Jennifer Greer, ND, MEd

Jennifer L. Greer, ND, MEd is a licensed naturopathic physician, scientific advisor, and independent consultant with more than two decades of experience spanning integrative medicine, clinical practice, and the nutraceuticals industry. Her work sits at the intersection of microbiome science, women's health, and evidence-based nutrition, areas she has translated across clinical, educational, and industry contexts throughout her career.

Dr. Greer currently provides medical and scientific advisory services to ingredient suppliers and consumer health brands, supporting scientific communications, evidence evaluation, and educational content development for the U.S. and international markets. She is particularly focused on helping companies bring rigorous science to their microbiome, gut health, and women's health portfolios, from ingredient assessment through post-market substantiation.

Prior to launching her consultancy, Dr. Greer served as Senior Director of Medical Education at Thorne, a science-driven wellness company serving more than 5 million customers and 47,000 healthcare practitioners worldwide. In that role, she led the development of clinically grounded educational programming for practitioners, consumers, and internal teams, building the kind of cross-functional scientific literacy that she now brings to her advisory practice. Before her transition to industry, Dr. Greer maintained a private practice in Los Angeles focused on functional gastrointestinal disorders, women's and children's health, hormone optimization, and botanical medicine.

Dr. Greer earned her doctorate in naturopathic medicine from Sonoran University of Health Sciences, graduating with the institution's highest academic honor, and completed a CNME-certified residency in naturopathic general medicine at the National University of Natural Medicine in Portland, Oregon. She also holds a Master of Education from the University of Arkansas and a BA from Ouachita Baptist University.

She has co-authored peer-reviewed research, including the 2011 Update to the Compendium of Physical Activities and original research on kavalactones, and has presented at industry and professional conferences on microbiome science, prebiotics, and women's health.
