Swanson Lysine 500 mg 100 capsules.

Swanson L-Lysine 500mg provides pure free-form L-lysine, an essential amino acid that must be obtained through food or supplements as the human body cannot synthesize it.

Lysine is an important building block for collagen and bone matrix proteins, supports calcium absorption, and competes with arginine in inhibiting the replication of the herpes simplex virus – making it a popular supplement for managing the frequency and severity of cold sores.

For best results, especially for cold sores, take 2-4 capsules (1-2 g) daily between meals. For general health, one capsule daily is sufficient. 100 capsules per bottle.
