Lysine is an essential amino acid, meaning that it is vital to human health but cannot be manufactured by the body. Due to this reason, lysine must be obtained from food or supplements.

In the body, lysine is used to produce acetyl-CoA, a significant molecule used in energy production. Lysine also helps the body absorb and conserve calcium. It plays a crucial role in the formation of collagen, a substance critical for bones and connective tissues including skin, tendon and cartilage. More importantly, lysine helps boost the immune system by aiding the production of antibodies.

    Really good lysine I bought this in the store and the prices are expensive and you only get small containers. Purchasing this from hard rhino is like twice as cheap for like over 5 times as much, I've been stacking it with other amino acids and i feel like it works nicely!

    I happened onto your site late one night trying to find help for my 35 kitties with URI's. I am in rescue and knew L-Lysine was great for cats. I took your product to my vet and she said I had ordered the BEST product for them with you and so I ordered 4 more pounds! Thank you for being out there for my beloved kitties. Would you like to give one a forever home????

    Thanks, Cindy Boykin
