Registered Dietitian Database: How Nutrition Companies Reach 75,075 Dietitians

The registered dietitian database has 75,075 records across all 50 states and DC. Dietitians are unusual among healthcare professionals because many of them influence what patients buy and use rather than purchasing anything directly, and that changes how you should approach them.

What is in the file

Each record includes the dietitian's NPI number, practice address, phone number, fax number, license number, and credential. Dietitians who bill under an NPI appear in the NPPES registry, which is the source for this file.

Who uses it

Professional channel supplement brands and medical nutrition product companies use the file to find dietitians who recommend products to patients. Meal delivery and medically tailored meal companies use it to build referral relationships. Diabetes management, weight management, and wellness app companies use it to reach clinicians who could recommend their tools, and nutrition software vendors use it to find private practices that need scheduling, charting, and billing support.

Recommenders, not purchasers

A dietitian may never buy your product, but a dietitian who trusts it can send you many customers. That makes the pitch different from selling equipment to a dentist. Lead with clinical evidence, sample programs, and how you make a dietitian's job easier, and be ready for a longer, relationship driven conversation. A short, specific message about one clear benefit usually beats a broad brand introduction.

Where the dietitians are

California has 8,242 registered dietitians in the file, followed by Texas with 5,495, New York with 5,361, and Florida with 3,789. Pennsylvania and Illinois come next, each with more than 3,000.
