Nutrient Bioavailability

Nutrient Bioavailability can be referred to as the balance of a nutrient that is absorbed from the diet and used for common body roles. There are various steps of the metabolic pathway where variations in nutrient bioavailability may happen. They are, removal of the nutrient from the physicochemical dietary model, consequences of digestive enzymes in the intestine, coupling and uptake by the intestinal mucosa, substitution over the gut wall (passing through the cells, in-between them or both) to the blood or lymphatic flow, systemic circulation, systemic deposition (stores), metabolic and functional use and discharge (via urine or faeces).
