The ratio between two amino acids in your diet may be quietly affecting your ability to fight off an entire family of viruses.
Lysine has a well established antiviral effect particularly against herpes family viruses. But when arginine intake significantly outpaces lysine intake that antiviral protection gets diminished. This matters for more than just cold sores.
The herpes family includes Epstein Barr virus, cytomegalovirus, herpes zoster which causes shingles, and human herpesvirus six and seven. If any of these are chronically reactivating in your system, your lysine to arginine ratio may be one of the most overlooked dietary factors contributing to it.
Small nutritional shifts can have significant antiviral consequences.
