Many CF candidates were rejected from the trial, probably due to already taking Vitamin D

1.6X as many were rejected due to Vitamin D than were accepted (149 vs 91
Speculation: Those who were accepted tended to be those who had previously found that
standard Vitamin D without Magnesium did not help their CF

Cystic Fibrosis patients often have gut absorption problens,
so need higher doses or different forms of Vitamin D, such as:


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 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 usefulit 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

Left Chart: Poor response to 250,000 IU Loading Dose
CFers are known to have poor absorption of fat-soluable Vitamins (D, K, etc)
Most people with good guts would have ((Large dose of vitamin D (200,000 IU) lasts for about 100 days – Feb 2015
The effect of a single, large bolus of vitamin D in healthy adults over the winter and following year|>40 ng response to such a loading dose))
Right Chart: Poor response to 50,000 IU every 2 weeks Maintenance Dose
This would typically result in 40 ng/ml blood response
CFers clearly have far lower bio-availability to this oral vitamin D


BACKGROUND:
Patients with cystic fibrosis (CF) have increased risk of vitamin D deficiency owing to fat malabsorption and other factors. Vitamin D deficiency has been associated with increased risk of pulmonary exacerbations of CF.

OBJECTIVES:
The primary objective of this study was to examine the impact of a single high-dose bolus of vitamin D3 followed by maintenance treatment given to adults with CF during an acute pulmonary exacerbation on future recurrence of pulmonary exacerbations.

METHODS:
This was a multicenter, double-blind, placebo-controlled, intent-to-treat clinical trial. Subjects with CF were randomly assigned to oral vitamin D3 given as a single dose of 250,000 International Units (IU) or to placebo within 72 h of hospital admission for an acute pulmonary exacerbation, followed by 50,000 IU of vitamin D3 or an identically matched placebo pill taken orally every other week starting at 3 mo after random assignment. The primary outcome was the composite endpoint of the time to next pulmonary exacerbation or death within 1 y. The secondary outcomes included circulating concentrations of the antimicrobial peptide cathelicidin and recovery of lung function as assessed by the percentage of predicted forced expiratory volume in 1 s (FEV1%).

RESULTS:
A total of 91 subjects were enrolled in the study. There were no differences between the vitamin D3 and placebo groups in time to next pulmonary exacerbation or death at 1 y. In addition, there were no differences in serial recovery of lung function after pulmonary exacerbation by FEV1% or in serial concentrations of plasma cathelicidin.

CONCLUSIONS:
Vitamin D3 initially given at the time of pulmonary exacerbation of CF did not alter the time to the next pulmonary exacerbation, 12-mo mortality, serial lung function, or serial plasma cathelicidin concentrations. This trial was registered at clinicaltrials.gov as NCT01426256.
