What Does a Nutritionist Do?

The main role of a nutritionist is to educate clients and the public on diet and nutrition.

It’s important to mention, nutritionists and dietitians aren’t the same. Nutritionists can only provide general diet and lifestyle advice while dietitians can work with clients with medical illnesses.

Nutritionists can work full-time in both public and private contracted roles. You can also become self-employed, working with your own clients 1-on-1.

Here’s a brief overview of the nutritionist job description:

  • Create personalised nutrition plans
  • Work 1-on-1 with clients
  • Educate the public on diet & nutrition

  • Help clients make healthier choices
  • Advise sport professionals on how diet impacts performance

Step-by-step guide to Becoming a Nutritionist

How Much Can a Nutritionist Earn?

Using salary data collected by Glassdoor, Nutritionists in Ireland can earn anywhere between €28,000 to €44,000, with an average salary of €32,000. Salaries vary between contracted employment and freelance as working freelance allows you to take on as many clients you want and work the hours you choose.

For those who are experienced, you can typically earn more. Salary Expert states a nutritionist with 8 or more years of experience can earn  around €54,992.

Factors like location, experience, and number of hours worked also influence earnings. For example, those working as nutritionists in cities such as Dublin often earn more than those working in rural areas.

Of course, experience and advanced qualifications will give you access to higher paying jobs and progression opportunities.

For freelance nutritionists, these qualifications give you access to a wider client pool, allow you to offer additional services, and charge more by marketing yourself as a specialist.

  • Your Study Method – Online courses are typically cheaper than in-person or fast-track options

  • Payment Method – Some providers offer a discount if you pay the course fees in full

  • Interest Rates – If paying in instalments, keep costs down by looking for 0% interest plans

  • Hidden Fees – Cheap courses aren’t always the bargain you think, many have hidden fees for things like resits and certificates
  • Marketing – Cost does not always equal quality, some providers set higher prices to make you think that their courses are the best
