Taurine deficiency as a driver of aging

Researchers measured taurine, a substance made by the body and found in some foods, in about 12,000 people of different ages. Taurine levels generally fell as people got older, but this does not prove taurine caused aging. The researchers then gave taurine to mice, worms, and monkeys, and some measures of health and lifespan improved. Mice given taurine lived about 10% to 12% longer and showed better strength, endurance, bone health, and blood-sugar control. The human part was observational, meaning researchers watched existing patterns rather than testing taurine supplements in people.

What this means for you: This does not show that taurine supplements help people live longer. Do not buy taurine for anti-aging purposes based on this study alone, because human supplement trials are still needed.
