From an article on Newsweek:
Created by Ryan Tedder of OneRepublic and NBC’s “Songland,” Mad Tasty is a subtly-flavored low-calorie sparkling beverage with 20 mg of pure broad-spectrum hemp extract. Available in Grapefruit, Watermelon Kiwi, and their new flavor, Unicorn Tears. In partnership with Drop4Drop, for every 12 oz they produce, Mad Tasty donates 12oz of clean drinking water to people and places in need. (Note: Mad Tasty is experiencing temporary shipping delays due to increased demand.)
