However, no 25(OH)D3 dietary supplements appear to be available to consumers on the U.S. market at this time [32]. 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). Thiazide diuretics (e.g., Hygroton, Lozol, and Microzide) decrease urinary calcium excretion. In the case of vitamin D, vitamin D3 can be of animal origin (from sheep lanolin), but in the last few years botanical sources of vitamin D3, Cladonia raingiferina (reindeer lichen), have become available [ 47 ].

The AAP recommends 10 mcg (400 IU)/day vitamin D supplements for exclusively and partially breastfed infants starting shortly after birth and lasting until they are weaned and consume at least 1,000 mL/day vitamin D-fortified formula or whole milk [57]. 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]. 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]. Nutr Metab Cardiovasc Dis 2016;26:663-73. Older adults J Clin Endorcinol Metab 2015;100:2339-46. Serum concentrations of 25(OH)D and health Some expert bodies and vitamin D researchers suggest, for example, that approximately 530 minutes of sun exposure, particularly between 10 a.m. and 4 p.m., either daily or at least twice a week to the face, arms, hands, and legs without sunscreen usually leads to sufficient vitamin D synthesis [13,15,28]. Vitamin D and cardiovascular disease: Controversy unresolved. Am J Clin Nutr 2019;110:1119-30. 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. Vitamin D supplementation reduced cancer mortality rates by 13%, and most of the benefit occurred with daily supplementation. Am J Med 2015;128:1167-70. Observational studies support an association between higher serum 25(OH)D levels and a lower risk of CVD incidence and mortality. 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]. In addition, most steps in the metabolism and actions of vitamins D2 and D3 are identical. [, Cashman KD, Seamans KM, Lucey AJ, Stocklin E, Weber P, Kiely M, Hill TR.

[. Am J Clin Nutr 2012;95:1350-6. Consumption of human milk alone does not ordinarily enable infants to meet vitamin D requirements, because it provides less than 0.6 to 2.0 mcg/L (25 to 78 IU/L) [1,56,57]. As mentioned, a vitamin D status test can determine whether this vitamin deficiency is at the JAMA 2018;319:1696-1704. Vitamin D and calcium: A systematic review of health outcomes. 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].

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]. 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]. [, Earthman CP, Beckman LM, Masodkar K, Sibley SD. 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].

An animal-free version of vitamin D3 sourced from lichen is also available [32].

A systematic review and meta-analysis of 15 weight-loss intervention studies that used caloric restriction, exercise, or both, but not necessarily vitamin D supplementation or other treatments, found that people who lost weight had significantly greater increases in serum 25(OH)D levels than those who maintained their weight [152].

JAMA 2018;319:1592-9. Am J Clin Nutr 2016;104:1039-51. 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]. Older people and people with dark skin are less able 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]. In another study, 10 mcg (400 IU)/day vitamin D and 1,000 mg/day calcium supplementation slightly, but significantly, reduced weight gain amounts in comparison with placebo in postmenopausal women, especially those with a baseline total calcium intake of less than 1,200 mg/day [153].

Effects of vitamin D supplementation in atorvastatin-treated patients: A new drug interaction with an unexpected consequence. That's because this group is already at risk for lower potassium levels, and that means they're also at an increased risk of heat stroke, cardiac arrhythmia and even death. 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]. In fact, vitamin D deficiency has become an increasingly common problem for many us. A prospective nested case-control study of vitamin D status and pancreatic cancer risk in male smokers. For example, a meta-analysis included 34 observational studies that followed 180,667 participants (mean age greater than 50 years) for 1.3 to more than 32 years.

But despite the importance of the sun for vitamin D synthesis, limiting skin exposure to sunlight and UV radiation from tanning beds is prudent [28]. In addition to discomfort, you may also experience dizziness, fatigue, muscle cramps, nausea, heavy sweating, headache and rapid heartbeat. "Magnesium provides a natural remedy for anxiety."

The human body produces vitamin D as a response to sun exposure. Pediatrics 2008;122:1142-52. We already mentioned electrolytes and potassium is one example. 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]. 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].

While acknowledging that signs and symptoms of toxicity are unlikely at daily intakes below 250 mcg (10,000 IU), the FNB noted that even vitamin D intakes lower than the ULs might have adverse health effects over time. But there's a specific group of people that potassium is ideal for and that's anyone taking diuretics. Another study included 2,259 healthy individuals aged 45 to 75 years who had had one or more serrated polyps (precursor lesions to colorectal cancer) that had been removed [102].
