Sort of! The theory is that smaller water clusters slip into your cells faster. That might mean a little extra oomph for your hydration after a sweaty workout. But honestly, your regular H₂O does a stellar job already.
One study suggested alkaline water with a pH of 10 could help with blood viscosity—basically, making your blood flow like a smooth jazz saxophone instead of sludge. But the effect was tiny, and we’re not talking life-changing. Drink up, but don’t expect to turn into the Flash.
And here’s a joke: why did the alkaline water break up with the tap water? Because it needed more “cation” time. (Get it? Cations? I’ll see myself out.)
