Reduced oxidative stress improves nitric oxide bioavailability, which can help lower blood pressure.

“how oxidative stress reduces nitric oxide is through the production of superoxide anions which will combine with nitric oxide and reduce nitric oxide levels to form the harmful and toxic peroxy nitrite essentially um how high intakes of omega-6 seed oils you know reduces nitric oxide is through oxidative stress so there's an increase in superoxide anions which will combine with nitric oxide to form the toxic peroxy nitrite and thereby you are both promoting oxidative stress and reducing nitric oxide levels”
