Much more benefit when a drug can be delivered exactly to where it is needed
Much better than increasing Vitamin D levels for the entire body
Other examples for Vitamin D targeted delivery include topical for skin and oral for gums
Respiratory vitamin D (inhaled) looks very promising
Activated Vitamin D
- Active vitamin D appears to treat cancer – more studies needed – June 2018
- Natural Ways to Increase Calcitriol and Activate The Vitamin D Receptor Gene – Oct 2017
- Get active vitamin D by eating Solanum Glaucophyllum leaves – Sept 2013
- Calcitriol category listing has
43 items has the following chart
- IBS - many indications that Vitamin D will help - more research needed - March 2018
- Gut bacteria of Crohn's disease patients improved by Vitamin D – March 2018
- Perhaps activated Vitamin D helps both the gut and the gut bacteria
- 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

Spleen was not as enlarged with activiated vitamin D emulsion
The active form of vitamin D3, 1,25(OH)2D3 has been found to exert multiple effects on the suppression of progression of inflammatory bowel disease (IBD). Vitamin D3 has been gathering attention as a therapy for IBD. However, the clinical trials conducted to date revealed that a relatively high dosage of vitamin D3 was required to see a significant therapeutic effect. Thus, effective formulation and delivery of vitamin D3 to colonic inflammatory lesions will be required. Herein we describe the preparation of a nanostructured lipid carrier (NLC) for the encapsulation of 1,25(OH)2D3 for colonic delivery via oral administration. The optimized fabrication procedure enabled the incorporation of 1,25(OH)2D3 in the NLC by minimizing the destruction of chemically unstable 1,25(OH)2D3. The obtained NLCs orally delivered 1,25(OH)2D3 to the colon in mice and maintained a high concentration of 1,25(OH)2D3 in the colonic tissue for at least 12 h. The NLC showed multiple effects on the suppression of symptoms of colitis induced by dextran sodium sulfate, namely maintaining crypt structure, reducing the tissue concentration of inflammatory cytokines, suppressing the infiltration of polymorphonuclear leukocytes, and augmenting anti-inflammatory CX3CR1high macrophages. Our NLCs containing 1,25(OH)2D3 may be an alternative treatment for IBD therapy.
