In addition, the taurine-fed mice displayed less depression and anxiety-like behaviors and had immune systems that appeared younger than their biological age. The rodents also had better muscle strength and endurance, expended more energy, and showed increased bone mass. In addition, the mice supplemented with taurine for one year were healthier in virtually every aspect compared to the control mice.įor example, in female mice, taurine curbed age-related weight gain - even in rodents that had gone through menopause. That equates to about seven or eight human years. Then the scientists fed middle-aged mice taurine supplements or a placebo and found that mice fed taurine had a 10% to 12% increase in average lifespan. For example, levels of taurine found in people aged 60 were about one-third found in five-year-old children. To investigate, the team examined taurine levels in mice, monkeys, and humans and discovered that these levels decrease significantly with age. Previous investigations found links between taurine levels and obesity, immune system function, and nervous system function, all of which are impacted by aging.īecause of these earlier findings, the researchers wondered if taurine plays a role in the regulation of aging and whether levels of the amino acid affect the aging process. Uncovering taurine's anti-aging potential What's more, taurine supplementation slowed the aging process in mice, worms, and monkeys, extending the lifespan of mice by as much as 12%, which is equivalent to seven to eight years in humans. In a new study published on June 8 in Science, a team of Columbia University scientists, in collaboration with aging researchers, found evidence that taurine - an amino acid made by the body and present in some foods - appears to be a driver in the aging process. In a series of animal experiments, researchers found that taurine supplements appeared to improve several hallmarks of aging and increase the lifespan of mice.
