Javita is a weight loss coffee. It comes in instant coffee sticks and you substitute your regular coffee drinking with it. There's no rules or instructions to follow as far as, it must be drunk so many minutes prior to eating or after eating, etc.... It's really easy. It doesn't taste super great black. Not terrible, but I prefer to add a little cream and sugar. It has organic coffee & 2 herbs in it. Garcinia Cambogia & Yerba Mate. They provide energy, and serve as an appetite suppressant. I am loving it so far!
