We spend a lot of time chasing exotic molecules, but sometimes the most compelling longevity interventions are hiding in plain sight. In 2023, a landmark paper in Science upended how we view taurine, an amino acid best known as a cheap additive in energy drinks. The researchers demonstrated that blood levels of taurine decline by over eighty percent across our lifespan. When they supplemented older mice, monkeys, and worms with taurine, they saw a ten to twelve percent increase in median lifespan in mice, accompanied by improvements in bone density, muscle mass, and mitochondrial function (see [1]). In the hierarchy of evidence, this is robust animal data paired with strong mechanistic plausibility, specifically showing that taurine suppresses several fundamental cellular hallmarks of aging (see [2]).
