Insight about the common cold and vitamin C (Ascorbic Acid)

Despite exhaustive research across the world, there is still no strong evidence to prove that vitamin C helps prevent the common cold.

Some studies have shown that taking large doses of vitamin C (more than 1,000 mg per day) continuously or when you first develop cold symptoms, may ease some of the symptoms and the duration — on average, making it about half a day shorter. It does not prevent you catching a cold.

Large doses may cause nausea, abdominal cramps, headaches, fatigue, kidney stones and diarrhoea. It may also interfere with your body’s ability to process (metabolise) other nutrients, for example, it could lead to dangerously raised levels of iron.

Excessive amounts of vitamin C in the body can also interfere with medical tests, such as diabetes tests, giving a false result.

Cutting and heating foods changes vitamin C and makes it less effective. So it helps to eat fruits and vegetables raw, or lightly cooked, and don’t cut them too long before eating them. You should be able to get all the vitamin C you need from your diet.

Adults need about 45 mg of vitamin C per day and any excess amount is excreted.
