    Id rather swallow 2 500mg tablets like these than a larger 1000mg one. Theyre coated making them smoother.

    Starting taking and I’m already feeling a lift in my mood and energy, maybe just the placebo effect but still solid.

    I buy a large quanity of these to take if I begin to feel a cold sore coming on. I take a few high mg. tablets to stop the feel of it beginning. Which is a tender area with maybe a little raised lump. I take a few throughout the next few days to reverse it and make it go away. Catch it quick and keep on hand. BAM!

    I didnt notice tablets (didnt even know it came in tablet form) so will not work for sprinkling on cat food. I will take it myself and get capsules for my cat. As for the L-Lysine, all my cats have loved it on their food. A vet recommended it years ago for respiratory and immune system support for my one purebred who came to me with an incurable respiratory condition which the vet expected would kill him (my cat, not the vet). He lived to be 14 - the oldest lived cat Ive ever had (except for his litter-mate brother who is still alive and in good health). Its impossible to know if the L-Lysine was directly responsible for his long life but it certainly didnt hurt.

    I have been taking L-Lysine for almost 2 years and I have gone from having the most horrible cold sores above my lip (several times a year, that last for weeks no matter what I put on it.) to not having any, well I did have one, but it was very small and was gone within 3 days. I read about this and gave it a try and SOOOOOOOO glad I did. Hope you have the same miracle Ive had.

L-Lysine is an essential amino acid, which means that it cannot be manufactured by the body and must be obtained through the diet or by supplementation. Lysine is necessary for the production of all protein in the body including hormones, enzymes, and antibodies, as well as carnitine and collagen, which is the structural protein forming all connective tissue such as skin, tendon, and bone. L-Lysine also plays a major role in calcium absorption. Some evidence suggests that L-Lysine supplementation may help to support a healthy immune system as well as proper cardiovascular function.*
