Taurine levels fall with age in mice, monkeys, and humans. A landmark 2023 study in Science suggests that this decline is not merely a byproduct of growing older, but potentially a driver of the aging process itself.

Key Findings Across Species

When researchers restored taurine levels in middle-aged animals, they observed significant improvements in health span and cellular function:

• Mice: Supplementation extended median life span by 10–12% and improved function in muscle, bone, brain, and immune systems.
• Monkeys: Taurine enhanced key health markers, supporting better metabolic and inflammatory profiles.
• Worms & Yeast: Life span increased in worms, though no benefit was observed in yeast.
• Cellular Hallmarks: Taurine reduced cellular senescence and DNA damage, improved mitochondrial function, and lowered chronic inflammation.

What This Means for Humans

Human testing was observational: lower taurine levels correlated with age-related diseases, while endurance exercise was found to naturally elevate taurine levels. While these findings position taurine as a promising longevity target, clinical trials are still required to prove whether supplementation is safe and effective for human aging.
