Since we cannot produce vitamin C in the body, humans are able to obtain the vital nutrient through consumption of dietary sources, such as fruits and vegetables.

While there are many benefits of consuming vitamin C to the whole body, the immune system is what we will focus on this post.

Vitamin C may also enhance the function of various white blood cells, resulting in the destruction of microbes.
