Review on Carlson L-Lysine Powder: 960 mg Free-Form Amino Acid for Healthy Tissue & Muscle Development, 3.53 oz (100 g) by Chris Kajzer

I have been using this product for my senior cats for many years. I have 5 live cats and they rarely get ARVI and when it does it usually doesn't spread or progress very, very easily. A cat was adopted at the age of 8 and suffered from chronic sneezing. After taking an L-lysine supplement for a year, she finally stopped her daily sneezing spells completely and hasn't gotten sick since we adopted her. I swear by this product and add a full scoop to every cat's breakfast. It is odorless and tasteless - some cats may not like its graininess so I dilute it in a few drops of water first before mixing it with canned food. I had no problem with one of the cats giving up. The cost of Revain is almost 40% less than what I paid for it at the vitamin store here in town.
