Pomegranates are a good source of vitamin C, vitamin K, and potassium, as well as several other key nutrients. In fact, eating one pomegranate gives you about 28 mg of vitamin C, which is almost 50 percent of your daily recommended intake (DRI). This fruit also provides about 666 mg of potassium, or 19 percent of your DRI
In some studies, pomegranates show potential to be effective in preventing prostate, breast, lung, and colon cancers.
