Tomlyn Immune Support L-Lysine Powder Cat Supplement is a veterinarian formulated supplement that support your cat’s immune system, respiratory and eye health. Taste tested and loved by cats and kittens, safe and effective for cats of all ages.
As with any supplement, cat owners should consult with theirveterinarian or other animal care expert before giving their catsL-Lysine. Although the supplement is believed to be generally safe foruse in most cats with FVR, a trusted professional who is familiar withan individual animal's medical history and physical condition may havesuggestions for specific L-Lysine dosages and formulas.
While lysine is an herbal remedy readily available at natural foodstores, occasionally lysine supplements contain preservatives. Thepreservative "propylene glycol" is a dangerous compound for cats. Catswho have ingested propylene glycol have been shown to experience sideeffects such as blood reactions. Always choose all natural ingredientswhen selecting a brand of l-lysine supplement to treat feline herpesand cat conjunctivitis. Cat herpes, otherwise known as rhinotracheitis, is an upper respiratory illness that can also potentially affect the eyes. It is an airborne virus, and because of how easily cat herpes spreads, cats that live with other cats in the same household are the most at risk. While L-Lysine supplements are not a direct cure for cat herpes, it has been clinically shown to both decrease a cat's risk of contracting the rhinotracheitis virus, and slow the growth of the infection.Although some antiviral medications developed for humans infected with HSV-1 can be used safely in cats and are effective against FHV-1, no medications or vaccines reduce establishment of latency or frequency of viral reactivation.1 In addition, other human antiviral drugs are ineffective against FHV-1, toxic to cats, expensive, or cannot be administered for protracted periods. This has led to investigation of adjunctive antiviral therapies, such as l-lysine therapy, that are safe, effective, and inexpensive and can be given long term.An uninfected cell usually does not use much of a particular amino acid called arginine, while cells that are infected use a lot of it to make more copies of the virus. The cell's natural chemical process that uses arginine is limited by the quantity of L-Lysine (another amino acid) that's available. By giving daily L-Lysine supplements to your cat, you increase the quantity of L-Lysine available for the cat's cells to use, which means that the cell uses more arginine for its natural functions. This leaves less arginine available for the production of the cat herpes virus, thereby slowing the growth of the infection.In Vivo Research
Results of 2 independent in vivo studies have supported the clinical use of l-lysine in cats. In the first of these studies,4 8 FHV-1-naive cats were administered 500 mg of lysine Q 12 H PO beginning 6 hours before, and continuing for 3 weeks after experimental inoculation with FHV-1. Lysine-treated cats had significantly less severe conjunctivitis than cats that received placebo.Thus, the safety and efficacy of l-lysine incorporated into cat food have been studied. Results of an initial safety trial were encouraging.6 Cats fed a diet supplemented with up to 8.6% (dry matter) l-lysine showed no signs of toxicity, had normal plasma arginine concentrations, and had normal food intake. Mean plasma lysine concentration of these cats was increased to levels similar to that achieved with bolus administration. In a subsequent study,7 25 cats with enzootic upper respiratory tract disease were fed a diet supplemented to 5.1% lysine for 52 days while subjected to rehousing stress (which is known to cause viral reactivation).
