The short answer: it depends on where you live. "Registered Dietitian" is protected nationwide and requires the CDR credential. "Nutritionist" is the wild card. Some states reserve it for licensed practitioners. Some states let anyone use it. Some states protect a specific variant like "Certified Nutritionist" or "Licensed Nutritionist" but leave the bare word "nutritionist" unregulated. Get this wrong and you can face a cease-and-desist from the state board, civil penalties, or in a few states, misdemeanor charges. This guide walks through how to read your state's law without paying a lawyer.

The two things states actually regulate

State nutrition law regulates two separate things, and conflating them is where most practitioners trip up. The first is title protection: who can use specific words on a business card or website. The second is scope of practice: who can actually do specific activities like medical nutrition therapy, ordering labs, or treating clinical conditions.

A state can protect a title without restricting scope (anyone can do nutrition counseling, but only credentialed people can call themselves "nutritionist"). It can restrict scope without protecting titles (anyone can call themselves a nutritionist, but only credentialed people can do MNT). Or it can do both. The Academy of Nutrition and Dietetics maintains a current CDR Licensure Map that's the cleanest single source on what each state does.

States that protect the title "nutritionist" 

Roughly a dozen states meaningfully restrict the unqualified word "nutritionist" to credentialed practitioners. These typically require either an RD, a CNS (Certified Nutrition Specialist), an LDN (Licensed Dietitian/Nutritionist), or a state-specific license. Examples drawing on the CDR licensure summary and state statutes:

  • Connecticut, Maine, Minnesota, New Mexico, North Dakota, Oregon: have explicit nutritionist licensure or certification statutes covering the title.
  • New York: "Certified Dietitian/Nutritionist" is a protected title under Article 157 of the Education Law.
  • Maryland, Pennsylvania, Tennessee, Illinois, Massachusetts: protect dietitian titles strongly and apply some restrictions to nutritionist titles via combined dietitian/nutritionist licensure.
  • Florida, North Carolina, South Carolina: restrict who can practice "nutrition counseling" with various exemptions.

Read your specific statute, not the summary. State boards update language regularly, and exemptions (for personal trainers, supplement retailers, religious counselors, or NANP-recognized holistic practitioners) vary widely.

States where almost anyone can use "nutritionist"

A handful of states have no nutritionist title protection at all, or have language so loose that any credentialed person, and sometimes anyone, can legally use the word. Per the CDR map, the states with the lightest regulation include Arizona, Colorado, Michigan, Montana, and New Jersey, where RD licensure itself is voluntary or nonexistent.

In these states you can call yourself a nutritionist without a credential and not be breaking title-protection law. Two important caveats. First, you can still get sued or face FTC action for misleading claims if you imply credentials you don't have. Second, even where the title is unrestricted, scope of practice may not be. Treating a medical condition with a specific nutrition prescription can put you on the wrong side of the medical-practice statute regardless of what you call yourself.

The Certified Nutrition Specialist (CNS) credential, awarded by the Board for Certification of Nutrition Specialists, is the only non-RD credential named in nutrition licensure statutes in many states. Per the ANA's state-by-state CNS practice rights document, CNS holders can secure licensure as a Licensed Nutritionist or equivalent in roughly 16 states, including Maryland, Massachusetts, Minnesota, New York, North Carolina, Pennsylvania, and others.

In those states, holding a CNS plus the state license generally gives you full title use AND practice authority for medical nutrition therapy, on par with an RD. In states without CNS recognition, the CNS by itself doesn't authorize licensed practice, though it remains a private credential you can list. See our CNS overview and our 36 CNS-pathway programs.

Where holistic credentials (BCHN, CHN, CNHP) sit

The Board Certified in Holistic Nutrition (BCHN) credential from NANP and similar holistic credentials are private certifications. They are not named in state licensure statutes (with very narrow exceptions). That means in title-protection states, holding a BCHN does not authorize you to call yourself a "nutritionist" full stop, though you can usually call yourself a "holistic nutrition consultant," "certified holistic nutrition professional," or BCHN.

