The Claim
Improvements in forearm blood flow and vascular conductance during handgrip exercise following L-citrulline supplementation are positively correlated with improvements in brachial artery flow-mediated dilation in hypertensive postmenopausal women, indicating that endothelial function mediates exercise-induced vasodilation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.

What the research says
1 studyTaking 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.
