USA Onhand | Now L-Lysine ( Healthy Immune Function & Supports Collagen Synthesis )

L-lysine is an essential amino acid, meaning that it cannot be synthesized by the body and must be obtained through dietary sources or supplements. NOW L-Lysine is a dietary supplement that provides this amino acid in a convenient form. Here are some potential benefits associated with L-lysine:

Protein Synthesis:

L-lysine is an essential building block for protein synthesis. It is a crucial component in the formation of various proteins in the body, contributing to the growth, repair, and maintenance of tissues.

Collagen Formation:

L-lysine is involved in the synthesis of collagen, a structural protein that plays a key role in the health of connective tissues, skin, and bones. Collagen is important for maintaining the integrity and elasticity of skin.

Immune System Support:

L-lysine may play a role in supporting the immune system. Some research suggests that it can help inhibit the replication of certain viruses, particularly the herpes simplex virus (HSV). For this reason, L-lysine supplements are sometimes used to manage cold sores.

Calcium Absorption:

L-lysine may enhance the absorption of calcium in the intestines. This interaction between L-lysine and calcium is relevant for bone health and may be beneficial in supporting bone density.

Carnitine Synthesis:

L-lysine is a precursor for the synthesis of carnitine, a compound that plays a role in the transport of fatty acids into the mitochondria, where they can be used for energy production.

Nitric Oxide Production:

L-lysine is involved in the production of nitric oxide, a molecule that helps dilate blood vessels and improve blood flow. This may have implications for cardiovascular health.

Stress Management:

Some research suggests that L-lysine may have a role in managing stress and anxiety. It is believed to interact with serotonin receptors in the brain, influencing mood regulation.

Cold Sore Management:

L-lysine supplements are often used by individuals prone to recurrent cold sores caused by the herpes simplex virus. Some studies suggest that supplementation may reduce the frequency and severity of outbreaks.

It's important to note that individual responses to L-lysine supplements can vary, and the benefits may be influenced by factors such as overall health, diet, and specific health conditions. As with any supplement, it's advisable to consult with a healthcare professional before starting L-lysine supplementation, especially if you have underlying health conditions or are taking medications. They can provide guidance on the appropriate dosage and assess whether L-lysine is suitable for your individual needs.
