Micronutrients & recovery
The oral bioavailability of nutraceuticals is limited by physicochemical and physiological factors including liberation from food matrices, solubility in gastrointestinal fluids, interactions with GI components, chemical degradation, and epithelium cell permeability.
To maximize health benefits from nutraceuticals (like vitamins, carotenoids, or polyphenols), consider how they are delivered. Processing methods (cooking, homogenization) and food matrices (lipid-based delivery systems) can significantly enhance the release and absorption of these compounds. Simply consuming the raw nutrient may not yield optimal results if bioavailability is limited by solubility or permeability.
The oral bioavailability of a health-promoting dietary component (nutraceutical) may be limited by various physicochemical and physiological phenomena: liberation from food matrices, solubility in gastrointestinal fluids, interaction with gastrointestinal components, chemical degradation or metabolism, and epithelium cell permeability.
Why this rating
