Vitamin C for Colds? The 50-Year-Old Myth Debunked

Vitamin C is essential for health. It protects cells, helps absorb iron, and makes collagen. But can it stop or shorten a cold? Research shows it cannot. People who take vitamin C get just as many colds as those who do not. This widespread belief persists largely because of one scientist, says Professor Daniel M Davis of Imperial College London. "The idea that high doses will stop a cold is a myth," he states. The myth began over 50 years ago. It was heavily promoted by the famous chemist Linus Pauling. His strong advocacy made vitamin C a popular cold remedy, despite evidence to the contrary. While vital for overall health, vitamin C is not a cold cure.
