Study Purpose

The STAMP research study will evaluate the amino acid Arginine and its effects on the process our bodies go through to convert food into energy (metabolism). This study will examine the effects of Arginine on hormones in the blood to determine if arginine can benefit warfighter performance.

Arginine is an essential amino acid found in various foods like turkey, pork, and chicken. Arginine is thought to help improve blood flow and immune function.

About the Study

Participants will visit the Pennington Biomedical Outpatient Clinic for a screening visit to determine eligibility. Once enrolled, participants will be provided with meals for 6 days during the study and will drink beverages both with and without the amino acid, arginine.

This study will provide new information that will help researchers understand how Arginine may help improve warfighter fatigue, performance, and stress levels.
