The only experiment on humans in the study found exercise - often called the key to longevity - improved taurine levels in people. “Some additional studies in humans using taurine supplements would be interesting, but we are long way from suggesting their use.” “In our cohorts with over 130,000 men and women followed for up to 30 years (with more than 30,000 deaths), greater intake of animal protein was related to higher overall mortality and mortality from most major diseases,” Willett said in an email. Chan School of Public Health and professor of medicine at Harvard Medical School. Walter Willett, a professor of epidemiology and nutrition at Harvard T.H. “This doesn’t seem like a story ready for prime time, and it could be harmful if people started consuming more animal-sourced foods to increase taurine intake,” said leading nutrition researcher Dr. “At the end of the day, the findings should be relevant to humans.”īut worms, mice and monkeys are not people, and science is years away from proving taurine’s anti-aging value in humans - if it even exists, experts warn. “These studies in several species show that taurine abundance declines with age and the reversal of this decline makes the animals live longer and healthier lives,” Yadav said. Tests in monkeys found those who took taurine supplements were leaner, had better blood sugar levels and less liver damage, had increased bone density, a younger-looking immune system and gained less weight, according to the study. Taurine deficiencies are linked to heart, kidney and retinal damage.Ībsorbed from foods such as shellfish and meat and distributed by the liver, taurine levels decline with age, “but if you top it up back to youthful levels, then you have this effect that the mice live healthier for longer,” coauthor Henning Wackerhage, a professor of exercise biology at the Technical University of Munich in Germany, said in the briefing. Studies have found it may be anti-inflammatory and neuroprotective in older brains but potentially harmful to the developing brains of adolescents. Ready for ‘prime time’?Ĭonsidered a non-essential amino acid, taurine exists in the brain, retina and nearly every muscle and organ tissue in the body. “This study suggests that taurine could be an elixir of life within us,” Yadav said in an earlier news release on the study, which published Thursday in the journal Science.
