Several everyday beverages can meaningfully lower blood pressure when consumed regularly, with some dropping systolic pressure by 5 to 13 points over a few weeks. These aren’t replacements for medication if you need it, but they’re effective enough that researchers have measured their effects in clinical trials. Here’s what works, how much to drink, and how quickly you can expect results.
Hibiscus Tea
Hibiscus tea is one of the most studied natural drinks for blood pressure. In a USDA-funded trial, participants who drank three cups daily for six weeks saw their systolic blood pressure drop by 7.2 points on average. Those who started with the highest readings got even better results: a 13.2-point drop in systolic pressure and a 6.4-point drop in diastolic pressure.
You can brew it from dried hibiscus flowers (sometimes sold as “flor de Jamaica”) or buy it in tea bags. Drink it hot or iced, but skip the added sugar. Three cups a day is the dose that produced results in trials. One important caution: if you take a thiazide diuretic (a common blood pressure medication), hibiscus can increase the drug’s concentration in your body and amplify both its effects and side effects. Talk with your pharmacist before combining the two.
Beetroot Juice
Beetroot juice works through a different mechanism than most other options on this list. It’s rich in naturally occurring nitrates, which your body converts into a compound that relaxes and widens blood vessels. A meta-analysis of trials in people with high blood pressure found that daily beetroot juice, in amounts ranging from about 70 to 250 mL (roughly a quarter cup to one cup), lowered blood pressure over periods as short as three days and as long as two months.
The taste is earthy and strong. Many people find it more palatable mixed with a splash of apple or lemon juice. Look for varieties without added sodium or sugar. Store-bought “shots” of concentrated beetroot juice (typically 70 mL) are a convenient option if you don’t want to juice raw beets yourself.
Pomegranate Juice
A systematic review of 14 clinical trials involving 573 people found that pomegranate juice reduced systolic blood pressure by about 5 points on average. Drinking 300 mL or less per day (roughly 10 ounces, a bit more than a cup) produced a slightly larger drop of around 6 points. Effects showed up within two months of daily consumption.
Pomegranate juice is naturally high in sugar and calories, so portion size matters. Stick to 100% juice with no added sweeteners, and keep it to one glass a day. The blood pressure benefit comes from the antioxidant compounds concentrated in the fruit, so diluting it with water is fine and can help manage the sugar load.
Unsalted Tomato Juice
Tomato juice is a good source of potassium, a mineral that counterbalances sodium’s effect on blood pressure. In a study of 94 people with untreated prehypertension or hypertension, regular intake of unsalted tomato juice lowered systolic pressure from about 141 to 137 and diastolic pressure from about 83 to 81. Those are modest numbers, but they came without medication.
The key word here is “unsalted.” Many commercial tomato juices are loaded with sodium, which would cancel out any benefit. Check the label and choose a low-sodium or no-salt-added version. One cup daily is a reasonable amount.
Low-Fat Milk
Dairy, particularly low-fat varieties, is a cornerstone of the DASH diet, which is specifically designed to lower blood pressure. Low-fat milk delivers a combination of potassium, magnesium, and calcium, plus naturally occurring proteins that help relax blood vessels. Research following over 2,000 older adults at high cardiovascular risk confirmed the protective association between low-fat dairy intake and blood pressure.
Full-fat dairy doesn’t show the same consistent benefits in studies. If you’re choosing between whole milk and skim or 1%, the lower-fat option is better for blood pressure purposes. Two to three servings of low-fat dairy per day aligns with DASH diet recommendations.
Plain Water
This one is easy to overlook, but staying well-hydrated plays a real role in blood pressure regulation. When you’re dehydrated, sodium levels in your blood rise, which triggers your body to release a hormone called vasopressin. Vasopressin causes blood vessels to constrict, pushing pressure up. Chronic mild dehydration, the kind many people live with without realizing it, can keep this cycle running in the background.
There’s no magic amount, but if your urine is consistently dark yellow, you’re likely not drinking enough. Increasing your water intake won’t produce the dramatic drops you’d see from hibiscus tea or beetroot juice, but it removes a common contributor to elevated readings.
What to Cut Back On
What you stop drinking matters as much as what you start. Sugary beverages, including regular soda and sweetened energy drinks, are linked to higher blood pressure. Data from the Framingham Heart Study found that people consuming one or more servings of soft drinks per day had roughly 18% higher odds of developing elevated blood pressure, and that estimate may understate the risk because it grouped regular and diet soda together.
Alcohol is another major factor. More than moderate amounts (one drink a day for women, two for men) reliably raises blood pressure, and the effect is dose-dependent: the more you drink, the higher it goes. Cutting back on alcohol is one of the fastest ways to see a measurable improvement in your readings. Excessive caffeine can also cause short-term spikes, though moderate coffee or tea intake (two to three cups a day) doesn’t appear to be a significant long-term risk for most people.
How Quickly These Changes Work
You won’t need to wait months to see movement. Research from the American Heart Association found that the DASH diet pattern, which includes many of these beverages, lowers blood pressure within one week and sustains that effect over time. Reducing sodium intake produces gradual improvement that continues for at least four weeks and possibly longer. Individual drinks like hibiscus tea showed significant results within six weeks in clinical trials, while beetroot juice has shown effects in as little as a few days.
For context on what your numbers mean: normal blood pressure is below 120/80, elevated is 120 to 129 systolic with diastolic still under 80, stage 1 hypertension is 130 to 139 systolic or 80 to 89 diastolic, and stage 2 hypertension is 140/90 or higher. A 5 to 13 point drop, which is the range these beverages can deliver, is enough to move someone from one category to a lower one. That’s a meaningful shift from drinks alone, and combining several of these strategies can add up to even larger improvements.
