L-lysine is an essential amino acid important for many biological functions, such as immunity, energy production, and muscle growth. Since it is naturally abundant in protein-rich foods like meat, eggs, beans, and vegetables, those most likely to suffer from deficiency are vegetarians and vegans who have a diet low in vegetables and high in grain-based foods.

One of the most common uses of L-lysine supplementation is for the prevention of cold sores caused by the herpes simplex virus. It serves this role in three ways: by preventing viral infection, reducing the risk of cold sore development in people with the virus, and speeding up recovery after the onset of these cold sores. Lysine inhibits the replication of the herpes virus that causes visible warts and pain, itching, and lesions around the lips. It prevents the absorption of the amino acid arginine, which is necessary for herpes virus replication. Without arginine, the virus cannot be fully functional; allowing the body to heal faster and reducing the risk of recurrence.

Lysine is also useful for bodybuilding and muscle mass development and helps maintain carnitine levels, an important factor for energy production and aging. Lysine promotes bone health by ensuring proper calcium absorption and helping to form collagen, which makes up bone cartilage and connective tissues. Finally, lysine supplementation has been shown to reduce mood imbalances and even cortisol levels in people who consume low amounts of lysine.
