About the IONC

30 YEARSThe International Organization of Nutritional Consultants (IONC) is a not for profit corporation established in 1983 to assure the public that member practitioners are meeting high educational standards.

As a professional  membership Association for holistic nutritionists all IONC members must adhere to IONC’s Code of Conduct, Performance and Ethics, hold professional indemnity insurance for clinical practice, have completed annual education upgrades and also meet membership entry criteria.

IONC seeks to create a unique form of Regulatory status for Nutritionists.

IONC is continuing its discussions and has  meetings  planned with government delegates in 2017 concerning regulation and recognition of Orthomolecular and Holistic Nutritionists .  It is IONC’s position that our members and the public interest would be better served if the Health Professions Regulatory Advisory Council (HPRAC) were to grant self-governing status to qualified ROHP/RNCP practitioners.  A proto-submission outlining a new improved Drugless Practitioners Act or Natural Medicine Practitioners Act is currently under development that could see the integration of our practitioners into a multi-disciplinary approach to health care in the future.  This goal may be lofty but it is the direction our organization believes to be imperative for creating legitimacy and stable practices for practitioners in a constantly changing legislative landscape.

Since 1983 our members have been Inspiring Optimal Nutrition within Communities throughout Canada and abroad. We are the founding Association for Holistic Nutritionists in Canada.

IONC’s aim is to legitimize our profession and approved schools, achieve title and scope of practice protection for our members, increase public safety, and enhance client/patient insurance coverage for ROHP/RNCP services for better client wellness outcomes.
