Optimal serum 25-hydroxyvitamin D levels for multiple health outcomes


Bischoff-Ferrari, Heike A (2014). Optimal serum 25-hydroxyvitamin D levels for multiple health outcomes. Advances in Experimental Medicine and Biology, 810:500-525.

Abstract

Recent evidence suggests that vitamin D deficiency has harmful effects on health and that recent vitamin D intake recommendations may be associated with better health outcomes. In this chapter, evidence is summarized from different studies that evaluate threshold levels for serum 25(OH)D levels in relation to bone mineral density (BMD), lower extremity function, dental health, risk of falls, fractures, cancer prevention, incident hypertension and mortality. For all endpoints, levels in the deficient range (< 50 nmol/l; < 20 ng/ml) are associated with no benefit or adverse effects, while the most advantageous serum levels for 25(OH)D appeared to be close to 75 nmol/l (30 ng/ml). An intake of 800 IU (20 microg) of vitamin D3 (cholecalciferol) per day for all adults may bring 97% of the population to level of at least 50 nmol/l and about 50% up to 75 nmol/l. Thus, higher doses of vitamin D than currently recommended are needed to bring most individuals to75 nmol/l. While estimates suggest that 1600 to 2000 IU vitamin D3 per day may successfully and safely achieve this goal, the implications of higher doses for the total adult population need to be addressed in future studies.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
