8 Best Nutrition Certifications in 2024 – cost vs value compared

Hey everybody, welcome to our International Personal Trainer Academy Nutrition Certification Review.

It’s helpful to have a go-to list comparing and reviewing the best nutrition certifications in the industry when you’re considering getting certified yourself. Doing the work to become well informed up front can save you plenty of trouble in the long run.

This article reviews the best nutrition certifications for personal trainers, nutrition professionals, and dietitians looking to expand their expertise within their scope of practice.

In total, we will be covering:

• Course content, study materials, and required books
• Exams, exam costs, and program costs
• Continuing education credits, prerequisites, and other certification requirements

We intentionally developed this article to help you make an informed decision when choosing which nutrition specialist certification to go with. It will give you the tools necessary to evaluate your options realistically and choose a program that best suits your needs.

Let’s dive in.

Why are we qualified to recommend the top nutrition certifications?

Our International Personal Trainer Academy team is made up of a large number of fitness professionals with a range of expertise. Across our team, our members hold various nutrition certifications from a large number of certifying bodies.

Members of our team have worked as registered dietitians and provided nutrition support for a range of different clients through work at gyms, health clubs, and various other facilities. Members of our team have also earned a range of fitness related degrees and other fitness certifications. Our range of expertise allows us to evaluate the quality of nutrition certifications in a holistic sense, considering professional practice from multiple angles and across multiple settings.

Beyond that, we are also familiar with hiring norms in the industry, and have hired many coaches ourselves. So we know what employers look for when it comes to fitness and nutrition certifications.

Make sure to pick a certification that best reflects your long term career goals. If you have the capacity to do so, always go with the more challenging certification. Investing in developing your skills early on in your career will set you up for success long term.

It’s also helpful to consider the total cost of the route you’re planning to go. Pursuing a fitness certification of any type can sometimes come with hidden fees, so it can be helpful to double check the total cost of your plan up front. At a minimum, you need to purchase the exam and study materials. Purchasing extra study materials may cost more money. If you do not pass the first time you sit for the exam, you will also have to pay a retest fee to take the exam again, which can factor into the total price.

Also, many certification companies run regular sales on their certifications, so make sure that you shop around to find the most cost effective deal for the specific day you plan to purchase your certification. Just because we listed a certification as having a cheap price here in this article does not mean that it will be the cheapest certification on the day that you are searching for one to purchase. Some deals can reduce the price of a certification by over 50%.

How to Get a Nutritionist Certification

To get a nutritionist certification, you need to consider, you just need to sign up for and pass an associated exam. Any other steps are optional based on the amount of studying you personally need in order to pass the exam.

But when you are trying to figure out which certification is best for you to invest in pursuing, it can be helpful to consider all of the below factors:

Let’s take a look at accreditation and how it factors into everything.

Accreditation basically just means that a certification met a minimum standard of quality, and is sufficient to certify that an individual is able to practice in the field with the minimum acceptable level of competency.

Accreditation is issued to a certifying body by a national accrediting authority once it meets industry standards.

When it comes to health and fitness, you’ll mainly be dealing with the NCCA, otherwise known as the National Commission of Certifying Agencies.

In order for a certification to be approved, it has to have content validated by a panel of subject matter experts who are leaders in their industry. This helps ensure that the contents of the certification are aligned with the reality of practice within the profession as well as with current science.

There are, of course, other legitimate, albeit less recognized, accrediting commissions out there, such as DEAC.

Let’s look at the breakdown of accreditation from each nutrition cert.

As you can see, most of these certs are accredited by the one and only NCCA, this is the gold standard in health and fitness education in North America, and even globally in some instances.

There are, however, a couple of outliers.

As we mentioned, another popular accrediting board is DEAC, short for Distance Education Accrediting Commission.

As the name suggests, this board is structured around the authentication of distance-based learning institutions.

ISSA is one of the big cert agencies that stand primarily distance-based, hence their affiliation with DEAC.

While DEAC is not as recognized as NCCA, it is still a worthy and legitimate authority.

Then we have Precision Nutrition. Precision Nutrition isn’t accredited through any formal means, despite being recognized by professionals within the fitness industry as a valid certifying body. Supporting this, peer reviewed research papers have evaluated their program and found evidence that suggests it is effective.

Although Precision Nutrition is one of the few outliers, accreditation is important because it acts as a form of quality control. It asserts that to both the candidate and any of their future employers that the education provided and standards set by the certification are up to a certain standard.

