We review recent work in which model-based compartmental analysis has been applied to
data for theoretical human subjects in order to study questions related to vitamin A kinetics …

Background Vitamin A concentrations in breast milk are related to maternal vitamin A intake
and status. Objectives Our objective was to identify conditions under which vitamin A specific …

Background Low vitamin A status and suboptimal milk vitamin A concentrations are
problems in many populations worldwide. However, limited research has been done on …

Abstract Background Inadequate vitamin A (VA) intake is common among lactating women
in many communities worldwide, but high dose VA supplementation of postpartum women is …

Background Although the vitamin A (VA) equivalency of provitamin A carotenoids from
single foods or capsules has been studied using several approaches, there is currently no …

Background Previous compartmental models describing and quantifying whole-body vitamin
A (VA) metabolism have been developed from plasma retinol kinetic data after human …

Provitamin A carotenoids (pVACs) are important contributors to vitamin A status and in
reducing vitamin A deficiency in vulnerable populations. However, there are uncertainties …

Major strides have been made globally to eradicate blindness due to vitamin A (VA)
deficiency, but VA status assessments are still important for monitoring intervention …
