What is 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.
Possibly Effective for...
- Cold sores (herpes simplex labialis). Research suggests that lysine seems to reduce cold sores when taken by mouth and also when applied as a cream to the skin. However, some research suggests that it does not reduce the severity or recurrence of cold sores.
Insufficient Evidence to Rate Effectiveness for...
- Canker sores. Early research suggests that taking 500 mg of lysine daily prevents canker sores and 4000 mg daily decreases the length of canker sores.
- Diabetes. Some evidence shows that taking lysine daily for 2 months does not affect blood sugar levels in people with diabetes. However, other early research suggests that taking lysine twice daily for 2 months decreases blood sugar levels compared to before treatment in diabetes patients.
- Stress. Early research suggests that eating wheat that contains added lysine reduces stress in females and anxiety in males.
- Improving athletic performance.
More evidence is needed to rate the effectiveness of lysine for this use.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
