However, regular vitamin C supplements had several benefits, including:
Reduced cold severity: They reduced the symptoms of a cold, making it less severe.
Reduced cold duration: Supplements decreased recovery time by 8% in adults and 14% in children, on average.
However, it’s less known that vitamin C is also highly concentrated in immune cells and quickly depleted during an infection. In fact, a vitamin C deficiency significantly weakens the immune system and increases the risk of infections.
Other Nutrients and Foods That May Help
There is no cure for the common cold. However, some foods and nutrients can help the body recover. In the past, people have used various foods to reduce their symptoms.
Few of these are scientifically proven to work, but some are backed by evidence.
Flavonoids: These are antioxidants found in fruits and vegetables. Studies suggest that flavonoid supplements may reduce the risk of infections in the lungs, throat and nose by 33%, on average.
While taking supplements may be necessary to reach the high vitamin C intake required to improve colds, make sure not to go overboard. That’s because too much vitamin C has some adverse side effects.
To meet your basic nutrient requirements, whole foods are generally a better idea. Good examples of healthy foods that are high in vitamin C include oranges, kale and red bell peppers."
