The pomegranate is an exotic fruit that has been mentioned in literature as old as the Bible, but the juice of the pomegranate is more widely consumed than the fruit itself. Pomegranate juice contains a negligible amount of vitamin C, 0.2 mg in a 1 cup serving, which isn't even 1 percent of the recommended daily value. But it does contain other vitamins and minerals that are beneficial to overall health, according to the USDA National Nutrient Database.
The vitamin with the highest content in pomegranate juice is K. Best known for its ability to promote the proper clotting of blood, vitamin K is essential to health, as without it you could bleed to death. For some, however, the blood clots too easily and blood thinners are in order. If this is the case for you speak to your doctor before consuming foods high in vitamin K, such as pomegranate juice, as vitamin K may counteract the work of blood thinners. A 1-cup serving of bottled pomegranate juice contains 25.9 micrograms of vitamin K, or 32 percent of the recommended daily intake.
Pomegranate juice contains several B vitamins, the highest of which is folate. Also known as vitamin B9, folate plays a role in several vital bodily functions such as the production and maintenance of healthy DNA and the production of new blood cells. The NIH Office of Dietary Supplements states that folate is especially important to have in your body during times of rapid cell growth, such as pregnancy and the early childhood growing years. A 1-cup serving of pomegranate juice contains 59.8 micrograms of folate, or 15 percent of the RDI. Other B vitamins in the juice are pantothenic acid, B6, niacin, riboflavin and thiamin. All B vitamins play a role in the development of red blood cells and energy metabolism.
Pomegranate juice contains a trace amount of vitamin E in a 1-cup serving, with 0.9 mg or 5 percent of the RDI. The Linus Pauling Institute reports that the primary role of vitamin E is its action as an antioxidant vitamin. Antioxidants protect your cells from damage caused by free radicals, which are unstable molecules produced during oxidation. These free radicals can lead to cellular and DNA damage which may lead to serious chronic disease, including cancer.
Along with vitamin E, pomegranate juice contains other antioxidant compounds, such as tannins, that have a positive impact upon your overall health. According to a report in "Complementary Therapies in Clinical Practice," the antioxidants in pomegranate juice can prevent heart disease, lower blood pressure and counter physical and mental decline related to aging.
