Betabel (beetroot) is packed with nutrients that support heart health, exercise performance, brain function, digestion, and liver protection. A 100-gram serving delivers over 300 mg of potassium, 83 micrograms of folate (covering about 28% of your daily needs), 10 mg of vitamin C, and 2.5 to 3 grams of fiber. But the real star of the show is a compound called dietary nitrate, which your body converts into nitric oxide, a molecule that relaxes blood vessels and improves blood flow throughout your body.
Heart Health and Blood Pressure
The nitrates in betabel follow a specific path once you eat them. Bacteria on your tongue first convert nitrate into nitrite, and then your body reduces that nitrite into nitric oxide. This nitric oxide signals your blood vessels to widen, which lowers the pressure your heart has to pump against. The effect is well documented in healthy adults, though results in people with existing conditions like type 2 diabetes have been less consistent.
Beyond the nitrate pathway, betabel’s high potassium content helps your kidneys flush out excess sodium, another factor in maintaining healthy blood pressure. The folate in beets also plays a role in cardiovascular health by helping regulate homocysteine, an amino acid that can damage blood vessel walls when levels run too high.
Exercise Performance and Stamina
Betabel juice has become one of the most popular natural supplements among endurance athletes, and for good reason. In a controlled study of female athletes, those who drank beetroot juice saw their maximal oxygen consumption (a key measure of aerobic fitness) increase by nearly 5%, while a placebo group showed no improvement. The mechanism is straightforward: nitric oxide widens blood vessels, delivering more oxygen to working muscles and helping them use that oxygen more efficiently. This translates to less fatigue during prolonged exercise.
If you want to use betabel as a pre-workout boost, timing matters. Blood levels of nitrite peak about 2 to 3 hours after you consume the nitrates, so drinking beetroot juice roughly 90 minutes before exercise puts you in the right window. Most studies showing performance benefits used doses containing 6 to 8 millimoles of nitrate, which works out to roughly 140 to 500 ml of juice depending on concentration. Concentrated beetroot “shots” of about 70 ml are widely available and deliver an effective dose in a small volume. One important detail: avoid using antiseptic mouthwash before exercise, since the bacteria on your tongue are essential for converting nitrate into nitrite.
Brain Function and Blood Flow
Your brain consumes a disproportionate share of your body’s blood supply, and reduced blood flow to the brain is one of the earliest changes associated with cognitive decline. Betabel’s nitrates can help here too. Research has shown that drinking about 16 ounces of beetroot juice acutely increased blood flow to white matter in the frontal lobe, specifically along the pathways that connect areas responsible for executive control, like decision-making, attention, and working memory.
These frontal brain regions are among the first to suffer from age-related vascular decline, which makes the finding particularly relevant for older adults. A long-term study from the Australian Imaging, Biomarkers and Lifestyle Study of Ageing found that among people at elevated genetic risk for Alzheimer’s disease, each additional 60 mg per day of plant-based nitrate at the start of the study was linked to better memory scores over a 10.5-year follow-up period, including improved recall and recognition. While no trials have yet tested betabel directly in people with Alzheimer’s, the vascular mechanism is promising.
Digestive Health
With 2.5 to 3 grams of fiber per 100-gram serving, betabel contributes meaningfully to your daily fiber intake. That fiber does double duty in your gut: it adds bulk to stool and helps keep things moving, reducing the risk of constipation, and it feeds beneficial bacteria in your large intestine. A diverse, well-fed gut microbiome strengthens your immune system and helps protect against digestive diseases. Eating betabel regularly, whether roasted, juiced, or raw in salads, is a simple way to support gut health alongside other high-fiber foods.
Liver Protection
Betabel contains a compound called betaine, which acts as a methyl group donor in your liver’s chemical processes. In practical terms, betaine helps your liver process fats rather than letting them accumulate. A clinical trial comparing beetroot juice to a Mediterranean diet in patients with non-alcoholic fatty liver disease found that beetroot juice had a protective effect on the liver, likely because betaine supports the biochemical pathways that keep fat from building up in liver cells. For people concerned about liver health, adding betabel to your diet is a reasonable, low-risk strategy.
Side Effects Worth Knowing About
The most noticeable side effect of eating betabel is completely harmless: beeturia, a reddish or pinkish color in your urine or stools caused by pigments called betacyanins. This happens in roughly 10% to 14% of the general population, and the rate jumps to about 45% in people with certain types of anemia or iron deficiency. The discoloration can be startling if you’re not expecting it, but it resolves on its own and doesn’t indicate any health problem.
The more serious consideration involves oxalates. Beetroot juice contains 60 to 70 mg of oxalate per 100 ml, making it one of the highest-oxalate beverages you can drink (second only to rhubarb nectar). For most people this is fine, but if you’ve had calcium oxalate kidney stones, you should be mindful of how much betabel juice you consume. Eating whole beets in normal food portions is less of a concern than drinking large quantities of concentrated juice, since the volume adds up quickly.
