The actual hazard ratio for vitamin D as compared with placebo was 0.88 (95% confidence interval, 0.751.04; P=0.12). Serum 25(OH)D is considered to be the best marker for assessing vitamin D status, and reliably reflects the free fractions of the vitamin D metabolites, despite the fact that, in theory, the bioavailable fractions may be more clinically informative [9, 10].

As an example, in liver transplantation recipients (a group of patients with very low vitamin D levels), osteoporosis has a high prevalence, with a large decline in bone mineral density in the first year after transplantation. Recent large observational data have suggested that ~40% of Europeans are vitamin D deficient, and 13% are severely deficient [2]. Amrein K, Martucci G, McNally JD.

Crowe FL, Jolly K, MacArthur C, Manaseki-Holland S, Gittoes N, Hewison M, et al. Vitamin D levels of <30nmol/L (or 12ng/ml) should likely be prevented with a public health approach [17]. Because more often than not, trials have included non-deficient individuals, it is not surprising that interventional trials have usually not been able to find a benefit of vitamin D supplementation on clinical outcomes. https://doi.org/10.1210/jc.2015-2175, Martineau AR, Jolliffe DA, Hooper RL, Greenberg L, Aloia JF, Bergman P, et al. https://doi.org/10.1371/journal.pone.0180483.

Three major adverse pregnancy outcomes appear to improve with vitamin D supplementation: a 60% reduction in preeclampsia, a 50% reduction in gestational diabetes, and a 40% reduction in preterm delivery [84]. On the other hand, even a very small effect may be useful for a substance with such an excellent safety profile and low cost, especially when considering a public health approach. Aloia JF, Patel M, DiMaano R, Li-Ng M, Talwar SA, Mikhail M, et al. 1992;326:11737.

It is a fat-soluble vitamin that has long been known to help the body absorb and retain calcium and phosphorus; both are critical for building bone. There is no convincing evidence that daily intakes of up to 125g (5000IU) elicit severe adverse effects [39]. Natural sources of vitamin D: Dietary: Few foods, other than fatty fish, naturally contain moderately high amounts of vitamin D, and these foods are often not readily accessible in low- and middle-income countries (LMICs). The in vivo supplementation of a high dose of cholecalciferol (400.000IU as a single bolus) in the early stage of sepsis and septic shock has been shown able to safely and rapidly increase the level of vitamin D, as well as the circulating level of cathelicidin, a vitamin D-dependent endogenous anti-microbial and endotoxin-binding peptide largely found in human neutrophils [73].

Investigating cancer incidence following vitamin D plus calcium supplementation, Lappe et al. Vitamin D deficiency when the level of vitamin D in your body is too low can cause your bones to become thin, brittle or misshapen. The placenta can convert 25(OH)D to the active form 1,25(OH)2D, similarly to the kidneys; therefore, more basic research should shed light in the future on the specific vitamin D metabolism during pregnancy [85].
