What is Lysine? An Essential Amino Acid

Lysine, also referred to as l-lysine, is classified as an amino acid. It is also known as L-2, 6-diaminohexanoic acid, Lisina, Lys, Lysine Hydrochloride, Lysine Monohydrochloride, and other names. 

Lysine is one of the nine essential amino acids in the human body, which act as the building blocks of protein. Lysine is necessary to healthy growth and plays an essential role in the production of carnitine, which is critical to a number of processes in the human body, including healthy heart and brain function. Since the body cannot synthesize lysine, adequate levels of the amino acid must be obtained from dietary sources and supplementation. 

 

What is L-Lysine Used For?

Lysine may be used to improve athletic performance, reduce symptoms of diabetes, prevent the growth and spread of the herpes virus, and more.

Lysine is taken orally, topically, or intravenously. According to Wikipedia, there has been a long discussion that lysine, when administered intravenously or orally, can significantly increase the release of growth hormones. This has led to athletes using lysine as a means of promoting muscle growth while training.

L-lysine also helps the body to absorb calcium. Because of this, it is also used in the treatment of osteoporosis.

 

What Are Some Common Sources of Lysine?

Our body’s main source of lysine is a well-balanced diet. Good dietary sources of lysine are high-protein foods such as eggs, meat (specifically red meat, lamb, pork, and poultry), soy, beans and peas, cheese (particularly Parmesan), and certain fish (such as cod and sardines). Lysine is often sold as an herbal supplement. Since the medicinal use of this product has not been approved by the FDA, l-lysine should never be used in place of medications prescribed by your doctor.

 

Indications

Lysine is used in the treatment of cold sores due to the herpes simplex virus. Some research has indicated that l-lysine may be effective for the treatment of osteoporosis, diabetes, stress, and for athletic performance improvement.

 

Side Effects

Potential side effects of l-lysine supplementation may include:

  • – Diarrhea
  • – Abdominal pain
  • – Chronic kidney (renal) failure
  • – Interstitial nephritis (inflammation in the kidney)
  • – Increased calcium absorption

 

Dosage

According to Drugs.com, the average person with a weight of around 150lbs requires 800 to 3,000mg of lysine daily. Lysine may be dosed as a supplement from 1 to 3 g daily to prevent or treat herpes simplex infections, reserving the higher dosages for breakouts. In addition to the amount of lysine found in the average American diet, l-lysine given at doses in this range appears to be safe for use in adults and prepubescent children. It is important to follow the dosage instructions given by your physician.

 

Contraindications

L-lysine is contraindicated in patients with renal (kidney) or hepatic (liver) disease. It should also be avoided by those already with too much lysine in the blood or urine. As lysine is still a drug under active study, those who are pregnant or breastfeeding should also avoid taking supplemental lysine until there is further research done regarding its safety for infants and children. Do not start or stop taking lysine without talking to a physician.

 

Interactions

Calcium supplements should not be taken along with lysine due to the increased absorption and reduced elimination of calcium.
