What is arginine?

ANSWER

Arginine, or L-arginine, is an amino acid that your body makes. As a supplement, it may help with several conditions, from migraines to inflammation. It's become popular, but most people seem to have enough arginine in their bodies already and there may not be much benefit from supplements.

Doctors may recommend that people with protein malnutrition, burns, infections, rapid growth, and other conditions take supplemental arginine.
