Beetroot has become one of the most talked-about functional foods in the wellness world, especially among people interested in energy, exercise performance and heart health. Once mainly associated with salads and juices, beetroot is now widely available in powders, capsules and concentrated shots designed to fit into modern health routines.
The reason for the growing interest is simple: beetroot is naturally rich in dietary nitrates, antioxidants and plant compounds that may support circulation, exercise performance and overall wellbeing. ¹
In this guide, we’ll look at what beetroot actually does, why it has become so popular, and whether beetroot supplements are worth considering.
What Makes Beetroot a “Superfood”?
Beetroot contains several naturally occurring compounds linked to health and performance support.
These include:
-
Dietary nitrates
-
Betalain antioxidants
-
Potassium
-
Folate
-
Fibre
The most researched compounds are dietary nitrates, which the body converts into nitric oxide. ² Nitric oxide helps relax and widen blood vessels, supporting healthy blood flow and oxygen delivery around the body.
This is one reason beetroot has become particularly popular among gym-goers, runners and endurance athletes.
Beetroot and Exercise Performance
One of the biggest reasons people search for beetroot supplements is their connection to exercise and stamina.
Research suggests dietary nitrates from beetroot may help improve exercise efficiency by supporting oxygen utilisation during physical activity. ³ In simple terms, this means the body may use oxygen more effectively during endurance exercise.
Because of this, beetroot products are commonly used before:
-
Running
-
Cycling
-
Gym training
-
High-intensity exercise
Some studies have also explored whether beetroot supplementation may help reduce perceived exertion during exercise, meaning workouts may feel slightly easier at the same intensity. ³
While effects vary between individuals, beetroot has become especially popular in sports nutrition because of these findings.
Beetroot and Circulation
Nitric oxide production is closely linked to healthy circulation.
By supporting blood vessel relaxation, beetroot may help maintain healthy blood flow and vascular function. ² This is why beetroot is often associated with cardiovascular wellness and active ageing support.
Some research has explored dietary nitrate intake in relation to healthy blood pressure levels, although beetroot supplements should not be viewed as treatments for cardiovascular conditions. ⁴
Instead, beetroot is best understood as part of a broader healthy lifestyle that includes balanced nutrition, movement and hydration.
Beetroot for Energy and Everyday Vitality
Unlike stimulants such as caffeine, beetroot does not provide a sudden “boost” of energy. Instead, its popularity comes from its potential role in supporting circulation and oxygen delivery during activity.
Many people report feeling:
-
More energised during workouts
-
Less fatigued during endurance exercise
-
Better exercise recovery support
Although responses vary, this “natural performance support” positioning has helped beetroot become one of the fastest-growing supplement categories in the UK wellness market.
Beetroot and Antioxidants
Beetroot’s deep red-purple colour comes from compounds called betalains.
Betalains are natural antioxidants that help protect cells from oxidative stress caused by free radicals. ⁵ Oxidative stress occurs naturally in the body and increases during exercise, pollution exposure and ageing.
This antioxidant content is another reason beetroot is commonly associated with overall wellness and recovery support.
Beetroot Powder vs Beetroot Juice: What’s the Difference?
Beetroot supplements are now available in several forms, including juices, powders and capsules.
Beetroot Juice
Often used by athletes because it naturally contains dietary nitrates in concentrated form.
Beetroot Powder
Convenient for smoothies or pre-workout drinks and usually made from dried beetroot concentrate.
Beetroot Capsules
A simple option for people who want the benefits of beetroot without the taste.
The best option often comes down to convenience and personal preference.
Is Beetroot Good for Heart Health?
Beetroot is often linked to heart health because nitric oxide helps support healthy circulation and vascular function. ²
Some studies have explored beetroot juice and nitrate intake in relation to maintaining healthy blood pressure levels already within the normal range. ⁴
However, it’s important to approach these findings carefully. Beetroot supplements are not intended to diagnose, treat or prevent cardiovascular disease.
Instead, they may complement a healthy lifestyle focused on exercise, balanced nutrition and heart-conscious habits.
Beetroot and Active Lifestyles
Beetroot’s popularity has grown significantly among active adults and sports enthusiasts.
Its appeal comes from being:
-
Plant-based
-
Naturally nitrate-rich
-
Easy to add into routines
-
Widely researched in sports nutrition
Many people now include beetroot alongside supplements such as magnesium, electrolytes and omega-3s as part of broader exercise support routines.
Are There Any Side Effects of Beetroot?
Beetroot is generally well tolerated for most healthy adults.
One harmless but sometimes surprising effect is beeturia, where urine or stools temporarily appear pink or red after consuming beetroot.
Some people may also experience mild digestive upset if taking highly concentrated beetroot products.
If you have medical conditions related to blood pressure, circulation or kidney health, it’s sensible to speak to a healthcare professional before using concentrated nitrate supplements regularly.
How to Choose a Quality Beetroot Supplement
Not all beetroot supplements are the same.
When choosing a product, look for:
-
Clearly labelled beetroot concentration
-
Transparent ingredient lists
-
Minimal unnecessary fillers
-
Reputable manufacturers and quality testing
Some beetroot products also combine ingredients such as vitamin C or electrolytes for additional exercise support.
Is Beetroot Worth the Hype?
Beetroot has earned its “superfood” reputation thanks to its naturally high nitrate and antioxidant content, along with growing research into circulation and exercise performance.
Whether consumed as food, juice or supplements, beetroot offers a convenient way to increase dietary nitrate intake as part of a healthy lifestyle. While it is not a miracle ingredient, it has become one of the most evidence-backed natural wellness trends in recent years.
For people interested in active ageing, exercise support or general wellbeing, beetroot is certainly more than just a passing trend.
