Marianna Duba, M.Sc., RHN

Live Cell Microscopist

Location: Kitchener

Marianna is a multilingual holistic nutritionist (English, Hungarian, Slovak) who believes that everyone has the power to take control of their health by making simple yet meaningful dietary and lifestyle changes.

She earned her Master of Science degree in Biochemistry from Queen’s University in Kingston and has conducted research in molecular biology. Her passion for holistic health developed while working in mainstream pharmacy, where she recognized the lack of focus on nutrition and lifestyle as part of a comprehensive approach to healing. This led her to complete her studies at the Canadian School of Natural Nutrition, earning the designation of Registered Holistic Nutritionist.

Marianna’s practice emphasizes Live Blood Cell Analysis, a valuable tool for identifying nutritional deficiencies, inflammation, immune challenges, and other imbalances in the body. With over 10 years of experience in live cell microscopy, she is dedicated to guiding her clients with personalized nutrition and lifestyle strategies that support lasting health and well-being.
