- From PDF Cholecalciferol 20.000 IU daily from day 1 until day 3, then every second day for 4 weeks. In this study, we aimed for a target vitamin D level between 100 and 150 nmol/l. Serum 25-OH vitamin D levels were measured weekly (before administration = week 0). In both groups, 380.000 IU 25-OH vitamin D were administered per patient over the course of the study
- Crohn's Disease relapse rate of 3 in 8 with 1,000 IU vs 0 in 12 with 10,000 IU of Vitamin D – RCT Feb 2017
Overview Gut and vitamin D has the following summary
- Gut problems result in reduced absorption of Vitamin D, Magnesium, etc.
- Celiac disease has a strong genetic component.
- Most, but not all, people with celiac disease have a gene variant.
- An adequate level vitamin D seems to decrease the probability of getting celiac disease.
- Celiac disease causes poor absorption of nutrients such as vitamin D.
- Bringing the blood level of vitamin D back to normal in patients with celiac disease decreases symptoms.
- The prevalence of celiac disease, not just its diagnosis, has increased 4X in the past 30 years, similar to the increase in Vitamin D deficiency.
- Review in Nov 2013 found that Vitamin D helped

Getting Vitamin D into your body has the following chart
Getting Vitamin D into your body also has the following
Bio-D-Mulsion Forte – especially made for those with poorly functioning guts, or perhaps lacking gallbladder
Sublingual – goes directly into bloodstream
you can make your own sublinqual by dissovling Vitamin D in water or using nanoemulsion form
Oil: 1 drop typically contains 400 IU, 1,000 IU, or 4,000 IU, typically not taste good
Topical – goes directly into bloodstream. Put oil on your skin, Use Aloe vera cream with Vitamin D, or make your own
Vaginal – goes directly into bloodstream. Prescription only?
Bio-Tech might be useful – it is also water soluble
Vitamin D sprayed inside cheeks 2X more response (poor gut) – RCT Oct 2015
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

Speed: Fast ~2-6 hours, Slow ~10-30 hours
Duration: Long ~3-6 months, Normal = ~2 months
Dysbiosis is a common feature in the pathogenesis of inflammatory bowel diseases (IBD). Environmental factors, such as vitamin D deficiency, seem to play a role in the intestinal inflammation of IBD. The aim of this study was to investigate whether vitamin D administration has an impact on the bacterial composition in Crohn's disease (CD) compared to healthy controls (HC).
A prospective, longitudinal, controlled interventional analysis was conducted in seven patients with CD in clinical remission and 10 HC to investigate the effect of orally administrated vitamin D on the intestinal bacterial composition using 16S ribosomal RNA gene amplicon sequencing. Clinical parameters were assessed.
In contrast to HC, microbial communities of CD patients changed significantly during early vitamin D administration. However, a further increase in vitamin D level was associated with a reversal of this effect and additionally with a decrease in the bacterial richness in the CD microbiome. Specific species with a high abundancy were found during vitamin D administration in CD, but not in HC; the abundancy of Alistipes, Barnesiella, unclassified Porphyromonadaceae (both Actinobacteria), Roseburia, Anaerotruncus, Subdoligranulum and an unclassified Ruminococaceae (all Firmicutes) increased significantly after 1‐week vitamin D administration in CD.
Vitamin D has a specific influence on the bacterial communities in CD, but not in HC. Administration of vitamin D may have a positive effect in CD by modulating the intestinal bacterial composition and also by increasing the abundance of potential beneficial bacterial strains.Gut bacteria of Crohn's disease patients improved by Vitamin D – March 2018
