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

One of the most common uses for supplemental L-lysine is for preventing cold sores caused by the Herpes Simplex virus. It does this in three different ways: by preventing infection with the virus, reducing the risk of developing cold sores in those with the virus and speeding up the recovery after cold sores develop.  Lysine inhibits replication of the herpes virus that causes the visible outbreaks and pain, itching and sores around the lips. It interferes with the absorption of the amino acid arginine, which the herpes virus uses to replicate. Without arginine, the virus cannot be fully functional which allows the body to heal quicker and reduce the possibility of recurrence.

Lysine also supports bodybuilding and muscle growth and helps maintain carnitine levels, an important factor in energy and aging. Lysine supports bone health by ensuring the proper absorption of calcium and helping to form collagen that makes up bone cartilage and connective tissues. Finally, supplementation with lysine has been shown to reduce mood imbalances and even cortisol levels in those who consume low amounts of lysine.

Anxiety

L-lysine has been proven to reduce levels of chronic anxiety in those who have low dietary intakes of the amino acid. A double-blind, placebo controlled and randomized study including one hundred and eighty healthy Japanese adults were given a week-long oral treatment with L-lysine (2.64 g per day) and L-arginine (2.64 g per day) to access whether or not the treatment could normal hormonal stress responses in persons with high trait anxiety. In was confirmed that in both sexes, the treatment with these amino acids caused a significant reduction in both trait and state anxiety as well as decreasing the basal levels of salivary cortisol and chromogranin-A (a salivary marker of the sympatho-adrenal system) in male subjects.

Cold Sores

L-Lysine is mainly thought to reduce the recurrence of cold sore or herpes outbreaks, although its effect on severity and duration of symptoms is debatable. One 6-month study found that recurrence, severity and duration were all significantly reduced with a minimal dose of 1,248mg of lysine per day. However, in shorter studies, such as 12 weeks long, severity and duration have not always been significantly decreased. L-lysine is found to be especially effective when combined with a prescription antiviral medication such as acyclovir (Zovirax™) or valcyclovir (Valtrex™).

Safety and Side-Effects

Generally, L-Lysine is incredibly safe. Conventional dosages of L-Lysine supplementation (3-6 grams daily) haven’t been reported to cause any problems in humans. Many of the treatment dosages for herpes and cold sores are as low as approximately one gram a day in three divided doses. Problems do not seem to appear until intakes reach very high levels (15-40 grams daily) and even these dosages produce only isolated reports of abdominal cramps and transient diarrhea. Doses of that quantity have also been associated with the possibility of increasing the toxicity of aminoglycoside antibiotics such as gentamicin, neomycin and streptomycin.
