Better than Caffeine for me.
I've been taking this on a daily basis for two weeks now, and I do have to say I have felt more focused and energized- something I usually have had to reach to caffeine in order to achieve. At the point which this is a mineral supplement, if taken as is (mixed with just water) the taste can be somewhat off-putting, so I would recommend mixing it with a shake, juice, or even just milk- the daily dose is a tiny scoop full, so the taste really disappears into whatever you mix it with.
