Getting the Most from Shapeshifter Teas

Q Concerning your ShapeShifter Teas Booster Caps, the label suggests that one capsule of the Booster Caps should be added into a French tea press along with a serving of ShapeShifter Teas before adding boiling water. Then the brewing Teas should be allowed to steep for at least half an hour before drinking it. To be honest, that is not easy to drink (even after a few minutes). Is my body able to absorb the ingredients of the Booster Caps if I swallow the whole capsule, rather than adding one to the boiling water while making the tea? Does it have the same positive effects on my health?

A Gallocatechin gallate (GCG) is the ester of gallocatechin and gallic acid and a type of catechin. It is an epimer of epigallocatechin gallate (EGCG). In a high temperature environment, an epimerization change is likely to occur, because heating results in the conversion from EGCG to GCG.1 According to the referenced study, the resulting CGC results in even lower dietary cholesterol absorption than occurs with EGCG. While this may be a beneficial outcome with respect to cholesterol reduction activity, for those wishing to maximize the EGCG content of green tea infusions, it is still appropriate to use high temperatures, as long as it is taken into account that extreme conditions will lead to small reductions in total EGCG. For example, total EGCG is reduced by 12.4% when heated for 30 minutes at 100 degrees Celsius.2

To optimize on lowering cholesterol absorption, ShapeShifter Teas Booster Caps are intended to be added to ShapeShifter Teas, which produce an earthy, bitter taste. When the Booster Caps are added, the flavor becomes even more intense. However, by adding lemon or orange oil, the teas become somewhat more drinkable.

Final note: Of individuals who have been consuming ShapeShifter Teas plus the Booster Caps for several months to several years, many report that they have grown to enjoy the flavors.
