Lysine and Stress

An interesting study concludes that foods fortified with Lysine can reduce anxiety and stress in people whose diets are Lysine-deficient. This reflects the importance of the relationship between amino acid nutrition and mental health and more specifically, Lysine and stress.

The amino acid Lysine is a vital building block for all protein in the body. Lysine plays a major role in calcium absorption; building muscle protein; recovering from surgery or sports injuries; and the body’s production of hormones, enzymes, and antibodies.

This important amino acid is found in many foods, and is easily consumed as part of a balanced diet. High protein foods such as such as eggs, meat (specifically red meat, lamb, pork, and poultry), soy, cheese (particularly Parmesan), and certain fish (such as cod and sardines) contain Lysine.

However, Lysine deficiencies can be found in communities consuming wheat as a staple food. Lysine is the limiting amino acid (the essential amino acid found in the smallest quantity in the particular foodstuff) in most cereal grains.

Lysine and stress  — reduction through fortification

As part of a three-month wheat fortification trial, dietary data were collected on five impoverished communities in northwest Syria, who depended mainly on wheat for their dietary supply of protein.

The study, reported by Nevin Scrimshaw, Miro Smriga, Shibani Ghosh, et al, from the Food and Nutrition Program, United Nations University, hypothesized that fortifying a lysine-deficient diet in poor communities would reduce anxiety and stress, and improve the quality of life. In other words, they believed that there was a genuine connection between Lysine and stress.

The study found that people on the lysine fortification diet reported significantly reduced chronic anxiety. Results indicate that not only long-term anxiety but also acute stress response is lessened by lysine fortification.

It is hoped that stress-related problems, which range from high anxiety to infectious diseases, will be solved by offering lysine fortified foods to other impoverished populations with no other source of dietary protein.

Your Liver Benefits from Sulfur-Containing Amino Acids Methionine and Cysteine

The Amino Acid-Sulfur Deficiency Pattern Has Been Found in Human Chronic Liver Disease.

A study about advanced liver disease (chronic liver disease) demonstrates that the metabolism of sulfur-containing amino acids—like methionine and cysteine (but no difference in taurine)—is impaired.  A study by P Almasio, G Bianchi, et al., was done at the Clinica Medica R, Università di Palermo, in Italy. Their findings in 60 people with chronic liver disease from a clinical trial were fascinating.

Cysteine and Methionine Benefits Those Suffering from Chronic Liver Disease

In the study, 10 of the subjects were healthy (used as a control), whereas the other 50 patients had these chronic liver diseases (proven with biopsy):

30 cases of chronic hepatitis
10 cases of compensated cirrhosis
10 cases of decompensated cirrhosis
(hypermethioninemia—an extreme amount of methionine—was present in only these latter cases)

The results of this human clinical trial showed that cysteine, which is a metabolite of methionine metabolism, was “markedly reduced in patients with compensated chronic liver disease, while in advanced cirrhosis its concentration was within the normal range.”

Methionine is an essential amino acid (meaning it must be gotten through dietary proteins like beef, chicken, fish, or eggs since these proteins provide all 22 amino acids). Cysteine is a non-essential amino acid (meaning your body can produce it on its own rather than needing dietary supplementation). The amino acid taurine (in plasma levels), however, were observed between the different groups yet no differences were observed.

What was discovered was the derangement in sulfur-containing amino acid metabolism “possibly located at various steps along the trans-sulphuration pathway, is also present in mild forms of chronic liver disease.”

Methionine Benefits

The bottom line is that chronic liver disease proves out a marked deficiency of sulfur-containing amino acids in the people suffering from it for cirrhosis (except in decompensated cirrhosis), or even hepatitis. This study did not provide information on whether supplementation of methionine or cysteine would positively affect these patients with chronic liver disease; however, that these amino acids are associated with healthy livers, and abnormal in diseased livers, is certainly telling.

Lysine and Shingles: Taking Lysine to Protect Against Shingles

Lysine for Shingles? Lysine is a commonly available amino acid found in most drugstores, but did you know that you can also use Lysine for shingles by helping relieve the agony and pain brought about by the shingles virus? 

The shingles virus is the same virus that causes chicken pox and is called the herpes zoster virus. It causes painful, fluid filled blisters and can be transmitted to people who have never had chicken pox.  Contracting the virus from someone with shingles causes the individual to contract chicken pox rather than shingles.

The elderly and people with compromised immune system are the most likely to come down with shingles. While there is a vaccine available for shingles, it is still experimental and the dose given of shingles in many times the potency of the traditional chicken pox virus that most receives as children.

Lysine Dosage for Shingles

Lysine works to fight shingles as it replaces other factors that encourage the growth of shingles blisters and usurps their role in the body. It is recommended to take a supplement of lysine if you are susceptible to the shingles virus.

If you are between shingles outbreaks, take one gram of lysine per a day. If you are experiencing the blisters characteristic of shingles, then take one gram of lysine three times daily.  We usually get our lysine from foods high in protein as our bodies are incapable of making lysine for themselves.

The chicken pox virus never goes away once you have had it, and fragments of the original virus are still contained in the body.  The fragments use an amino acid called arginine in order to grow but lysine blocks the arginine and therefore, blocks the growth of the shingles virus.

Lysine has been shown in clinical studies to block shingles from causing an outbreak and to heal existing blisters and also to shorten the road to healing once the blisters begin to fade.  Lysine is a master repairing agent in the body and so, taking lysine quickly causes the blisters and rashes caused by shingles to disappear.
