The debate over the magic qualities of vitaminCseems to be ending in its favour. Mark Levine of the National Institute of Health's Clinical Center in Bethesda in the US, conducted a study and found that 200 milligrams a day of vitamin C appears to be an ideal daily amount. This is more than three times the 60 milligrams per day dose advised by physicians presently, Since five servings of fruits and vegetables a day will easily provide 200 milligrams a day of vitamin C, researchers ruled out the need for taking vitamin C supplements.
