I am Dr. Kateryna Tolstikova, a Candidate of Medical Sciences, physician, dietitian-endocrinologist, and specialist in family, functional, and anti-aging medicine. I am an Assistant Professor in the Department of Medical Biochemistry and Molecular Biology at Bogomolets National Medical University.

With 17 years of experience in medicine and 15 years in dietetics and nutritional therapy, I combine evidence-based medicine, endocrinology, biochemistry, functional medicine, and nutritional science to help people better understand their health and make informed, practical choices about nutrition and lifestyle.

I am the author of three books, scientific publications, and methodological guidelines, as well as a speaker at international scientific conferences. I am also a member of the Institute for Functional Medicine (IFM).

I founded the educational and scientific project Dr. Tolstikova Health Academy and the Dr.Tolstikova supplement brand, where we translate complex medical and nutritional science into practical tools for everyday health.

Throughout my career, I have also worked as a personal physician and dietitian to professional athletes, including undisputed heavyweight world champion Oleksandr Usyk, MMA champion Yaroslav Amosov, FC Polissya, professional tennis player Katarina Zavatska, and others.

My goal as an educator is to make evidence-based nutrition and health science clear, practical, and applicable to everyday life.
