Zinc: Your Cold's Worst Enemy?

Taking zinc supplements this winter could help individuals recover from common colds more quickly. While zinc cannot prevent illness, studies indicate that daily intake can shorten symptom duration by several days.

Research has shown that zinc lozenges may reduce cold symptoms by two to three days. The mineral's effectiveness stems from its role in bolstering the immune system's germ-fighting capabilities.

Doctors advise starting zinc supplements at the first signs of a cold and taking them with protein or vitamin C for optimal absorption, while avoiding dairy and high-fiber foods.
