ʟ-Lysine, an essential amino acid crucial for balanced nutrition and overall well-being, is among the nine amino acids the body requires.

This amino acid is vital for growth and tissue repair, falling into the category of the nine "essential" amino acids due to its non-production within the body. As a building block for proteins, ʟ-Lysine plays a key role in the production of enzymes, hormones, and disease-fighting antibodies.

Rich sources of ʟ-Lysine include red meats, fish, and dairy products like milk, eggs, and cheese. While vegetables generally offer a poor lysine supply, legumes such as beans, peas, and lentils stand out. The daily recommended intake for adults is around 12 mg/kgbw, approximately 800 mg. While dietary sources typically fulfill lysine requirements, supplements are increasingly popular for treating and preventing specific ailments. With a net positive charge at physiological pH values, lysine is considered one of the three basic amino acids in terms of charge. It is commonly found on protein and enzyme surfaces and may appear in the active site. Lysine constitutes 7% of proteins on a molar basis compared to other amino acids.

Researchers are exploring lysine supplementation and consumption of lysine-rich foods for potential benefits such as lowering cholesterol, improving athletic performance, and aiding recovery after surgery. Some suggest lysine during canker sore outbreaks for faster healing, although clinical trials on its efficacy are limited.

A noteworthy application of lysine is its use in managing and preventing herpes sores caused by the herpes simplex virus (HSV). Supplementation with ʟ-Lysine tilts the balance in favor of lysine, disrupting the arginine-dependent replication of the herpes virus.

Additionally, lysine has demonstrated usefulness in preventing atherosclerosis, the hardening of artery walls due to lipid deposits. By potentially loosening and preventing these deposits, lysine contributes to maintaining flexible artery walls, reducing susceptibility to hypertension, a major factor in heart attack and stroke.

Lysine's role in calcium absorption and reduction of its excretion leads some researchers to consider its potential role in preventing and treating osteoporosis. Collaborating with other essential amino acids, lysine supports growth, lean body mass, and the body's nitrogen store.
