Vitamin C is the absolute star of cold and flu season. And for good reason — the antioxidant has some special superpowers that work to make you healthier.
The vitamin stimulates the production of white blood cells, which in turn protect the body against infections and foreign invaders. Research shows that people who took it every day were half as likely as others to get a cold; and when they did get sick, they got over their symptoms 8% faster, according to a review of several studies by the University of Helsinki.
The most famous source of the powerful antioxidant is oranges. And while citrus fruit does contain vitamin C, it's not the only way to get a dose. Here, the foods you can start adding to your diet today in order to give your immune system a healthy bump.
