- Listening skills and teaching ability.
- Ethics and awareness of the limits of the practice.
How to become a nutritional therapist: training and career path
There is no state diploma; the quality of the training and your starting background make the difference:
Being a dietitian or healthcare professional, or having a solid grounding in nutrition, greatly strengthens your credibility.
Specialist schools and institutes offer courses in nutritional therapy / micronutrition (1 to 2 years), covering biochemistry, micronutrients and client support.
Stress, digestion and the microbiome, sport, perinatal care: plenty of promising niches.
Your own practice, online consultations, workshops: remote support is growing fast.
What salary can a nutritional therapist expect?
