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
- Many intervention clinical trials for vitamin D to prevent or treat Gut problems (93 trials listed as of Jan 2017)
- All items in category gut and vitamin D
Overview Gut and vitamin D contains gut-friendly informationGut-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
Bio-D-Mulsion Forte – especially made for those with poorly functioning guts, or perhaps lacking gallbladder
Sublingual – goes directly into bloodstream
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
Guesses of Vitamin D response if poor gut
Bio Form Speed Duration 10 Injection: Vitamin D,
or Calcidiol or Calcitriol
Fast Long 10 Sun/UV Slow Long 10 Topical
(skin patch/cream, vagina)
Slow Normal 9? Inhaled (future) Fast Normal 8 Bio-D-Mulsion Forte Normal Normal 6 Water soluble (Bio-Tech) Normal Normal 5 Nanoemulsion
perhaps activates VDR
Normal Normal 4 Sublingual/spray
(some goes into gut)
Fast Normal 3 Coconut oil based Slow Normal 2 Food (salmon etc.) Slow Normal 2 Olive oil based (majority) Slow Normal
10= best bioavailable, 0 = worst, guesses have a range of +-2
Speed: Fast ~2-6 hours, Slow ~10-30 hours
Duration: Long ~3-6 months, Normal = ~2 months

BACKGROUND AND AIMS:
Vitamin D may be immunomodulatory and alter faecal microbiota, but results from clinical studies in humans to date have been inconclusive. This study aimed to assess the effect of vitamin D replacement in vitamin D-deficient patients with and without ulcerative colitis [UC] on inflammation and faecal microbiota.
Vitamin D was replaced over 8 weeks in patients with active UC [defined by faecal calprotectin ≥ 100 µg/g], inactive UC [faecal calprotectin < 100 µg/g] and non-inflammatory bowel disease [IBD] controls with baseline serum 25[OH] vitamin D <50 nmol/l, and markers of inflammation and faecal microbiota were analysed.
Eight patients with active UC, nine with inactive UC and eight non-IBD controls received 40000 units cholecalciferol weekly for 8 weeks. Mean baseline 25[OH] vitamin D increased from 34 [range 12-49] to 111 [71-158] nmol/l [p < 0.001], with no difference across the groups [p = 0.32]. In patients with active UC, faecal calprotectin levels decreased from a median 275 to 111 µg/g [p = 0.02], platelet count decreased [mean 375 to 313 × 109/l, p = 0.03] and albumin increased [mean 43 to 45 g/l, p = 0.04]. These parameters did not change in patients with inactive UC or non-IBD controls. No changes in overall faecal bacterial diversity were noted although a significant increase in Enterobacteriaceae abundance was observed in patients with UC [p = 0.03].
Vitamin D supplementation was associated with reduced intestinal inflammation in patients with active UC, with a concomitant increase in Enterobacteriaceae but no change in overall faecal microbial diversity.
