- Children short sleep 12 percent more likely for each 1 ng lower vitamin D at birth – Oct 2018
- Poor sleep 1.5 X more likely if less than 20 ng of Vitamin D – meta-analysis Oct 2018
- Sleep half hour longer if OK level of Vitamin D (2-year olds) – April 2018
- Poor sleep if low Vitamin D, Magnesium, or Vitamin B6 (NHANES) – June 2019
Sleep category starts with
A few items in SLEEP category
- Sleep greatly improved by 50,000 IU of vitamin D once every two weeks – RCT Sept 2018
- Sleep disorders nicely treated by Vitamin D (50,000 IU twice a month) – RCT May 2017
- Sleep, Dr. Gominak and Vitamin D - several studies
- Restless Legs Syndrome dramatically reduced by vitamin D, etc
- On the job sleepiness 2.2X more likely if low vitamin D – Feb 2020
- Poor sleep 1.5 X more likely if less than 20 ng of Vitamin D – Feb 2019
- The Better Sleep Vitamin (Vitamin D) – nice 3 dollar book Feb 2015
- The worse the sleep apnea, the lower the vitamin D levels – meta-analysis 2017, 2020
- Vitamin D for better sleep video - Dec 2021
- 5X increase in sleep problems in a decade in US Veterans
- Sleep Apnea and Vitamin D - many studies
- Melatonin and Vitamin D - many studies does much more than improve sleep

BACKGROUND:
The association between low 25-hydroxyvitamin D [25(OH)D] and sleep disorder has been reported. We investigated whether serum concentrations of 25(OH)D are altered in chronic insomnia patients. The relationship between serum concentrations of 25(OH)D and the treatment outcome in patients at 2months was also investigated.
METHODS:
In total, 181 chronic insomnia patients were consecutively recruited. All patients received pharmacotherapy for the treatment of chronic insomnia. Serum 25(OH)D concentrations were quantified by a competitive electrochemiluminescence protein binding assay. Treatment outcomes were defined as "response" versus "non-response", according to the change of the Pittsburgh Sleep Quality Index (PSQI). We also recruited 100 healthy subjects as a control group.
RESULTS:
Fifty-four out of 181 (29.8%) patients met the criteria for non-response. Chronic insomnia patients had significantly lower 25(OH)D concentrations compared with healthy controls (23.01±9.18 vs 27.17±6.41ng/ml, P<0.001). Non-response patients also had significantly lower 25(OH)D concentrations than those with response. Vitamin D deficiency(25(OH)D concentrations<20ng/ml) was independently associated with a higher probability of treatment non-response at 2 months (odds ratio 11.636, 95% confidence interval 3.966-34.142, P<0.001).
CONCLUSIONS:
Measurement of serum 25(OH)D concentrations are probably useful for judging treatment outcomes of pharmacotherapy in chronic insomnia patients.
