Vitamin C is a commonly used supplement and often reached for to try and bat away coughs and colds during the winter months.

It can not only help boost the immune system, but aid with the absorption of iron and works to maintain healthy skin, blood vessels, bones and cartilage.

According to Mayo Clinic, sources of vitamin C include berries, cantaloupe, tomatoes, peppers, potatoes, cabbage, Brussels sprouts, broccoli, spinach and citrus fruits, such as oranges.

Most people get enough vitamin C from their diet, yet people who smoke or are around secondhand smoke; have certain digestive conditions or types of can:cer or have a diet lacking in fruit and vegetables are more likely to be deficient.

So how much vitamin C should we be getting?

Mayo Clinic explain that in general, experts suggest that women get 75 mg of vitamin C a day and men get 90 mg.

They add: “Pregnant people should aim to get 85 mg a day. People who breastfeed their babies should try to get 120 mg a day. Children usually need less daily vitamin C than adults. The exact amount depends on their age.”
