Some studies have used dietary supplements containing the 25(OH)D3 form of vitamin D. Per equivalent microgram dose, 25(OH)D3 is three to five times as potent as vitamin D3 [37,38]. However, comparing vitamin D intakes to serum 25(OH)D levels is problematic. Vitamin D deficiency or insufficiency did not increase the risk of prostate cancer, and higher 25(OH)D concentrations were not associated with a lower risk. The second trial included 155 adults aged 6080 years who had clinically relevant depressive symptoms, no major depressive disorder, and serum 25(OH)D levels less than 50 to 70 nmol/L (20 to 28 ng/mL) depending on the season; in addition, they were not taking antidepressants [133,134].

Ann Intern Med 1996;125:961-8. The international Vitamin D Standardization Program has developed procedures for standardizing the laboratory measurement of 25(OH)D to improve clinical and public health practice [5,7-10].

Obesity does not affect the skins capacity to synthesize vitamin D. However, greater amounts of subcutaneous fat sequester more of the vitamin [1]. Twitter. Am J Clin Nutr 2019;110:150-7. However, a meta-analysis of 7 cohort studies that included 7,808 men with prostate cancer found higher 25(OH)D levels to be significantly associated with lower mortality rates from prostate cancer or any other cause [115]. Several forms of vitamin D exist.The two major forms are vitamin D 2 or ergocalciferol, and vitamin D 3 or cholecalciferol. However, more than 20 mcg (800 IU)/day vitamin D3, when taken with calcium supplements, significantly increased blood pressure in participants with overweight and obesity.

As a result, a finding can be falsely low or falsely high, depending on the assay used and the laboratory. In addition, most steps in the metabolism and actions of vitamins D2 and D3 are identical. However, frequent use of tanning beds, which provide artificial UV radiation, can lead to 25(OH)D levels well above 375500 nmol/L (150200 ng/mL) [158-160].

Many other countries around the world and some professional societies have somewhat different guidelines for vitamin D intakes [15]. In the VITAL trial described above, 16,657 men and women 50 years of age and older with no history of depression and 1,696 with an increased risk of recurrent depression (that had not been medically treated for the past 2 years) were randomized to take 50 mcg (2,000 IU)/day vitamin D3 (with or without fish oil) or a placebo for a median of 5.3 years [135]. Even though sunlight is a major source of vitamin D for some people, the FNB based the vitamin D RDAs on the assumption that people receive minimal sun exposure [1]. Endocrine Connections 2018;7:R294-303. However, 18% were at risk of inadequacy (levels of 3049 nmol/L [1219.6 ng/mL]), and 5% were at risk of deficiency (levels below 30 nmol/L [12 ng/mL]). Having produced a solution of this blue indicator, some researchers suggest its use as an indicator for the presence of Vitamin C. Of course, as I state elsewhere on the site, it is somewhat of a disservice to discuss one nutrient alone and not discuss the vast array of nutrients required and the complex systems in That said, vitamin D is impressively toxic. In a subsequent investigation for 4.9 years after the study's end, women who had taken the vitamin D and calcium supplements (many of whom continued to take them) had an 18% lower risk of in situ (noninvasive) breast cancer [100].

Sun exposure The FNB recommended avoiding serum 25(OH)D levels above approximately 125150 nmol/L (5060 ng/mL), and it found that even lower serum levels (approximately 75120 nmol/L [3048 ng/mL]) are associated with increases in rates of all-cause mortality, risk of cancer at some sites (e.g., pancreas), risk of cardiovascular events, and number of falls and fractures among older adults. Observational studies indicate that greater body weights are associated with lower vitamin D status, and individuals with obesity frequently have marginal or deficient circulating 25(OH)D levels [151]. Another study randomized 100 community-dwelling men and women aged 60 years and older (most were White) with serum 25(OH)D levels of 50 nmol/L (20 ng/ml) or less to 800 IU vitamin D3 or placebo for 1 year [86]. UVB radiation does not penetrate glass, so exposure to sunshine indoors through a window does not produce vitamin D [27].

In addition, although 25(OH)D levels rise in response to increased vitamin D intake, the relationship is nonlinear [1]. Am J Clin Nutr 2014;100:746-55. In contrast to the observational studies, clinical trials have provided little support for the hypothesis that supplemental vitamin D reduces the risk of CVD or CVD mortality. However, a meta-analysis of 12 vitamin D supplementation trials (including 5 in which body composition measurements were primary outcomes) found that vitamin D supplements without calorie restriction did not affect body weight or fat mass when the results were compared with those of placebo [154].

Furthermore, the bone health of older Black American women does not appear to benefit from raising serum 25(OH)D levels beyond 50 nmol/L (20 ng/mL) [84]. Vitamin D for the management of multiple sclerosis (review). Observational studies suggest that adequate vitamin D levels might reduce the risk of contracting MS and, once MS is present, decrease the risk of relapse and slow the disease's progression [138]. Studies have also assessed the value of vitamin D supplementation for managing diabetes, and they have found that the vitamin offers limited benefits. Screening for vitamin D deficiency: Systematic review for the U.S. Preventive Services Task Force recommendation. Intake recommendations for vitamin D and other nutrients are provided in the Dietary Reference Intakes (DRIs) developed by expert committees of NASEM [1].

The weight-loss drug orlistat (Xenical and alli), together with a reduced-fat diet, can reduce the absorption of vitamin D from food and supplements, leading to lower 25(OH)D levels [164-167]. Circulating vitamin D and colorectal cancer risk: An international pooling project of 17 cohorts. Most people in the world meet at least some of their vitamin D needs through exposure to sunlight [1]. For example, almost all of the U.S. milk supply is voluntarily fortified with about 3 mcg/cup (120 IU), usually in the form of vitamin D3 [23]. In addition, older adults are likely to spend more time than younger people indoors, and they might have inadequate dietary intakes of the vitamin [1]. Overall, the risk of CVD events was 10% lower for each 25 nmol/L (10 ng/mL) increase in serum 25(OH)D. Another large observational study that followed 247,574 adults from Denmark for 07 years found that levels of 25(OH)D that were low (about 12.5 nmol/L [5 ng/mL]) and high (about 125 nmol/L [50 ng/mL]) were associated with a greater risk of mortality from CVD, stroke, and acute myocardial infarction [121]. Vitamin D is a pro-hormone. It means that our body converts it into a hormone. [, Durup D, Jorgensen HL, Christensen J, Tjonnland A, Olsen A, Halkjaer J, et al. In addition, high intakes of vitamin D, especially from supplements, might reduce the potency of atorvastatin (Lipitor), lovastatin (Altoprev and Mevacor), and simvastatin (FloLipid and Zocor), because these statins and vitamin D appear to compete for the same metabolizing enzyme [167-170]. Individuals who have difficulty absorbing dietary fat might therefore require vitamin D supplementation [63]. Effects of atorvastatin on vitamin D levels in patients with acute ischemic heart disease. The FNB committee that established DRIs for vitamin D found that the evidence was inadequate or too contradictory to conclude that the vitamin had any effect on a long list of potential health outcomes (e.g., on resistance to chronic diseases or functional measures), except for measures related to bone health.
