Taurine

A landmark 2023 study in Science made waves when it found that taurine levels decline significantly with age — and that supplementing taurine in animal models extended healthy lifespan by up to 12%. While human longevity trials are ongoing, the data is compelling enough that taurine has become one of the most talked-about longevity supplements in the field.

Beyond the longevity buzz, taurine has decades of research supporting its cardiovascular benefits. It helps regulate calcium signaling in the heart, supports healthy blood pressure, and acts as an osmolyte — maintaining proper fluid balance in cells. Your heart contains more taurine than almost any other tissue, and levels correlate strongly with cardiac function.

Taurine also supports exercise performance by improving calcium handling in muscles, buffering oxidative stress during intense effort, and supporting electrolyte balance. Studies show it can improve endurance capacity and reduce exercise-induced oxidative damage. It's the reason energy drinks have always included taurine — though you're better off getting it without the sugar and caffeine.