NANP's legislative affairs page tracks which states actively threaten holistic practitioner scope and offers practice guidance for members. The honest assessment: BCHN is fine in unregulated states and in regulated states for clearly-scoped holistic work, but it does not unlock the bare "nutritionist" title in protected states.

How to actually read your state's law in 15 minutes

Forget aggregator articles. Go to the source:

  1. Open the CDR Licensure Map and click your state.
  2. Read the statute citation it lists. Then go to your state legislature's website and pull the actual statute text. (Statutes change. CDR's summary may lag.)
  3. Search the statute for the words "nutritionist" and "title" and "protected" and "unlawful." Read every instance.
  4. Look for the exemptions section. This is usually where you'll find out whether holistic practitioners, coaches, supplement retailers, or trainers are carved out.
  5. Check your state board's website for advisory opinions or enforcement actions. Many boards publish FAQs or Q&A that interpret ambiguous statute language.

If after that you're still unsure, $200-$400 with a healthcare-licensure attorney is cheaper than a board complaint. Many state RD/dietitian associations also offer member-only legal hotlines.

Safer language if you're between credentials

If you're a coach, holistic practitioner, or in-progress student in a title-protection state, here's language that generally stays inside the lines (verify with your state):

  • "Health coach" or "wellness coach" (most states don't regulate these)
  • "Certified Holistic Nutrition Consultant" (uses your private credential explicitly)
  • "Nutrition educator" (in states that distinguish education from counseling)
  • "Plant-based nutrition coach" or other modifier-specific titles

What to avoid in protected states: bare "Nutritionist," "Clinical Nutritionist," "Certified Nutritionist," or anything implying licensure you don't hold. Don't use "medical nutrition therapy" or "nutrition prescription" without the underlying credential, regardless of what you call yourself. See our directories for health coach programs and nutrition coach programs.

Federal vs. state: nothing federal protects "nutritionist"

There's no federal nutritionist title law. The FDA regulates food labeling and supplement claims. The FTC regulates advertising claims. Neither defines who can call themselves what. Title protection is 100 percent a state matter. This is why two practitioners with identical training can be operating legally on opposite sides of a state line and why you need to recheck the law every time you move or take on remote clients in a new state.

Telehealth complicates this further. Most states' position is that nutrition counseling is delivered "where the client is sitting." If you're CNS-licensed in Maryland and your client is in New York, New York's rules apply to that visit. Some states have telehealth-specific exemptions. Most don't. Verify before scaling a remote practice.

Frequently asked questions

Can anyone in any state call themselves a "dietitian"?

No. "Dietitian," "Registered Dietitian," and "RD" are protected nationwide via state laws and CDR's federal trademark on the credential. Using these titles without holding the CDR credential is title misuse in every state and exposes you to civil and sometimes criminal penalties.

Does an online "nutrition certificate" let me call myself a nutritionist?

In unregulated states, yes, the title is generally available. In title-protection states, no, a private certificate from a non-accredited provider does not satisfy state title-use requirements. The credentials that typically do are the RD, the CNS, or a state-issued license. See our online nutrition courses guide for what these certificates actually buy you.

If I'm licensed in one state, can I see clients in another by telehealth?

Usually no. Most states regulate the location of the client, not the practitioner. A handful have explicit cross-state telehealth allowances for nutrition. Check both your state and the client's state before each engagement. The ANA's regulations table is a useful starting point.

Is BCHN enough to call myself a nutritionist anywhere?

In unregulated states, often yes. In title-protection states, BCHN alone usually does not satisfy the title-use rule. You'd typically need to use "holistic nutrition consultant" or similar modified language. Our BCHN guide covers the credential's actual recognition.

What's the actual penalty if I use a protected title?

Usually a cease-and-desist letter from the state board first. If you ignore it, civil fines (commonly $500 to $5,000 per offense) and in a few states misdemeanor charges. The bigger long-term damage is usually reputational, especially if a board action becomes public record or shows up in a license search.
