I always love the scientific language they throw at people to get them to buy stuff. Next time you see a commercial that tells you "natural ingredients like carrots"... ask yourself, why does my body need these natural ingredients? Arsenic is natural for fuck sake.
I mean i'm not actually sure what the natural pH levels of the human body are, but when they just throw out there that it's got a pH of 9 and will therefore decrease acidity in your body, is that necessarily a good thing? Natural waters occur at around 6 pH, and as pH is a negative logarithm of the hydronium ion concentration, that's more than just a linear increase of 3 in hydronium ions. this is just retarded. Anyone know more chemistry that could back up there pH claims?
