Impact of vitamin D on spirometry findings and quality of life in patients with chronic obstructive pulmonary disease: a randomized, double-blinded, placebo-controlled clinical trial
International Journal of Chronic Obstructive Pulmonary Disease Volume 2019:14 Pages 1495—1501, https://doi.org/10.2147/COPD.S207400
- COPD 2.8 times more likely to be severe if low vitamin D – meta-analysis Oct 2016
- COPD strongly associated with Vitamin D Binding Protein problems – meta-analysis Aug 2015
- COPD severity is associated with Vitamin D deficiency – meta-analyses 2015, 2019
- COPD reduced by 40 percent with monthly 100,000 IU of vitamin D – RCT Jan 2015
- COPD trial to use 80,000 IU of vitamin D weekly – RCT 2021
COPD fought by Vitamin D - many studies has the following
- Vitamin D is one of the alternate COPD therapies – March 2021
- COPD treated by Vitamin D – meta-analysis March 2022
- COPD quality of life improved by 400,000 IU Vitamin D loading dose – RCT July 2019
- COPD exacerbations 2X less often if low vitamin D then supplemented – meta-analysis Jan 2019
- Worse breathing with COPD is related to lower Vitamin D – June 2018
- COPD ICU stay is 2.4 days longer if low vitamin D – Oct 2015
- COPD and Vitamin D, concise (46 page) review – Dec 2016
- 100000 IU vitamin D monthly helps COPD patients – 3 RCT
- Those with Asthma or COPD had half the response to Vitamin D – March 2020
AND includes the following sections
50,000 IU weekly - 6X more likely to improve breathing - 2014
50,000 IU helped COPD in many ways - Jan 2015
COPD has become the 3rd largest global cause of disability: ages 50-69
Loading Dose
- Overview Loading of vitamin D
- Loading may be done as quickly as a single day, to as slowly as 3 months.
- It appears that spreading the loading dose over 4-20 days is a good compromise

COPD Assesment Test improved signifiantly after 2 month loading dose
and doubled that improvement after maintenance dosing of 6 months

COPD is an irreversible chronic illness with airflow limitation. The aim of the current study was to assess the role of vitamin D3 on quality of life and pulmonary function in patients with COPD. A randomized, double-blinded clinical trial was conducted in 63 patients with COPD. Patients were placed into intervention and placebo groups. Each individual in the intervention group took 50,000 IU vitamin D3 once a week for 8 weeks and then once a month for 4 months. There was no significant difference among FEV1, FEV1/FVC, and number of exacerbations in patients with COPD (P>0.05). In the intervention group, a significant difference was observed in quality of life at 2 months (P<0.001) and 6 months (P<0.001). In addition, qualitative analysis showed that the status of exacerbation had not got worse six months after initiation in the intervention group. The current study shows that consumption of 50,000 IU vitamin D3, as a convenient supplementation in a daily diet, is able to increase quality of life in patients with COPD.
