Beetroot is a nutrient-rich root vegetable known for natural nitrates that support nitric-oxide production and blood flow. Evidence suggests modest blood-pressure benefits and potential performance support. Learn best ways to eat it, and who should be cautious.

Beetroot (also called beet) is a deep red root vegetable that’s famous for one thing: dietary nitrates. Your body can convert nitrates into nitric oxide, a molecule that helps blood vessels relax and widen. That’s why beetroot shows up in research on blood pressure and exercise performance — and why it’s popular in “beet juice” shots.
But beetroot isn’t just a nitrate delivery system. It also brings fiber, folate, potassium, and colorful plant pigments called betalains. Here’s what beetroot can (and can’t) do — in an evidence‑aligned, practical way.
Beetroot is mostly water and carbs, with a bit of fiber. The standout nutrients are folate (B9) and potassium, plus manganese (important for normal energy metabolism and antioxidant enzymes). You’ll also get a mix of polyphenols and betalains, the pigments responsible for the red/purple color.
Pro tip: cooked beets are often easier on digestion than large raw portions. If raw beets don’t love you back, start with roasted or steamed.
Dietary nitrates from beetroot can be converted into nitric oxide via a pathway that involves oral bacteria. Nitric oxide helps blood vessels relax, which supports circulation. This is the core mechanism behind most beetroot research.
Practical note: antibacterial mouthwash right before beetroot can reduce nitrate conversion for some people. If you’re specifically using beetroot for performance or blood‑flow support, consider avoiding strong antiseptic mouthwash around that time.
Multiple studies suggest nitrate‑rich beetroot juice can reduce blood pressure by a small to moderate amount in some populations. It’s not a substitute for prescribed treatment, but it can be a helpful supportive habit alongside a heart‑healthy diet.
Best use: consistency tends to work better than random “beet sprints.” If you want to try it, start with food first (roasted beets, salads, soups), then consider juice if you tolerate it.
Beetroot is popular in sports nutrition because nitric oxide can improve blood‑flow delivery and muscle efficiency. Some research finds improved endurance performance or reduced oxygen cost during steady efforts, especially in recreational athletes.
Why results vary: baseline diet (already high nitrate intake), training status, dose, timing, and the nitrate content of the product all influence outcomes. Translation: beetroot can help — but not everyone feels it.
Beetroot contains betalains (like betanin), which have antioxidant and anti‑inflammatory activity in laboratory and early research. This is promising, but the “real‑life” effect depends on the whole diet pattern.
Keep it grounded: think of beetroot as one helpful color in a wider “eat the rainbow” strategy, not a single superfood fix.
Whole beets contribute dietary fiber, which supports bowel regularity and helps meals feel more satisfying. Fiber also supports a healthier gut environment over time.
Simple move: add roasted beet wedges to a bowl with greens, beans/lentils, olive oil, and lemon — fiber + flavor + meal prep friendly.
Folate supports normal cell division and red blood cell formation, while potassium supports normal nerve and muscle function and helps balance sodium in the diet. Beetroot isn’t the only source — but it’s a solid contributor, especially in a varied plant‑forward diet.
If you’re trying beetroot specifically for training, the key variables are timing, dose, and consistency.
Simple approach: start with whole beets a few times per week. If you’re experimenting with beet juice, keep the dose modest and track how you feel (energy, stomach comfort, perceived effort). If you’re on blood‑pressure medication, talk with your clinician before using large “shot” style doses.
Beetroot is the root. Beet greens (the leafy tops) are a different nutritional story: they’re more like other leafy greens and can be higher in certain vitamins and minerals. If you buy beets with greens attached, don’t toss them — sauté them like spinach.
Juice can deliver nitrates more conveniently, but whole beets provide fiber and tend to be easier to fit into normal meals without huge swings in intake. For everyday health, whole beets are a great default.
That’s usually beeturia — pigments (betalains) passing through. It’s typically harmless. If you see red urine without eating beets, treat it as a medical check‑in.
Yes — but check the label. Some pickled beets come with lots of added sugar and sodium. They can still be a useful “add‑on” food; just balance them with less salty parts of the meal.
Your liver and kidneys handle detoxification. Beetroot is a nutritious food that supports overall diet quality, but it doesn’t “detox” you in a special way.
Roast a batch, store it in the fridge, and add a handful to lunches. Pair with protein (beans, lentils, fish, eggs, yogurt) and a healthy fat (olive oil, nuts) to make it a real meal.
Beetroot is a practical “upgrade” food: it’s nutrient‑dense, adds fiber and folate, and its natural nitrates can support blood flow — with evidence for modest blood‑pressure benefits and potential performance support. Use it as part of a balanced diet, keep expectations realistic, and be cautious if you have low blood pressure or a history of kidney stones.
