Thanks Patrick!
A WebMD search for Nullo shows the active ingrediant to be chlorophyll. So when I looked that up on a british suplements speciailst I get a few that show Chlorella (Rich in Chlorophyll).

I can keep going longer if it shows some benefits in this area for me, but most of the other reviews clearly need some "time of the month" support (which i don't need - but the messing deororant will be hopefully a thing).
Thinking fortnight away as just restarted a fibre supplement.
