In hypertensive postmenopausal women, increases in blood flow to the forearm during hand exercise after taking L-citrulline are linked to improved dilation of the brachial artery, suggesting that the lining of blood vessels plays a role in how blood flow responds to exercise.

L-Citrulline Supplementation Improves Arterial Blood Flow and Muscle Oxygenation during Handgrip Exercise in Hypertensive Postmenopausal Women

Randomized Controlled Trial

Human

2024 Jun 19

Taking L-citrulline helped improve blood flow in the arms of women with high blood pressure, and this improvement was linked to better function of the blood vessel lining—meaning healthier blood vessels helped the arms get more blood during exercise.
