Jean Elinor Carper was born January 3, 1932, the daughter of Jethro and Natella Marie (Boyer) Carper, in Delaware, Ohio. She is a 1953 graduate of Ohio Wesleyan University in Delaware, Ohio, where she majored in speech and was a member of the debate team that won a state championship.
Three of Carper's books have been on the New York Times best-seller list: Food: Your Miracle Medicine, in 1993; Stop Aging Now!, in 1995; and Miracle Cures: Dramatic New Scientific Discoveries Revealing the Healing Powers of Herbs, Vitamins, and Other Natural Remedies, in 1997. After the release of Stop Aging Now, her readers urged her to formulate an all-in-one multivitamin based on her research. By popular demand, she produced a multi vitamin anti-aging formula in 1996, called Stop Aging Now! She sold the company in 2007 and is on the company's scientific advisory board.
Her success as a medical journalist has been credited to her ability to accurately translate research in ways understandable to the average person. Her books on health have been translated into 20 foreign languages and are still sold and read throughout the world.
Carper is the author of 24 books, mostly on nutrition, health, and natural remedies, including two cookbooks.
Ohio Wesleyan University awarded her a Distinguished Achievement Citation in 1999, recognizing her work as a "major force in enlightening the public about the latest scientific discoveries involving diet, food, and vitamins as causes and cures of our modern epidemic of chronic diseases, including heart disease and cancer."
In 2014 she was inducted into The Ohio Foundation of Independent Colleges Hall of Excellence.
