Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to examine the effect of short-term L-Citrulline on central and peripheral blood pressure in healthy older adults. The main questions it aims to answer are:

* Does L-citrulline favorably affect blood pressure at rest and during exercise?
* Does L-citrulline favorably affect arterial stiffness?
* Does L-citrulline favorably affect muscle oxygenation at rest and during exercise?

Participants will be asked to consume L-citrulline and a placebo for six days and participate in the evaluation of their blood pressure, arterial stiffness, and muscle oxygenation before and after each intervention.

Researchers will compare L-citrulline and placebo groups to examine whether L-citrulline supplementation affects the above health parameters.
