Taurine Supplementation Increases Lifespan and Healthspan in Animals

The level of taurine in our bodies declines with age, dropping by nearly 80%. Would consuming extra improve lifespan or healthspan?

The taurine bump with exercise is interesting, and same with the correlations between lower levels and disease, but what was really notable is the extension of mammalian lifespan from what would seem to be a relatively benign compound started in middle-age. Now with spermidine mice can live like 25% longer, compared to 10 to 12% with the taurine, but presumably through different mechanisms so maybe they’d have additive effects. Then there’s the boost in multiple health parameters in primates. What about the primate that matters most to most people—people. Let’s see what the medical literature has to say in the next video