If you’re unfamiliar with the nutrition coaching or fitness industry, it can be hard to know which certifications are considered of adequate quality and which are not. If you’re unsure, look at accreditation status.

It can also be helpful to factor certification cost into your decision making. Just because a certification is cheap doesn’t necessarily mean it’s low quality, as we detail in our article on the cheapest personal training certifications.

Here are all of the top certification’s base prices side by side.

As you can see the costs vary quite greatly.

The cheapest option is ACE, which will set you back only $379.

The most you will pay for a standard package is $999 for Precision Nutrition.

It’s also important to note that many of these options have different pricing tiers based on the study material included in the various packages. The prices provided represent a standard package. Packages with more study materials and extra certifications bundled together will cost more overall.

For example, ACE Fitness Nutrition is available in the standard, cheaper package, featuring just the e-book as well as the ebook plus hardcopy option for an extra $100.

ISSA on the other hand is an example of a certification that is presented in only one package.

In any case, we’re going to give ACE the win, simply because it is the cheapest in this category.

Kindly note that change is the only constant thing in life and these also apply to the prices of each certification. There are different promos that each certifying organization offers at different times.

You can check if any certifications are currently being offered at a discounted rate by going to their website directly.

• ISSA Nutritionist
• NASM-CNC
• PRECISION NUTRITION (via the ISSA website)
• NCSF SNS
• ACE FNS

Remember also that many of these organizations allow you to sign up for a monthly payment plan, instead of paying yearly in one lump sum. This can make it easier to afford pursuing a new certification.

It can be helpful to consider the cost of each certification package relative to what they actually offer. Some certification packages offer more study resources and study resources of higher quality than others.

Let’s take a look at the study materials on offer and rate them out of ten.

Each rating below will help you decide which certification is actually the most valuable, regardless of the ultimate price.

The course materials you’ll typically get with a standard nutrition cert are pretty minimal when compared to the CPT (personal trainer) packages you’ll typically get from each respective certifying agency. This is in part because nutrition coaching certifications are often seen as more minor add ons to personal training certifications, even in instances where nutrition coach certifications are officially standalone certifications on paper.

NCSF and Precision Nutrition do stand out, however, offering a great suite of student support resources to help you gain that edge when it’s time to take the test.

NCSF Sports Nutrition has 3 packages.

We highlighted the price of the cheapest option which is the exam only. 

However, the other tiers include a comparatively deep variety of study materials when compared to the other certs.

The variety only really kicks in with the last two tiers, but it’s pretty useful overall.

But if you really want an edge and want to increase optimize your chances of passing the exam, you should look into one of our get your hands on one of our nifty study packages. As industry leaders, our team is familiar with the type of content that certification exams care about given our team has plenty of coaching experience. We can help you navigate the test taking process effectively.

All of your effort to prepare for the exam only matters so far as it helps you to pass the exam, and to become a better coach. That pressure can make taking the exam feel intimidating. But it’s a lot less intimidating if you have an idea of what you’re getting into beforehand.

Each certification has its own requirements for passing, with different target scores and numbers of questions from one another. However, exams are normally made up of mostly multiple choice questions and are administered on a computer – whether it be a computer at a testing center or at your home done remotely.

Because certification exams are focused on professional competency, the questions asked are more often related to practical application than theory. However there are still plenty of questions asked about foundational theoretical knowledge, because that information can inform decision making and analysis of a coach who is working out in the field.

Here’s a breakdown of it all.

As you can see, these exams are pretty varied.

For example, the ISSA certs, as well as PN all, have online self-paced exams.

That means you can take go at a pace that works best for you as you go through them.

ISSA and PN are also open book examss, meaning you have full access to all your prep material as you take the test. Although this does make the exam easier, artificially inflating the pass rate, some people still do not pass on their first attempt. Some of the questions asked will require you to understand concepts on a deeper level than you would by simply memorizing information. 

For example, the ISSA Fitness Nutrition exam includes some essay and case study questions. These types of questions cannot be answered by simply regurgitating facts.

You will need to be versed in the subject matter.

The other exams on this list are administered in a more traditional sense.

Click here to have access to these study materials.

You will need to take them to a physical testing facility where they will be proctored.

You can, however, take these NCCA exams remotely and online. This is done through a live remote proctor.

