The idea behind taking the Oxypowder once at night is that you don't want to apply the oxygen to food. That will just cause discomfort and you wouldn't get the full impact of the oxygen in your body. It will be used up breaking down the food. This makes sense to me.

I've never heard of Mag 07, but I'd have to wonder about it's potency if you can take it comfortably throughout the day. Also, homozone and coloson are normally not in the stores either. They are less expensive than Oxypowder . They are available on line. As you mentioned, they require mixing with an acidic drink like lemon juice. Oxypowder also has the germanium which is really well tested and very healing.
