Vitamin C is probably the best known of all the vitamin family and every single one of our fruit smoothies contain this incredible little vitamin. It's structure was discovered in 1933 at the University of Birmingham by a clever chap called Walter Haworth. It's a powerful anti-oxidant which means it can prevent cell damage from free radicals.

Most plants can make vitamin C from glucose but humans, primates, guinea-pigs and some birds can’t. This means that we have to get it from the food we eat.

The most concentrated sources of vitamin C are:

• berries
• guava
• strawberries
• citrus fruits

How much do you need?

The recommended daily amount (RDA) for vitamin C is 60mg. The RDA is the level of nutrients needed to help our bodies prevent deficiency, disease and maintain normal nutrition. So, 60mg of vitamin C is the amount our bodies need to help with all that stuff and stop us catching things like scurvy (the disease that old sailors lacking in vitamin C where their wounds wouldn’t heal properly).

Vitamin C participates in many everyday processes, including absorption of iron and skin healing. There is some evidence to suggest that for optimum health it could be that higher levels are needed.

Your body is clever enough to know how much it needs. As vitamin C is water soluble if you have more than you need your body it gets rid of the extra vitamin when you go for a pee