Remote proctoring works through your webcam or capture device linked to your PC while you’re online.

This allows monitoring of your exam as would be the case in a real testing facility.

The exam passing grades also vary quite tremendously.

ACE is quite interesting in that each quiz is scored based on a points system rather than a percentage.

You will need a minimum of 500 points out of a possible 800. Doing the math, that equates to a 62.5% passing grade.

Others hover between the 70%-75% range.

AFPA Nutrition seems to be the most demanding with a whopping 85% minimum required to pass successfully.

ISSA Sports Nutrition has the biggest exam with a total of 352 questions.

It is made up of 3 sections.

The first one consists of 230 multiple choice questions, the second has 120 multiple choice questions, and the final section consists of 2 long-form case studies and essay questions.

This is a callback to how ISSA generally used to format their exams. It has since changed for many of their certs, which now exclusively consist of multiple-choice questions.

Just as the format and administration of each exam from each institution differ, so too does the level of difficulty.

This is important to consider for a few reasons.

Firstly, it will influence how much time you’d need to invest in studying in order to pass the test.

The harder the certification exam is, the more time you will likely need to prepare for.

However, many other factors will affect your time commitment, and we’ll get to those later in the article.

Difficulty also matters because it influences your odds of passing the exam. If you don’t pass the exam and decide to retake it later on, you’ll have to spend more money in order to do so. This can increase the financial burden of the nutrition coaching exam. This burden will only increase with each subsequent attempt you make at completing the exam.

With that said, let’s actually get into some of the exams and see just how difficult they are.

Because we don’t have comprehensive data on the nutritionist exams for each of the major certifications discussed in this article, we are using CPT exam pass rates instead, as a proxy to give you an idea of the general difficulty of certifications offered by each company that offers a personal training exam. The pass rates may differ wildly between certification types within an organization, but they likely have a very loose correlation. Having a loose correlation is a more effective means of predicting difficulty than having nothing at all to base your prediction off of.

Given that proxy variables were used, we can’t extrapolate much from this information without drawing a conclusion that’s likely to be inaccurate. However, we do know from a qualitative standpoint that the ISSA exam is open book and self paced,  which should make it easier. 

Given it is an open book, it can feel less like an evaluation of your skills and knowledge, and more of a means to actively further develop your skill set during an active exam. We can make a similar inference about any other open book tests offered from other certifying bodies.

Having effective study materials can significantly improve your chances of passing the exam.

Even if you do your best and follow an effective exam prep strategy, there’s still a chance you could fail the exam

It’s impossible to know which questions will be on the version of the exam you will take, so you could get unlucky and wind up with a batch that you happen to struggle with answering correctly. Plus, maybe the stress and pressure of actually being in the middle of the test will make it harder for you to think clearly and resultantly lower your score. There are test taking strategies you can use to mitigate this risk. But, they don’t always work.

Most exams, when failed, require you to pay a nominal retake fee that is less than the original cost of the exam. In addition to this, some organizations also have mandatory waiting periods, that force you to wait a certain amount of time before you are allowed to sit for the exam again.

Let’s break down each certification’s retest fee.

The most expensive retest fee is for the coming from ACE Fitness Nutrition Specialist certification. It costs $249 for North American test takers.

You will need to retake your ACE exam within a year of your initial attempt in order to qualify for the retest fee. Most organizations have a period in which you are still allowed to apply for a re-examination. If you don’t apply within that period, you’ll need to pay the larger fee associated with the test’s base price.

It’s also worth noting that about half of the certifications on this list allow you to retake the exam for free following your first failed attempt.

Organizations like ISSA have done this for other certification exams, but organizations like the NASM typically charge high retest fees for their other exams. 

Precision Nutrition allows a total of 5 attempts after your initial one to get it right.

After 5 failed attempts, you will need to re-enroll in the program, which can be burdensome given you’d have to re-enter the waiting list.

Thinking about having to take the exam a second time can be scary. But, you don’t have to deal with that outcome if you pass the exam your first time around. Do your best to pass. Make sure you prepare adequately and master as much of the material covered in the certification you choose as possible.

International Personal Trainer Academy has developed plenty of highly effective study prep materials that you can use to gain an advantage in your exam prep. Our exam materials were, developed by successful candidates who understand what it takes to pass the exam.

