Cystic Fibrosis and Vitamin D review with 2012 Guidelines - Nov 2019
Cystic Fibrosis got some benefit from 50,000 IU of vitamin D weekly (need gut-friendly form) – Feb 2018
Vitamin D has been recommended for Cystic Fibrosis – a small dose helps a little – Aug 2018
Cystic Fibrosis guidelines for Australia include Vitamin D – June 2019
Cystic Fibrosis exacerbation reduced by Vitamin D (250,000 IU) – RCT May 2017
Review of Cystic Fibrosis and Vitamin D PDF file, not web page: has the following
Cystic Fibrosis category listing has 52 items along with related searches
- "Cost of conventional Cystic Fibrosis tratment is $16,000/year"
- it will be a while until the doctors are willing to lose money with Vitamin D and/or Omgea-3
Cystic Fibrosis not helped by 50,000 IU of Vitamin D taken twice a month – RCT Feb 2019
- 50,000 IU every 2 weeks raised blood levels by only a tiny amount (~5 ng/ml)
- Clearly the type of vitamin D used was not getting into the blood stream, and so provided very little help

Better types of Vitamin D are sometimes needed

Overview Gut and vitamin D contains gut-friendly information
|Inhaled Vitamin D
Powder-based Vitamin D may be gut-friendly (Cystic Fibrosis) – RCT Aug 2017
Topical Vitamin D provides more benefits than oral sometimes - many studies - as of Oct 2019:: Preeclampsia. Food Allergy, PTSD, Ear infection, Infertility, MS, Colon Cancer, TB, Asthma, COPD, Epilepsy, Atrial Fibrillation. Liver, Also suspect for those people with poor guts: Cystic Fibrosis, Diabetes

Omega-3 also helps

Cystic fibrosis problems cut in half by Omega-3 – RCT June 2015

Vitamin D may also PREVENT Cystic Fibrosis

Vitamin D deficiency is a common finding in individuals with cystic fibrosis (CF), despite routine supplementation. Hypovitaminosis D is often the result of fat malabsorption, but other contributors include increased latitude, poor nutritional intake, decreased sun exposure, impaired hydroxylation of vitamin D, and non-adherence to the prescribed vitamin D regimen. Vitamin D is critical for calcium homeostasis and optimal skeletal health, and vitamin D deficiency in CF can lead to skeletal complications of osteopenia and osteoporosis.
Over time, our understanding of treatment regimens for vitamin D deficiency in CF has evolved, leading to recommendations for higher doses of vitamin D to achieve target levels of circulating 25-hydroxyvitamin D.
There is also some evidence that vitamin D deficiency may have non-skeletal consequences such as an increase in pulmonary exacerbations.
The exact mechanisms involved in the non-skeletal complications of vitamin D deficiency are not clearly understood, but may involve the innate immune system. Future clinical studies are needed to help address whether vitamin D has a role in CF beyond skeletal health.
