VFCore LS — L-Lysine 250mg Supplement for Cats

Feline Herpesvirus Type 1 (FHV-1) is the most common viral cause of upper respiratory disease in cats — and one of the most frustrating. Once a cat is infected, the virus never truly leaves. It establishes lifelong latency in the trigeminal nerve, then reactivates whenever the cat is stressed: a vet visit, a new pet in the home, boarding, illness, even a change in routine. Each flare-up brings the same painful symptoms — sneezing, nasal discharge, red and watery eyes, sometimes corneal ulcers and skin lesions. There is no cure. But there is a way to keep the virus quiet.

VFCore LS is built on a well-established veterinary principle: L-Lysine and arginine compete for the same cellular pathways, and the herpesvirus needs arginine to replicate. By increasing dietary lysine, the virus is starved of the building blocks it needs to make copies of itself — meaning fewer flare-ups, milder symptoms when they do occur, and reduced viral shedding to other cats in the household.

Each 12g lickable sachet of VFCore LS delivers 250mg of L-Lysine — the dose used across multiple veterinary studies (Glaze 2002; Nasisse 2002; Powell 2002; Griffies 2002; August 2007) for both treatment of active FHV-1 infections and prevention of recurrence. For cats with recurrent ocular FHV-1 infections, recommended daily dosing reaches 500mg twice daily, and VFCore LS is built to flexibly meet this dose with 1–4 sachets daily depending on the cat's age, weight, and clinical severity.

But VFCore LS is not just lysine. The formula is layered with three additional clinically meaningful ingredients. Yang® is a synergistic dual-yeast complex from Saccharomyces cerevisiae and Cyberlindnera jadinii — its specific genome and physical structure activates immune receptors (Dectin-1, MBR, TLR2) more efficiently than standard yeast derivatives, supporting natural self-defence and balanced gut microflora. Melofeed SOD is a French freeze-dried melon juice concentrate naturally rich in Superoxide Dismutase — the body's primary antioxidant — that scavenges free radicals 1,000,000× more effectively than standard antioxidative agents and boosts glutathione peroxidase activity by 41.8%. This is critical for cats fighting viral inflammation. Finally, FOS Prebiotic (fructooligosaccharides) supports gut bacterial balance, immunity, and stool consistency — important for stressed cats whose digestion often suffers alongside FHV-1 flare-ups.

The tuna and salmon meat base makes VFCore LS one of the most palatable lysine formats available. Cat owners know how impossible it is to give a cat anything they don't want — pills get spat out, powders get refused, capsules get stuck in fur. The lickable paste delivers the full clinical dose in a format cats genuinely accept, often lapping it directly off a finger or plate.

VFCore LS is recommended across multiple clinical scenarios. For active FHV-1 infection, the formula helps reduce viral load and ease respiratory and eye symptoms during a flare-up. For cats with recurrent latent infections, daily lysine helps control reactivation under stress and reduces severity when symptoms do return. For shelter and multi-cat home environments — where viral shedding and transmission are major concerns — regular lysine supplementation reduces outbreak risk across the colony. And for cats experiencing herpes-related skin lesions or ulcers, VFCore LS supports healing alongside any topical or systemic veterinary treatment.

The Lyra Division is a therapeutic supplement line developed for veterinary recommendation. VFCore LS is formulated to clinical lysine dosing standards rather than the inadequate doses found in most over-the-counter feline lysine products on the Indian market.

For pet parents whose cats experience recurring sneezing fits, watery eyes during stress, or have been diagnosed with FHV-1, VFCore LS offers a daily, evidence-based, easy-to-administer way to keep the virus in check — for life.

Pair with VFCore Feline Vitality for daily multi-nutrient support, or with VFCore BIO during stress periods to support gut immunity simultaneously.
