Ann Intern Med 2014;160:558-64. 6.Mushrooms. Several studies published in 2014 suggested that high levels of 25(OH)D might increase the risk of prostate cancer. People who avoid all animal-sourced products can contact dietary supplement manufacturers to ask about their sourcing and processing techniques. A few studies have examined the effect of vitamin D supplementation on specific cancers. However, because research has been conducted on vitamin D and numerous health outcomes, this section focuses on seven diseases, conditions, and interventions in which vitamin D might be involved: bone health and osteoporosis, cancer, cardiovascular disease (CVD), depression, multiple sclerosis (MS), type 2 diabetes, and weight loss.

Many genes encoding proteins that regulate cell proliferation, differentiation, and apoptosis are modulated in part by vitamin D. Many tissues have vitamin D receptors, and some convert 25(OH)D to 1,25(OH)2D. It helps the bones absorb calcium, supports the immune system and may aid strength gain and fat loss. Recommended Dietary Allowance (RDA): Average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%98%) healthy individuals; often used to plan nutritionally adequate diets for individuals. Many epidemiological and genetic studies have shown an association between MS and low 25(OH)D levels before and after the disease begins [137]. June 2014. 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).

Vitamin D (also referred to as "calciferol") is a fat-soluble vitamin that is naturally present in a few foods, added to others, and available as a dietary supplement. British Journal of Cancer 2014;111:976-80. Many other countries around the world and some professional societies have somewhat different guidelines for vitamin D intakes [15]. Salmon. Vitamin D belongs to the family of fat-soluble vitamins, which include vitamins A, D, E and K. These vitamins are absorbed well with fat and are stored in the liver and fatty tissues. Hossein-nezhad A, Holick MF. Moreover, the effects did not vary by baseline serum 25(OH)D levels or whether participants took the trials omega-3 supplement in addition to vitamin D. However, another clinical trial designed to investigate bone fracture risk found that 800 IU/day vitamin D3 (with or without calcium) or a placebo in 5,292 adults aged 70 years and older for a median of 6.2 years offered protection from cardiac failure, but not myocardial infarction or stroke [125].

Despite increasing serum 25(OH)D levels to an average of more than 80 nmol/L (32 ng/ml), vitamin D supplementation did not affect lower-extremity power, strength, or lean mass. Greater amounts of the pigment melanin in the epidermal layer of the skin result in darker skin and reduce the skins ability to produce vitamin D from sunlight [1]. [, Earthman CP, Beckman LM, Masodkar K, Sibley SD. 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. [, Shea MK, Fielding RA, Dawson-Hughes B. Your doctor may recommend a vitamin D tablet for you. It is also found in some animal foods and supplements. Vitamin D supplementation did not lower the risk of total fractures, hip fractures, or nonvertebral fractures as compared with placebo. DRI is the general term for a set of reference values used for planning and assessing nutrient intakes of healthy people. Curr Opin Endocrinol Diabetes 2002;9:87-98. Vitamin D had no significant effects on glucose homeostasis, insulin secretion or resistance, or hemoglobin A1c levels (a measure of average blood sugar levels over the previous 23 months), irrespective of the study population, vitamin D dose, or trial quality. Vitamin D2 is from plant sources. 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]. Vitamin D is important for bone and muscle strength and immune function. J Nutr 2018;148:712-20. For example, three meta-analyses of clinical trial evidence found that vitamin D supplementation does not affect cancer incidence but does significantly reduce total cancer mortality rates by 1213% [90-92]. Vitamin D, calcium, or combined supplementation for the primary prevention of fractures in community-dwelling adults. It is also produced endogenously when ultraviolet (UV) rays from sunlight strike the skin and trigger vitamin D synthesis. Borel P, Caillaud D, Cano NJ. After reviewing data on vitamin D needs, an expert committee of the Food and Nutrition Board (FNB) at the National Academies of Sciences, Engineering, and Medicine (NASEM) concluded that people are at risk of vitamin D deficiency at serum 25(OH)D concentrations less than 30 nmol/L (12 ng/mL; see Table 1 for definitions of "deficiency" and "inadequacy") [1].

LeBoff MS, Chou SH, Ratliff KA, Cook NR, Khurana B, Kim E, et al. 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].

Some observational studies support an inverse association between 25(OH)D levels and breast cancer risk and mortality, but others do not [94-97]. Some observational studies show associations between low serum levels of 25(OH)D and increased risks of cancer incidence and death. [, Pathak K, Soares MJ, Calton EK, Zhao Y, Hallett J.

One study comparing 738 men who developed pancreatic cancer to 738 matched controls found no relationship between serum 25(OH)D levels and risk of pancreatic cancer [105]. It may help prevent depression, inflammatory disease, and heart disorders. Osteoporosis is most often associated with inadequate calcium intakes, but insufficient vitamin D intakes contribute to osteoporosis by reducing calcium absorption [1].

The investigators randomly assigned participants to receive either a bolus oral dose of 2,500 mcg (100,000 IU) vitamin D3 followed by 100 mcg (4,000 IU)/day or a placebo for 16 weeks. Proportions at risk of deficiency were lowest among children aged 15 years (0.5%), peaked at 7.6% in adults aged 2039 years, and fell to 2.9% among adults aged 60 years and older; patterns were similar for risks of inadequacy. Two earlier prospective studies of similar designone in the United States with 444 non-Hispanic White individuals [140] and the other with 576 individuals in northern Sweden [141]found that levels of 25(OH)D greater than 99.1 nmol/L (39.6 ng/mL) and at least 75 nmol/L (30 ng/mL), respectively, were associated with a 6162% lower risk of MS. No clinical trials have examined whether vitamin D supplementation can prevent the onset of MS, but several have investigated whether supplemental vitamin D can help manage the disease.

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. A dose-response analysis found that each 20 nmol/L [8 ng/mL] increase in 25(OH)D was associated with a 9% lower risk of both all-cause and prostate cancer-specific mortality.

This uneven distribution has led to speculation that lower vitamin D levels in people who have less sunlight exposure might predispose them to the disease [137]. 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.

Cholecalciferol or 25-hydroxycholecalciferol supplementation does not affect muscle strength and physical performance in prefrail and frail older adults. 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]. Your body also makes vitamin D when direct sunlight converts a chemical in your skin into an active form of the vitamin (calciferol).