Some certifications are more popular than others. This does not inherently make a certification more valuable, nor does it inherently make you more employable in most cases, when popularity is above a certain threshold. Popularity matters in the sense that certifications employers have heard of will be more advantageous when applying to a job than certifications they have never heard of. As long as you hold a certification that is popular enough that the average employer has heard of it, you will be fine.

Of the organizations covered in our article, all are somewhat well known. Although ACE, NASM, and ISSA are the most well known.

Although it is an imperfect method, we can roughly predict general popularity by comparing google search results for different certifications. One of the key flaws in this method that reduces its accuracy is that different people use different search terms for different organization’s certifications. This also doesn’t account for people who get a certification as part of a bundle or deal with other certifications – who may not search for this specific certification directly. Additionally, the most common recent search terms related to the certification, as depicted below, differ from one another in keyword content, structure, and length.

Despite the multiple methodologic flaws in this method that prevent us from truly ranking popularity based on search results, it can still provide a ballpark idea of which certifications are on the more popular side and which are on the less popular side.  For example, you can infer that the NSCF and NESTA certifications are likely to be much less popular than the ISSA certification, because the values are so far apart. Although it’s still possible that a confounding factor is influencing this.

This data comes from how many times people search the phrases Below in Google.

Having an idea of how long you’ll end up studying for an exam can help you plan ahead.

Regardless of your own study speed, you always have a maximum time limit for taking the exam, which is defined by your certification exam’s enrollment period. The enrollment period is the amount of time between the date of registration or y/purchase of your cert program, to the deadline for you to actually sit for your final exam.

Enrollment periods typically range from 6 months to a year, but in some cases, they can be as high as two years and as low as 3 months. It really depends on the organization.

However, most candidates are able to complete their studying well before the enrollment period ends. 

The actual amount of time that you need to study will depend on how effectively you study, how easily you retain information, and your starting point. If you come into an exam with plenty of background knowledge, you can finish studying anywhere from a few days to a few weeks.

If you have absolutely no background knowledge and aren’t very skilled at studying or good at retaining information, it could take you many months to prepare for the exam. However, the average candidate falls somewhere in the middle, requiring only a few months of study time in order to pass a nutrition coaching certification exam.

Let’s take a look at enrollment windows first.

The enrollment period lasts about 6 months for the average nutrition coaching certification, but some organizations vary a bit.

ACE has a generous 9-month enrollment period, while PN gives you unlimited time to complete the course!

NESTA, on the other hand,  only provides you with a 3-month window, but this is aligned to the difficulty and scope of their content so it isn’t as demanding as it may appear at first glance.

For all this talk of preparation, how do you actually adequately prepare for the exam?

The most important first step when it comes to preparing to take the exam is to create and follow a plan. Taking the time to figure out how you will study will make your studying more effective in the end, which reduces your total study time.

Certifying bodies recognize this. ISSA, for example, has a built-in 10-week study planner, which culminates in you taking the final exam.

At International Personal Trainer Academy, we took it upon ourselves to create a study blueprint for our certification study packages as well.

This blueprint allows you to study in a way that really works for you and matches your own pace.

Regardless of whether you want to take a slow approach to studying or speed through it, our study plan has you covered.

It can be hard to know if your studying is really effective unless you have a means to test your knowledge as you prepare for the exam. That’s where taking practice tests come in. Our free practice tests are always available to help you assess whether you’ve been retaining the information adequately, and practice your ability to actually apply the information you have retained.

It can be helpful to understand what average wages look like for a nutrition coach. And although there are plenty of different ways to to make money in the fitness industry, nutrition coaching has the ability to either increase your existing income as a standard personal trainer or provide you with a new income stream.

This flexibility is native to working in the fitness industry, as many fitness careers tend to have a degree of flexibility that many other traditional jobs do not.

Naturally, this flexibility means that different coaches have completely different work situations and resultantly earn very different incomes from one another. Although there is a lot of variance in earnings, most coaches do tend to congregate around a certain income range.

ZipRecruiter places the average income of nutritional health coaches at $43,836 a year. 

As for hourly earnings, expect to coin in around $21-25/hour according to the same survey. This tracks to annual salary because many coaches work less than 40 hours per week of paid time. The earnings of a nutritional coach are also confounded by multiple factors so the above numbers should be taken with a grain of salt.

For example, most nutritional coaches also do fitness training work, which likely makes up part of their income, since the two practices can sometimes blend together in real world practice. Additionally, most nutritional coaching is done by licensed and registered dietitians who have higher earning potential and more job opportunities than someone with only a certification in nutrition coaching.

