It doesn’t get the same attention as kale or blueberries. But researchers say beets may be one of the most powerful foods you can put on your plate — and the science behind why is more compelling than most people realize.
Beets are having a serious scientific moment. Over the past few years, a growing body of peer-reviewed research has pointed to the same conclusion: this humble root vegetable packs measurable, clinically studied benefits that most Americans aren’t getting — because most Americans aren’t eating them.
What Happens Inside You When You Eat a Beet
The most studied benefit starts with a single compound: dietary nitrate. When you eat beets, your body converts those natural nitrates into nitric oxide — a molecule that signals your blood vessels to relax and widen. The result is improved circulation, reduced arterial stiffness, and lower blood pressure.
This isn’t wellness blog theory. It’s backed by randomized clinical trials. According to a review published in Life Extension and assessed by a doctor of chiropractic in December 2024, a systematic review of clinical trials concluded that beetroot juice supplementation should be promoted as a key component of a healthy lifestyle to control blood pressure in both healthy and hypertensive individuals. A randomized crossover trial with 15 healthy young adults found that both whole beets and beet juice produced significant reductions in systolic and diastolic blood pressure.
Raw beets, the research notes, provide roughly 200 milligrams of nitrate per 100 grams — among the highest concentrations of any commonly eaten vegetable.
The Heart Isn’t the Only Organ That Benefits
A 2024 clinical study found that seven days of dietary nitrate supplementation significantly improved vascular function in postmenopausal women, according to researchers cited by Beet-It US. This matters because heart disease risk rises sharply after menopause — and effective, accessible nutritional strategies are increasingly in demand.
Meanwhile, researchers at the University of Exeter conducted what they described as the largest study of its kind, published in Free Radical Biology and Medicine. Their finding was striking: beet juice doesn’t just deliver nitrates passively. It actively reshapes the oral microbiome, increasing beneficial bacteria and improving the body’s own ability to convert dietary nitrates into nitric oxide. In older adults, this process had a direct, measurable effect on blood pressure and vascular health.
Sharper Thinking, Stronger Workouts
The benefits extend well beyond the cardiovascular system. A December 2025 systematic review published in Nutrients by researchers from the Medical University of Lodz found that beetroot-derived nitrates improve endurance, oxygen efficiency, muscular power, and recovery — particularly in recreational athletes and moderately active individuals.
The cognitive findings were equally notable. According to the same review, a 2024 study by Heiland and colleagues found that participants who supplemented with beet juice performed significantly better on a serial subtraction task compared to those who received a placebo. A separate study found that two weeks of beet juice supplementation improved simple reaction time in people with Type 2 diabetes.
Betalains — the pigments that give beets their deep red color — also contribute. According to peer-reviewed research published in the National Institutes of Health database, these compounds act as potent antioxidants, helping to reduce oxidative stress, protect against DNA damage, and support liver function.
What We Know

Beets are among the highest natural sources of dietary nitrates available in the average grocery store
Nitrates from beets convert to nitric oxide, relaxing blood vessels and lowering blood pressure — confirmed by multiple clinical trials
A University of Exeter study found beet juice reshapes oral bacteria in older adults, improving their natural nitrate conversion
A 2025 systematic review confirmed benefits for endurance, recovery, and cognitive reaction time
Betalains provide antioxidant protection and may inhibit tumor cell growth, according to NIH-published research
Beets also supply folate, potassium, manganese, and iron — nutrients tied to brain, muscle, and metabolic function
Dietary fiber in beets slows glucose absorption and supports gut bacteria
Beeturia (pink-tinted urine) is harmless and affects some people
Those prone to kidney stones or managing blood sugar should moderate intake and consult a doctor

Why This Matters Right Now
Nearly half of American adults have high blood pressure, according to the CDC — and the majority don’t have it under control. Prescription rates are climbing. Healthcare costs are rising. And many people are actively looking for nutritional strategies that actually hold up under scrutiny.
Beets aren’t a cure. But the evidence that a single, affordable, widely available vegetable can meaningfully support heart health, cognitive function, and physical performance — without a prescription — is exactly the kind of finding Americans need to hear more of.
One medium beet costs less than a dollar. The research says it may be doing more than most people’s supplements.
