However, the evidence on the impact of vitamin D and calcium supplements on fractures in community-dwelling individuals is inconsistent. [, McDuffie JR, Calis KA, Booth SL, Uwaifo GI, Yanovski JA. PMID: 31504098 [, Okereke OI, Reynolds III CF, Mischoulon D, Chang G, Vyas CM, Cook NR, et al. These differences are a result of an incomplete understanding of the biology and clinical implications of vitamin D, different purposes for the guidelines (e.g., for public health in a healthy population or for clinical practice), and/or the use in some guidelines of observational studies in addition to randomized clinical trials to establish recommendations [9,15].

Absorption occurs by simple passive diffusion and by a mechanism that involves intestinal membrane carrier proteins [4]. Practitioner 1984;228:312-3. Most participants had minimal or mild depression, had a low mean baseline 25(OH) level of 33.8 nmol/L (13.5 ng/mL), and were not taking antidepressants. There are also other websites with similar truths. J Clin Endorcinol Metab 2015;100:2339-46. It may help prevent depression, inflammatory disease, and heart disorders. The incidence rate of rickets in the infants and children (younger than 7) seen by 2,325 pediatricians throughout Canada was 2.9 per 100,000 in 20022004, and almost all patients with rickets had been breastfed [49]. In contrast, the United Kingdom government recommends intakes of 10 mcg (400 IU)/day for its citizens aged 4 years and older [16]. However, the results did show an increased risk of pancreatic cancer with 25(OH)D levels of 100 nmol/L (40 ng/mL) or above [107]. [, Pathak K, Soares MJ, Calton EK, Zhao Y, Hallett J. Vitamin D supplementation and body weight status: A systematic review and meta-analysis of randomized controlled trials. We encourage you to talk to your health care providers (doctor, registered dietitian, pharmacist, etc.) Vitamin D helps you absorb calcium and phosphate from food. The FNB committee also noted that serum concentrations greater than 125 nmol/L (50 ng/mL) can be associated with adverse effects [1] (Table 1). 19.98. doi: 10.3390/nu10040493. In a 2015 study, Dutch researchers completed a meta-analysis of three intervention studies investigating the effects of vitamin D supplementation on serum testosterone concentrations in vitamin D-deficient subjects.

It is also present in some foods, which should be a part of your diet to maintain adequate vitamin D levels in your body. Levels of 75 to less than 87.5 nmol/L (30 to less than 35 ng/mL) and 87.5 to less than 100 nmol/L (35 to less than 40 ng/mL) were associated with a 19% and 27% lower risk, respectively. Their skin probably synthesizes some vitamin D, even with typically applied sunscreen amounts [1,28]. No. Homebound individuals; people who wear long robes, dresses, or head coverings for religious reasons; and people with occupations that limit sun exposure are among the groups that are unlikely to obtain adequate amounts of vitamin D from sunlight [62]. People with obesity or who have undergone gastric bypass surgery However, clinical trials do not support a cause-and-effect relationship between vitamin D and weight loss.

[, Han J, Guo X, Yu X, Liu S, Cui X, Zhang B, Liang H. 25-hydroxyvitamin D and total cancer incidence and mortality: A meta-analysis of prospective cohort studies. One reason is that sun exposure affects vitamin D status, so serum 25(OH)D levels are usually higher than would be predicted on the basis of vitamin D dietary intakes alone [1]. Pediatrics 2008;122:1142-52. Rickets occurred mainly in Black children who were breastfed longer, were born with low birthweight, weighed less, and were shorter than other children. Association of vitamin D status with arterial blood pressure and hypertension risk: A mendelian randomisation study. Toxicity of vitamin D leads to hypercalcemia and imbalance in the regulation of bone metabolism; the resultant hypercalcemia leads to clinical manifestations and symptoms of toxicity. Picciano MF. 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]). In contrast, another meta-analysis of 30 clinical trials in 4,744 participants (mean age 54.5 years) that administered 5 mcg (200 IU) to 300 mcg (12,000 IU)/day vitamin D3 for a mean of 5.6 months showed that more than 20 mcg (800 IU)/day significantly reduced systolic and diastolic blood pressure in normal-weight participants who had hypertension [128]. Overall, clinical trials did not find that vitamin D supplements helped prevent or treat depressive symptoms or mild depression, especially in middle-aged to older adults who were not taking prescription antidepressants. Individuals with obesity who have undergone gastric bypass surgery can also become vitamin D deficient. In addition, studies provided different amounts of nutrients and used different dosing schedules. These values, which vary by age and sex, include: An FNB committee established RDAs for vitamin D to indicate daily intakes sufficient to maintain bone health and normal calcium metabolism in healthy people.

Vitamin D supplementation has no effect on insulin sensitivity or secretion in vitamin D-deficient, overweight or obese adults: A randomized placebo-controlled trial. J Womens Health 2013:22,915-29. 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]. Some people are potentially at risk of inadequacy at 30 to 50 nmol/L (1220 ng/mL). Studies of the effects of vitamin D supplements on hypertension have also had mixed findings. In the most recent meta-analysis, 10 randomized clinical trials (including the 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]. DRI is the general term for a set of reference values used for planning and assessing nutrient intakes of healthy people. Am J Clin Nutr 2004;80:1710S-6S. However, other, shorter (from 24 weeks to 5 years) clinical trials of vitamin D supplementation alone or with calcium in adults found greater risks of hypercalcemia and hypercalciuria, but not of kidney stones [162,163].

