L-lysine 500mg - 100 capsules

L-lysine: an important building block of the organism

This dietary supplement from Fairvital provides the high-dose amino acid L-lysine. One capsule provides you with 500mg L-lysine or 1000mg L-lysine with a daily dose of two capsules.

Lysine is an essential and proteinogenic amino acid and cannot be produced by the body itself. It must therefore be ingested with food if possible, but it can also be very well supplemented with dietary supplements if there is an increased need.

L-lysine was first isolated from casein in 1889 by the biochemist Edmund Drechsel. However, his student Max Siegfried published the composition of the amino acid two years later. The Nobel Prize winner, chemist and professor of organic chemistry Emil Fischer presented the final chemical structural formula together with his assistant Fritz Weigert in 1902.

Lysine as a building block of collagen

Lysine is primarily known as a building block of collagen, which is an essential structural protein in the body. Collagen is in turn a component of skin, bones and connective tissue. Collagen can also be found in cartilage, tendons, ligaments and cell membranes.

Other functions of lysine

The primary function of the proteinogenic amino acid is the formation of diverse proteins. In addition to collagen, it is also required for the build-up of enzymes and hormones and is a component of plasma proteins. Important proteins in the blood are, for example, hemoglobin (transports oxygen), transferrin (transports iron), lipoproteins (transports fats) and a protein that binds to retinol and thus transports vitamin A.
Furthermore, L-lysine is part of the so-called Coagulation factors, which are responsible for normal blood clotting. The immune system's immunoglobulins, also known as antibodies, are also dependent on an adequate supply of L-lysine.

Lysine in food

As a protein component, lysine is found in particularly high amounts in protein-rich foods. High levels of protein are primarily found in foods of animal origin. Good sources of lysine are therefore dairy products such as cottage cheese and cheese, as well as eggs, pork and products made from it, beef, and fish. strong> such as sardines, tuna and carp.

Plant sources of L-lysine include soybeans and other legumes such as beans, chickpeas and lentils, peanuts, grains such as rye, bran and oatmeal and baker's yeast.
