General Information

Lysine

Lysine is classified as an amino acid which is a building block of protein. 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. Since the body cannot synthesize lysine, it must be obtained through diet and supplementation. Good 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 medicinal use of this product has not been approved by the FDA, lysine should never be used in place of medications prescribed by your doctor.

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. Lysine also helps in the absorption of calcium. Because of this, it is also used in the treatment of osteoporosis.

 

Indications

Lysine is used in the treatment of cold sores due to herpes simplex. Some research shows it may be effective for osteoporosis, diabetes, stress, and for athletic performance improvement.

 

Side Effects

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

 

Dosage

According to Drugs.com, the average person (around 150lbs) requires 800 to 3,000mg of lysine daily. Lysine may be dosed from 1 to 3 g daily to prevent or treat herpes simplex infections, reserving the higher dosages for breakouts. In addition to the amount 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

Lysine is contraindicated in patients with renal (kidney) or hepatic (liver) disease. It should also be avoided by those with too much lysine in the blood or urine. Because lysine does not have enough research shown, those who are pregnant or breastfeeding should also avoid taking supplemental lysine.

 

Interactions

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