12 Jun 2023 --- Researchers have probed the effects of taurine on the health span and life span across several living species. In a new study, they measured the blood concentration of taurine during aging, while seeing how supplementing with this amino acid can help support life quality. Taurine, a semi-essential micronutrient, is one of the most abundant amino acids in humans and other eukaryotes. Earlier studies have shown that the concentration of taurine in blood correlates with health, but a gap in research has been the question of whether this affects aging.
