Managing high blood pressure (hypertension) often starts with simple, daily habits, including being mindful about what you drink. Some vegetable and fruit juices can offer some benefits for your heart health, including by supporting healthier blood pressure.

Tomato juice may lower blood pressure, in part, because of its potassium content.
A small 2025 study from Indonesia studied men and women aged 40-70 years with high blood pressure. Participants drank one serving of tomato juice each morning for six weeks. By the end of the study, the tomato juice group saw a bigger drop in both systolic (top number) and diastolic (bottom number) blood pressure compared with the group that drank only water.

The same study found that cucumber juice may also help lower blood pressure. In the study, men and women drank one serving of cucumber juice each morning for six weeks. Their systolic and diastolic blood pressure dropped more than the group that only drank water.
Researchers think the potassium and water content in cucumbers may help the body release extra sodium and support healthier blood pressure over time.

Pomegranate juice may help lower blood pressure, especially in adults with hypertension. A large review of past studies found that in 11 of 17 reviewed trials, adults—mostly aged 20-60 years—showed small drops in systolic and diastolic blood pressure after drinking pomegranate juice for several weeks.

Some research shows that nitrate may help lower blood pressure. Nitrate, which is found in beetroot juice, is a nutrient your body converts to another nutrient, nitric oxide, which may help lower blood pressure.
A 2024 review combined results from 11 clinical trials that included about 350 adults who were 40-70 years old with hypertension. In many of these studies, people who drank nitrate-rich beetroot juice had a small drop in systolic blood pressure compared with those who drank nitrate-free juice, water, or had no drink.

Grapefruit is high in both water content and potassium and may help lower blood pressure when consumed with beetroot juice.
Researchers tested how beetroot juice, with or without grapefruit juice, affects blood pressure in healthy adults. On different days, they drank either nitrate-rich beetroot juice with grapefruit juice, beetroot juice with water, or nitrate-free beetroot juice with grapefruit juice. Both nitrate-rich beetroot drinks lowered systolic blood pressure, but the beetroot–grapefruit mix lowered systolic blood pressure a little more than the others.
If you’d like to add one of these juices to your diet, start small—maybe 4–8 ounces a day—and watch how you feel. You can sip them with breakfast, mix them into smoothies, or enjoy them as an afternoon drink.
Juices should support, not replace, your blood pressure medicines or healthcare provider’s advice. Consult with your healthcare provider before adding any of these juices to your diet.
