Short answer: To improve vascular health, protect the endothelium, the thin cell layer lining every blood vessel. The habits with the best evidence are not smoking, keeping blood pressure in the normal range (under 120/80 mm Hg), getting at least 150 minutes of moderate aerobic activity a week, and eating a vegetable-heavy, lower-sodium diet that naturally supplies dietary nitrate. Beet juice is the best studied nitrate food, but it complements these basics rather than replacing them.
Key Takeaways
- Vascular health is mostly about the endothelium, which releases nitric oxide to relax and widen blood vessels.
- Smoking, high blood pressure, high cholesterol and high blood sugar are the main factors that damage artery walls and start plaque buildup, according to the NHLBI.
- The American Heart Association recommends at least 150 minutes a week of moderate aerobic activity plus muscle strengthening on at least 2 days.
- In a 2008 human study, 500 mL of beetroot juice lowered systolic blood pressure by about 10 mm Hg at its peak, and the effect depended on swallowing saliva, which shows how much mouth bacteria matter.
- Nitrate content varies enormously between foods: EFSA reported median levels from 1 mg/kg (peas, Brussels sprouts) up to 4,800 mg/kg (rocket, also called arugula).
- No supplement replaces blood pressure control, exercise and quitting tobacco. If you take blood thinners or blood pressure medication, talk to your doctor before adding concentrated nitrate products or herbal supplements.
What Vascular Health Means (and Why the Endothelium Matters)
Your vascular system is the network of arteries, veins and capillaries that carries blood, oxygen and nutrients to every tissue. “Vascular health” describes how well those vessels do their job: staying flexible, opening and narrowing on demand, and keeping their inner surface smooth and free of plaque.
The key structure is the endothelium, a single layer of cells lining the inside of every vessel. It is not a passive pipe wall. Healthy endothelial cells produce nitric oxide, a signaling gas that tells the surrounding smooth muscle to relax so the vessel widens and blood flows more easily. The NIH Office of Dietary Supplements describes nitric oxide as a compound that dilates blood vessels and improves oxygen and nutrient delivery to muscle.[1] Doctors measure this ability with tests such as flow-mediated dilation, which is why “endothelial function” is a common research term for vascular health.
How blood vessels get damaged
The NHLBI explains that plaque buildup (atherosclerosis) starts with damage to the arteries. High blood pressure can damage artery walls, high blood sugar can damage the inner layers of the arteries, and inflammatory diseases can injure blood vessels. Once the lining is damaged, inflammatory cells gather there, cholesterol and cell waste collect, and plaque forms.[2] The NHLBI names high blood pressure, unhealthy cholesterol and smoking as key risk factors that can trigger the start of plaque buildup, and links physical inactivity with unhealthy cholesterol levels.[2]
That list is your roadmap. Improving vascular health mostly means removing what injures the endothelium and adding what helps it work.

How to Improve Vascular Health: 7 Evidence-Based Steps
1. Stop smoking and avoid tobacco smoke
Smoking is one of the risk factors the NHLBI says can trigger plaque buildup in the arteries.[2] No food, workout or supplement offsets continued smoking. If you smoke, quitting is the single biggest change you can make for your blood vessels. Ask your doctor about cessation support; combining counseling and medication usually works better than willpower alone.
2. Know and control your blood pressure
High blood pressure physically strains artery walls. The American Heart Association classifies readings as follows:[3]
| Category | Systolic (top number, mm Hg) | Diastolic (bottom number, mm Hg) |
|---|---|---|
| Normal | Less than 120 | and less than 80 |
| Elevated | 120 to 129 | and less than 80 |
| Stage 1 hypertension | 130 to 139 | or 80 to 89 |
| Stage 2 hypertension | 140 or higher | or 90 or higher |
| Severe hypertension or emergency | Higher than 180 | and/or higher than 120 |
A reading above 180/120 with symptoms such as chest pain or trouble speaking is an emergency. Home monitoring is cheap and gives your doctor far better data than a single office reading. If your numbers are high, treatment decided with your clinician comes first; lifestyle steps support it.
3. Move most days
The American Heart Association recommends at least 150 minutes a week of moderate-intensity aerobic activity (or 75 minutes of vigorous activity), plus moderate to high intensity muscle strengthening on at least 2 days a week. It adds that being active at least 300 minutes a week brings even more benefit, and that even light activity offsets some of the risks of sitting.[4] Among the benefits it lists are a lower risk of heart disease, stroke, type 2 diabetes and high blood pressure. Brisk walking, cycling and swimming all count.
4. Eat the DASH way and watch sodium
The NHLBI DASH eating plan emphasizes vegetables, fruits and whole grains, plus fish, poultry, beans, nuts and vegetable oils, while limiting saturated fat, sugary drinks and sweets. It sets a sodium target of 2,300 mg a day and notes that 1,500 mg lowers blood pressure even further.[5] A plate built this way also happens to be rich in dietary nitrate, which is the next step.
