What is Lysine?

Lysine, or L-lysine, is an essential amino acid. This means that it is a building block of protein and essential to our health, but cannot be produced by our body. Therefore, we must obtain lysine from food or supplements. Some dietary sources of lysine include red meat, pork, poultry, cheese, cod, sardines, eggs, soybeans, and spirulina.[1]


What are the benefits of Lysine?

Lysine is an integral part of many biological functions. It supports proper growth and development in children, calcium absorption, and synthesis of connective tissues such as bone, skin, collagen, and elastin. It also plays a crucial role in the production of carnitine, which converts fatty acids into energy and helps to lower cholesterol. Perhaps what it is most well known for, though, is its role in the maintenance of healthy immune function, specifically in regards to antiviral activity.[2]

Lysine is often used in the management of Herpes simplex virus (HSV) infections. While there is still some debate on the efficacy of lysine supplementation as treatment for HSV, several studies have found very promising evidence.[3-5] One such study, a double-blind, placebo-controlled trial, found that L-lysine supplementation 3 times a day for 6 months significantly reduced the symptoms, severity, healing time, and number of infections.[3]

There is also evidence to suggest Lysine supplementation can reduce chronic anxiety in individuals with low dietary intake of the amino acid. A double-blind, placebo controlled and randomized study found that a week long oral treatment with L-lysine and L-arginine, another amino acid, significantly reduced anxiety in healthy individuals.[6]


Why take Lysine supplements?

While incidence of lysine deficiency in developed countries is rare, some individuals, such as vegetarians and athletes, are at risk for deficiency. Signs and symptoms to look for include fatigue, nausea, dizziness, irritability, anemia, slow growth, and reproductive disorders[2]
