L-lysine is a dietary supplement formulated to promote immune health, support protein synthesis, and support antioxidant activity. L-Lysine is available in capsules from Natura-Genics®.

How It Works

L-lysine is an essential amino acid, which means the body does not naturally produce it. Instead, it must be obtained through diet or lysine supplements. It is a crucial building block for protein synthesis and plays an important role in immune function.

Benefits of L-lysine

  • Supports immune function
  • Promotes canker and cold sore relief and prevention
  • Supports protein synthesis
  • Promotes antioxidant activity

Promotes Immune Health

Healthy levels of lysine in the body may promote protection against viruses, bacteria, and other pathogens. L-lysine is believed to help the body produce infection-fighting antibodies, enzymes, hormones, and body tissues.

Promotes Canker and Cold Sore Relief and Prevention

Some studies have suggested that L-lysine may be effective in relieving cold sores by stopping the reproduction of the virus that causes them-herpes simplex virus (HSV). L-lysine also appears to compete against arginine, an amino acid that is necessary for HSV replication, promoting balance between the two and supporting the inhibition of viral replication. L-lysine supplementation may promote similar effects on canker sores, promoting reduced frequency, severity, and duration.

Supports Protein Synthesis

Amino acids are the building blocks for proteins. Cells are continuously making proteins through the process of protein synthesis. To make a new protein, ribosomes match genetic coding with a specific amino acid such as l-lysine. Amino acids make up proteins that help the body break down food, grow, and repair body tissue, among many other bodily functions.

Supports Antioxidant Activity

Antioxidants help protect the body against oxidative stress caused by free radicals. A balance between free radicals and antioxidants is crucial for overall well-being. Alkaline amino acids, including l-lysine, have been reported to have strong antioxidant activity.
