Journal ArticleDOI
Biofortified orange maize is as efficacious as a vitamin A supplement in Zambian children even in the presence of high liver reserves of vitamin A: a community-based, randomized placebo-controlled trial

TL;DR: β-Carotene from maize was efficacious when consumed as a staple food in this population and could avoid the potential for hypervitaminosis A that was observed with the use of preformed VA from supplementation and fortification.
Journal ArticleDOI
Estimating the Potential for Vitamin A Toxicity in Women and Young Children
TL;DR: The new recommendations for high dose vitamin A supplements for infants and children are unlikely to result in toxic levels even if high dose supplements are inadvertently given monthly, and it is illustrated that a constant supply of vitamin A from breast milk is vital for preventing depletion of liver vitamin A stores between high doses.
Journal ArticleDOI
Vitamin A concentrations in liver determined by isotope dilution assay with tetradeuterated vitamin A and by biopsy in generally healthy adult humans.

TL;DR: The vitamin A status in 11 generally healthy surgical patients was estimated by measuring the dilution of a 45-mg oral dose of tetradeuterated retinyl acetate and the total body reserves and liver concentrations of vitamin A were calculated.
