Taking vitamin C DOES reduce the risk of a cold

Taking vitamin C to ward off a cold only helps if you exercise regularly, new research suggests.
Finnish researchers have found necking drinks rich in vitamin C - such such as orange juice - makes no difference to couch potatoes.
But in people who work out, vitamin C can halve the risk and even help get rid of the sniffles.  Scientists from the University of Helsinki embarked on a series of studies involving more than 11,000 people to work out the benefits of Vitamin C, found in many vegetables and fruits, such as oranges, strawberries and kiwis.
They gave groups of volunteers, including Swiss school children, marathon runners, teenage competitive swimmers and Canadian soldiers, a dose of the vitamin and then assessed its impact on their health.
