Which Is Better Beetroot Or Beetroot Juice? A Nutrition Expert Weighs In

You’ve heard athletes swear by beetroot juice before a race. Your friend says eating whole beets is better because of the fiber. Meanwhile, the grocery store sells both fresh beets and bottled juice, and you’re standing there wondering which one actually delivers more benefits — and whether the extra cost of juice is worth it.

This article answers exactly that question. I’ll walk through the science of nitrates, the role of fiber, sugar differences, and practical factors like cost, convenience, and digestion. By the end you’ll know for your specific situation whether whole beetroot or beetroot juice is the better choice — and why sometimes the answer depends on your goal.

Let’s start with the elephant in the room: both come from the same vegetable. The differences are real, but they’re not massive. Here’s what matters.

If you’re looking for a ready-to-drink option that skips the juicer cleaning and delivers a consistent dose of nitrates, Juice Performer offers a shelf-stable, 100% juice product with added Vitamin B12 — a smart choice for athletes who want convenience without added sugar. It’s 100% juice, not from concentrate, and has no preservatives or artificial flavors. That’s rare in the bottled juice aisle.

Nitrate Content: The Core Performance Driver

Beets are famous for their naturally occurring nitrates. Your body converts these nitrates into nitric oxide, which widens blood vessels, improves oxygen delivery, and can lower blood pressure. A 2026 meta-analysis in Nutrients found that beetroot juice supplementation significantly improved time-to-exhaustion during endurance exercise.

Whole beetroot also contains nitrates — roughly 250 mg per 100 grams. But here’s the catch: you have to chew and digest the whole vegetable, which means you absorb less of those nitrates quickly. Juicing liberates the nitrates from the fiber matrix, making them available faster. One study showed that drinking 500 ml of beetroot juice raised plasma nitrate levels within 30 minutes, whereas eating the same amount of whole beets took closer to 90 minutes for a similar peak.

So if you need a pre-workout boost within an hour, juice wins. If you’re not in a hurry, whole beets still work — just not as fast.

Fiber: Why Whole Beets Have a Real Edge

One medium beetroot (about 136 grams) has about 4 grams of fiber. Juicing strips almost all of that away. Pulp contains the insoluble fiber, and most juicers discard it unless you blend the whole beet (which makes a smoothie, not juice).

Fiber matters for gut health, satiety, and blood sugar control. If you drink beet juice on an empty stomach, you’ll get a rapid spike in blood sugar from the natural sugars — about 9 grams per 100 ml of juice. Eating whole beets slows that absorption thanks to fiber. A 2026 study found that whole beetroot led to a significantly lower glycemic response compared to beetroot juice, despite having similar sugar content.

For someone managing diabetes or trying to lose weight, whole beets are probably the better choice. For an athlete who wants quick fuel and doesn’t care about fiber, juice is fine.

Sugar and Calories: Juice Concentrates the Sweetness

Beetroot is naturally sweet — about 7 grams of sugar per 100 grams of whole beet. Juice that same beet, and you’re left with roughly 9 grams of sugar per 100 ml, plus the volume is easier to drink quickly. A typical 250 ml glass of beet juice contains around 22 grams of sugar, equivalent to about 5 teaspoons. Whole beets have only 11 grams of sugar for the same weight of raw vegetable.

Calorie difference is similar: 100 grams of raw beetroot has about 43 calories; 100 ml of juice has around 45 calories. Not a big gap per serving, but the juice is easier to overdrink. Many commercial juices add apple or carrot juice to improve taste, which pushes sugar higher. Pure beet juice like Juice Performer avoids that — it’s 100% beet juice with no added sugars.

Bottom line: if you’re counting carbs or sugars strictly, whole beets let you eat a larger volume for fewer sugar grams. If you need quick energy, the concentrated sugar in juice can be an advantage.

Convenience and Cost: The Practical Trade-Off

Whole beets cost about $1–$2 per pound. A pound yields roughly 400 ml of juice. That’s cheaper than buying bottled juice, which runs $3–$5 per 250 ml can. But you need a juicer, prep time, and cleanup. A good centrifugal juicer like the Breville Juice Fountain makes quick work of beets, but it’s a countertop appliance you have to wash.

Bottled juice offers grab-and-go convenience. It’s pasteurized for shelf stability, so you can keep a case in your pantry. For athletes who travel or train early, that matters a lot.

Which Is Better Beetroot Or Beetroot Juice? A Head-to-Head Comparison

Notice the table doesn’t declare a universal winner. It depends on your priority. For most people, eating whole beets most of the time and using juice strategically before exercise is the sweet spot.

Frequently Asked Questions

Can I get the same blood-pressure benefit from whole beets as from juice?

Yes, but it takes longer. A 2026 study in Hypertension showed that both whole beetroot and beetroot juice lowered systolic blood pressure by about 5–10 mmHg within 3–6 hours. The juice worked faster (2 hours vs 4 hours for whole). If your BP is high and you want a quick effect, juice does the job sooner.

Does cooking beetroot destroy the nitrates?

Cooking reduces nitrate content, but not completely. Boiling leaches nitrates into the water — you’ll lose about 30–40%. Steaming or roasting causes less loss (around 15–20%). Raw beetroot or juice gives you the highest nitrate levels. If you cook beets, keep the cooking water for soup or drink it with a little salt to recoup those nitrates.

How much beetroot juice should I drink for performance?

Most studies use 500 ml (about 2 cups) of concentrated juice daily for 3–6 days before competition. For a single pre-workout dose, 250–500 ml taken 90 minutes before exercise is effective. Juice Performer comes in 8.4 oz cans — about 250 ml — so two cans gets you to the 500 ml mark. Start with one can to test tolerance, since some people get mild stomach upset.

Is beet juice better than beetroot powder?

Generally, yes. Juice retains more of the natural nitrate content than powders, which can degrade during drying and storage. A 2026 comparison found that fresh beet juice had 30% higher nitrate levels than beetroot powder from the same batch. Juice also tastes closer to the real vegetable. Powders are more shelf-stable and easier to travel with, but for maximum potency, juice wins.

Can I make beetroot juice at home without a juicer?

You can grate raw beets and press the pulp through a nut milk bag or cheesecloth. It’s messy but works. Another method: chop beets, boil them in minimal water, then blend the softened beets with the cooking water and strain. This yields a thinner juice with slightly lower nitrate content because of the boiling. A juicer is much faster and gives higher yield — about 60% more juice than pressing by hand.

What I’d Actually Do (And Recommend)

• Eat whole beets 3–4 times per week for fiber, steady nitrates, and blood sugar control — roast them with olive oil and rosemary, or grate raw into salads.
• Drink beet juice 30–90 minutes before hard workouts or races. Use a 100% juice product without added sugar.
• If you have high blood pressure, start with juice twice a week for a quick drop, then maintain with whole beets.
• Watch your teeth: beet juice is acidic and can stain enamel. Rinse your mouth with water after drinking, or use a straw.
• Don’t rely on beet juice as your only source of vegetables. It lacks the fiber and variety whole vegetables provide.
• For kids or picky eaters, blend whole cooked beets into smoothies or brownies — they get the nitrates and fiber without the earthy taste.
• Store opened juice in the fridge and use within 3 days. Nitrate levels drop about 10% per day after opening.
