The amount of increase varies, for example, by baseline serum levels and duration of supplementation. Bone health also depends on support from the surrounding muscles to assist with balance and postural sway and thereby reduce the risk of falling. In contrast to 25(OH)D, circulating 1,25(OH)2D is generally not a good indicator of vitamin D status because it has a short half-life measured in hours, and serum levels are tightly regulated by parathyroid hormone, calcium, and phosphate [1]. Vitamin D plays a role in glucose metabolism. The USPSTF stated that, due to insufficient evidence, it was unable to assess the balance of benefits and harms of supplemental vitamin D to prevent cancer [117]. UVB radiation does not penetrate glass, so exposure to sunshine indoors through a window does not produce vitamin D [29]. CMAJ 2007;177:161-6.

In this procedure, part of the upper small intestine, where vitamin D is absorbed, is bypassed, and vitamin D that is mobilized into the bloodstream from fat stores might not raise 25(OH)D to adequate levels over time [67,68].

Vitamin D alone did not significantly affect the development of new serrated polyps, but the combination of vitamin D with calcium increased the risk almost fourfold.

Vitamin D has other roles in the body, including reduction of inflammation as well as modulation of such processes as cell growth, neuromuscular and immune function, and glucose metabolism [1-3].

[, Logan VF, Gray AR, Peddie MC, Harper MJ, Houghton LA. The combination of these diuretics with vitamin D supplements (which increase intestinal calcium absorption) might lead to hypercalcemia, especially among older adults and individuals with compromised renal function or hyperparathyroidism [167,175,176]. [, Caan B, Neuhouser M, Aragaki A, Lewis CB, Jackson R, LeBoff MS, et al. Curr Opin Gastroenterol 2008;24:176-83. 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. In addition, the Food and Drug Administration (FDA) has approved UV-treated mushroom powder as a food additive for use as a source of vitamin D2 in food products [18]. [, Marrie RA, Beck CA. It concluded "with moderate certainty" that vitamin D supplementation does not reduce the numbers of falls or injuries, such as fractures, resulting from falls [78,79].

Because vitamin D is fat soluble, its absorption depends on the gut’s ability to absorb dietary fat [4]. In the NHANES 2001–2006 survey, 25(OH)D deficiency (less than 25 nmol/L [10 ng/mL]) was more than twice as common among children and adults who reported oral steroid use (11%) than in nonusers (5%) [174].

However, frequent use of tanning beds, which provide artificial UV radiation, can lead to 25(OH)D levels well above 375–500 nmol/L (150–200 ng/mL) [158-160]. Vitamin D supplementation reduced cancer mortality rates by 13%, and most of the benefit occurred with daily supplementation. Among postmenopausal women and older men, many clinical trials have shown that supplements of both vitamin D and calcium result in small increases in bone mineral density throughout the skeleton [1,75]. In one meta-analysis of 46 clinical trials that included 4,541 participants, vitamin D supplements (typically 40 mcg [1,600 IU]/day or less) for a minimum of 4 weeks had no significant effects on systolic or diastolic blood pressure [127].

Vitamin D: moving forward to address emerging science. In fact, 2013–2016 NHANES data showed that 92% of men, more than 97% of women, and 94% of people aged 1 year and older ingested less than the EAR of 10 mcg (400 IU) of vitamin D from food and beverages [41]. The geographical distribution of MS around the world is unequal. [, Davis CD, Dwyer JT. In fact, Black Americans might have a greater risk than White Americans of falls and fractures with daily vitamin D intakes of 50 mcg (2,000 IU) or more [14]. In the most recent meta-analysis, 10 randomized clinical trials (including the Vitamin D and Omega-3 Trial [VITAL] trial described below) that included 6,537 cancer cases provided 10 to 50 mcg (400 to 2,000 IU) vitamin D3 daily (six trials) or 500 mcg (20,000 IU)/week to 12,500 mcg (500,000 IU)/year boluses of vitamin D3 (four trials) [91]. Some people with MS eventually lose the ability to write, speak, or walk. Obesity does not affect the skin’s capacity to synthesize vitamin D. However, greater amounts of subcutaneous fat sequester more of the vitamin [1]. Fortified foods provide most of the vitamin D in American diets [1,22]. Vitamin D status in the United States remained stable in the decade between 2003–2004 and 2013–2014. An animal's diet affects the amount of vitamin D in its tissues. Am J Clin Nutr 2019;110:1119-30. The FNB established ULs for vitamin D in 2010 (Table 4) [1]. As a result, a finding can be falsely low or falsely high, depending on the assay used and the laboratory. In contrast, a meta-analysis of 6 trials in 49,282 older adults found that daily vitamin D (10 or 20 mcg [400 IU or 800 IU]/day) and calcium (800 or 1,200 mg/day) supplementation for a mean of 5.9 years reduced the risk of any fracture by 6% and of hip fracture by 16% [82]. 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].

Over time, bone density can decline, and osteoporosis can eventually develop [72]. Overall, clinical trials show that vitamin D supplementation does not reduce CVD risk, even for people with low 25(OH)D status (below 20 nmol/L [12 ng/mL]) at baseline [93,124].

In practice, however, people usually do not apply sufficient amounts of sunscreen, cover all sun-exposed skin, or reapply sunscreen regularly. Osteoporosis is, in part, a long-term effect of calcium and/or vitamin D insufficiency, in contrast to rickets and osteomalacia, which result from vitamin D deficiency. Clinical trial evidence provides some support for the observational findings. Tolerable Upper Intake Level (UL): Maximum daily intake unlikely to cause adverse health effects. However, 18% were at risk of inadequacy (levels of 30–49 nmol/L [12–19.6 ng/mL]), and 5% were at risk of deficiency (levels below 30 nmol/L [12 ng/mL]).

No studies have evaluated whether vitamin D supplements may benefit individuals under medical care for clinical depression who have low or deficient 25(OH)D levels and are taking antidepressant medication. However, women with vitamin D intakes higher than 15 mcg (600 IU)/day at the start of the trial and who received the supplements experienced a 28% increased risk of invasive (but not in situ) breast cancer. The data on supplemental vitamin D and cholesterol levels are mixed, as shown in one meta-analysis of 41 clinical trials in a total of 3,434 participants (mean age 55 years). 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]. An analysis of NHANES 2011–2014 data on serum 25(OH)D levels found that most people in the United States aged 1 year and older had sufficient vitamin D intakes according to the FNB thresholds [44].
