Gonorrhea is an infection, which means that our immune system needs to be in top shape to combat it. One of the most accessible immune system-boosting vitamins is vitamin C, as it not only acts as an antioxidant, but also stimulates the production of white blood cells in the body. Furthermore, vitamin C is an important element of collagen, which is needed for regrowth and repair of cells and tissues following an injury or illness. Some of the best vitamin C-rich foods include leafy greens, pineapples, and other citrus fruits, along with berries, pepper, broccoli and peas.
