Actually the alkaline balance is a good indicator but it too is just an indicator. The real story takes place beyond the indicator.
It comes down to toxins and lack of nutrition at all levels (spiritual, mental, emotional, and physical). Coherency or disharmony resonates at all levels. It is based on choices that lead us in either direction.
Go against nature and create disharmony. Go with it..... (you get the idea).
We don't need any "products" to "save" us. We need to get back in the driver's seat and get back to the harmony of who we are and live accordingly.
People can manifest a swamp or a springwell. It comes down to coherent choices.
