Salty tomato juice, licorice root tea, and caffeine-containing drinks are among the most commonly recommended options for raising low blood pressure. But the best juice for you depends on what’s causing your blood pressure to drop in the first place. Some juices work by increasing fluid volume, others by delivering sodium, and a few by directly affecting how your blood vessels behave.
Salted Tomato and Vegetable Juice
Sodium helps your body hold onto water, which increases blood volume and raises blood pressure. That makes salty juices one of the simplest tools for managing hypotension. Regular commercial tomato juice and vegetable juice blends like V8 are among the highest-sodium drinks you can buy at a grocery store, with some brands delivering 600 to 900 mg of sodium per cup.
Interestingly, unsalted tomato juice has the opposite effect. A study in Food Science & Nutrition found that unsalted tomato juice (containing only 16 mg of sodium per 200 ml serving) actually lowered blood pressure in people with prehypertension. So if you’re reaching for tomato juice specifically to raise your blood pressure, check the label and choose a version with added salt. The low-sodium versions marketed as heart-healthy will not help you here.
Licorice Root Drinks
Licorice root is one of the few natural substances that reliably raises blood pressure. The active compound, glycyrrhizin, blocks an enzyme in your kidneys that normally keeps cortisol in check. When that enzyme is suppressed, cortisol activates receptors that tell your kidneys to retain sodium and release potassium. The result is higher blood volume and increased blood pressure.
This effect is potent enough that it’s well documented in medical literature as a cause of dangerously high blood pressure in people who consume too much. Licorice root tea or juice (sometimes called “erk soos” in Middle Eastern cuisine) can be a useful short-term option for people with chronically low blood pressure, but it carries real risks. Excessive consumption drives potassium levels down, which can cause muscle weakness, heart rhythm disturbances, and in severe cases, cardiac arrest. Case reports describe serious complications in people drinking as little as one liter daily over a sustained period. If you try licorice root drinks, keep the amount small and occasional rather than making it a daily habit.
Orange Juice and Folate-Rich Juices
Low blood pressure sometimes stems from anemia, particularly the type caused by deficiencies in folate or vitamin B12. When you don’t have enough healthy red blood cells to carry oxygen efficiently, blood pressure can drop. Orange juice is one of the best juice sources of folate. Spinach-based green juices and fortified juices also deliver meaningful amounts. Johns Hopkins Medicine lists orange juice, oranges, spinach, and other leafy greens among the top dietary sources of folic acid.
B12 is harder to get from juice alone since it’s found primarily in animal products like meat, eggs, and dairy. But if your low blood pressure is linked to anemia, addressing the nutritional gap can gradually bring your numbers back up. A simple blood test from your doctor can tell you whether a deficiency is part of the picture.
Caffeinated Drinks
Caffeine constricts blood vessels and temporarily raises blood pressure, which is why coffee and tea are common go-to options for people who feel lightheaded from low blood pressure. Juice-based energy drinks and shots containing caffeine, guarana, or green tea extract produce a similar effect. One study found that a small 2-ounce caffeinated energy shot significantly raised diastolic blood pressure compared to a placebo, with the increase persisting for up to six hours.
The effect is short-lived and varies from person to person. Regular caffeine users develop tolerance, meaning the blood pressure bump gets smaller over time. For an occasional boost before standing up or heading out, a cup of green tea or a small caffeinated drink can help, but it’s not a long-term solution on its own.
Why Plain Water Also Matters
It’s worth noting that plain water, not technically a juice, has a surprisingly strong effect on low blood pressure. In a study of patients with severe orthostatic hypotension (the kind where blood pressure drops sharply upon standing), drinking about 16 ounces of water within five minutes raised standing systolic blood pressure from 83 to 114 mmHg within 35 minutes. Water also reduced the blood pressure drop that typically happens after eating by nearly half.
Dehydration is one of the most common and most fixable causes of low blood pressure. If you’re choosing juices to raise your blood pressure, drinking them alongside plenty of water amplifies the benefit. The fluid volume itself does part of the work.
Juices to Be Cautious With
Some popular “healthy” juices can make low blood pressure worse. Beetroot juice is rich in dietary nitrates, which your body converts into nitric oxide, a molecule that relaxes and widens blood vessels. This is great for people trying to lower high blood pressure, but counterproductive if yours is already low. Beetroot is one of the highest-nitrate vegetables available, alongside celery, spinach, and arugula. Green juices that feature these ingredients may nudge your blood pressure in the wrong direction.
Hibiscus tea, often sold as a juice or iced tea, also has well-established blood pressure-lowering properties. Pomegranate juice has shown similar effects in some research. If you’re prone to dizziness, fatigue, or fainting from low blood pressure, these are worth limiting or avoiding.
Timing and Practical Tips
When you drink matters almost as much as what you drink. Blood pressure tends to be lowest in the morning and after meals. Having a salty juice or caffeinated drink about 15 to 30 minutes before you need to stand or be active gives your body time to absorb the fluid and respond. The water-drinking study showed peak blood pressure improvement at around 35 minutes after consumption.
Postprandial hypotension, the blood pressure drop after eating, is particularly common in older adults. Drinking 16 ounces of fluid with or just before a meal cut the post-meal blood pressure drop roughly in half in clinical testing. Sipping a glass of salted tomato juice or vegetable juice alongside breakfast is a practical way to combine sodium, fluid, and nutrients in one step.
Small, frequent servings tend to work better than one large drink. Your kidneys will simply excrete excess fluid if you overwhelm them all at once. Spreading your intake across the day keeps blood volume steadier and reduces the chance of those lightheaded moments when you shift positions.
