I started a few days ago with Oxypowder (there is also colosal and homozone).
This is suggested on the Andreas Moritz site. This works with oxygen and it turns the solids into water.
Actually he does not like the PB shakes.
According to the company they say you can keep using the Oxypowder for the rest of your life.
It is easy to take it is in capsules. They also have the powder, but then you have to add lemon.
