№ 696. Taurine & Aging

 

Taurine deficiency as a driver of aging.

Taurine concentration in blood declines with aging (top left). A reversal of this drop through taurine supplementation increased healthy life span in mice and worms but not in yeast (bottom left and top middle). Taurine supplementation affected several hallmarks of aging (middle). In humans, lower taurine concentrations were associated with multiple diseases (top right). A randomized controlled clinical trial in humans is warranted to assess the antiaging effects of taurine (bottom right). BMI, body mass index.

A deficiency of taurine—a nutrient produced in the body and found in many foods—is a driver of aging in animals, according to a new study led by Columbia researchers and involving dozens of aging researchers around the world.

The same study also found that taurine supplements can slow down the aging process in worms, mice, and monkeys and can even extend the healthy lifespans of middle-aged mice by up to 12%.

The study was published June 8 in Science.

“For the last 25 years, scientists have been trying to find factors that not only let us live longer, but also increase healthspan, the time we remain healthy in our old age,” says the study’s leader, Vijay Yadav, PhD, assistant professor of genetics & development at Columbia University Vagelos College of Physicians and Surgeons.

“This study suggests that taurine COULD be an elixir of life within us that helps us live longer and healthier lives.”
