Foods That Help the Body Make Nitric Oxide

2. Spinach

Spinach is one of the most consistent leafy green sources of dietary nitrates — the compounds your body uses to produce nitric oxide. That’s part of what makes it especially valuable for supporting circulation and blood pressure through food.

Unlike some vegetables, spinach retains its nitrate content when lightly cooked, which makes it adaptable in everyday meals. It also brings the added benefit of iron, potassium, and fiber — nutrients that support vascular function more broadly.

That flexibility — combined with steady nitrate levels — makes spinach one of the most accessible ways to support nitric oxide through diet.
