Beetroot: A Natural Way to Lower Blood Pressure and Boost Sports Performance
And what does it do for your blood pressure, stamina, and long-term health

Beets have long flown under the radar in both sports and clinical nutrition. But more people are now discovering that this humble root veggie might help boost endurance, sharpen blood flow, and even lower blood pressure—all with zero side effects and no prescription needed.
Let’s break down what beetroot actually does in the body, and whether beetroot powder or beet juice could have a place in your health and performance routine.
Beets are rich in dietary nitrates, a compound that turns into nitric oxide (NO) in your body. Nitric oxide helps relax and widen your blood vessels, which improves blood flow and reduces the amount of effort your heart needs to pump blood.
People use beet root powder, juice, and even raw or roasted beets as part of a diet for high blood pressure. Clinical trials have also shown that drinking beet juice or taking beet root powder helps lower your blood pressure, sometimes within hours of consumption.
How Beets Lower Blood Pressure
High blood pressure (aka hypertension) puts long-term stress on your heart and blood vessels. Over time, it increases your risk of heart attack, stroke, and cognitive decline.
But here’s where beetroot powder for high blood pressure gets interesting. A 2021 meta-analysis in the Journal of Nutrition found that beetroot juice significantly reduced both systolic and diastolic blood pressure, especially in people with high blood pressure.
How does it work? The nitrates in beets convert to nitric oxide, which relaxes blood vessels, increases circulation, and reduces the pressure your heart needs to exert. You might feel it as a warm flush or better muscle pumps during exercise. But more importantly, it helps take the load off your cardiovascular system.
Beets and Athletic Performance
Beyond heart health, beets also boost workouts. In fact, they improve oxygen delivery to working muscles, especially during endurance activities like running, cycling, or CrossFit.
One study in 2009 found that trained cyclists who drank beet juice could ride 16% longer before exhaustion. Another study showed beetroot helped runners improve their 5K times with no change in training.
This is why beetroot is often called a legal performance enhancer:
It doesn’t contain stimulants
It’s not banned in sports
It’s plant-based, natural, and safe for daily use
What’s Better: Beet Root Powder, Juice, or Whole Beets?
All three forms—beet powder, beet juice, and whole beets—contain natural nitrates. The key is getting enough of them consistently.
Beetroot powder is convenient and easy to add to smoothies or pre-workouts. A teaspoon, or about 3.5g, has around 300 to 500mg of nitrate.
Beet juice is fast-acting and often used before workouts. One cup (250ml) contains similar nitrate levels.
Whole beets are great as part of a long-term diet for high blood pressure, but you’d need to eat a large portion daily to match the nitrate dose of powder or juice.
Pro tip: Nitrate levels vary widely between beet products. Look for standardized nitrate content when choosing a beet supplement, especially if you’re using it for performance or to help lower your blood pressure.
Is Beetroot Right for You?
Beets are generally safe and well-tolerated, but there are a few things to know. Some people experience beeturia (pink urine) or pink stool, which are harmless, but surprising if you’re not expecting it.
If you’re prone to kidney stones, check with your doctor first. Beets lower blood pressure quickly, so if you're already on medication, monitoring your levels closely is a good idea.
How to Add Beets to Your Health Plan
Here’s how to start experimenting with beetroot for blood pressure and performance:
1. Start small: Try 1 to 2 teaspoons of beet powder or 1 cup of juice daily.
2. Time it right: Take it around 1 to 2 hours before training for workouts. For blood pressure support, consistency matters more than timing.
3. Track your response: At Mito Health, we offer comprehensive blood testing to monitor how your blood pressure, nitric oxide levels, and cardiovascular biomarkers are trending over time.
4. Stack smart: Beets pair well with other heart-healthy strategies like magnesium, potassium, omega-3s, and stress reduction.
