I found some instant iced green tea - flavored and artificially sweetened - made by Lipton - sold in containers like those for Crystal Light:

In the past I’ve bought a can of quality green tea (individual serving bags within the can), made a strong batch of tea by seeping the bags in hot water and then pouring over ice to make iced tea. But the instant stuff is more convenient and tasty.
Does the instant green tea lose some of the benefits of “regular” green tea?
