All About Lysine

The amino acid Lysine is often written as L-lysine. Lysine is categorised as an essential amino acid because it cannot be made by the body so must be consumed.

Amino acids are made up of 3 nucleotides to make a codon. These are specific to the amino acid of which lysine has two, they are AAA (Adenine-adenine-adenine) and AAG (Adenine- Adenine-Guanine).

The best dietary sources of L-lysine are beef, lamb, turkey, chicken pork, dairy products, soy, fish and eggs. Lysine was discovered by scientists Drechsel. He first extracted the amino acids from casein.

Amino Acids Lysine + Methionine = Carnitine

The primary action of Lysine is to produce Carnitine. Our body intelligently combines amino acids lysine and methionine to produce Carnitine. Carnitine is used in the body to promote energy production and mediate fat metabolism.

Here are the health benefits of Lysine :

  • Lysine is also through to promote calcium absorption by reducing the volume of calcium excreted in urine.
  • Lysine has been linked with the herpes simplex virus since the 1950s. Studies showed that consuming foods high in lysine seemed to suppress the symptoms of the virus.
  • Seeing as Lysine is an amino acid, the building block of protein it makes sense that it can promote muscle production and size.
  • One study found that taking a combination of lysine and arginine helped to reduce traits associated with anxiety and high mental stress.

Lysine is recommended to be taken with copper, zinc or iron as this seems to improve Lysine’s absorption. Do be careful to take these 3 minerals separately on occasion, as it seems to reduce their absorption.

Recommended daily allowance of Lysine : 30mg/kg of body weight; this is approximately 2-3g of L-lysine per day.

      Yes Deep. From preventing cold sores to strengthening the skeletal structure of the body. Lysine is an effective amino acid that supplements the body with numerous benefits. Without sufficient levels of lysine, the body is unable to produce the appropriate hormones and immune cells.

    This reminds me on Jurassic Park. The dinos were breed lysine deficient, but I guess we are all by nature.
