Decaffeinated tea is a popular alternative for tea drinkers who don’t want that extra caffeine content. While tea contains far less caffeine than a cup of coffee, it is still present. A moderate amount of caffeine each day is perfectly safe, too much can be a bad thing though. The general rule is if you consume between 200 and 300 milligrams of caffeine each day you are safe, surpassing this can have negative side effects.
To put it into terms that are easier to understand, the average 8 oz cup of coffee contains about 140 milligrams of caffeine, an 8 oz cup of green tea brewed correctly will have 20 or less milligrams.

This residue left on the decaffeinated green tea leaf can cause flavor contamination, and its one more chemical going into your body. If this wasn’t enough of a reason to avoid this technique, green tea polyphenol levels drop by about two thirds after treated with Ethyl Acetate. This is not the ideal method of decaffeinating your tea, avoid products that use this method whenever possible.
The more natural but less popular option is tea decaffeinated using CO2. This process involves treating the leaves with a water and CO2 effervescence. A natural and harmless way to remove caffeine from the plant, more importantly it maintains almost all of the green tea’s polyphenol content. Making it the ideal way to decaffeinate tea, no negative side effects or harmful chemicals, while maintaining the natural antioxidant properties in the tea. Source your decaffeinated tea carefully and choose only tea’s that have been decaffeinated using this method.
