JJ Virgin has helped whip plenty of A-list celebrities into shape. She recently appeared on KCAL TV in Los Angeles, where she shared one of her favorite tips for getting a healthier digestive system: Sunfiber. In addition to supporting the good bacteria in your gut, Sunfiber is the only “true regulating” fiber on the market. It’s an odorless and tasteless powder that dissolves very easily in your favorite beverage so it’s super easy to use. Unlike other fiber products, it won’t get lumpy or thicken the beverage. As an added bonus, it improves absorption of minerals, including calcium, iron and zinc. Other fibers often decrease absorption rates.
