L-Lysine
L-Lysine: your antiviral peacekeeper.
L-lysine is an essential amino acid that the body can’t make on its own—meaning we must obtain it through diet or supplementation. Known for its antiviral properties, especially against herpes-family viruses, L-lysine acts like the immune system’s peace negotiator: blocking viral activity, calming inflammatory flare-ups, and supporting tissue repair while the immune system does its job.
Here’s why we love L-lysine for immune health:
Inhibits viral replication, particularly for herpes simplex viruses (cold sores & similar viral irritations).
Competes with arginine, an amino acid needed for viral replication—essentially starving certain viruses of the resources they require to multiply.
Supports collagen formation and tissue repair, helping mucosal and epithelial tissues recover more quickly from infection or inflammation.
May reduce frequency, severity, and healing time of recurrent viral outbreaks, especially under stress or immune strain.
Supports antibody production, strengthening immune system readiness.
Well tolerated for both short-term immune defense and regular preventive dosing, especially during travel or high-stress seasons.
Evidence-based research findings:
L-lysine supplementation can significantly reduce occurrence and duration of herpes simplex outbreaks.
Lysine-to-arginine ratio in diet influences viral reactivation rates.
L-lysine may support favorable mucosal immune responses and tissue healing.
Its antiviral activity is enhanced when combined with zinc, vitamin C, and bioflavonoids.
L-lysine supplementation has demonstrated immune-supportive benefits in individuals prone to recurrent viral infections.
