                                According to Healthline, an 8-ounce cup of standard green tea contains between 30 and 50 milligrams of caffeine. The citrus flavoring itself contains no caffeine and does not add to the tea's natural stimulant content. The final caffeine amount in your citrus green tea depends on several factors, including the brewing method and brand.
