Many of the health benefits associated with green tea
are thought to be due, in part, to natural antioxidant compounds in green tea called catechins, the most notable of these being EGCG.
ConsumerLab.com tests found amounts of EGCG in bottled green teas
to vary widely — with some providing as much EGCG as brewable teas, and others providing almost none!
In general, bottled green teas are a costly way to get EGCG, and some contain so little EGCG that you would have to drink an unrealistic amount
in order to get the amount of EGCG found in brewable teas or supplements (which are, by far, the most cost effective way to get EGCG).
If you enjoy bottled tea, see our test results
to see which contains the most EGCG — as well the amounts of caffeine we found in each, the sweeteners and calories they contain, and cost comparisons.
For more about the best way to get EGCG and how the various forms of green tea compare, see the What to Consider When Buying section of the Green Tea Review >>
