Prune juice is high in B vitamins, which play a role in metabolism, DNA and red blood cell production, and skin and eye health.

Furthermore, it’s widely used as a remedy for constipation, especially in older populations. Its fiber content appears to help soften stool and acts as a mild laxative.

It’s also a good source of antioxidants, such as vitamin C and phenolic compounds.

Though prune juice is a natural source of sugar, it’s best to limit your intake to a small glass per day or dilute it with water.
