Not only fruits but also vegetables. The fruit and veggies that contains the highest amounts of vitamin C are green peppers, of course citrus and juices, strawberry, tomatoes, brocoli, and green leafy veggies. They don't only contain this vitamins but some other vitamins and minerals. :) xx

When our body cells use oxygen, they naturally produce by-products called 'free radicals' which can cause damage. Antioxidants act as "free radical scavengers" and help to prevent and repair damage done by these free radicals.
There are very many antioxidants, including the vitamins A, C and E. They are abundant in beans, grain products, fruits and vegetables. Fruits and vegetables with bright colours also tend to be high in antioxidants - lutein in some of the yellow pigments found in corn; orange carotenoids in cantaloupe, butternut squash and mango; red from lycopene in tomatoes and watermelon, and flavonoids in purple and blue berries (grapes, blueberries, blackcurrants and so on). Lignan is found in many grains such as flax seed, oatmeal, barley and rye.
Lemons, along with all citrus fruits, are a good source of Vitamin C but green vegetables and many other fruits such as blackcurrants and rose hips also contain large amounts. It is important to eat a balanced diet and not to give too much importance to any one nutrient. Too much of some vitamins can make you ill!

Zeaxanthin is one of the carotenoid group (mentioned above): http://www.vitaminstuff.com/zeaxanthin.html
I have to say that I had no intention of giving an exhaustive listing of all antioxidants or to write a complete treatise on the subject! Anyone who wants that sort of detail will no doubt find it on the Internet (starting here: http://en.wikipedia.org/wiki/Antioxidant , perhaps) or in a dietary text book. I was merely concerned with pointing out that Vitamin C is only one of many antioxidants and that the body needs some or all of them in a balanced diet to remain healthy.
Not all antioxidants are automatically 'a good thing'. Many have risks associated with taking an excess. Overdosing with Vitamin C, for example, is likely to cause diarrhoea and the commonest antioxidant found in the body, uric acid, is, when in high concentrations, associated with gout.

To reach the levels of Vitamin C in your body to cause diarrhoea takes a lot of vitamin C, as in taking it a supplemental form.
Vitamin C is water soluble, the body will take what it needs and the rest will be excreted in the urine. And Vitamin C does not last long in the blood so for curing a cold large amounts must be taken but not at one time. Better divide in small doses throughout the day to keep the levels of ascorbic acid high.
Also if taking vitamin C in a supplemental form its best to eat some fruits or veggies along with taking the supplement in order to get the other substances/chemicals that work together with the vitamin C to have a stronger effect in the body.
From the Supplemental forms of Vitamin C, the best is liposomal vitamin C, straight into the cells. :) Maybe not better than taking it as an IV but as far as practicality goes Liposomal Vitamin C can be taken in many small doses throughout the day... On the other hand shooting it through IV while effective, not practical because you cannot be sitting in a chair 5-10 times a day putting needles in you :)
