Vitamin C, also known as ascorbic acid, is an antioxidant that is critical for a body’s normal growth and development as well the repair of tissue. It also helps your body absorb the iron needed for healthy red blood cells. Despite popular belief, vitamin C can’t reduce your chances of getting a cold but it can play a big role in supporting your immune function. There is, however, some evidence that suggests taking this vitamin supplement on a regular basis may shorten colds a little or reduce the severity of symptoms.
Since your body is not able to produce or store vitamin C, it’s important to incorporate foods with this vitamin into your daily diet. Some of the richest sources of vitamin C are citrus fruits like lemons, limes, and oranges; leafy green vegetables, including spinach and kale; red and green peppers; and broccoli, tomatoes, potatoes, squash, Brussels sprouts, cauliflower, and cabbage. You’ll get the most vitamins out of these foods if they are eaten raw or just lightly cooked.
