Estimation of optimal serum concentrations of 25-hydroxyvitamin D for multiple health outcomes. (2006, background): “Serum 25(OH)D concentrations have also been related to calcium absorption, but those studies did not allow for estimation of a precise threshold (11, 12).”
Vitamin D: importance in the prevention of cancers, type 1 diabetes, heart disease, and osteoporosis. (2004, methodology): “As noted in Heaney’s McCollum Award presentation (70) and as indicated in a considerable number of published reports, including that of Heaney et al (71), the new recommendations are totally inadequate, especially if a person has no exposure to sunlight.”
Prevalence of Vitamin D inadequacy among postmenopausal North American women receiving osteoporosis therapy. (2005, background): “(14) concluded that serum 25(OH)D concentrations of 32–36 ng/ml (80 to 90 nmol/liter) may be required to attain maximum intestinal calcium absorption, whereas Malabanan et al.”
High prevalence of vitamin D inadequacy and implications for health. (2006, background): “health has been proposed as the range that reduces PTH levels to a minimum(9,11,35) and calcium absorption is maximal.(28) Several studies have shown that PTH levels pla-”
Vitamin D2 is much less effective than vitamin D3 in humans. (2004, background): “Recent studies have shown that raising serum 25OHD improves calcium absorption (19), reduces fall frequency (20), and lowers osteoporotic fracture risk (6).”
Estimates of optimal vitamin D status (2005, background): “5 nmol/l than at levels averaging 50 nmol/l [16].”
Assay variation confounds the diagnosis of hypovitaminosis D: a call for standardization. (2004, neutral): “0) [20–71] B 20 67.”
The vitamin D epidemic and its health consequences. (2005, background): “only about 20–40% as effective as cholecalciferol in maintaining serum concentrations of 25(OH)D (48,49).”
Vitamin D Supplementation during Pregnancy: Double Blind, Randomized Clinical Trial of Safety and Effectiveness (2011, result): “Interestingly, this value is virtually identical to the value obtained by Heaney and colleagues with respect to the equilibration of intestinal calcium absorption.((98)) This increased level of circulating 25(OH)D in the pregnant woman also appears to reduce circulating PTH, especially in black subj”
Evaluation, treatment, and prevention of vitamin D deficiency: an Endocrine Society clinical practice guideline. (2011, background): “When postmenopausal women who had an average blood level of 25(OH)D of 20 ng/ml increased their level to 32 ng/ml, they increased the efficiency of intestinal calcium absorption by 45–65% (17).”
