Raw Beetroot delivers a concentrated dose of dietary nitrate, betalain pigments, folate, and fiber that cooking partially breaks down or reduces. Much of the interest in beetroot comes from two key compounds: nitrates that can be converted into nitric oxide and betalains that provide antioxidant effects..
Once eaten, nitrate from beetroot is converted step by step into nitric oxide, a molecule that relaxes and widens blood vessels.
Wider blood vessels mean easier blood flow, which is the mechanism behind most of beetroot’s studied benefits, from blood pressure to endurance.
Raw beetroot preserves more of its natural nitrate and vitamin C because it hasn’t been exposed to heat. However, boiling can lower its oxalate content, which may be important when considering potential side effects.
Key Takeaways

Blood Pressure: The Best Supported Benefit
Beetroot’s nitrate content is the reason it shows up so often in blood pressure research. A 2025 systematic review and dose response meta analysis covering 75 randomized controlled trials found that nitrate supplementation lowered both systolic and diastolic blood pressure, with the effect scaling with dose.
A separate meta analysis published in Frontiers in Nutrition found that beetroot juice supplementation reduced systolic blood pressure by an average of 4.4 mmHg. Other estimates put the typical reduction from regular beet nitrate intake at 4 to 8 mmHg.
This matters most for people managing borderline or high blood pressure, but it also means beetroot can compound the effect of blood pressure medication.
Anyone on antihypertensive drugs should treat regular raw beetroot intake as something to mention at their next checkup, not a silent addition to the diet.

Exercise Performance and Recovery
Athletes and recreational exercisers are one of the most studied groups for beetroot intake, and the results are fairly consistent. A 2025 umbrella review of 15 meta analyses found that beetroot juice supplementation can improve muscle strength in athletes and increase VO2max in healthy non athletes.
A 2022 systematic review found that beetroot supplementation led to faster recovery of speed, strength, and endurance test performance after exercise, along with less post exercise muscle soreness.
Systematic reviews in Sports Medicine covering 20 studies also confirmed that dietary nitrate from beets improves endurance performance in trained athletes and recreational exercisers.
The mechanism is the same nitric oxide pathway described above. More nitric oxide means wider blood vessels, which lowers the oxygen cost of submaximal exercise and can translate into better endurance and reduced perceived effort during a workout.
Cardiovascular and Metabolic Effects Beyond Blood Pressure
A decade long review of beetroot research from 2015 to 2025 found that clinical trials supported improvements in blood pressure, glycemic control, and exercise performance across healthy individuals, people with hypertension, people with diabetes, and even COVID 19 patients.
In vitro studies have also shown antiproliferative and pro apoptotic effects of beetroot’s betalain compounds on cancer cells, and animal studies confirmed metabolic, cardiovascular, and liver protective benefits, though this evidence is still preclinical and has not been confirmed in large human trials.
Emerging research on specific populations is expanding too. In one study on patients with obstructive sleep apnea, a single dose of beetroot juice blunted the usual morning rise in systolic blood pressure and improved breathing responses under low oxygen conditions.
Nutrient Profile of Raw Beetroot
Raw beetroot delivers more than nitrate alone. A 100 gram serving of cooked beets provides about 20 percent of the daily folate requirement, a nutrient essential for DNA synthesis and red blood cell formation, and raw beetroot generally retains at least as much.
Beyond folate, beetroot is also a source of potassium and fiber, and it delivers naturally occurring nitrates that support healthy blood flow.
This combination of fiber plus nitrate is one reason whole raw beetroot tends to have a milder effect on oxalate related risk than concentrated beetroot juice, since fiber slows absorption.
Side Effect 1: Beeturia, the Pink Urine Effect
Beeturia is pink or red discoloration of urine after eating beetroot, and it is the most commonly reported reaction to the vegetable.
It affects roughly 10 to 14 percent of people and results from unmetabolized betacyanin pigments passing through the digestive system and into urine.
Whether someone experiences beeturia depends on stomach acid levels, gut transit speed, and individual variation in how the intestines absorb pigment, not on how much beetroot they ate in a single sitting. For the majority of people, it is not a medical condition. It resolves on its own once beetroot intake drops.
The only case worth flagging to a doctor is persistent pink or red urine when someone has not eaten beets or other red foods recently, since that pattern is not explained by beeturia and deserves a checkup.
Side Effect 2: Oxalates and Kidney Stone Risk
Raw beetroot contains oxalates, and beetroot juice in particular tends to have higher levels of soluble oxalates than the whole cooked vegetable, which raises kidney stone risk when consumed in excess.
A 2019 dietary oxalate review confirmed that high oxalate foods consistently raise urinary oxalate in people who already form stones, and beetroot falls into that category.
Cooking changes this picture somewhat. Boiling whole beets reduces the bioavailability of their oxalates, so people managing stone risk who still want the benefits of beetroot may do better with cooked beets over raw or juiced versions.
Oxalic acid in beets can also raise uric acid levels in some people, which can trigger gout, a painful joint condition, in those who are already prone to it.
Pairing beetroot with a calcium source, such as cottage cheese or feta, at the same meal helps because calcium binds with oxalate in the intestines before it reaches the kidneys.
People with no personal or family history of kidney stones do not need to avoid raw beetroot. The oxalate concern is specific to those already predisposed to calcium oxalate stone formation, and even then, kidney stones usually develop from a combination of factors rather than a single food.
Side Effect 3: Digestive Upset and Blood Pressure Interactions
Occasional bloating, loose stools, or cramping have been reported with concentrated beetroot juice at higher doses, though this is less common with whole raw beetroot eaten as food.
Because beetroot nitrate lowers blood pressure by roughly 4 to 8 mmHg, it can interact with blood pressure medication and other drug classes, so people already on antihypertensive treatment should moderate intake and monitor for symptoms of low blood pressure such as dizziness or lightheadedness.
People who already run low blood pressure should also watch their levels carefully, since beetroot’s nitric oxide effect can push it lower still.
