Who should use L-arginine?

Most people do not need an L-arginine supplement, as the body usually produces enough L-arginine naturally.

However, the supplement has been shown in studies to be useful for testing growth hormone levels in people who may have hormone-related disorders and for treating urea synthesis disorders, coronary artery disease, angina, heart failure, critical illness, migraines, and claudication (cramping pain caused by poor circulation) from peripheral vascular diseases. Research is ongoing on the safety and effectiveness of these uses and others.

Talk to your doctor or pharmacist to help in deciding how helpful and safe L-arginine may be for you.