That being said, earnings that come out to around $43,836 per year are aligned with our team’s industry knowledge related to income norms for nutritional coaches.

All the best nutrition specialist certifications we have lined up in this article , do have their own strengths and weaknesses.

These differences among certifications stem from differences in their position statements and orientations as organizations, as well as the specific goals of their certification. Some certifications, for example, are specifically intended to prepare candidates to work with athletes. And others are not. 

It’s helpful to factor in the focus area of the certifications available to you when making your choice as to which certification to pursue.

Click here to access these detailed study materials and save yourself from stress.

From this table, we can see that most of the nutrition certs focus on the most practical aspects of applied nutrition. This makes sense because their purpose is to specifically certify that you as a candidate are fit to practice and have met the minimum standards to begin applying your knowledge to real people. Certifications that focus on higher levels of applied nutrition naturally focus more on the underlying science, but this won’t be the best fit for every candidate.

Last on our checklist for reviewing the best sport nutrition certifications is continuing education units (CEU) requirements.

Each cert has an expiration date, and to renew it once that date arrives, you will need to pay a fee as well as submit some continuing education credits.

These credits can be gained through an approved education provider.

Most of the certifying agencies approve of each other when it comes to CEUs. 

That means you could essentially use a new cert to count towards completion of credits for the renewal of a current one.

Let’s look at how each cert handles its recertification CEU requirements.

Nutrition is a factor that can significantly impact health, fitness, and a client’s ability to achieve their goals in a timely manner.

Many trainers focus specifically on helping clients through exercise coaching because that is within their scope of practice. But by expanding their scope of practice, they can become more effective coaches. They can practice coaching in a way that personal trainer certifications alone did not adequately prepare them for.

The majority of certs earned by fitness professionals fall in the realm of exercise instruction.

The best online nutrition certification programs cover broad topics like fundamentals of healthy eating, meal plans, macronutrients, micronutrients, nutrition advice, eating habits, and obesity, to name a few.

Aiming for a credential in nutrition will not only boost your value on paper and fitness trainer salary, but it will also allow you to achieve faster and more sustainable results with clients that you work with.

That’s why we’ve rounded up 8 of the best nutrition coaching certifications in the game for you to make your choice.

Hopefully, this information can help you to determine the best nutrition certification programs.

At the International Personal Trainer Academy, we feel that it’s essential to give your clients the best possible results, which often means investing in both nutrition and training certs.

A proper diet is fundamental to overall health, but a key understanding of exercise will serve you well in the current fitness industry.

That way, when you speak to clients, you have all the knowledge you need to best serve them. Being skilled in both areas will help you make more income while providing and better outcomes for the people you are aiming to help.

The biggest hurdle to all of this is that getting two certifications literally means you need to get two certifications. This means that, in most cases, you’ll have to pay more money than just getting one. This also means that you’ll have to do more studying and take more tests, which can be stressful.

Luckily, there are two organizations with comprehensive packages right now that give you both training and nutrition.

NASM has a Nutrition and Fitness bundle for $1,798, which is another attractive option. Check the NASM website as soon as you can to get the promotion or the ISSA site because these deals are often only temporary.

So with that out of the way, let’s get into specifics about the nutrition certifications.

ISSA has a strong push for more complex nutrition programming, making it great for trainers who want to work with a variety of different types of clients.

Check here for more info on ISSA Nutritionist.

Being that it is relatively new, the NASM nutrition certification still has a lot of questions unanswered.

But as part of NASM’s stable of specializations, you can be sure that it will equip you with some cutting-edge skills, backed by the most recognized name in the game.

What Precision Nutrition lacks in terms of accreditation and the recognition that comes with it, it more than makes up for in providing real practical nutrition and business skills.

This sets it aside not only in that it isn’t a traditional cert, but it’s probably the best way to equip you as a nutritionist in practice.

If you want to learn how to start an online personal training business, this or NESTA should be your top choice.

As a side note, this may actually be the best nutrition certification for recent graduates who aspire to be practicing nutritionists or registered dietitians.

Remember that only registered and licensed dietitians are able to engage in medical nutrition therapy and are adequately prepared to fully manage the nuances of a client’s diet and prescribe comprehensive plans. Nutritionists provide general recommendations and food guidance within their professional scope of practice.
