Great idea! Have previously taken it in the UK before coming to Madagascar. Have some left in the back of my cupboard here but a little out of date. What dosage would you recommend?

Depends on the strength. People have drank several glasses of 12ppm per day which is over kill but it never turned n=them blue. ;-)

I would recommend just allowing the cs to be in your mouth and swoosh it so it gets absorbed under the tongue and enters the blood stream. If you do ingest it then you need to back it up after with probiotics. Use as much as necessary for as long as necessary.
