Essential vitamin: Vitamin c is required by our bodies as we do not make it with our biochemistry. However, with our 1st world diet, deficiency would be extremely rare. There has been hype about mega amounts of vit c as a supplement to ward off colds and other illnesses. This has not been borne out by any proper testing. Products such as 'emergenc' are a waste of money.
