    And those aging-related conditions?
    They’re the precursors to diabetes, heart disease and stroke in humans.

    So what was the difference?

    The Florida pod ate different fish than their California friends. Fish with higher levels of fatty acid C15:0 (aka FA15™).

    When the California pod switched to fish with higher levels of C15:0 (aka FA15™), their aging-related conditions stabilized and their cells stabilized, too.

     
     

    Bottlenose dolphins are a lot like us.

    They live for a long time. They’re social and intelligent. And they can develop aging-related conditions.

    But with our fatty15 breakthrough, we’re just getting started helping both humans and dolphins age in healthier ways.*

      A Foundation for Overall Wellness

      After a few months, I feel a noticeable difference in my overall well-being. It’s hard to pinpoint to just one thing—my energy is steadier, my skin feels more hydrated, and I just feel more resilient. It feels like I’m giving my body a fundamental building block it was missing. This has become a non-negotiable part of my daily health routine.
