Pomegranate

The heart-healthy pomegranate is a great source of nitric oxide. Pomegranate seeds are high in antioxidants, which help to increase the formation of nitric oxide and protect it from damage. Pomegranate juice was shown to preserve nitric oxide from oxidative damage while also enhancing its activity in a test tube research.

Pomegranate juice and pomegranate fruit extract were found to enhance levels of nitric oxide synthase and boost nitrate levels in the blood in another animal study. Pomegranate, which is strong in antioxidants, has been shown in human and animal tests to improve blood flow, which might be especially helpful in treating conditions like high blood pressure and erectile dysfunction. Other human and animal research has found that the antioxidants in pomegranates can help blood flow more freely, lowering the risk of heart disease.
