Taurine is included in energy drinks primarily because it is an amino acid that supports cellular energy production and has calming effects on the nervous system. It helps balance fluids and electrolytes and is known to suppress certain neurotransmitter receptors, which can help offset the jittery effects of caffeine in these drinks. Additionally, taurine may support cardiovascular and muscular health, contributing to improved physical and mental performance. While taurine itself is not a stimulant, it is believed to help reduce the anxiousness caused by caffeine, creating a more balanced energy boost in the drink.
