L-Lysine 500mg — Immune & Respiratory Support for Cats
PurePalsLab Formula #006 delivers a therapeutic dose of 500mg L-Lysine hydrochloride per chew. L-Lysine is an essential amino acid that competes with arginine — a compound required for feline herpesvirus (FHV-1) replication — providing targeted support for cats exposed to this ubiquitous pathogen.
Active Compound & Mechanism
| L-Lysine Hydrochloride 500mg | Competitive inhibitor of arginine utilization by FHV-1; supports reduced viral replication and symptom severity |
Clinical Context
Feline herpesvirus type 1 (FHV-1) is estimated to affect 80-90% of the global cat population. While many cats remain asymptomatic carriers, stress, illness, or immune suppression can trigger viral reactivation — manifesting as conjunctivitis, rhinitis, sneezing, and ocular discharge.
Research published in the American Journal of Veterinary Research demonstrated that cats supplemented with L-Lysine showed reduced severity of conjunctivitis and respiratory symptoms during FHV-1 flare-ups.
Dosing Protocol
Cats of all sizes: 1-2 chews daily. For optimal results, administer consistently each day. Fish flavor formulated for feline palatability.
Note on Quality
Our L-Lysine is USP-grade, verified for purity via HPLC analysis, and manufactured without artificial colors, flavors, or preservatives.
