Micronutrient Status in Adult Crohn's Disease during Clinical Remission: A Systematic Review

Adults with Crohn's disease (CD) may be at risk of micronutrient insufficiency in clinical remission through restrictive eating, malabsorption, abnormal losses or inflammation. This systematic review synthesises the literature on micronutrient insufficiency in CD in clinical remission in terms of the prevalence of low circulating micronutrient concentrations and as a comparison against a healthy control (HC). Studies were included if the population was predominantly in remission. A total of 42 studies met the inclusion criteria; 12 were rated as low quality, leaving 30 studies covering 21 micronutrients of medium/high quality that were included in the synthesis.
Vitamins D and B12 were the most frequently reported nutrients (8 and 11); there were few eligible studies for the remaining micronutrients.
The prevalence studies were consistent in reporting individuals with low

    • A,
    • B6,
    • B12
    • C,
    • β-carotene,
    • D,
  • Magnesium,
  • Selenium and
  • Zinc.

The comparator studies were inconsistent in finding differences with CD populations;
Vitamin D, the most reported nutrient, was only lower than the HC in one-quarter of the studies.
Adult CD populations are likely to contain individuals with low levels of one or more micronutrients, with the most substantial evidence for Vitamins D and B12. The studies on other micronutrients are of insufficient number, standardisation and quality to inform practice.

Effectiveness of Vitamin D Supplementation on Disease Course in Inflammatory Bowel Disease Patients: Systematic Review With Meta-Analysis
Inflamm Bowel Dis . 2022 Dec 29;izac253. doi: 10.1093/ibd/izac253

Background: The vitamin D role in bone metabolism is well known; however, recent evidence suggests the impact of vitamin D in immune modulation and its implications in immune-mediated diseases, including inflammatory bowel disease (IBD).

Method: We performed a systematic review with meta-analysis by a specific protocol (PROSPERO: CRD42022311184; March 2022, https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=311184). Randomized clinical trials involving IBD patients treated with vitamin D supplementation, compared with placebo, that evaluated the risk of clinical relapse and disease activity were included. Literature search was performed using Medline, Scopus, and Cochrane CENTRAL through January 2022.

Results: Out of 1448 articles, 12 (11 full-texts and 1 abstract) were included. Seven randomized clinical trials reported data on the clinical relapse as dichotomous outcome, while 7 studies reported data on disease activity expressed as continuous variables. The pooled risk ratio of clinical relapse was 0.64 (95% confidence interval, 0.46-0.89; I2 = 25%) among 458 IBD patients. However, this seems to be solid only in Crohn's disease (CD) patients. In fact, only 2 studies, involving 67 patients with ulcerative colitis, were included in the analysis. CD patients in clinical remission had a strong significant risk reduction in clinical relapse (risk ratio, 0.47; 95% confidence interval, 0.27-0.82; I2 = 0%), suggesting that it could be a specific subgroup with maximum clinical benefit of vitamin D supplementation.

Conclusions: This meta-analysis shows that vitamin D supplementation can reduce the risk of clinical relapse in IBD patients, especially in CD patients in clinical remission. In a subgroup analysis, it was not significant (due to small number of studies and low number of patients), and well-powered studies are needed, in particular for ulcerative colitis patients.

VitaminDWiki - Overview Gut and vitamin D contains gut-friendly information

Gut-friendly, Sublingual, injection, topical, UV, sunshine

Getting Vitamin D into your body has the following chart

Getting Vitamin D into your body also has the following
If poorly functioning gut
Bio-D-Mulsion Forte – especially made for those with poorly functioning guts, or perhaps lacking gallbladder
Sublingual – goes directly into the bloodstream
   you can make your own sublingual by dissolving Vitamin D in water or use nano form
Oil: 1 drop typically contains 400 IU, 1,000 IU, or 4,000 IU, typically not taste good
Topical – goes directly into the bloodstream. Put oil on your skin, Use Aloe vera cream with Vitamin D, or make your own
Vaginal – goes directly into the bloodstream. Prescription-only?
Bio-Tech might be usefulit is also water-soluble
Vitamin D sprayed inside cheeks (buccal spray) - several studies
    and, those people with malabsorption problems had a larger response to spray
Inject Vitamin D quarterly into muscle, into vein, or perhaps into body cavity if quickly needed
Nanoparticles could be used to increase vitamin D getting to the gut – Oct 2015
Poor guts need different forms of vitamin D has the following
