Foods That Help the Body Make Nitric Oxide

4. Garlic

Garlic supports nitric oxide in a different way. Instead of supplying nitrates, it helps the body make its own nitric oxide — a process tied to better blood flow and circulation.

This effect is linked to sulfur compounds like allicin, which also give garlic its strong smell. These compounds may help nitric oxide stay active longer by protecting it from breaking down too quickly.

For the best effect, garlic should be crushed or chopped and allowed to sit briefly before cooking — a simple preparation tweak that preserves more of its active compounds.
