L Lysine for Cats – the most important at a glance

L-Lysine is a dietary supplement for cats, known to boost their immune system and combat feline herpesvirus. This essential amino acid is not naturally produced by a cat’s body, but is vital in lysine’s collagen production and calcium absorption. L-Lysine products for cats come in different forms, including powder, gel, treats, and capsules, each with varying strengths (usually ranging from 250mg to 500mg per dose). While all L-Lysine products for cats essentially aim to improve feline health, they differ in terms of their ease of administration, taste, and price. Some cats may prefer the taste of certain lysine treats, while others may find it easier to consume the supplement when it’s mixed into their food with lysine powder or gel. Always remember to consult a vet for the suitable quantity and frequency for your cat’s breed, size, and health condition.
