## What is Vitamin C (Ascorbic Acid)?

Vitamin C, also known as ascorbic acid, is one of the most popular and widely consumed supplements in Nigeria. Walk into any pharmacy in Lagos, Abuja, Port Harcourt, or Kano and you will find multiple brands of Vitamin C prominently displayed on the shelves. It is a water-soluble vitamin that the body cannot produce on its own, meaning it must be obtained through diet or supplementation. While citrus fruits like oranges and lemons, as well as local fruits such as guava, pawpaw, and garden eggs, are rich natural sources of Vitamin C, many Nigerians prefer the convenience and reliability of tablet or chewable supplement forms, particularly during the harmattan season when dry, dusty weather increases susceptibility to colds and respiratory infections.

Vitamin C gained even greater prominence in Nigeria following the COVID-19 pandemic, when demand for immune-boosting supplements surged dramatically across the country. Pharmacies in Idumota, Onitsha Main Market, and Ariaria Market in Aba reported massive increases in Vitamin C sales as Nigerians sought ways to strengthen their immune defences. The vitamin functions as a powerful antioxidant, protecting cells from damage caused by free radicals. It also plays a crucial role in the production of collagen, a protein essential for skin health, wound healing, and the maintenance of cartilage, bones, and teeth. Many Nigerian women also take Vitamin C for its skin-brightening benefits, making it a popular supplement in the beauty and wellness community.

Vitamin C is listed on the World Health Organisation's List of Essential Medicines, underscoring its importance in global healthcare. In Nigeria, it is available without a prescription and can be purchased from licensed pharmacies, patent medicine stores, and reputable online health stores. It comes in several forms including standard tablets, chewable tablets (popular with children and adults who dislike swallowing pills), effervescent tablets that dissolve in water, and syrups for younger children. Popular Nigerian brands include Emzor Vitamin C, which is manufactured locally and widely trusted, as well as imported brands like Mason Natural and Vitabiotics. Nature's Field, a proudly Nigerian supplement brand, also offers a well-regarded Vitamin C product that is widely available across the country.

## What is Vitamin C (Ascorbic Acid) used for?

- Boosting the immune system and supporting the body's natural defence against infections, particularly during the harmattan season and rainy season when colds and flu are common
- Prevention and reduction of the severity and duration of common cold symptoms
- Promoting healthy, glowing skin through collagen production — widely used by Nigerian women for skin brightening and anti-ageing benefits
- Enhancing the absorption of iron from plant-based foods and iron supplements, making it an important companion to ferrous sulfate treatment for anaemia
- Supporting wound healing and tissue repair after injuries or surgery
- Acting as a powerful antioxidant to protect the body's cells from oxidative stress and damage caused by free radicals

## Dosage

Always follow a doctor's or pharmacist's instructions; this is general reference information.

- Adults: The recommended daily intake for adults is 65mg to 90mg, but therapeutic doses commonly used in Nigeria range from 250mg to 1000mg daily. For immune support, 500mg to 1000mg daily is commonly taken. Do not exceed 2000mg per day as this may cause digestive discomfort.
- Children: Children aged 1-3 years: 15mg daily. Children aged 4-8 years: 25mg daily. Children aged 9-13 years: 45mg daily. Chewable tablets or syrup formulations are preferred for children. Always follow the dosage instructions on the specific product packaging or consult a pharmacist.
- Elderly: Standard adult doses of 500mg to 1000mg daily are generally safe for elderly individuals. Those with kidney problems should consult a doctor before taking high doses, as excessive Vitamin C can increase the risk of kidney stones in susceptible individuals.

Vitamin C is best taken with food to minimise stomach upset. Since it is water-soluble, the body excretes excess amounts through urine, so taking very high doses provides no additional benefit. For maximum immune benefit, take Vitamin C consistently rather than only when you feel unwell. If you are taking it to enhance iron absorption, take it at the same time as your iron supplement.

## Side effects

Common: Stomach upset or mild abdominal cramps, especially when taken on an empty stomach or at high doses; Nausea and occasional diarrhoea at doses above 1000mg; Heartburn or acid reflux in individuals with sensitive stomachs.

