What is the best brand and form of Lysine for my cat?

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 .

The now brand is great

Thank you! My cat is 16lbs. Would the 1/4 tsp be sufficient?

Why you giving lysine? Is for herpes? To prrevent outbreaks? Or just want to boost immune system?

For flare ups or outbreaks, it 1000mg, for maintenance it 500mg a day, 250mg in the morning and 250mg at night

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.

Ok,1/4 is ok

Thank you for your input and knowledge! I will place an order for the NOW brand.

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

We use VitaCost brand.  I've used NOW brand in the past.

1/4 t = 500 mg

I actually buy from Vitacost. Thank you.
