Healthy elderly French women living at home have secondary hyperparathyroidism and high bone turnover in winter. EPIDOS Study Group. Chapuy MC, Schott AM, Garnero P, Hans D, Delmas PD, Meunier PJ. J Clin Endocrinol Metab. 1996 Mar;81(3):1129-33. PMID: 8772587 These results show that vitamin D status of a French aged population in good health and living at home depends mainly on lifestyle. Like institutionalized women, old women living at home exhibit clear evidence of senile hyperparathyroidism in the winter, secondary in part to a reduced 25OHD level and associated with biological signs of increased bone turnover. The maintenance of PTH within the normal range for healthy adults by vitamin D and calcium treatment might constitute an approach for the prevention of bone loss in the entire

Vitamin D2 is much less effective than vitamin D3 in humans. Armas LA, Hollis BW, Heaney RP. J Clin Endocrinol Metab. 2004 Nov;89(11):5387-91. PMID: 15531486 Vitamin D2 potency is less than one third that of vitamin D3. Physicians resorting to use of vitamin D2 should be aware of its markedly lower potency and shorter duration of action relative to vitamin D3.

Prevalence of Vitamin D inadequacy among postmenopausal North American women receiving osteoporosis therapy. Holick MF, Siris ES, Binkley N, Beard MK, Khan A, Katzer JT, Petruschke RA, Chen E, de Papp AE. J Clin Endocrinol Metab. 2005 Jun;90(6):3215-24. Epub 2005 Mar 29. PMID: 15797954 doi:10.1210/jc.2004-2364 Conclusions: More than half of North American women receiving therapy to treat or prevent osteoporosis have vitamin D inadequacy, underscoring the need for improved physician and public education regarding optimization of vitamin D status in this population.

Association of vitamin D deficiency with heart failure and sudden cardiac death in a large cross-sectional study of patients referred for coronary angiography. Pilz S, März W, Wellnitz B, Seelhorst U, Fahrleitner-Pammer A, Dimai HP, Boehm BO, Dobnig H. J Clin Endocrinol Metab. 2008 Oct;93(10):3927-35. Epub 2008 Aug 5. PMID: 18682515 doi:10.1210/jc.2008-0784 Conclusions: Low levels of 25(OH)D and 1,25(OH)2D are associated with prevalent myocardial dysfunction, deaths due to heart failure and SCD. Interventional trials are warranted to elucidate whether vitamin D supplementation is useful for treatment and/or prevention of myocardial diseases.
