Currently I'm giving my cat [emoji]128049[/emoji] the GNC Lysine chewables. He likes them but I'm not to hip on the extra additives. I'm sure a more pure form would be better .
To boost immunity mainly. Just found out he has a small asthma problem too. Noney got a really bad cold which compounded with his asthma, poor guy. Since then he's much better. Have him on GNC Lysine and Amazapet for the asthma. I noticed he sneezes here and there also. So just want to keep colds and allergies at bay. Also have a high end air purifier due to arrive this week.
I haven't try the now brand but if i remember right other members said it last a long time. If you can give him half in the morning and half in the afternoon or night
