“No matter the individual, all had increased taurine levels after exercise, which suggests that some of the health benefits of exercise may come from an increase in taurine,” said Yadav.
This study revealed a significant increase in taurine among all groups of athletes (sprinters, endurance runners, and natural bodybuilders) and sedentary individuals. The researchers also examined if taurine levels would respond to exercise by measuring levels before and after a variety of male athletes and sedentary individuals finished a strenuous cycling workout. “These are associations, which do not establish causation,” said Yadav, “but the results are consistent with the possibility that taurine deficiency contributes to human aging.” This data revealed that, in general, people with higher taurine levels were healthier, with lower incidence of type 2 diabetes, obesity, hypertension, and levels of inflammation. In the first study, the researchers explored the relationship between taurine levels and approximately 50 health parameters in 12,000 European adults aged 60 and over. This remains unanswered, but the researchers did conduct two experiments to support taurine’s potential in humans. The big question now is whether such benefits would extend to humans. In those experiments, six months of taurine supplements was associated with less weight gain, lower fasting blood glucose and markers of liver damage, increased bone density in the spine and legs, and improved the health of their immune systems.Ĭommenting on the potential mechanism(s) of action, the researchers noted that the compound was found to decrease the number of “zombie cells” (old cells that should die but instead linger and release harmful substances), increased survival after telomerase deficiency, increased the number of stem cells present in some tissues (which can help tissues heal after injury), improved the performance of mitochondria, reduced DNA damage, and improved the cells‘ ability to sense nutrients. These findings were repeated in subsequent studies with monkeys. This would translate to about seven to eight years for humans. This revealed that the lifespan of taurine-fed animals increased by 12% in females and 10% in males.
#TAURINE DOSAGE FOR PEOPLE TRIAL#
Yadav and his co-workers then performed a large trial with middle-aged lab mice (about 45 years old in people terms) and fed them either taurine or a control solution for the rest of their lives. For example, taurine levels in 60-year-old humans were only about one-third of those found in 5-year-olds. “We realized that if taurine is regulating all these processes that decline with age, maybe taurine levels in the bloodstream affect overall health and lifespan,” said Yadav.Īnalysis of blood samples taken from mice, monkeys, and people revealed that taurine abundance decreases substantially with age. Scientists have already reported that taurine plays a role in building bone, and taurine levels are correlated with immune function, obesity, and nervous system functions. We can also produce it enzymatically in our bodies from cysteine. Taurine is an amino sulfonic acid that occurs naturally in meat and fish. The study has garnered a lot of attention in the mainstream media, with headlines such as:Ĭommon energy drink ingredient taurine ‘may slow ageing process’ ( The Guardian) Is taurine the ‘elixir of life’? Maybe, if you’re a worm, mouse or monkey ( CNN) Can Taurine, Found in Energy Drinks, Slow Down Aging? ( The New York Times) and Can Taurine Slow Aging? Here's What the Latest Science Says ( Time). “Not only did we find that the animals lived longer, we also found that they’re living healthier lives,” said Yadav. In female mice, taurine supplementation suppressed age-associated weight gain in female mice (even in “menopausal” mice), increased energy expenditure, increased bone mass, improved muscle endurance and strength, reduced depression-like and anxious behaviors, reduced insulin resistance, and promoted a younger-looking immune system, among other benefits. Led by Vijay Yadav from Columbia University in New York, the researchers also conducted a trial that found that older mice (the equivalent of 60 in human years) receiving taurine supplementation for one year were healthier in almost every way compared to their unsupplemented counterparts.
