Klotho

Klotho is a protein tied to longevity, kidney function, and cognitive resilience, and its levels fall as you age. Klotho tests are the only way to know where yours stand, because no standard blood panel includes it. Our Klotho test runs through a CLIA-certified laboratory and comes back with interpretation rather than a bare number you have to decode yourself. Knowing your level gives you a baseline you can act on and retest against later. Klotho is also included in the AgingSOS Advanced and Ultimate panels if you want it alongside NAD, senescence markers, and inflammatory cytokines for a fuller picture of biological aging.
