Bioavailability, i.e., the fraction of absorbed and utilized micronutrients, is particularly important for nonheme iron and provitamin A carotenoids as bioavailability varies widely depending on a number of factors. Stable (nonradioactive) isotope techniques to assess bioavailability of these micronutrients have contributed significantly to a better understanding of the importance of integrating bioavailability into the development of food-based strategies to combat iron and vitamin A deficiencies. In this article, the authors discuss the basic principles of stable isotope techniques to assess bioavailability of nonheme iron and provitamin A carotenoids and highlight important findings based on these techniques to move the agenda forward.
