Anyone researched or making/drinking ionized water -- popularized by Kurzweil as an anti-aging elixir?

I’ve been reading a bit online and looking at different devices for making ionized water. Wondering if anyone’s dug deeper into the science and has opinions on merits. I know there are a lot of sites that say claims that it’s good for you are pseudoscience, but Kurzweil’s no idiot, so I’d like to understand the optimistic scientific perspective a bit I guess.
