Re: Vitamin D levels, Calcium Found to Cut Fracture, Cancer Risk

[Guest guest]

Its not a matter of how much vitamin D supplementation one takes, the key is to have adequate vitamin D levels in your blood, so taking the amount of vitamin D suppementation that gets you there is the key, so I recommend visiting a bone expert in order to do a blood test to check your blood vitamin d levels and then the doctor can advise on whether your blood levels are adequate and if not how much supplementation to take to try to get your blood levels to the right level.LevelsBone Guidelines: (Vitamin D Guidelines) Evaluation, Treatment, and Prevention of Vitamin D Deficiency: an Endocrine Society Clinical Practice Guideline(Vitamin D Guidelines) Evaluation, Treatment, and Prevention of ...www.natap.org/2011/HIV/060911_02.htmJun 6, 2011 – The Task Force also suggested the measurement of serum 25-hydroxyvitamin D level by a reliable assay as the initial diagnostic test in patients"recommend.....measurement of serum 25-hydroxyvitamin D level by a reliable assay as the initial diagnostic test in patients at risk for deficiency......Vitamin D deficiency is defined as a 25(OH)D below 20 ng/ml (50 nmol/liter).........sufficiency as a 25(OH)D of 30 -100 ng/ml (3)"Suggested 25(OH)D levels

Vitamin D deficiency in children and adults is a clinical syndrome caused by a low circulating level of 25(OH)D (3, 10, 25, 47, 50). The blood level of 25(OH)D that is defined as vitamin D deficiency remains somewhat controversial. A provocative study in adults who received 50,000 IU of vitamin D2 once a week for 8 wk along with calcium supplementation demonstrated a significant reduction in their PTH levels

when their 25(OH)D was below 20 ng/ml (16). Several, but not all, studies have reported that PTH levels are inversely associated with 25(OH)D and begin to plateau in adults who have blood levels of 25(OH)D between 30 and 40 ng/ml (20 -22, 60); these findings are consistent with

the threshold for hip and nonvertebral fracture prevention from a recent meta-analysis of double-blind randomized controlled trials (RCT) with oral vitamin D (56). 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). Thus, based on these and other studies, it has been suggested that vitamin D deficiency be defined as a 25(OH)D below 20 ng/ml, insufficiency as a 25(OH)D of 21-29 ng/ml, and sufficiency as a 25(OH)D of 30 -100 ng/ml (3).
