoid taking megadoses — consult your doctor or pharmacist before using high-dose supplements.
Store in a cool, dry place away from direct sunlight and heat — Nigerian weather can damage vitamins quickly. Keep the container tightly closed to protect from humidity and moisture. Always keep out of reach of children, especially chewable tablets that may look like sweets.
