    • Products intended to supplement the diet, derived from one or more dietary ingredients: vitamins, minerals, herbs, amino acids. Often concentrates, metabolites, extracts, or combinations
    • Prebiotics: non-digestible food ingredients, like inulin, that promote the growth of beneficial bacteria in the gut.
    • Probiotics: live microorganisms, like lactobacillus species, that improve intestinal microbial balance
    • Omega-3 fatty acids: present in fish oils, important for preventing cholesterol formation and other health improvements.
    • Antioxidants: counteract harmful reactive oxygen species (ROS) helping cellular metabolism. Example: vitamin C, E.

    Nutraceutical Formulations

    • Various forms available (capsules, tablets, softgels, liquids, chewable, fast-dissolving strips) with controlled-release formulations being used, enabling precise medication over time.

    Major Nutraceuticals

    • Chondroitin: joint health
    • Methylsulfonylmethane (MSM), Dehydroepiandrosterone (DHEA): multiple health benefits.
    • Melatonin: sleep, cardiovascular health
    • Carnitine: sport enhancement, cardiovascular and bone health
    • Acetyl-L-carnitine: mental health, sport enhancement
    • Octacosanol/policosanol: cardiovascular health

    Manufacture and Analysis

    • Natural products, often derived from plants and animals
    • Some are endogenous human metabolites, while others are naturally present but insufficiently present
    • May be produced via chemical synthesis or fermentation (e.g., coenzyme Q10, SAMe)
    • N-3 fatty acids are usually available as mixtures, including supradietary levels

    Consumer Acceptance

    • Sociocultural characteristics impact consumer choice of functional food
    • Key factors are taste, health claims, and product quality and trust.
    • High price might limit the uptake of some products

    Functional Foods

    • Foods containing ingredients for further physiological or health benefits rather than solely nutritional ones
    • Defined in Japan (1998), concerning "Foods for Specified Health Use"
    • Functional foods can include fortified foods with vitamins, minerals, or other beneficial compounds.

    • Non-alcoholic drinks fortified with vitamins or other ingredients such as omega-3 fatty acids
    • May help with cholesterol management, bone health, or eye health

    Functional Cereals

    • Cereals (oat, barley) that can act as fermentable substrates for beneficial bacteria and sources of non-digestible carbs
    • Can be used for encapsulation materials to improve probiotic stability
    • Often involve special enhancements or different properties aiming for health or other specific improvements

    Functional Eggs

    • Interest in enriched eggs, often with omega-3 fatty acids, important fat solubles and antioxidants

    Bakery Products

    • Bakery products can deliver functional foods, providing a suitable food matrix
    • Offering quality, appearance, taste, and texture important for consumer acceptability examples: Blue Band

    Spreads

    • Cholesterol-lowering spreads gaining relevance, containing certain active ingredients like phytosterol esters for regulating cholesterol levels
    • Low-cholesterol spreads available, such as using betacyclodextrin
