The Claim
Microencapsulated watermelon rind containing 4 grams of L-citrulline does not significantly alter tissue oxygen saturation (StO2) in healthy young adults during the 120 minutes following ingestion, despite improving endothelial function.
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 4 grams of L-citrulline from microencapsulated watermelon rind does not change tissue oxygen levels in healthy young adults over two hours after ingestion, but it does improve blood vessel function.
See the scientific wording
Microencapsulated watermelon rind containing 4 grams of L-citrulline does not significantly alter tissue oxygen saturation (StO2) in healthy young adults during the 120 minutes following ingestion, despite improving endothelial function.
After ingestion, L-citrulline is absorbed and turned into L-arginine in the kidneys, which the blood vessel lining uses to make nitric oxide. Nitric oxide causes blood vessels to widen, improving blood flow, but this does not increase the amount of oxygen reaching the tissues in healthy young adults.
What the research says
1 studyEating this special watermelon rind powder makes blood vessels relax better, but it doesn’t change how much oxygen gets to the tissues in healthy young people within two hours.