5. Add nitrate-rich vegetables
Inorganic nitrate from vegetables is converted in the body, largely through nitrite, into nitric oxide.[1] Mouth bacteria play an essential role. In a 2008 study published in Hypertension, 14 volunteers drank 500 mL of beetroot juice. Systolic blood pressure fell by a peak of 10.4 mm Hg about 2.5 hours later, and diastolic pressure by about 8 mm Hg at 3 hours. In a separate group of 10 people, the juice, taken 2 hours beforehand, prevented a temporary drop in endothelial function caused by restricting blood flow to the arm. When 6 participants spat out their saliva instead of swallowing it, the rise in plasma nitrite and the blood pressure drop did not happen.[6] These were small, short-term studies in healthy volunteers, so they show a mechanism, not a long-term treatment.
For a deeper look at the juice itself, see our beet juice benefits guide, and for a broader food and lifestyle list, read how to increase nitric oxide naturally.
6. Manage blood sugar and cholesterol
Because high blood sugar and unhealthy cholesterol both feed plaque formation,[2] routine blood work matters. Know your fasting glucose or HbA1c and your lipid panel, and follow up with your doctor if they drift. The same habits above (activity, DASH-style eating, no tobacco) move all of these markers in the right direction.
7. Treat it as a long game
Vascular changes build over years. A single beet shot or one good week of workouts will not undo decades of smoking or untreated hypertension, but consistent habits sustained over months and years are what the evidence supports.
Nitrate-Rich Foods: What the Data Shows
Nitrate levels depend on the vegetable, the soil, the season and growing conditions, so any number is an average. The European Food Safety Authority (EFSA) reviewed nitrate in vegetables in 2008 and found median levels ranging from 1 mg/kg in peas and Brussels sprouts to 4,800 mg/kg in rocket, with fruit around 10 mg/kg.[7] The NIH Office of Dietary Supplements reports that beetroot juice products vary widely too.[1]
| Food | Sourced nitrate data | Practical note |
|---|---|---|
| Rocket (arugula) | Median about 4,800 mg/kg, the highest EFSA reported[7] | A handful in salads adds a lot of nitrate; EFSA estimated that more than about 47 g at median levels would exceed the acceptable daily intake on its own |
| Beetroot juice | 500 mL (about 2 cups) supplies roughly 310 to 682 mg nitrate, depending on the product[1] | The best studied nitrate food; most research used it 2.5 to 3 hours before exercise |
| Other leafy greens (spinach, lettuce) | EFSA identifies people eating large amounts of leafy vegetables as the group with the highest nitrate exposure[7] | Easy daily source; amounts vary by season and growing method |
| Mixed vegetables | 400 g of mixed vegetables at median levels provides about 157 mg nitrate per day[7] | A realistic target for most people eating a DASH-style diet |
| Fruit | About 10 mg/kg[7] | Low in nitrate but supplies potassium and fiber that support healthy blood pressure |
| Peas, Brussels sprouts | Median about 1 mg/kg[7] | Healthy foods, but not meaningful nitrate sources |
The ODS notes that about 2 cups of beetroot juice per day for several weeks raised no safety concerns and still supplies less than half the nitrate of a diet rich in vegetables and fruits.[1] EFSA concluded that, for the general population, the benefits of eating vegetables outweigh the risks from their nitrate.[7]
Safety: Who Should Talk to a Doctor First
- People on blood pressure medication. Beetroot juice lowered blood pressure in the 2008 study.[6] If you already take medication, large daily amounts of concentrated beet products could add to its effect. Check with your doctor or pharmacist.
- People on blood thinners or antiplatelet drugs. The same study found that beetroot juice reduced platelet aggregation for a few hours after drinking it.[6] This is not dangerous for most healthy people, but it is worth mentioning to your clinician if you take anticoagulants.
- Anyone with leg pain on walking, chest pain or shortness of breath. These can signal artery disease and need medical evaluation, not self-treatment.
- Beeturia. Pink or red urine after beets is caused by beet pigments and, according to the ODS, is not a safety concern.[1]

Frequently Asked Questions
What is the fastest way to improve vascular health?
There is no shortcut, but the changes with the largest payoff are quitting smoking and getting high blood pressure under control with your doctor. Regular aerobic exercise and a vegetable-rich, lower-sodium diet add to that. Beet juice can lower blood pressure for a few hours,[6] but lasting change comes from habits kept over months.
What foods are good for blood vessels?
Vegetables, fruits, whole grains, beans, nuts, fish and vegetable oils, the backbone of the DASH plan.[5] Leafy greens such as rocket and spinach and beetroot are especially rich in dietary nitrate, which the body can convert to nitric oxide.[1][7]
Does exercise improve endothelial function?
Regular physical activity lowers the risk of heart disease, stroke, type 2 diabetes and high blood pressure,[4] all of which are tied to blood vessel damage. Aim for at least 150 minutes of moderate activity a week plus strength work on 2 days, as the American Heart Association recommends.
How much beet juice should I drink for nitric oxide?
Most studies used about 500 mL (2 cups) a day, which supplies roughly 310 to 682 mg of nitrate depending on the product.[1] Many people simply eat beets and leafy greens a few times a week instead. If you take blood pressure medication or blood thinners, ask your doctor before drinking concentrated beet juice daily.
Can vascular damage be reversed?
Some risk factors, like blood pressure and cholesterol, respond well to treatment and lifestyle change, which can slow further damage. How much existing plaque can change depends on the person and should be discussed with a cardiologist or vascular specialist, who can order the right tests.
