Metagenics Lysine Shield

Metagenics Lysine Shield combines high-dose Lysine, Vitamin C, Zinc and Astragalus — delivering targeted nutritional support to help reduce the occurrence of facial cold sores, support skin repair and wound healing, and strengthen immune resilience against environmental stressors.

Key ingredients

• Lysine Hydrochloride: The hero ingredient for cold sore support — amino acid that helps reduce the occurrence of facial cold sores by competing with arginine, the amino acid that the herpes simplex virus needs to replicate
• Ascorbic Acid (Vitamin C): High-dose vitamin C supporting immune system function, skin integrity and wound healing — working synergistically with Lysine and Zinc for comprehensive skin and immune support
• Zinc: Supports healthy skin repair, wound healing and immune function — an essential mineral for both the physical barrier of the skin and the immune response to viral triggers
• Astragalus Root: A well-researched immune tonic herb that helps the body cope with environmental and physical stressors — adding an adaptogenic immune layer to this targeted cold sore formula
