L-Lysine is an essential amino acid that plays a powerful role in immune support, collagen production, and tissue repair. Your body can’t produce it on its own, so it needs to come from food or supplements.
 
It’s known for helping fight off cold sores (thanks to its antiviral properties), supporting wound healing, and even promoting healthy skin by boosting collagen synthesis.
 
Stronger immunity. Healthier skin. Better recovery.
