The Best Time to Drink Beetroot Juice to Lower Your Blood Pressure

If you’re considering trying beet juice to treat high blood pressure, timing can be important. Beet juice can lower blood pressure throughout the day, so drinking it earlier may be more beneficial. However, there are cases where you might benefit from drinking at other times of the day.

The blood pressure lowering effects of beet juice can last most of the day. For this reason, having a drink in the morning or early afternoon can be very helpful in supporting blood pressure during daily activities.

Research has shown that the hypotensive effect can last up to about 10 hours, and in some cases up to 24 hours. For this reason, some researchers believe that daily administration may be necessary to achieve more consistent blood pressure support.

It is important to note that not all studies show a benefit and changes may be less in women or people with lower baseline blood pressure.

A 2024 study looked at physically inactive postmenopausal women with high blood pressure who drank beet juice before doing a moderate treadmill workout. After drinking beet juice, their systolic blood pressure (top blood pressure number) dropped about nine points during recovery.

The study also found better blood vessel function after exercise, which can promote blood flow and lower blood pressure. Although the study is limited, it suggests that beet juice could give some women an extra boost during their workouts.

Drinking beet juice regularly may lower blood pressure, which may worsen the effects of prescription blood pressure medications. For some people, this combination could cause blood pressure to drop too far. This may be especially important for people taking multiple blood pressure medications.

If you’re taking blood pressure medication, ask your doctor if beetroot juice could help you manage your blood pressure, and if so, when would be the best time to drink it.

Beetroot juice can start lowering blood pressure fairly quickly, but the timing varies between people. In several research studies, the greatest drop in blood pressure occurred about two to three hours after drinking beet juice. Some research found a smaller early decline within 30 to 60 minutes, but this effect often faded later in the day.

Beet juice is high in nitrate, which your body converts into nitric oxide. It is a gas that helps relax and widen blood vessels. The blood vessel widening effect can lower blood pressure by improving blood circulation. Nitrate from beet juice has been shown to cause slight decreases in blood pressure, which may help support heart health over time.

If you want to drink beet juice to lower blood pressure, consider these next steps:

• Talk to your healthcare professional: Before consuming beet juice, especially if you are taking blood pressure medication, ask if beet juice is safe for you and how often you can use it.
• Start small and be consistent: If your doctor approves, start with a modest serving and drink it at the same time each day. Morning or early afternoon may be more effective due to their hypotensive effects.
• Track your blood pressure at home: Check your readings regularly. Watch for symptoms such as dizziness or confusion, which may indicate that your blood pressure is dropping too low.
• Update your provider: Share your blood pressure results and symptoms with your doctor so he or she can help you decide whether to continue, adjust, or stop taking beetroot juice.
