ViSalus Sciences, which launched in 2005, calls its Body by Vi Challenge the "original 90 day challenge." The company offers 3 unique Challenge themes each year and awards prizes such as trips, spa visits, shopping sprees and gift cards to champions and finalists in six categories. Participants in the Body by Vi Challenge choose from five kits, each designed to address a specific nutritional or fitness goal. The core product in the kits is the Vi-Shape Nutritional Shake Mix along with flavor mix-ins. Some kits also include products to support metabolism, appetite suppression and energy. Anyone who participates in the Body by Vi Challenge can receive their product for free each month by sponsoring 3 or more people who purchase a kit of equivalent value.
ViSalus Sciences' Vi-Pak product line was created by Dr. Michael Siedman. Dr. Siedman serves as Director of Product Research and Development for ViSalus.
