A naturally occurring amino acid, l-lysine is one of the only 20 amino acids that serves as a building block for proteins. L-lysine is a component of all of the proteins in the human body and is crucial for good health. With such an important role in the body, l-lysine is used as an effective treatment option and supplement.
What is L-Lysine?
An essential amino acid, l-lysine or lysine is necessary for human health. However, the body cannot manufacture the nutrient, so it is important to get enough of the nutrient via dietary intake or supplement.
Lysine serves as a building block for proteins in the body, making it important for growth and development. The nutrient also functions in the production of other nutrients including carnitine, which regulate the processing of fatty acids in the body.
While most individuals get an adequate amount of l-lysine in their diets, some individuals including athletes, burn patients and some vegans do not. An insufficient amount of lysine in the diet leads to fatigue, nausea, dizziness, decreased appetite, irritability, bloodshot eyes, delayed development, anemia, and reproductive issues.
Health Benefits of Lysine
As a building block of proteins in the body, lysine is a vital nutrient for supporting proper growth and development; however, the nutrient serves other purposes as well. Research suggests that the nutrient also helps the body absorb calcium. Likewise, it appears to play a part in the formation of collagen, which supports bone and tissue health, including skin, tendon, and cartilage development.
Being such a crucial nutrient, l-lysine can also help manage a variety of health conditions. The nutrient can be used to control cholesterol levels, prevent osteoporosis and other age-related bone density conditions, support growth and reduce anxiety and stress. The nutrient is also effective for preventing herpes, treating shingles, relieving pain due to inflammation and maintaining heart health.
As with any health supplement, care must be taken when using l-lysine as both too much and too little of the nutrient can cause health concerns. In any case, though, lysine is an effective health support that prevents and treats a wide range of conditions.

[SIDE EFFECTS] I have taken L-Lysine for canker sores and it worked great. I havent had one since.
If taken for a while L-Lysine can have an effect on your liver, my mistake was that i kept experimenting and supplementing on it even though i did not need it. It is good but you should pay attention to your arginine levels (consume arginine foods or supplements), as an unsafe drop in those levels can damage your liver. As in my case after consuming about 2-3 grams a day for about 3-4 months resulted in a morning with pain in my liver and a feeling as if i had a cinder block under my ribcage(i had no idea there was such a thing such as liver pain and swelling). Stopped supplementing on it, and 2 days after my liver felt way better. My cholesterol levels were also unusually high during supplementation and they went back to normal after stopping, so people should keep these things in mind, i know its easy to miss these warnings since i missed them myself. The beautiful thing about the liver though is that it can repair itself, but that doesnt mean you shouldnt be careful. Milk Thistle can help repair your liver. And if i had to do this all over again i would take L-Arginine along with L-Lysine. It would be great if someone posted these warnings in the main description for awareness so they can learn from my mistake. Thanks
