Deena Jane Kelaita

Clinical Nutritionist (BHSc Nut Med)

Deena Jane Kelaita is a qualified Clinical Nutritionist (BHSc Nutritional Medicine) and Fellow of the Australian Traditional Medicine Society (ATMS), with over 10 years of clinical experience specialising in personalised, evidence-based nutrition and functional health testing. As a certified Healthy Gut Practitioner and Microba Microbiome Guardian, she brings advanced expertise in gut and microbiome health to her work with clients — addressing the root causes of imbalance and supporting long-term health, vitality, and wellbeing.

My own journey with Crohn's disease, diagnosed at just 12 years old, gave me firsthand insight into how powerfully our gut impacts our entire body. That lived experience, combined with more than a decade in clinical practice, fuels my work today — helping others restore their health with compassion, clinical strategy, and hope.
