- Chronic Kidney Disease decreases Vitamin D in 4 ways – Nov 2017
- Half as much chronic kidney disease infection if supplement with Vitamin D – 2018
- 2.4 times more likely to die if have Chronic Kidney Disease and low vitamin D - Sept 2016
- 4X more Chronic Kidney disease patients are now using vitamin D – March 2014
- Poor kidneys rarely get enough or the right form of vitamin D – Feb 2019
Overview Kidney and vitamin D contains the following summary
- FACT: The Kidneys are not the primary way to activate vitamin D, the tissues are
- FACT: When the Kidney has problems, there is less active vitamin D (Calcitriol) for the body
- FACT: When the Kidney has problems, there is increased death due to many factors - many of which are associated with lack of Calcitriol
- FACT: There are many on-going intervention clinical trials trying to determine how much of what kind of vitamin D is needed to treat the problem
- FACT: One Randomized Controlled Trial has proven that Vitamin D treats CKD
- FACT: 38% of seniors have Chronic Kidney Disease and most are unaware of it CDC statistics 2020
- FACT: Taking extra Vitamin D, in various forms, does not cause health problems - even if poor kidney
- Suggestion: Increase vitamin D getting into body now - and increase co-factors so that the vitamin D can be better used
Sun, UV lamp, Vitamin D supplement - probably > 5,000 IU,
Calcitriol - which bypasses the need for the kidney to activate vitamin D
Problems with Calcitriol however: typically only lasts for a few hours, also, possible complications
Update: Pre-cursor of active vitamin D made from plants is better than calcitriol – Sept 2012

Background: Vitamin D (VitD) deficiency is associated with several diseases such as multiple sclerosis, rheumatoid arthritis, respiratory infection, and so forth. In the field of transplantation (kidney transplantation), some studies reported that patients with VitD deficiency are of increased chance of acute rejection, but other studies did not show such a chance. On the other hand, since VitD is a modulatory factor and can reduce the inflammatory response, understanding the exact role of it in transplantation may contribute to tolerance condition in these patients.
Methods: The electronic databases, including PubMed, Scopus, Embase, ProQuest, Web of Science, and Google Scholar, were searched for eligible studies. In general, 14 studies with a total of 4770 patients were included in this meta-analysis. Regarding the methodological heterogeneity, we selected a random-effects combination model. Moreover, OR was chosen as an effect size for this study.
Results: After the combination of 14 studies, we showed that patients in the VitD-deficient group had an 82% increased chance of acute rejection compared with patients in the VitD-sufficient group, and this effect was significant (OR 1.82; 95% confidence interval [CI] [1.29, 2.56]; I2 = 52.3%). This result was significant, and, regarding the narrow CI, it can be a conclusive result. Study quality and gender variables were the main sources of inconsistent results in the primary studies. Moreover, using meta-regression, we showed that VitD deficiency (independent from the estimated glomerular filtration rate (eGFR) of patients) increased the chance of acute rejection.
Conclusion: The normal VitD status of patients a few days before and after transplantation can reduce the chance of acute rejection.
