I am no expert but I will share my stories. Alkalizing machines seperate alkaline minerals from acid minerals in the water, so you are not getting a balance of both, plus the much needed live carbons. That is why eating good high brix foods are so important to our bodies. It has everything you need for your body to get the most from it.
I have one of these machines and find no problems using the water to mix with my ML drinks but it gives me a totally different (negative) reaction if I drink lots of the alkalkine water alone. It gave me those "phoney" detox symptoms, when really it just was not meeting my body's needs.
You may find some other uses for it that are helpful but I don't think I would have spent my money on one now that I know about the ML protocols.
