About Dr. Josh Leichtberg, M.D.

Dr. Josh Leichtberg is a well-known internist and author. He specializes in Internal Medicine, with special focus on clinical nutrition, metabolism and obesity, and he has over twenty years' experience helping patients deal with these and many other difficult health issues.

Dr. Leichtberg began his innovative work in nutritional and metabolism research as director of a medical group in Calabasas and Beverly Hills, California. It was there that he developed BioSlim, the natural weight loss system that became one of the country's most popular programs.

But he had a small problem when it came to beverages—there was nothing he could buy in the store for his family that he considered acceptable. So he set out to solve that problem by creating a drink that is pure, all-natural, and contains no caloric or artificial sweeteners. But this drink had to be very flavorful, refreshing and super-healthful to boot.

Sparka is the ultimate result of the doctor's quest—a true beverage breakthrough, completely unique in today’s marketplace.
