Does prune juice help lower blood pressure?

Yes, prune juice has been shown to help lower blood pressure. Studies have found that drinking prune juice regularly can significantly reduce systolic blood pressure, by an average of 2–3 mmHg. This effect is thought to be due to the high potassium content of prune juice, which helps to regulate blood pressure and reduce the effects of sodium. The natural sorbitol content in prunes may also contribute to the blood pressure-lowering effect.
