Why Do Cats Need Lysine Support
1. What is lysine
Lysine is an essential amino acid that cats cannot synthesize on their own. It must be obtained from food or nutritional supplements to maintain normal bodily functions.
2. Core benefits for cats
Fight feline herpesvirus (FHV-1) — This is the primary reason for lysine supplementation. Feline herpesvirus causes feline viral rhinotracheitis, leading to runny nose, watery eyes, sneezing, conjunctivitis and upper respiratory infections. Lysine inhibits the replication of the herpes virus, relieving symptoms and reducing recurrence. It is especially necessary for kittens, shelter cats and stressed felines.
Strengthen immune system — Lysine participates in the production of antibodies and immune cells. It improves cats’ disease resistance, helping them resist bacterial and viral infections, and aids recovery after illness.
- Maintain tissue & body health: Promotes the repair of respiratory tract, eye and mucosal tissues.
- Supports normal growth for kittens, and maintains skin, fur and muscle health for adult and senior cats.
- Assists nutrient absorption and protein metabolism.