Serious (seek medical help immediately): Kidney stones with prolonged use of very high doses (above 2000mg daily), particularly in individuals with a history of kidney stones; Iron overload in people with haemochromatosis (a condition causing excessive iron absorption) when Vitamin C is taken in high doses; Severe allergic reaction (extremely rare) — symptoms include rash, swelling of the face or throat, and difficulty breathing.

When to see a doctor: See a doctor if you experience persistent stomach pain, blood in your urine, signs of kidney stones (severe flank pain, painful urination), or any allergic reaction such as skin rash, itching, or swelling. If you have a pre-existing kidney condition or are on regular medication, consult your doctor before starting high-dose Vitamin C supplementation.

## Warnings

Do not take if: Individuals with a history of kidney stones should avoid high-dose Vitamin C supplementation (above 1000mg daily) without medical supervision; People with haemochromatosis or other iron overload conditions should use Vitamin C cautiously as it enhances iron absorption; Those with glucose-6-phosphate dehydrogenase (G6PD) deficiency should consult a doctor before taking high doses of Vitamin C.

Interactions: Warfarin and other blood thinners — high-dose Vitamin C may reduce the effectiveness of warfarin; inform your doctor if you are on anticoagulant therapy; Aluminium-containing antacids — Vitamin C can increase aluminium absorption, which may be harmful for people with kidney problems; Chemotherapy drugs — some oncologists advise against high-dose antioxidants during cancer treatment; consult your oncologist; Statins and niacin — Vitamin C may reduce the effectiveness of some cholesterol-lowering drug combinations; Iron supplements — Vitamin C increases iron absorption, which is beneficial for anaemia treatment but may be problematic in iron overload conditions.

Pregnancy & breastfeeding: Vitamin C is generally safe during pregnancy and breastfeeding at recommended doses (up to 1000mg daily). It is commonly taken by pregnant Nigerian women alongside folic acid and iron supplements as part of routine antenatal care. Excessive doses above 2000mg daily should be avoided during pregnancy. Vitamin C passes into breast milk but is safe for breastfeeding mothers at standard doses. Always consult your antenatal healthcare provider for personalised guidance.

## FAQs

### Can Vitamin C prevent malaria?

No, Vitamin C does not prevent or treat malaria. Malaria is caused by Plasmodium parasites transmitted through the bite of infected Anopheles mosquitoes, and it requires specific antimalarial medications such as artemisinin-based combination therapies (ACTs) for treatment. However, Vitamin C can support your overall immune system and may help your body recover faster when you are unwell, including during a malaria episode. The best ways to prevent malaria remain sleeping under insecticide-treated nets, using mosquito repellents, and taking prescribed antimalarial prophylaxis when recommended. Do not rely on Vitamin C as a substitute for proper malaria prevention or treatment.

### What is the correct dosage of Vitamin C for adults in Nigeria?

The recommended daily allowance for Vitamin C is about 90mg for adult men and 75mg for adult women. However, for immune support — which is the most common reason Nigerians take Vitamin C — doses of 500mg to 1000mg daily are widely used and considered safe. During the harmattan season or when you feel a cold coming on, many pharmacists in Nigeria recommend taking 1000mg daily for a short period. Do not exceed 2000mg per day, as this can cause stomach upset, diarrhoea, and may increase the risk of kidney stones over time. For best results, take your Vitamin C with food and stay well hydrated.

### Is it safe to take Vitamin C every day?

Yes, it is generally safe to take Vitamin C daily at recommended doses (up to 1000mg per day for adults). Since Vitamin C is a water-soluble vitamin, your body does not store excess amounts — any surplus is simply excreted in your urine. Many Nigerians take Vitamin C daily as part of their wellness routine, particularly during the harmattan and rainy seasons when colds and infections are more common. However, consistently taking very high doses (above 2000mg daily) for extended periods is not advisable as it may increase the risk of kidney stones in susceptible individuals. If you eat a balanced diet rich in fruits and vegetables, you may not need to supplement daily, but a moderate daily dose of 250mg to 500mg is a reasonable choice for most people.
