What is L-Lysine?

Lysine, or L-lysine, is an essential amino acid. That means it is necessary for human health but the body can't manufacture it. Lysine must be obtained from diet. Amino acids like lysine are the building blocks of protein. Lysine is important for proper growth, and it plays an essential role in the production of carnitine, a nutrient responsible for converting fatty acids into energy. Lysine appears to help the body absorb calcium, and it plays an important role in the formation of collagen, a substance important for bones and connective tissues including skin, tendon, and cartilage. Lysine appears to help the body absorb and conserve calcium. Lysine has many functions in the body because it is incorporated into many proteins, which are used by the body for a variety of purposes.

Lysine may also help break up viruses in the body and is widely thought to improve cold sores.

The Hydrochloride form of lysine is a more absorbable form and is generally what is used when people take a lysine supplement.

Recommended dose:
The recommend dose is 1 of a teaspoon (2500mg) one to three times per day or as directed by a medical professional.  Warning; this supplement is very bad tasting.

Any Side Effects?

Taking too much L-lysine could increase your cholesterol levels and cause gallstones. If you have high cholesterol, gallstones or kidney or liver disease, you shouldn't take L-lysine unless your physician says doing so is safe. High L-lysine intake can also cause diarrhea and stomach cramps.

If you have liver or kidney disease, you should not take amino acids without asking your doctor. It is crucial that you always speak to a knowledgeable healthcare provider before taking any dietary supplements. This advice is also recommended for anyone suffering from a health condition.

Pregnant and nursing women should only take an amino acid after consulting your physician.
