What is the best electrolyte drink for labor?

Could you please elaborate on the importance of choosing the right electrolyte drink during labor? As a pregnant woman, I'm keen to understand why selecting the best option is crucial, and what specific factors I should consider when making my choice. Is there a particular brand or type of drink that's widely recommended by experts for maintaining optimal hydration and electrolyte balance during childbirth? Additionally, how do the benefits of electrolyte drinks differ from simply drinking water during labor?
