The Claim
L-citrulline supplementation at a dosage of 10 g/day for 4 weeks reduces resting aortic systolic blood pressure by 4 mmHg in hypertensive postmenopausal women, independent of changes in aortic stiffness, indicating a direct effect on arterial tone.
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.
Taking 10 grams of L-citrulline daily for four weeks lowers aortic systolic blood pressure by 4 mmHg in postmenopausal women with hypertension, without altering aortic stiffness, suggesting a direct effect on blood vessel tone.
See the scientific wording
L-citrulline supplementation (10 g/day for 4 weeks) reduces resting aortic systolic blood pressure by 4 mmHg in hypertensive postmenopausal women, independent of changes in aortic stiffness, suggesting a direct vascular effect on arterial tone.
What the research says
1 studyThis study found that taking 10 grams of L-citrulline daily for a month lowered blood pressure in older women with high blood pressure, without changing how stiff their arteries were — meaning it likely helped their blood vessels relax directly.
