Functional Nutritionist Course

4,3

The Functional Nutritionist Course gives you the clinical tools to move beyond symptom management and address the root causes of chronic health conditions through nutrition. You'll master biochemistry, client assessment, and protocol design across eight comprehensive core chapters. This is the training that transforms knowledgeable practitioners into confident, results-driven functional nutritionists.

Dedika for businesses

What you will learn:

You will build a deep understanding of nutritional biochemistry, systems biology, and the functional nutrition matrix used to map client imbalances. You will learn how to conduct thorough health history intakes, interpret functional lab results, and administer dietary assessment tools. The course covers gut health, hormonal balance, and condition-specific protocols for metabolic syndrome, autoimmune conditions, and women's health. You will also design elimination and reintroduction protocols, targeted supplementation strategies, and therapeutic dietary frameworks. By the end, you will have the skills to build and grow a professional functional nutrition practice.

    Covers digestion, absorption, and cellular metabolism of carbohydrates, proteins, and fats. Connects metabolic pathways to energy regulation and clinical imbalances.

  • Lesson 2 • Oxidative Stress and Antioxidant Systems

    Explains reactive oxygen species generation and endogenous antioxidant defences. Students connect oxidative burden to chronic disease risk and dietary strategy.

  • Lesson 3 • Micronutrient Functions and Cofactors

    Details the enzymatic roles of vitamins and minerals in metabolic reactions. Students identify deficiency patterns linked to specific biochemical disruptions.

  • Lesson 4 • Inflammation Biochemistry

    Examines pro- and anti-inflammatory signalling cascades and their dietary modulators. Students identify nutritional levers that shift inflammatory tone.

  • Lesson 5 • Detoxification and Biotransformation

    Covers hepatic phase I, II, and III detoxification and nutrient cofactor requirements. Students design dietary support for each detoxification phase.

Chapter 3See details

Comprehensive Client Assessment

  • Lesson 1 • Dietary Assessment Methods

    Compares food recall, food frequency, and food diary tools for accuracy and clinical utility. Students select and administer the appropriate tool for each client type.

  • Lesson 2 • Functional Lab Testing Overview

    Introduces specialty and standard lab panels used in functional nutrition practice. Students interpret results within a functional reference range framework.

  • Lesson 3 • Symptom Questionnaires and Scoring

    Covers validated symptom questionnaires used to quantify functional imbalances. Students score and interpret questionnaires to prioritise clinical focus areas.

  • Lesson 4 • Synthesising Assessment Data

    Integrates history, dietary, lab, and questionnaire data into a unified clinical picture. Students produce a prioritised problem list using the functional matrix.

  • Lesson 5 • Functional Health History Intake

    Teaches a timeline-based health history method that captures antecedents and triggers. Students conduct and document a full intake interview.

Chapter 4See details

Gut Health and the Microbiome

  • Lesson 1 • Dietary Fibre and Prebiotic Strategies

    Covers fibre types, fermentation dynamics, and prebiotic food sources. Students build fibre-forward meal plans tailored to microbiome restoration goals.

  • Lesson 2 • Microbiome Composition and Function

    Examines microbial phyla, diversity metrics, and key metabolic outputs of the gut microbiome. Students link microbial imbalances to systemic health outcomes.

  • Lesson 3 • Intestinal Permeability and Barrier Function

    Explains tight junction physiology and factors that compromise intestinal barrier integrity. Students identify dietary and lifestyle drivers of increased permeability.

  • Lesson 4 • Probiotic and Fermented Food Protocols

    Reviews probiotic strain specificity, clinical evidence, and fermented food integration. Students match probiotic strategies to specific gut imbalance presentations.

  • Lesson 5 • GI Anatomy and Digestive Physiology

    Reviews gastrointestinal anatomy, digestive enzyme activity, and nutrient absorption sites. Provides the anatomical foundation for all gut-focused interventions.

Chapter 5See details

Hormonal Balance Through Nutrition

  • Lesson 1 • Insulin Regulation and Blood Sugar Balance

    Covers insulin signalling, glycaemic response, and dietary factors driving insulin resistance. Students design low-glycaemic meal frameworks for metabolic clients.

  • Lesson 2 • Circadian Nutrition and Hormonal Rhythms

    Connects meal timing, light exposure, and circadian biology to hormonal regulation. Students apply chrono-nutrition principles to optimise hormonal outcomes.

  • Lesson 3 • Thyroid Function and Nutritional Support

    Reviews thyroid hormone synthesis, conversion, and key nutrient cofactors. Students identify dietary patterns that impair or support thyroid function.

  • Lesson 4 • Sex Hormone Balance and Estrogen Metabolism

    Covers estrogen synthesis, metabolism pathways, and dietary estrogen modulators. Students design protocols for estrogen dominance and androgen imbalance.

  • Lesson 5 • HPA Axis and Stress Hormones

    Examines hypothalamic-pituitary-adrenal axis function and cortisol rhythm disruption. Students apply adaptogenic and nutrient-based strategies to support adrenal health.

Chapter 6See details

Functional Nutrition Protocol Design
