L-Arginine is a glucogenic amino acid.

It is often supplemented for good circulation and cardiovascular health. Peer Reviewed Professional Journals: Ceremuzynski, L., et al. Effect of supplemental oral L-arginine on exercise capacity in patients with stable angina pectoris. Am J Cardiol. 80:331-333, 1997.

This double-blind study involved 22 people with stable angina. Each subject underwent an exercise stress test up to the point where changes on ECG indicated heart muscle strain. For three days, half the group received placebo while the other half received 2,000mg of arginine per day. The exercise stress test was then repeated.

Patients in the placebo group experienced an increase in exercise time of approximately one minute. The patients receiving arginine increased the time that they could exercise without experiencing heart muscle strain by almost three minutes and ECG abnormalities were less in the arginine group compared to the placebo group.
