L-lysine is an essential amino acid, which means that the body cannot produce it on its own and must therefore obtain it from food. L-lysine performs a variety of functions in the body:

Protein synthesis : L-lysine is a building block for proteins and therefore plays an important role in protein synthesis. Proteins are crucial for building and repairing tissue, building muscle, and many other physiological processes.

Collagen synthesis : L-lysine is also important for the production of collagen, a structural protein that helps strengthen and keep elastic skin, bones, tendons, cartilage and other tissues. Adequate intake of L-lysine is therefore important for skin health and wound healing.

Calcium absorption : L-lysine plays a role in the absorption of calcium from food and its storage in bones and teeth. It may help increase bone density and reduce the risk of osteoporosis and bone fractures.

Immune Function : L-lysine may boost immune system function by supporting antibody production and immune cell activity. It may help strengthen the body's defenses against infection and speed recovery from illness.

Herpes virus prevention : Some studies suggest that L-lysine may inhibit the replication of herpes viruses and reduce the frequency and severity of herpes outbreaks. It is often used as a dietary supplement to prevent and treat cold sores (herpes labialis).

Mood and mental health : L-lysine is a precursor to neurotransmitters such as serotonin, which is important for mood regulation and emotional well-being. Therefore, adequate intake of L-lysine may help stabilize mood and reduce symptoms of depression and anxiety.

Fieberblasen weg

Unglaublich. Die Therapie mit Lysin war nach nur wenigen Tagen erkennbar. Meine Fieberblasen waren, doppelt so schnell, wie gewöhnlich, weg!
