    People with certain health conditions should not use L-arginine, including those with allergies, asthma, recent heart attack, low blood pressure, herpes infection, liver disease, and sickle cell disease. Talk to your doctor before using L-arginine if you have any of these conditions.

    No studies have proven the safety in using L-arginine while pregnant or nursing, so it is not recommended for pregnant or breastfeeding women.

    Children younger than 18 years of age should not take L-arginine because of a lack of research to support its safety in this population.

    Because L-arginine is a supplement, it is not as closely regulated by the Food and Drug Administration as medications are.
