the toxic form of caffiene.

As I have stated before,
non of the caffiene in green tea affects us in a toxic way.
It is a different means of the property utilised by the plant.

Simiarly note that stevia is a sweetener,

so mine tends to last much longer and even tho taking a reduced dose,
I still get benefits overall.
