Becoming a nutritionist sounds like a simple, straightforward process. Because of the varying regulations from state to state, however, the process is far from streamlined. If you want to become a nutritionist (which is different than a registered dietitian nutritionist, which we cover here), there are a variety of pathways that you can take depending upon where you want to practice, the setting in which you wish to work, and the population you wish to see.
Whether you wish to work as a licensed nutritionist or a non-licensed nutritionist, there are steps that you must take in order to do so. In this ultimate guide to becoming a nutritionist, we will tell you everything you need to know about licensed nutritionists, non-licensed nutritionists, and what steps you must take in order to work in this exciting field.

State Regulations for Practicing Nutrition
Individualized nutrition counseling, excluding medical nutrition therapy in select states, is legal for all. Certain states provide state licensure or certification opportunities for CNSs, RDs, and other proficient nutritionists.
Engaging in personalized nutrition counseling without proper licensure or exemption is illegal. However, there exists a route to obtaining licensure for CNSs, RDs, and other experienced nutritionists.
Engaging in personalized nutrition counseling without proper licensure or exemption is illegal, with licensure primarily limited to registered dietitians (RDs).
*Verify the licensing and certification requirements in each state, as these regulations can change. Readers should check with state authorities or professional organizations for the most recent information.
What Is a Licensed Nutritionist?
A licensed nutritionist has obtained a license or certificate that is necessary in order to legally practice in their state. This might or might not follow a nutritionist obtaining national credentials from a nationally recognized organization. National credentialing, which we will discuss in a later section, is separate from state licensure or certification. States that do require nutritionists to be licensed often have mandates that these nutritionists must first earn credentials before licensure or certification is possible. In these states that require nutritionists to be licensed, after completing the requirements for credentialing, would-be licensed nutritionists in those states must submit information to the state’s Board of Dietetics or similar agency to gain a license. Other states might simply require nutritionists to complete education or experience, but not to gain any specific credentials.
As of May 2022, per the Academy of Nutrition and Dietetics (AND), the following states require licensing or certification for nutritionists (each state is listed along with the agency that is responsible for licensure of nutritionists in that state):
- Alabama: State Board of Examiners for Dietetics & Nutritionists
- Alaska: Division of Corporations, Business and Professional Licensing
- Connecticut: State Department of Public Health
- Delaware: Board of Dietetics/Nutrition
- District of Columbia: Health Regulation and Licensing Administration
- Florida: Dietetics and Nutrition Practice Council
- Illinois: Department of Financial & Professional Regulation
- Kentucky: Board of Licensure and Certification for Dietitians and Nutritionists
- Louisiana: Board of Examiners in Dietetics and Nutrition
- Maryland: State Board of Dietetic Practice
- Massachusetts: Board of Registration of Dietitians and Nutritionists
- Minnesota: Board of Dietetics and Nutrition Practice
- Montana: Board of Medical Examiners
- Nebraska (Medical Nutrition Therapists only must be licensed; those providing general nutrition services need no license): Department of Health and Human Services Licensure Unit
- New Jersey: State Board of Dieticians and Nutrition
- New Mexico: Nutrition and Dietetics Practice Board
- New York: Office of the Professions Board of Dietetics and Nutrition
- North Carolina: Board of Dietetics/Nutrition

- Rhode Island: Department of Health
- South Dakota: Board of Medical and Osteopathic Examiners
- Tennessee: Board of Dietitians/Nutritionist Examiners
- Washington: State Department of Health
What is a Non-Licensed Nutritionist?
Other states do not require nutritionists to become licensed in order to legally practice in the state. These nutritionists are referred to as non-licensed nutritionists. Again, this is separate from national credentials for nutritionists, which may still be earned, if desired, by nutritionists practicing in these states.
States that do not require nutritionists to hold a license or certification in order to practice there include:
Differences Between Licensed and Non-Licensed Nutritionists
| Characteristic | Licensed Nutritionist | Non-Licensed Nutritionist |
|---|---|---|
| Definition | Holds a state-issued license/certificate to practice. | Practices without the need for a state-issued license. |
| Education Requirements | Varies by state; often requires specific degrees. | No state-mandated educational prerequisites in many states. |
| National Credentials | Often required before obtaining state licensure. | Optional; can still earn national credentials if desired. |
| Scope of Practice | Defined and regulated by state laws. | May have more flexibility in practice areas. |
| Legal Restrictions | Subject to state laws governing nutrition practice. | Must adhere to general legal regulations but not licensure-specific. |
| States Requiring Licensure | Examples include Alabama, Florida, Illinois, California, etc. | Examples include Arizona, Colorado, Georgia, Michigan, etc. |
| Certifying Authorities | State-specific boards or agencies overseeing licensure. | No state-mandated certifying authority; national organizations optional. |
| Insurance Billing | Can often bill insurance for services rendered. | Limited or no ability to bill insurance in many cases. |

What Education Do I Need to Become a Nutritionist?
If you wish to practice as a nutritionist, the first thing that you should become familiar with are the regulations, if any, that govern nutritionist practice in your state. Check the list above for licensing or certification requirements in your state. This will largely determine what educational requirements you must fulfill in order to practice in that state.
Not every state will require that nutritionists complete any set education. Most states that do mandate education, however, will require a minimum of a bachelor’s degree in a field related to nutrition and dietetics.
