L-Arginine and Cold Sores: An Important Warning

L-Arginine may trigger cold sore outbreaks in people prone to herpes simplex (HSV-1). The virus uses arginine for replication. If you get cold sores regularly, consult your doctor before taking MemoHoney or any supplement containing L-Arginine. This is a documented interaction, not a theoretical concern. See Mayo Clinic.
