100% Natural. Serve hot or iced. With other natural flavors. The natural way to brighten your day! Lipton Raspberry Flavored Black Tea blends pure black tea leaves with natural flavors to create a sweet raspberry taste. A cup of tea has less than half the caffeine as a cup of coffee. Tea & antioxidants: You might have heard about antioxidants found in many fruits and vegetables (tea is not a substitute for fruits and vegetables, which are an important part of your diet). But did you know that Lipton Raspberry Flavored Tea has 70 mg of flavonoid antioxidants per serving? A full-bodied, flavored black tea blend with natural raspberry flavors.
