Foods That Help the Body Make Nitric Oxide

3. Arugula

Arugula is one of the most concentrated sources of dietary nitrates among commonly available vegetables — even more so than spinach or kale. That makes it especially effective for supporting nitric oxide production, particularly when eaten raw.

Its sharp flavor and small serving size work in its favor: you don’t need much to get a measurable benefit. For people managing blood pressure or looking to support circulation through diet, arugula offers a quick, nutrient-dense addition.
