More Information

Lamberts L-Lysine 500mg 120 Tablets provide a grade of lysine called USP which is the quality used in clinical nutrition products (cheap lysine supplements may contain animal feed-grade lysine). Lysine is an essential amino acid because it is one of the eight amino acids that our bodies cannot make.

Lysine is used by the body in various ways and, particularly in the formation of collagen, the most abundant protein in the body. Practitioners often recommend lysine during an attack of cold sores since it appears to inhibit the replication of the Herpes Simplex (Type I) virus.

  • 120 tablets.
  • Contains grade USP lysine.
  • Aids the formation of collagen.
  • Recommended for cold sores.
  • Functions as a building block for proteins.
  • Increases the bioavailability of iron.
  • Suitable for vegetarians.

The body requires 2-3g of lysine a day and it is most abundant in high-protein foods such as meat (specifically red meat, lamb, pork, and poultry), eggs, peas, soy and beans, Parmesan cheese, and certain fish (like sardines and cod). Vegetables and vegetable proteins contain low levels of lysine, and so some experts believe that vegetarian and vegan diets may provide an insufficient intake of lysine. 


More Information

Lysine has a known anxiolytic action through its effects on serotonin receptors in the intestinal tract. Studies on rats showed that overstimulation of the 5-HT4 receptors in the gut were associated with anxiety-induced intestinal pathology. Lysine opposed the levels of serotonin and reduced signs of anxiety and anxiety-induced diarrhoea.

Another study showed that a deficiency in lysine lead to a pathological increase in serotonin in the amygdala, a brain structure that is involved in emotional regulation and the stress response. Human studies have also shown correlations between reduced lysine intake and anxiety. A population-based study in Syria included 93 families whose diet is primarily grain-based and therefore likely to be deficient in lysine.

Some studies have found that lysine may be beneficial for those with herpes simplex infections. One small randomized, controlled study found that it reduced outbreaks by 2.4 per year.
