The Claim
Four weeks of 10-gram daily L-citrulline supplementation increases muscle tissue oxygen saturation (TSI) by 1.61% and reduces deoxygenated hemoglobin (HHb) by 2.76 μM during handgrip exercise in hypertensive postmenopausal women, indicating improved oxygen delivery and reduced oxygen extraction in forearm muscle tissue.
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 leads to a small increase in oxygen levels and a decrease in deoxygenated hemoglobin in the forearm muscles of hypertensive postmenopausal women during handgrip exercise, suggesting changes in how oxygen is delivered and used in that tissue.

What the research says
1 studyThis study found that taking 10 grams of L-citrulline every day for four weeks helped women with high blood pressure get more oxygen to their forearm muscles during exercise, and their muscles didn’t have to work as hard to use it.
