About Marcia Zimmerman

Marcia Zimmerman’s earliest training was in medical technology and she worked in hospital laboratories where she studied living cells going about their business. Her special areas of interest were microbiology, histology, and biochemistry.

Marriage and the birth of three sons found Marcia re-directing her interest into education and she earned a post graduate degree in education and a California Life Credential in chemistry, biology and mathematics. She taught these subjects for several years. In time, the lure of molecules and a position in the lab the pediatrics department at Stanford University Medical School, got her back among the test tubes.

The pediatric research team, who was studying cancer and enzyme biochemistry, maintained strictly optimum levels of macro and micro nutrients for the living cells they were culturing and for the mice that were used in their research. In Marcia’s words, “it began to dawn on me that each of the 100 trillion cells within the human body needed that same level of nutrition if they were to survive.”

This realization sparked Marcia’s study of nutrition and when her parents decided to retire, Marcia, her husband Jon, and sons bought their health food store. She asserts, “I was intrigued by all the bottles of nutrients and determined to learn how each contributed to optimum cellular function.” She worked with children, many of whom had behavioral and learning disorders. She also guided parents and other adults in choosing a “super nutrition” regimen to jump start their journey back to health. It was extremely rewarding but a larger audience waited outside her small store.

Marcia’s next move was back to school to earn an advanced degree in nutritional biochemistry. She also wrote coursework for a distance learning program to certify nutritionists. She became an expert in the use of dietary supplements and dietary measures to correct biochemical imbalances – before they caused trouble. In applying all the biochemical knowledge she had accrued, she designed programs with a specific desired outcome that suited a vast number of people.

Marcia’s emphasis has always been on research rather than clinical work. She has authored several books that appeal to an international audience. She has lectured throughout the United States, Canada, and Europe. According to Marcia, “information is so much more accessible today with the Internet. I use this tool for research, and to communicate and educate.” We note that she also maintains an active speaking schedule and media tours as each of her books is released.
