Best Online Nutritionist Certifications of 2022

If you’re looking to start or further a career in nutrition and wellness, then an online nutritionist course may be for you. While you can begin a career as a nutrition coach without a certification, getting one may help you move your career forward and ensure a thorough knowledge of how foods impact health. It also gives you credibility and authority with clients, helping them have confidence that you’ll be able to help them.

A good online nutrition certification program is one that was developed by health experts and backed by peer-reviewed, evidence-based scientific research.

Online nutrition certifications increase your eligibility for jobs like health coaching, nutrition coaching, or creating your own coaching business. Consider who you want to work with and your interests when choosing a certification. Programs may provide general training or more specific information on topics like plant-based nutrition or children’s nutrition needs.
