Ways To Add Dietary Nitrates to Your Diet

Dark green leafy vegetables are some of the most studied foods in nutrition research. They show up in studies linked to better cardiovascular health, stronger lung function, and improved eye health. Much of that credit goes to antioxidants and carotenoids, but there is another reason they perform so well: dietary nitrates.

Nitrates are the raw material your body uses to produce Nitric Oxide (NO), the molecule that relaxes blood vessels and supports healthy blood flow. People sometimes search for "nitrogen-rich foods" or "foods high in nitrogen" when what they actually want are foods high in nitrate, the nitrogen-containing compound that converts to NO. The more nitrate-rich foods you eat, the more building blocks your body has to work with.

Here are the best food sources of Nitric Oxide and practical ways to work them into meals you actually enjoy.

Benefits Of Eating Foods High In Nitrates

Dietary nitrates convert to Nitric Oxide through a pathway that works independently of the enzyme that declines with age. That makes them especially valuable for adults over 40 who are losing NO production through the body's primary route.

Supports Blood Flow

NO relaxes blood vessel walls and widens arteries, allowing blood to move with less resistance. More dietary nitrate means more raw material for that process.

Supports Healthy Blood Pressure

Research has shown that consistent intake of dietary nitrates from vegetables is associated with lower systolic blood pressure, supporting cardiovascular health over time.

Supports Energy and Recovery

When blood flow improves, oxygen reaches muscles and organs more efficiently. That translates to better endurance during activity and faster recovery afterward.

Supports Heart Health Long-Term

Healthy NO levels help arteries stay flexible and responsive rather than stiff and narrow. Eating nitrate-rich vegetables daily is one of the simplest ways to support vascular health as you age.

Top Dietary Nitrate Sources

Not all vegetables deliver the same amount. Here are the standouts, ranked by nitrate content per 100g of raw weight.

• Arugula: Up to 480 mg per 100g. The highest of any commonly available vegetable.
• Spinach: 250 to 350 mg per 100g. A versatile daily staple.
• Beetroot: 250 to 495 mg per 100g. The most studied food for Nitric Oxide.
• Celery: 150 to 260 mg per 100g. Easy to add as a snack or side.
• Butter leaf and romaine lettuce: 100 to 250 mg per 100g. Solid base for salads.
• Beet greens and Swiss chard: 150 to 400 mg per 100g. Often discarded, but packed with nitrate.
• Fresh basil and cilantro: Surprising herbs that contribute meaningfully when used generously.

Kale, despite its reputation, provides only about 27 mg per 100g, making it a strong source of other nutrients but a modest source of nitrate.

Simple Ways to Eat More Nitrate-Rich Foods

Knowing which foods contain nitrate is one thing. Actually eating enough of them every day is another. Here are practical ways to build the habit.

Blend It

Add a handful of fresh arugula or baby spinach to your morning smoothie. Combined with fruit, yogurt, or juice, the flavor blends in easily. Beet greens work well here, too.

Build Better Salads

Skip iceberg lettuce. Use arugula, spinach, butter leaf, or romaine as your base. A large mixed-green salad (roughly 150g) can deliver over 400 mg of dietary nitrate in a single sitting. Add fresh herbs like basil and cilantro for extra contribution.

Sprinkle It On

Arugula, spinach, and basil make excellent last-minute additions to homemade pizza, pasta, and grain bowls. Add greens during the last minute of cooking or toss them on top fresh.

Add Greens to Existing Recipes

You don't need new recipes. You need greens in the ones you already make.

• Stir baby spinach or arugula into soups and stews in the last few minutes of cooking.
• Fold spinach into omelets and scrambled eggs before serving.
• Toss beet greens into casseroles alongside other vegetables.
• Use flat-leaf parsley generously as a finishing herb on any savory dish.

Snack on Celery and Beets

Raw celery with hummus and roasted beet slices are easy, nitrate-dense snacks that require no cooking. Keep them prepped in the fridge for quick access.

When Food Alone Isn't Enough

Eating foods containing Nitric Oxide precursors is one of the best things you can do for blood flow. But hitting 300+ mg of dietary nitrate consistently every day takes planning, and the nitrate content in any given vegetable varies with soil, season, and storage.

Berkeley Life Nitric Oxide Supplement delivers the dietary nitrate equivalent of 7 oz of beetroot in two capsules, with the same standardized dose every day. Pair it with nitric oxide test strips to see whether food, supplementation, or the combination keeps your NO levels on track. Eat the greens, fill the gaps, and give your body what it needs to keep blood flowing.

Frequently Asked Questions

What foods are high in nitrates?

Arugula, spinach, beetroot, celery, butter leaf lettuce, beet greens, Swiss chard, and fresh herbs like basil and cilantro are among the richest options available in most grocery stores.

Where can I get dietary nitrates?

From the produce section. Dark green leafy vegetables and root vegetables like beetroot are the richest sources. A daily supplement can fill gaps when vegetable intake varies.

How do I get more nitrates in my diet?

Build salads with arugula and spinach as a base, add greens to smoothies, stir leafy vegetables into soups and eggs, and use fresh herbs generously as a finishing touch.

Are dietary nitrates good for you?

Yes. Dietary nitrates from vegetables convert to Nitric Oxide, which supports blood flow, healthy blood pressure, energy, and cardiovascular health. Vegetable-sourced nitrates are well studied and widely recommended.

What are dietary nitrates?

Dietary nitrates are naturally occurring compounds found in vegetables, especially leafy greens and beetroot. The body converts them into nitrite and then Nitric Oxide through the enterosalivary pathway.
