Natural Factors L-Lysine delivers 1000mg of this essential amino acid to support immune function and help reduce cold sore recurrence. Unlike your body's other amino acids, L-lysine cannot be produced internally—you must get it from food or supplements. This pharmaceutical-grade formula ensures you get the therapeutic amounts your immune system and tissues actually need.
