Should I See a Dietitian or Nutritionist? (And Why The Difference Matters)
I was recently asked, “Should I call you a dietitian or a nutritionist?”
It wasn’t the first time I had been asked this and if you’ve spent any time online searching for nutrition support, you’ve probably wondered the same thing.
The short answer? I’m a Registered Dietitian.
While I’m not the type of person to correct someone who calls me a nutritionist, there is actually a significant difference between the two titles. If you’re looking for evidence-based guidance, especially during key life stages like trying to conceive, pregnancy, or feeding littles, knowing who you’re working with matters.
Think of it like the geometry rule, “Every square is a rectangle, but not every rectangle is a square.”
Every dietitian is a nutritionist, but not every nutritionist is a dietitian.
What is a Dietitian?
aka Registered Dietitian (RD) or Registered Dietitian Nutritionist (RDN)
A dietitian is a nationally credentialed healthcare provider and nutrition expert. To earn and hold the RD credential, a practitioner must:
Have advanced education. As of 2024, all RDs must complete a minimum of a Master’s degree in clinical nutrition or a related health science from an accredited university program.
Complete supervised practice. This is a 1o00+ hour clinical internship which covers acute hospital care, outpatient counseling, community health, and foodservice management.
Pass a national board exam. This exam is a comprehensive exam covering medical nutrition therapy, biochemistry, and food science.
Maintain ongoing credentialing. This requires 75 hours of continuing education every 5 years to ensure up-t0-date knowledge.
Hold state licensure. RDs are licensed and regulated in most states which allows us to provide Medical Nutrition Therapy (MNT).
What an RD Can Help You With
RDs have the knowledge and education to support:
complex hormonal and metabolic conditions (like PCOS/PMOS, insulin resistance, and thyroid health)
preconception, pregnancy, and postpartum recovery
gastrointestinal disorders (IBS, IBD, celiac disease)
cardiovascular disease and diabetes management
disordered eating and improving your relationship with food
As a bonus, because RDs are recognized healthcare providers, their services are often covered by insurance and/or eligible for payment through HSA/FSA funds!
What is a Nutritionist?
“Nutritionist” is a broad title used to describe someone who offers guidance on food, eating habits, and lifestyle choices to support general well-being.
The most important distinction is that the title “nutritionist” is entirely unregulated.
There is no single standardized educational requirement, board exam, or governing body required to use the title. That means a “nutritionist” might be:
a practitioner with a Master’s or PhD in Clinical Nutrition
someone who completed a short online certificate program
an influencer or self-taught wellness enthusiast whose advice relies on personal anecdotes or social media trends rather than clinical research
While there may be nutritionists out there who are highly educated and knowledgeable, the title alone does not guarantee a specific level of clinical training, medical knowledge, or safety oversight.
4 Questions to Ask Before Choosing a Nutrition Professional
If you are seeking personalized care, you deserve to know that your care team is qualified to support you. Before booking an appointment or during your Discovery Call, consider asking a potential provider these questions:
What are your credentials and degrees? (Look for credentials like RD, RDN, PhD, or MS)
Are you licensed to practice in my state?
What is your experience with my specific health concern? (For example, do they specialize in reproductive health, pediatric nutrition, or PMOS?)
What is your approach to nutrition and food? (Ensure their philosophy aligns with your values)
Nutrition shouldn’t feel like navigating a minefield. You deserve nutrition advice that makes your life easier, not more stressful. Working with a Registered Dietitian can give you clear, evidence-based care that actually fits your lifestyle.
When in doubt, don’t hesitate to ask a provider about their background. A qualified practitioner will always be happy to share their credentials, training, and evidence-based approach to care.
