In the Women's Health Initiative clinical trial (described above), vitamin D3 and calcium supplements had no effect on rates of colorectal cancer. Feb. 18, 2019. Studies have also assessed the value of vitamin D supplementation for managing diabetes, and they have found that the vitamin offers limited benefits. A reverse J-shaped association between serum 25-hydroxyvitamin D and cardiovascular disease mortality: The CopD study. Picciano MF. 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]. 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]. Pediatrics 2008;122:1142-52. Am J Clin Nutr 2019;110:1043-4. "As outside temperatures increase, the apparent survival benefit of potassium also increases.". Laboratory and animal studies suggest that vitamin D might inhibit carcinogenesis and slow tumor progression by, for example, promoting cell differentiation and inhibiting metastasis. [, Manson JE, Cook NR, Lee I-M, Christen W, Bassuk S, Mora S, et al. [, Simon AE, Ahrens KA. Rockville, MD: Agency for Healthcare Research and Quality, 2009. 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]. Among the 198 participants who died (41 deaths were due to prostate cancer), 25(OH)D levels were not associated with risk of death from prostate cancer or any cause [114]. 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).

[, Taylor CL, Rosen CJ, Dwyer JT. In addition to discomfort, you may also experience dizziness, fatigue, muscle cramps, nausea, heavy sweating, headache and rapid heartbeat. 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]. Circulating 25-hydroxyvitamin D concentration and risk of breast, prostate, and colorectal cancers: The Melbourne Collaborative Cohort Study. Individuals taking these and other medications on a regular basis should discuss their vitamin D intakes and status with their health care providers.

The results showed an association between 25(OH)D levels lower than 30 nmol/L (12 ng/mL) and a 31% higher colorectal cancer risk. Dietary supplements Arch Intern Med 2007;167:893-902. One study, for example, tested 25(OH)D levels in 1,092 women in Finland an average of 9 years before their MS diagnosis and compared their outcomes with those of 2,123 similar women who did not develop MS [139]. Hypercalcemia, in turn, can lead to nausea, vomiting, muscle weakness, neuropsychiatric disturbances, pain, loss of appetite, dehydration, polyuria, excessive thirst, and kidney stones. [, Marrie RA, Beck CA. A systematic review and meta-analysis of 14 observational studies that included a total of 31,424 adults (mean age ranging from 27.5 to 77 years) found an association between deficient or low levels of 25(OH)D and depression [130].

However, some groups particularly people who are obese, who have dark skin and who are older than age 65 may have lower levels of vitamin D due to their diets, little sun exposure or other factors. Silva MC, Furlanetto TW. [. In a study published in the journal Clinical Science in 2015, researchers from Penn State University found that when older adults and the elderly were exposed to heat, they were less able to increase blood flow than younger adults. It's involved in more than 600 reactions, including energy metabolism and protein synthesis. Although UVB exposure can produce vitamin D in infants, the American Academy of Pediatrics (AAP) advises parents to keep infants younger than 6 months out of direct sunlight, dress them in protective clothing and hats, and apply sunscreen on small areas of exposed skin when sun exposure is unavoidable [59]. Role of vitamin D in atherosclerosis. One nmol/L is equal to 0.4 ng/mL, and 1 ng/mL is equal to 2.5 nmol/L.

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]. However, the supplementation had no significant effects on fasting blood glucose, hemoglobin A1c, or fasting insulin levels. "They can also decrease sweating, which leads to a decrease in heat loss." Observational studies and clinical trials provide mixed evidence on whether vitamin D intakes or serum levels affect cancer incidence, progression, or mortality risk. 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]. For men with prostate cancer, whether vitamin D supplementation lengthens cancer-related survival is not clear. The factors that affect UV radiation exposure, individual responsiveness, and uncertainties about the amount of sun exposure needed to maintain adequate vitamin D levels make it difficult to provide guidelines on how much sun exposure is required for sufficient vitamin D synthesis [15,28]. Diets low in vitamin D are more common in people who have milk allergy or lactose intolerance and those who consume an ovo-vegetarian or vegan diet [1].

The United States mandates the fortification of infant formula with 12.5 mcg/100 kcal (40100 IU) vitamin D; 12 mcg/100 kcal (4080 IU) is the required amount in Canada [1]. These medications can reduce calcium absorption and impair vitamin D metabolism [171-173]. Because vitamin D is fat soluble, its absorption depends on the guts ability to absorb dietary fat [4]. Vitamin D supplements and muscle function One meta-analysis of 20 clinical trials compared the effects of 0.5 mcg (20 IU)/day to 1,250 mcg (50,000 IU)/week vitamin D supplementation for 26 months with those of placebo on glycemic control in 2,703 adults from around the world who had diabetes [143].

The largest clinical trial, VITAL, to investigate the effects of vitamin D supplementation on the primary prevention of cancer in the general population gave 50 mcg (2,000 IU)/day vitamin D3 supplements with or without 1,000 mg/day marine omega-3 fatty acids or a placebo for a median of 5.3 years [93].
