No calories. Made from green & black tea leaves. Natural peach flavors with other natural flavors. Take a gulp. Yep, it's a diet. That's what's cool about Snapple Diet Teas. They're made from the best stuff on earth. We use green and black tea leaves with natural antioxidants (contains 71 mg per 1 cup serving/40 mg per bottle of natural antioxidants [as tea polyphenols]) and filtered water. And zero calories. So go ahead, take 5 gulps. Our real tea starts with the finest tea leaves.
