Fortune Education’s inaugural ranking of the best nutritionist certifications for 2024 hopes to guide you in exploring this career pathway.

Our methodology

There’s great news for those interested in the world of nutrition: the field is in high demand. In fact, according to the U.S. Bureau of Labor Statistics, demand for dietitians and nutritionists is growing at a rate of 7% over the next decade, and the median annual salary is just shy of $70,000. It is also important to keep in mind that to achieve this career status, individuals oftentimes need at least a bachelor’s degree as well as advanced training; each state also has different requirements for official licensure.

Even though the nutritionist industry is continuing to grow, there is no perfect pathway toward success. However, learning more about the nutritionist world through certification is a great place to start, especially if you aren’t certain if it’s the right career for you or if you just need a refresher on the basics. 

We reviewed 25 nutritionist certification programs and have included 10 of our top choices based on our thorough methodology.

While a variety of factors were used in considering each category, these data points were used to overall judge the programs:

• Price (40%): We considered the total cost of getting certified.
• Financing options (10%): Whether a certification accepted financing—as opposed to requiring upfront payment—makes the program more accessible.
• Lending partnerships (10%): Programs that have special partnerships with financial institutions can make financing easier and can potentially offer favorable terms.
• Scholarship opportunities (10%): For those who cannot or unwilling to pay off certification through a loan, a scholarship is a good way to lower the total cost.
• Military discounts and funding (5%): We considered whether financial assistance is available for active-duty, reserve, and/or veterans of the U.S. Armed Forces.
• Continuing education credit acceptance (5%): Completion of programs can be used toward continuing education requirements in certain states in order to retain more advanced certification or licensure.
• Career coaching/mentorship/instructor support (10%): We reviewed whether each certification offers student support programs to each student to excel while learning and better prepare them for securing a job in this field.
• Average annual search volume (10%): We looked at the average number of times during a month that people search for each certification organization on Google, then converted it into a yearly metric to measure public perception of an organization’s brand and reputation and how it affected what program they were interested in attending.

Our expert panel 

We sought out those with thorough expertise in the nutritionist world for the creation of our ranking: 

• Shaina Painter, MS, CNS, nutritionist at Being Health
• Michelle Routhenstein, MS, RD, CDCES, CDN, owner of Entirely Nourished

By asking questions about the importance of nutritionist education, different types of educational pathways, and the skills needed to succeed, we hoped to better understand how to effectively guide those pursuing a career in the field. It’s noteworthy that neither expert was directly involved in ranking any programs.

Anyone can call themselves a nutritionist

Similar to the world of health coaching and other certificate programs, anyone can truly call themselves a nutritionist. However, as Painter notes, the nutritionist title is often correlated with both registered dietitians and certified nutritionist specialists.

“The nutrition professional is going to have advanced education, benchmark education, through bachelor's degrees, through master's degrees with standardized and structured information that provides safety but also efficacy in their recommendations to working one-on-one with clients,” Painter says. 

She adds that once one obtains the official licensure, which depends on the state, only then should they be suited to give personalized nutrition recommendations to clients in a clinical setting.

“Nutrition is a very nuanced space,” Painter says. “One right condition does not fit every patient. Having the ability to have critical thinking skills, the tactical knowledge of nutrition science, and also the understanding of mainstream and gold standard approaches to care, it's very important for the safety and the health of the patient.”

In terms of skills, Painter says anyone looking to get into nutrition should have:

• Excellent communication and listening skills
• An ability to relate to people from different backgrounds
• Interpersonal skills, such as empathy, compassion, and patience 
• Problem-solving capabilities 
• A deep interest in scientific knowledge, like nutrition science, biochemistry, and pathophysiology

Fighting nutrition misinformation

Routhenstein emphasizes that broad nutrition certifications focus more on holistic health like body, mind, and spirit. People with the training can be great at helping others take accountability when it comes to losing weight or learning how to eat healthy—when they do not have a past medical history.

On the other hand, clients on medication or with medical history should instead be seen by licensed dietitian nutritionists or others with a relevant academic background and clinical expertise.

“It's important that when you have a medical diagnosis—you're not just being seen by anyone, because they might not understand nutrition, they may just give you a bunch of supplements that counteract with your medications and can drive your kidney function down,” she says.

Both Routhensin and Painter say one of the most important things to the world of nutrition is curiosity and asking questions—not only about yourself but also about biology. Some questions to consider include:

• What do you want to do with your career? 
• Why do you want to help others? 
• Why do certain foods affect human bodily functions differently from a biological standpoint? 
• Why should someone eat more of something versus another thing?

Nutrition misinformation is running rampant in an era of social media dominance. In fact, a recent analysis of TikTok videos relating to diet and nutrition trends found that only 2% of the content was accurate. Because of this, Routhensin says it is more important than ever that experts are credentialed by a top governing body, such as the Academy of Nutrition and Dietetics Commission on Dietetic Registration.

Dietitians and nutritionists earn median annual salaries of about $70,000, according to the U.S. Bureau of Labor Statistics. Exact pay can vary dramatically depending on your role and educational experience.

What is the best qualification for a nutritionist?
