NOW Foods L-Lysin 500 mg, 250 Kapseln (2er Pack)

I purchase many "NOW" products. Tried this lysine product on cats who take this supplement daily, vital for their compromised immune systems. Unfortunately, it did NOT work well, as with most other lysine brands. The cats started showing symptoms of their chronic infections a few days later. After putting them back on the other (more expensive brand) they went back to "remission".... Every family member takes 2,000 mg of lysine daily, so we rather pay a little more money on a brand that works well on cats as our "control" group. To be fair to NOW, the fact that their lysine does not work well in cats, does not necessarily mean that it will not work well in humans -but for me, it is a semi-scientific observational indication to stay on a brand that works well in our "control" group

I use this product to protect my cat family from sinus infections and it works very well. The product is well priced and promptly shipped. Thank you

I take two in the morning and have been able to keep away the sicknesses that everyone else seems to be getting.

Got it because it's supposed to be good for you . No adverse effects.

I use this to ward off cold sores around my lips.. Works great.
