Vitamin C has long been recognized as an effective vitamin for fighting colds. Chemist Linus Pauling concluded many years ago that the vitamin can cure colds. Fast forward to 2014, and vitamin C is still very very popular.
But a new review claims that zinc is more powerful in preventing colds. Reseachers conducted random tests on children in Iran. One group was asked to consume zinc sulphate supplements on a daily basis, while the second group was given a placebo pill. They later discovered that the ones who consumed zinc had lesser colds in a year.
On the other hand, researchers also tested vitamin C on more than 11,000 people. Surprisingly, they found no meaningful benefit in the vitamin.
They also found out that general hand washing helps fight colds and prevent other illnesses. “The best evidence for the prevention of the common cold supports hand-washing and possibly the use of zinc supplements,” said Michael Allan of the Department of Family Medicine at the University of Alberta.
Interestingly, the researchers discovered that other widely-accepted cold remedies such as ginseng, vapor rubs, and cough medicines were not very beneficial as well. Even using antibiotics to cure colds were found to cause more harm than good.
