    Study Notes

    Bioavailability Phases

    • Bioaccessibility involves breaking down a nutrient from its food matrix.

    Bioavailability Factors

    • Factors that increase bioavailability are called enhancers.
    • Inhibitors are factors that decrease bioavailability.

    Vitamin-Iron Interaction

    • Vitamin C improves the absorption of nonheme iron.

    Enhancers and Inhibitors Balance

    • When enhancers and inhibitors cancel each other out, bioavailability remains unaffected.

    Bioavailability Boosters

    • Enhancers, such as vitamin C, may increase bioavailability when added to a meal.
