Top Fruits Rich in Lysine and Balanced Arginine for Better Health

Lysine and arginine are essential amino acids that play opposite roles in viral replication and immune health. Lysine is known to help inhibit the growth of viruses like herpes simplex that cause cold sores, while arginine can promote viral replication.
