Zest Tea Sparkling Teas. This is neither your calming cup of tea nor your jitter-inducing cup o’ joe. Zest Tea’s high-octane ready-to-drink teas contain 150 milligrams of caffeine (the amount in approximately 1½ cups of home-brewed coffee) plus B vitamins and amino acids. They will tantalize your taste buds and awaken your senses in exchange for just 25 to 35 calories and 5 grams of sugar per can. The cans contain 100 milligrams of L-theanine, an amino acid that supposedly reduces the jitters and crash of caffeine and instead gives you steady alertness.
