L-Lysine HCL Background and Benefits

Lysine is an essential amino acid, meaning that it is not able be synthesized in the body. It has the chemical formula HO2CCH(NH2)(CH2)4NH2, and its codons are AAA and AAG. L-lysine is the biologically active form of lysine in animals.

L-lysine is the precursor for many substances that are important in human nutrition. Alpha ketoglutarate is used to convert L-lysine into acetyl-CoA, which plays an essential role in the citric acid cycle. Allysine is also derived from lysine and is used to synthesize collagen and elastin.

L-lysine can be synthesized in the laboratory from dl-α-amino-ε-caprolactam and an enzyme. The commercial production of L-lysine typically relies on fermentation by the bacteria known scientifically as Corynebacterium glutamicum. L-lysine for use in health supplements is typically prepared as L-lysine HCL, which is the hydrochloride salt of L-lysine.

Uses of L-Lysine HCL

The most common use of L-lysine HCL in dietary supplementation is to aid with the natural recovery of sores.

L-lysine may help to manage stress in women. They may also help manage anxiety in males.

Blood sugar management

Some studies show that daily doses of L-lysine for two months can help support the body’s ability to maintain a healthy blood sugar level.

Cold sore management

Studies show that oral supplements of L-lysine may help the body manage cold sores caused by the herpes simplex labialis virus. Topical creams containing L-lysine may also be used for this purpose.

Canker sore management

Early research indicates that L-lysine may help the body manage canker sores. The dosages studied for this purpose were as high as four grams of L-lysine per day.

Signs You May Need L-Lysine HCL

Humans normally get adequate amounts of L-lysine from dietary sources, except in specific circumstances. L-lysine is primarily found in animal protein, so strict vegetarians may need L-lysine supplements. This is especially likely when a vegetarian doesn’t eat beans. Other groups that often develop an L-lysine deficiency include athletes and burn patients. As an essential amino acid, an inadequate intake of L-lysine may cause many signs such as loss of appetite, fatigue and slow growth.
