How to Choose The Best Health Coaching Certification Program


A comparison of top online health coaching programs (plus 3 important questions to ask yourself before deciding)

Have you noticed that we’re becoming increasingly health-conscious, collectively? 

Healthy foods, products, and habits are all on the rise compared to years past. [1]

Which means greater demand for health coaches as people begin prioritizing their health. In fact, the global field of health coaching has grown to be worth over 7 billion in recent years, and it shows no sign of slowing down!

There really couldn’t be a better time to start a career as a health coach. Especially as people move away from conventional medicine & embrace cash-pay models in record numbers, making it easier to grow your own online health coaching business.

But, how do you figure out which health coaching program is right for you?

It’s a common question we get from potential students!

So today we’re going to look at 7 top health coaching certification programs, and how they compare to our functional practitioner certification course. 

Because when it comes down to it…we want you to choose the program that’s best for YOU. 

If that’s us, great! But if not, we want to help steer you in the right direction. 

All of the programs we’ll review today are 100% virtual (no in-person requirements), making them accessible & convenient to almost anyone! 

There are many health coaching programs on the market, but today we’re going to focus on:

  • Institute of Integrative Nutrition (IIN)
  • Functional Medicine Coaching Academy (FMCA)
  • Health Coach Institute (HCI)
  • Nutrition Therapy Association (NTA)
  • Kresser Institute 
  • Health Coach Institute (HCI)

But first, allow us to introduce ourselves in case we haven’t met before!

We’re Functional Diagnostic Nutrition (FDN)

We offer a 6-12-month practitioner certification course that provides students with everything they need to transform people’s lives using the power of functional lab testing + highly personalized diet & lifestyle protocols. 

As pioneers in the field of functional lab testing, we give you the expertise you need to determine which lab tests to order, and how to interpret the results so you can create highly-effective protocols to help your clients overcome chronic health problems. 

And, equally as important, we provide you access to order these functional tests upon graduation, even without a license. Yes, anybody (including you!) can order functional testing through our Medical Director Program upon graduating.

Last, but certainly not least, we teach you how to build a thriving online wellness practice so you can make a living doing what you love. 

Here is the FDN Practitioner Certification Course, at-a-glance.

Now that we’ve laid out the details of our program, you’re probably wondering:

 “What makes this different from other health coaching programs?”

Health Coach Certification Programs vs. FDN Practitioner Certification.

While we don’t refer to our practitioner certification course as a “health coaching program”, we do see it as a strong alternative to other health coaching programs on the market!


Simple – it provides you with the expertise you need to effectively address virtually any chronic health conditions out there. 

The overall goal is the same across all health certification programs: to provide you with the expertise & skills you need to help people live healthier lives. 

But we teach you to do that by performing a deep-dive investigation of all the causal factors of dysfunction using functional testing, whereas most health coaching programs focus more heavily on coaching strategies such as positive psychology, for example. 

To decide which is a better fit for you, you’ll want to think about whether you prefer operating your own independent practice & running your health investigations, or if you’d prefer partnering with another clinician who handles lab testing & analysis. 

Both paths are available to you, at similar price points! 

Let’s have a look at seven well-known health coaching programs and see how they stack up.

Health Coaching Certifications | Program Comparisons

1 | Institute of Integrative Nutrition (IIN) 

The IIN program covers a variety of subjects including nutrition, lifestyle medicine and functional medicine. Similar to FDN, they embrace bio-individuality, teaching that everyone’s needs are different and what works for one person won’t necessarily work for another. Throughout the program, they help you “develop your personal approach to life and health coaching that honors your unique body, and how to apply this approach with others to spark their own transformation.”

Three Important Questions to Ask Yourself Before Deciding on a Health Coaching Certification Program.

  1. Do you have a desire to run your own wellness business?

If you’d prefer to run your own business (as opposed to working for a clinic or doctor), having access to functional testing is a major benefit! 

It allows you to offer more comprehensive services & higher value to your clients, so be sure to factor this in when making your decision. 

And take note about how much business development support is available to you as a graduate. It’s a lot of work to start & grow a wellness practice, so having someone to show you the ropes is a major game-changing benefit. 

FDN offers ongoing business development support to graduates for only $99/mo.

  1. Which do you enjoy more? The investigative nature of running functional lab tests & analyzing the results, or supporting clients through accountability, encouragement & positive psychology? 

If you prefer the investigative nature of running labs & cracking the case for your clients, you should definitely consider looking for a program that trains you in how to interpret functional labs, and provides you access to order the labs upon graduation. 

That’s our specialty at FDN! 

  1. What are your income goals as a health coach / practitioner? 

If you’re interested in a particular program, look up some of the graduates online. If they’re running their own businesses now, what are they charging? Also, don’t hesitate to ask program advisors what the income range is for graduates of their program. It’s going to vary by location, but they should be able to provide a general range for you. 

Keep in mind that the ability to offer functional testing to your future clients is going to massively increase the amount you can charge for your services. Most of our graduates offer high-ticket transformational programs, many that equate to $150-$200+/hr.
