- Dosing considerations for Lysine.
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.
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).
