Dietary Nitrates in Beetroot & Heart Health Science
Dietary Nitrates in Beetroot & Cardiovascular Health: What Does Science Say?
Beetroot contains a significant amount of dietary nitrate (NO3−). Nitrate can be metabolised to nitrite and subsequently nitric oxide, a signalling molecule that has been suggested to be involved in peripheral blood-vessel relaxation and/or other aspects of vascular function.
The potent vasodilatory properties of nitric oxide have generated interest in the recent clinical literature in investigating the effects of beetroot juice and nitrate supplementation on blood pressure and endothelial function but results have not been entirely consistent.
Importantly, almost all of the studies published to date have utilised beetroot juice or nitrate doses measured in beetroot juice, rather than packaged beetroot chips.
What Is a Dietary Nitrate?
Dietary nitrates are naturally occurring compounds that can be found in several vegetables, with beetroot being one of the more widely studied nitrate-rich foods, alongside some types of leafy greens. The body also uses dietary nitrate via a pathway that is often referred to as:
Nitrate → Nitrite → Nitric Oxide
Nitric oxide plays an important role in the cardiovascular system, where it can influence blood-vessel tone and may facilitate vasodilation, meaning blood-vessels relax and widen, which is why researchers have shown interest in foods low in nitrate such as beetroot products.
How May Beetroot Nitrate Cause Blood-Vessels to Relax?
Imagine your blood-vessels as tubes of varying sizes through which blood is circulated throughout the body.
When blood-vessels are able to relax, they are more efficient at passing blood through them. In this instance, nitric oxide is one of the body's natural signalling molecules that may help to regulate this process.
Dietary nitrate provides a route for increasing nitric oxide availability through the nitrate-nitrite-nitric oxide pathway. Researchers therefore study nitrate-rich foods such as beetroot to understand whether they can influence vascular function and cardiovascular risk factors.
This does not mean that eating beetroot automatically prevents heart disease. Cardiovascular health depends on many factors, including blood pressure, cholesterol, physical activity, smoking, body weight, sleep, genetics and overall dietary pattern.
What Does Research Say About Blood Pressure?
Blood pressure is one of the areas where beetroot nitrate has been studied most closely.
A systematic review and meta-analysis of randomized trials involving people with arterial hypertension found that nitrate from beetroot juice was associated with a reduction in systolic blood pressure of about 4.95 mmHg compared with control.
The analysis did not find a statistically significant reduction in diastolic blood pressure. The researchers included seven studies involving 218 participants.
Another systematic review of beetroot juice trials reported reductions in both systolic and diastolic blood pressure, although the magnitude of the effect varied with factors such as dose and study duration.
These findings are promising but they should be interpreted carefully. The studies were generally testing beetroot juice or controlled nitrate intake, not ordinary servings of packaged beetroot chips.
Beetroot Nitrate and Endothelial Function
The endothelium is the thin layer of cells lining your blood vessels. Healthy endothelial function is important for normal circulation and cardiovascular health.
A systematic review and meta-analysis of randomized trials found that inorganic nitrate and beetroot supplementation were associated with improved measures of vascular function. The researchers included 12 trials with 246 participants.
More recent evidence also continues to investigate this relationship. A 2026 systematic review and meta-analysis of 13 randomized trials found that inorganic nitrate was associated with improved flow-mediated dilation.
A measure commonly used to assess endothelial function. However, the researchers also reported high variability between studies, so the results should not be interpreted as proof that nitrate supplementation will have the same effect in everyone.
Why Is Nitric Oxide Important for Cardiovascular Health?
Nitric oxide has several important roles in vascular biology.
It can help:
- Regulate blood-vessel relaxation
- Support normal blood flow
- Influence vascular tone
Contribute to healthy endothelial function
Dietary nitrate is intriguing because it can be a source of nitric oxide through a pathway that parallels the body's own nitric-oxide-producing enzymes. Beetroot and leafy vegetables are significant dietary sources of nitrate.
But nitric oxide is only one of many determinants of cardiovascular health. A single food cannot substitute for an overall heart-healthy lifestyle.
Does Eating Beetroot Give the Same Benefits as Beetroot Juice?
Not necessarily. This is an important point when talking about research on beetroot.
Many of the clinical studies are on beetroot juice, concentrated beetroot products or on specific amounts of nitrate. The amount of nitrate depends on the variety of beetroot, growing conditions, processing and serving.
Fresh beaten whole beetroot has other constituents, including fiber and plant compounds. Packaged beetroot 'snacks' may have a different nutrition profile because of processing, cooking, drying, oil, seasoning and serving size.
So it would be wrong to say that a research study on beetroot juice implies that eating a certain amount of beetroot chips would give the same cardiovascular benefit.
What About Beetroot Chips?
Beetroot chips are a convenient way to consume a beetroot-based snack but they should not be considered as a medical treatment or as a direct replacement for beetroot products used in clinical research studies.
When you go to the store, consider cutting the tray of pre-packaged beetroot chips in the middle of the bag and use a highlighter to mark the important details:
- Ingredients
- Nutrition facts
- Serving size
- Sodium content
- Seasonings or added oils
- Storage method
How the snack will be prepared will determine the overall nutritional quality.
If you are specifically looking for nitrate-rich foods, the best scientific evidence you can currently come across deals with nitrate-rich vegetables, beetroot juice and controlled nitrate supplementation rather than specific studies of commercial beetroot chips.
What Heart-Healthy Eating Looks Like
Heart-healthy eating is about many foods. Not a single food. The American Heart Association's 2026 dietary guidance is about overall dietary patterns that promote cardiovascular health and help reduce the risk of cardiovascular disease.
You could probably fit beetroot into such a varied diet with all the other nutrient-rich foods including vegetables, fruits, whole grains, legumes, nuts and seeds.
This is more useful than making heart health through a single nutrient or food.
Are Dietary Nitrates Safe?
Dietary nitrate commonly found in vegetables does not automatically trigger the same worry as in nitrate in other foods.
Vegetables offer nitrate together with a host of other nutrients and plant silences. Indeed, nitrate-dense vegetables have been used in studies of diets linked to cardiovascular benefit.
Nonetheless, people who have underlying health conditions or who are taking medication to lower blood pressure must not use beetroot products to substitute prescribed medication. A substantial

Beetroot is a nitrate-rich vegetable and research suggests that beetroot-derived nitrate may influence blood pressure and vascular function. However, cardiovascular health depends on the overall diet and lifestyle.
Final Thoughts
Dietary nitrate is one of the most interesting compounds found naturally in beetroot. Scientific research suggests that the nitrate-nitrite-nitric oxide pathway can influence vascular function and may help reduce systolic blood pressure in certain populations.
At the same time, it is important to keep the evidence in perspective. Much of the research has focused on beetroot juice or controlled nitrate supplementation, not packaged beetroot chips.
So, enjoy beetroot as part of a varied, balanced diet but don't treat beetroot chips or any single food as a cure for high blood pressure or heart disease.
The best approach to cardiovascular health remains a combination of a nutritious dietary pattern, regular physical activity, healthy habits and appropriate medical care when needed. Explore SNACKMAN Masala Beetroot Chips
