Observational analysis shows no link between taurine levels and physical performance in aging adults, suggesting deficiency may not drive aging.
Taurine deficiency was recently proposed as a driver of aging in various species, including humans. To test this hypothesis, we assessed whether circulating taurine was associated with aging and physical performance in 137 physically inactive and physically active men aged 20–93. No association between circulating taurine levels and age, muscle mass, strength, physical performance, or mitochondrial function was observed, thereby challenging the implication of taurine deficiency as a primary driver of aging in humans.
