How to Become a Certified Nutritionist

Step 1: Knock Out Your Prerequisites

Before you begin your nutritionist certification course, you’ll want to ensure you have the prerequisites needed to be eligible. Unlike the process to become a personal trainer, the prerequisites to become a certified nutritionist vary greatly from company to company.

Most companies that offer personal training certifications along with nutrition certifications require the below before you can sit for the final exam:

    1. 18 years or older
    2. High school diploma or GED
    3. CPR/AED certification

However, the certifications that are not associated with major fitness bodies such Precision Nutrition or Primal Health Coach do not have prerequisites in place. 

Bottom line: if you are serious about a specific course, check out their prerequisites to ensure they work for you.

Step 2: Find the Best Nutritionist Certification for YOU

As mentioned earlier, there is no “best nutritionist certification,” only certifications that are the most highly recognized. Nutrition education isn’t one-size-fits all, it’s up to you to determine what the best course is for your career and weigh all your options.

Further, consider how you learn best and how the options presented fit into your learning process. Another important consideration is time; how quickly do you want to get certified? Some options may be quicker than others and that may impact your final decision.

Step 3: Prepare for Your Exam & Pass!

Don’t overlook the importance of scheduling your final exam for your nutrition certification. Putting this off may result in long term procrastination. Still, you have to be realistic with your final exam date and your study timelines.

Once you knock out the exam and get certified, you are on your way to training with clients

Step 4: Start Landing Nutrition Clients

Now that you have a fancy certification next to your name and have learned about how to work with clients and various nutrition goals, you can master the art of helping your clients achieve their goals.

Without further ado, let’s learn about some important considerations you should be aware of as you choose the best nutritionist certification for you!
