Improve vascular function

What this outcome means

Vascular function is how well your blood vessels widen, narrow, and respond as blood moves through your body during rest and effort. On DoseRank it maps to a defined health outcome built from human studies on flow-mediated dilation, arterial stiffness, and endothelial reactivity – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Stiffening with ageOlder arteries that have grown less elastic and slower to respond.

Sedentary circulationLong sitting days and little movement that leave vessels sluggish.

Watching the numbersPeople tracking blood pressure and vascular markers at routine checkups.

Stack buildersAlready taking supplements such as Grape Seed Extract or Trans-Resveratrol and want the dose right.