Bioavailability of vitamin D2 and D3 in healthy volunteers, a randomised placebo-controlled trial. Most participants were vitamin D sufficient; at baseline, only 2.4% had serum 25(OH)D levels less than 30 nmol/L (12 ng/mL), and 12.9% less than 50 nmol/L (20 ng/mL). 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]. Vitamin D for the management of multiple sclerosis (review). People with obesity might need greater intakes of vitamin D to achieve 25(OH)D levels similar to those of people with normal weight [1,64,65]. In addition, 26% of participants aged 25 years and 14% of those aged 611 years took supplements; rates increased with age from 10% of those aged 1219 years to 49% of men and 59% of women aged 60 and older. Few foods naturally contain vitamin D. The flesh of fatty fish (such as trout, salmon, tuna, and mackerel) and fish liver oils are among the best sources [17,1].

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 Vitamin D might also have anti-inflammatory, immunomodulatory, proapoptotic, and antiangiogenic effects [1,87]. Estimated Average Requirement (EAR): Average daily level of intake estimated to meet the requirements of 50% of healthy individuals; usually used to assess the nutrient intakes of groups of people and to plan nutritionally adequate diets for them; can also be used to assess the nutrient intakes of individuals. In the NHANES 20012006 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]. This can improve musculoskeletal health by naturally slowing aging of the skeletal structure and reducing the rate of fractures and falls in older adults that are over 65. Studies show that 25(OH)D appears to be approximately five times more potent than the parent vitamin for raising serum 25(OH)D concentrations [17,20,21]. Total vitamin D intakes were three times higher with supplement use than with diet alone; the mean intake from foods and beverages alone for individuals aged 2 and older was 4.8 mcg (192 IU) but increased to 19.9 mcg (796 IU) when dietary supplements were included.

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]. Bone mineral density, bone mass, and fracture risk are correlated with serum 25(OH)D levels in White Americans and Mexican Americans, but not in Black Americans [14,83]. Drug-vitamin D interactions: A systematic review of the literature. The groups showed no significant differences in measures of muscle strength or performance [85]. Another study that compared 200 male smokers in Finland with pancreatic cancer to 400 matched controls found that participants in the highest quintile of 25(OH)D levels (more than 65.5 nmol/L [26.2 ng/mL]) had a threefold greater risk of developing pancreatic cancer over 16.7 years than those in the lowest quintile (less than 32 nmol/L [12.8 ng/mL]) [106]. Again, the pattern was similar for the risk of inadequacy. [, Taylor CL, Thomas PR, Aloia JF, Millard PS. [, Yin L, Ordonez-Mena JM, Chen T, Schottker B, Arndt V, Brenner H. Circulating 25-hydroxyvitamin D serum concentration and total cancer incidence and mortality: A systematic review and meta-analysis. Rates of breast, prostate, and colorectal cancer did not differ significantly between the vitamin D and placebo groups. Another meta-analysis of genetic studies in 146,581 participants (primarily adults) found that a low vitamin D status increased blood pressure and hypertension risk in people with genetic variants associated with low endogenous production of 25(OH)D [129]. Vitamin D, Volume 1: Biochemistry, Physiology and Diagnostics, Fourth Edition. 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]. Several studies published in 2014 suggested that high levels of 25(OH)D might increase the risk of prostate cancer. Vitamin D is essential for bone strength and may support the immune system and other functions. In contrast to water-soluble vitamins, the body has no easy way of getting rid of fat-soluble vitamins. Includes a variety of protein foods such as lean meats; poultry; eggs; seafood; beans, peas, and lentils; nuts and seeds; and soy products. One nmol/L is equal to 0.4 ng/mL, and 1 ng/mL is equal to 2.5 nmol/L. I produce this site out of my passionate desire to inform as many people as possible about the nature of our body's need for the proper nutrients in adequate amounts. 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]. Nutrient composition of human milk. [, Davis CD, Dwyer JT. The use of sunscreen also limits vitamin D synthesis from sunlight. Some observational studies show associations between low serum levels of 25(OH)D and increased risks of cancer incidence and death. However, a post hoc analysis showed a 62% lower incidence of diabetes among participants with low baseline serum 25(OH)D levels (less than 30 nmol/L [12 ng/mL]) who took the vitamin D supplement than among those who took the placebo [145,150]. The Endocrine Society states, for example, that to maintain serum 25(OH)D levels above 75 nmol/L (30 ng/mL), adults might need at least 37.5 to 50 mcg (1,5002,000 IU)/day of supplemental vitamin D, and children and adolescents might need at least 25 mcg (1,000 IU)/day [11]. 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% [81]. It helps the bones absorb calcium, supports the immune system and may aid strength gain and fat loss. Thiazide diuretics (e.g., Hygroton, Lozol, and Microzide) decrease urinary calcium excretion. People can develop vitamin D deficiency when usual intakes are lower over time than recommended levels, exposure to sunlight is limited, the kidneys cannot convert 25(OH)D to its active form, or absorption of vitamin D from the digestive tract is inadequate.
