Vitamin C won't save you from a cold after all

Well it seems the old standby Vitamin C isn't all it's cracked up to be when it comes to curing the sniffles and misery caused by the common cold. A 60 year study concluded recently in Australia (that's one long study) that found taking high doses of Vitamin C on a daily basis only slightly reduces the risk of getting a cold in the first place (8% for adults and 13.8% for kids) and doesn't shorten the length of colds at all once they've been caught. So is it worth it to take a big Vitamin C pill every single day just to average 11 days of illness a year instead of 12? That extra day of wellness is pretty special (I hate colds!) but I also hate taking pills -- decisions decisions!
