Medical term:

lysine


Lysine is an amino acid (building block of protein). People use it to make medicine. Lysine is used for preventing and treating cold sores (caused by the virus called herpes simplex labialis). It is taken by mouth or applied directly to the skin for this use. Lysine is also taken by mouth to improve athletic performance. How does it work? Lysine seems to prevent the herpes virus from growing.

Dosing

The following doses have been studied in scientific research:

BY MOUTH:

  • For cold sores (herpes simplex labialis): 1000 mg daily for 12 months and 1000 mg three times daily for 6 months.
APPLIED TO THE SKIN:
  • For treating cold sores (herpes simplex labialis): a specific combination of lysine plus zinc oxide and 14 other ingredients (Super Lysine Plus +) applied every 2 hours for 11 days has been used.
