Abstract

Vitamin A deficiency (VAD) is a major health problem, particularly in low-resource countries, putting an estimated 125-130 million preschool-aged children at increased risk of morbidity and mortality from infectious diseases. Vitamin A supplementation reduces VAD and increases child survival; it is complemented by fortifying foods with vitamin A. Concern over increased risk of bone fracture associated with vitamin A intakes below the tolerable upper intake level (UL) among populations in affluent countries conflicts with the need to increase intakes in less developed countries, where populations are at greater risk of VAD and intakes are unlikely to reach the UL as diets include fewer foods containing retinol while vitamin A from carotenoids poses no risk of overdose. With the implementation of recently developed risk management tools, vitamin A can be used safely in food fortification, including point-of-use fortification in the context of supplementation among specific target groups in low-resource countries.
