How it works

  1. Stimulates T-lymphocyte maturation and differentiation

    It helps immune T-cells grow up and specialize so they're ready to fight infection.

  2. Enhances natural killer cell cytotoxicity

    It boosts the killing power of natural killer cells, a type of immune cell that targets virus-infected and cancerous cells.

  3. Increases IL-2 and interferon production

    It raises levels of two immune signaling molecules that help coordinate the body's defense response.

  4. Upregulates MHC class I expression

    It increases a molecule on the surface of cells that helps the immune system recognize infected or abnormal cells.

  5. Promotes dendritic cell maturation

    It helps mature the immune system's 'messenger' cells, which are responsible for alerting T-cells to threats.

Result

A stronger, better-coordinated immune response against viral infections and abnormal cells. In practice, this may mean recovering from infections more quickly or getting sick less often, particularly for those with a weakened immune system.
