Category 03

Adaptogens

A contextual overview of the adaptogen concept as defined in pharmacobotanical literature. Covers the historical development of the term, the principal plant species studied in this category, and the current state of scientific understanding regarding the compounds identified within them, without making functional or therapeutic claims.

Historical and definitional context of the adaptogen concept in nutritional science
Overview of commonly studied plant species including Panax ginseng and Withania somnifera
Description of principal bioactive compound classes found within adaptogenic plants

Glass dropper bottles with clear and amber liquids surrounded by green botanical leaves and dried flowers on a natural linen background

Category 04

Plant Extracts

An educational description of the general category of standardised plant extracts, covering extraction methods, the concept of standardisation by active constituent, and the relationship between whole plant preparations and isolated phytochemical fractions. Explores the diversity of extract types and their position within regulatory frameworks.

Description of major extraction methods and their effects on phytochemical profiles
Context on standardisation ratios and their role in supplement manufacturing
Overview of regulatory classification of plant extracts in the EU and internationally

Vibrant purple blueberries, red pomegranate seeds and dark cherries arranged in small ceramic bowls on a slate stone surface with natural light

Category 05

Antioxidants

An informational overview of antioxidant compounds in the context of oxidative biochemistry. Describes the concept of reactive oxygen species (ROS) and how the body's antioxidant defence systems function. Covers dietary antioxidant classes including polyphenols, carotenoids, and antioxidant vitamins (C and E) in a scientific, non-prescriptive framework.

Scientific description of oxidative stress mechanisms and endogenous antioxidant systems
Overview of dietary antioxidant compound categories and their structural diversity
Context on research methodologies used to study antioxidant activity in vitro and in vivo

Selection of high-fiber whole foods including artichokes, onions, garlic, chicory root and rolled oats arranged on a wooden surface

Category 06

Prebiotics

An educational description of prebiotic compounds, covering the ISAPP consensus definition of prebiotics, the principal prebiotic fibre categories (inulin, FOS, GOS, pectin, resistant starch), and the relationship between prebiotic intake and gut microbiome composition. Distinguishes prebiotics from probiotics and synbiotics within a nutritional science context.

Definitional context for prebiotics, probiotics, and synbiotics in nutritional science
Overview of major prebiotic fibre categories and their fermentation characteristics
Description of the relationship between dietary fibre diversity and gut microbiome research
