Science, made clear

An immune focus. A clear explanation.

  1. The gut–immune connection.

    The gut microbiome interacts with the immune system. This connection is one reason microbiome research matters to our focus on immune health.

  2. Know the strain.

    Strain codes such as BGN4 identify the specific microorganism in a formula and help connect it to relevant research.

  3. Understand prebiotics.

    Prebiotic ingredients provide food for certain microorganisms in the gut. Probiotic products contain the live microorganisms themselves.
