This outcome suggests that there may be a difference in vitamin d preparations when given in pharmacologic versus physiologic doses in the resultant increase in 25-ohd levels. To see the full set of research information and references for vitamin d. Some preliminary studies link low vitamin d levels with disease later in life. Practices of vitamin d recommendation in las vegas, nevada. Through these actions, vitamin d helps keep the calcium and phosphate levels in the blood normal, thereby promoting bone health. In argentinean children, a single 150,000-iu oral dose of ergocalciferol safely maintained 25-ohd levels at a mean of 18,7 ng/ml but did not improve serum pth concentrations. There appears to be less risk of cardiovascular disease and related cardiovascular complications with supplementation of 1,000 iu of vitamin d or higher serum levels of vitamin d, although studies using less have had null results. Of course, patients with chronic kidney disease are a different story because vitamin d is involved in calcium, phosphorus, pth, and bone mineral density homeostasis (Which is abnormal due to ckd). Although this strategy can be a useful methodology to force a physiologic change (And, thus, to possibly piece together a mechanism of action), these studies offered little information for lower doses, which are more realistic in terms of what individuals are likely to be able to consume within their daily diet and gain from sunlight exposure and the concentrations of ergocalciferol and cholecalciferol available in commercial supplements.
These active forms have been studied in clinical trials, finding no difference in fall prevention when compared to ergocalciferol or cholecalciferol, but an increased rate of side effects such as hypercalcemia. High dose bolus supplementation to rapidly build stores in infants Is not yet recommended as a public health strategy. Nevertheless, our study differs in that we administered vitamin d 2, and we assessed the outcome in patients who generally received vitamin d therapy for a longer period.

The vitamin d content of current en or pn solutions is inadequate for repleting a deficiency. 1,13 One expert recommends sensible sun exposure as an important adjuvant to vitamin d supplementation; such exposure, from either sunlight or ultraviolet radiation (Tanning beds), would involve 5-30 minutes to arms and legs twice weekly between the hours of 10 am and 3 pm while wearing sunscreen on the face. Of note, most dosing is in terms of international units, or iu (1 Iu is the equivalent of 25 ng of vitamin d). People who had a vitamin d blood level below 12 nanograms per milliliter had a colorectal cancer risk 31 percent higher over five years than those whose blood levels were twice as high. People with chronic kidney and liver disease are at increased risk of low active vitamin d levels because they have decreased levels of these enzymes. Governmental regulatory agencies stipulate for the food and dietary supplement industries certain health claims as allowable as statements on packaging.
This short review will explore key considerations when assessing and interpreting the measurement of vitamin d status and protocols for supplementation with vitamin d. In conclusion, our results suggest a favoring toward cholecalciferol rather than ergocalciferol supplementation with respect to the more effective improvement of vitamin d status. In the supplement world, vitamin d is a bit like a kardashian.

Apart from the flesh of fatty fish (Such as salmon, tuna and mackerel) and fish liver oils, very little foods contain vitamin d. A similar process takes place in plants and mushrooms, where uvb light leads to the formation of vitamin d2 from ergosterol, a compound found in plant oils.

Numerous observational studies suggest that optimal vitamin d status may be associated with fewer occurrences of cancer and cardiovascular disease (Such as heart attack or stroke). There is also some evidence that the vitamin may reduce the incidence of several types of cancer and type-1 and -2 diabetes. In addition to the classical effects on bone outcomes, improving vitamin d status provides extraskeletal benefits for several populations at risk for vitamin d insufficiency. Conclusions: This meta-analysis indicates that vitamin d 3 is more efficacious at raising serum 25(Oh)d concentrations than is vitamin d 2, and thus vitamin d 3 could potentially become the preferred choice for supplementation.

Objective: The objective of this article was to report a systematic review and meta-analysis of randomized controlled trials (Rcts) that have directly compared the effects of vitamin d 2 and vitamin d 3 on serum 25(Oh)d concentrations in humans. Given that both ergocalciferol and cholecalciferol undergo metabolic changes in the human body, which differ from other animals, it should make sense that a binding study in rats may not be sufficient to show equivalence.

The reasons why cholecalciferol is much more proficient than ergocalciferol at raising serum 25(Oh)d concentrations must be examined. Thus, vitamin d 2 was consistently less effective than vitamin d 3 in achieving optimal serum 25(Oh)d concentrations. Extra vitamin d offered no heart protection (Sn: 12/8/18, P.

Conglomerating the results from bischoff-ferrari, lyles, smith and mak, there does not appear to be any justification in having regular high-dose vitamin d supplements at monthly intervals, due to the risk of vitamin d toxicity, hypercalcaemia and perhaps oversaturation of vitamin d receptors on skeletal muscles, leading to a propensity to falls. In addition, melanin pigmentation of the skin absorbs beta radiation and thus it limits the ability to make vitamin d for those with darker skin. Calcifediol is then converted by the kidneys to calcitriol, the biologically active form of vitamin d. The vitamin d 2 content in mushrooms and cladina arbuscula, a lichen, increase with exposure to ultraviolet light. Both d3 and d2 precursors are transformed in the liver and kidneys into 25- hydroxyvitamin d (25(Oh)d), the non-active storage Form, and 1,25-dihydroxyvitamin d (1,25(Oh)2d).
In addition to disagreement over a target number, there is controversy over which form of vitamin d to measure, and how to measure it. The institute of medicine recommends that most adults and children consume 200 to 600 iu of vitamin d daily; however, this recommendation assumes that the individual is vitamin d sufficient initially. 1 A recent attempt to quantify the vitamin d production from sun exposure at different times of the day, at different latitudes, and in people with different amounts of skin pigmentation, found too much variation in vitamin d produced to accurately predict whether an individual would meet official recommendations of daily vitamin d needs, leading the authors to favor vitamin d supplementation.
