The Committee concluded that the prevalence of vitamin D inadequacy in North America has been overestimated and urgent research and clinical priorities were identified, including reassessment of laboratory ranges for 25-hydroxyvitamin D, to avoid problems of both undertreatment and overtreatment.

The evidence supported a role for these nutrients in bone health but not in other health conditions, and there is emerging evidence that too much of these nutrients may be harmful.
Beta-carotene is an important vitamin A source for humans.
Experts in the field of carotenoids met at the Hohenheim consensus conference in July 2009 to elucidate the current status of β-carotene research and to summarize the current knowledge with respect…
Cytochrome P450s in the regulation of cellular retinoic acid metabolism.
Taking pharmacological approaches to limiting the activity of CYP26 enzymes may extend the half-life of RA and could be useful clinically in the future.
Use of quantitative molecular diagnostic methods to assess the aetiology, burden, and clinical characteristics of diarrhoea in children in low-resource settings: a reanalysis of the MAL-ED cohort…

The results imply that plasma retinol concentration is a poor indicator of vitamin A status during inflammation, and infer that inflammation-induced hyporetinemia results from a reduction in the hepatic synthesis of RBP and secretion of the ret inol-RBP complex.
Retinoid production and catabolism: role of diet in regulating retinol esterification and retinoic Acid oxidation.

The regulated expression of LRAT, CYP26 and other genes by RA may provide a sensitive response mechanism that overall serves to adjust the metabolism of vitamin A to maintain retinoids homeostasis and prevent retinoid excess.
Regulation of hepatic retinol metabolism: perspectives from studies on vitamin A status.
Lecithin:retinol acyltransferase (LRAT) and CYP26 serve as two molecular mechanisms, coordinately regulated by all-trans-RA, to control the availability of retinol and RA, respectively.
