The herpes virus needs an amino acid called arginine to wake up and replicate.
Without arginine, it can't activate. Can't attack. Can't cause flare-ups.
Lysine blocks arginine. Starves the virus of what it needs.
Think of it like this:
When lysine levels stay high, the virus stays asleep. Dormant. Harmless.
When lysine levels drop — missed dose, refused treat, spit-out gel — the virus finds its opening. Wakes up. Attacks.
That's why the ingredient was never the problem.
The problem was always consistency.
Treats your cat won't eat? Inconsistent levels. Virus wakes up.
Gels they spit out? Inconsistent levels. Virus wakes up.
Powders they taste? Inconsistent levels. Virus wakes up.
The only way to keep the virus asleep is to keep lysine levels consistent. Every single day. No gaps. No missed doses. No negotiations with a picky cat.
That's why format matters more than ingredient.
