About Medifast

Medifast’s operations are primarily conducted through two wholly-owned subsidiaries, Jason Pharmaceuticals, Inc. and Take Shape for Life, Inc.

History of Jason Pharmaceuticals, Inc.

William Vitale, MD, founded Jason Pharmaceuticals, Inc. in 1980. This subsidiary’s primary focus is the development, manufacture and distribution of the Medifast program and Medifast products. Medifast is a medically supervised weight loss program, which specializes in multidisciplinary patient education programs and uses the highest quality meal replacements.


Medifast offers a wide spectrum of weight management options depending on the amount of weight customers have to lose. The Medifast philosophy is meal replacement. The more meals you replace, the more weight you lose. Unlike other diets, Medifast provides life changing behavior modification programs and products that support customers through weight loss and weight maintenance. The Medifast program teaches people how to lose weight and keep it off for life.


The Medifast brand has been recommended by over 15,000 physicians nationwide and used by more than 1,000,000 customers. Medifast products are manufactured to exacting specifications in our state-of-the-art production facility in Owings Mills, MD. Product labeling, quality control and manufacturing processes and equipment are subject to regulations and inspections mandated by the Food & Drug Administration (FDA), Maryland State Department of Health and Hygiene and Baltimore County Department of Health. The plant strictly adheres to all cGMP practices and has proudly maintained its status as an “OU” (Orthodox Union) Kosher-approved facility since 1982.


Medifast offers more than 50 years combined knowledge in our experienced and dedicated customer service and technical, nutritional support staff.
