Targeting Registered Dietitians in the US

Registered Dietitians are one of the largest and most trusted allied health audiences in the US, and one of the hardest to reach at scale. There are around 114,000 Registered Dietitians credentialed through the Commission on Dietetic Registration, working across hospitals, clinics, community health, food service, sports and private practice rather than a single setting. They provide medical nutrition therapy and everyday nutrition guidance, and they influence the food, supplement and nutrition products their patients and clients use. Our HCP Targeting is audience-based, not Contextual, so we reach the Registered Dietitian as a clinician and as a person, wherever they browse: news, finance, technology, sport, travel, food, lifestyle and health content alike. That is broader reach across brand-safe, premium inventory, through Programmatic and Managed Campaigns, in the US.

Our HCP Targeting (including this Registered Dietitian Targeting Segment) is available in the USA only, delivered with geo-targeting to the United States.

Need to reach HCP audiences based outside the US? It’s harder, but we’ve had success targeting them through Clinical Websites and Contextual Targeting.

The Registered Dietitian Audience

There are around 114,000 Registered Dietitians in the US, a large and growing allied health workforce spread across hospitals, outpatient clinics, community and public health, food service, sports and private practice. That breadth is the point: Registered Dietitians provide medical nutrition therapy for conditions like Diabetes, Kidney Disease, Cancer, Heart Disease and Gastrointestinal Disorders, and they guide everyday nutrition, weight management and wellness. They choose and recommend the oral nutrition supplements, enteral and parenteral nutrition, medical foods, specialized formulas and dietary supplements their patients use, and they shape food and menu decisions across health systems. Because they are the trusted nutrition authority patients and clinicians rely on, they are a high-value audience for Nutrition, Food, Supplement, Pharmaceutical and Medical Nutrition brands.

Why Advertise to Registered Dietitians

Registered Dietitians sit at the point where healthcare meets food, and they shape a wide range of purchasing decisions. They recommend oral nutrition supplements like Ensure and Boost, enteral and parenteral nutrition, medical foods and specialized formulas for Diabetes, Kidney and other conditions, dietary supplements, and everyday food and beverage choices. Their influence extends well beyond a single consultation. Registered Dietitians set the formularies and menus their hospitals and health systems adopt, advise patients and families on what to buy and eat, and are trusted by the public as credible nutrition experts. Because they guide both clinical nutrition and consumer food and supplement choices, reaching the Registered Dietitian is valuable to nutrition, food, supplement and pharmaceutical brands alike.

Take an “Always On” Strategy for Targeting Registered Dietitians

Registered Dietitian TargetingRegistered Dietitians are a busy, hands-on audience, running back to back nutrition consultations across hospitals, clinics and community settings, with assessments and charting around them. You can rarely predict when one is online, whether it is between sessions, after a full day of therapy or on a weekend.

That is why we recommend an Always On strategy for an audience like this: run the campaign 24/7, 365 days a year so you reach Registered Dietitians whenever they surface, not just in a short burst. Continuous delivery builds reach and frequency over time, so you are already in front of them by the time your message matters most.

An Always On budget goes further with an Omnichannel approach. Rather than betting on one screen, you reach Registered Dietitians across the whole day: on their phone between sessions, through a podcast in the car, on the office desktop between evaluations, and on Connected TV while they unwind at home. Same audience, more moments, more chances for your message to land.
