Background: Several studies have shown that vitamin D supplementation could be useful for treating diffuse musculoskeletal (DMS) pain in adults.
Objectives: The aim of this study was to evaluate the effects of correcting a vitamin D deficiency (≤ 50 nmol/l) on DMS pain and quality of life in adults.
Methods: A pragmatic prospective study was conducted in a general practice setting in the Rhone-Alps area between 1 February and 30 April 2009. Patients between the ages of 18 and 50 years old who consulted their general practitioner (GP) for DMS pain or chronic unexplained asthenia and had a deficient serum 25 (OH) D level with no signs of any other disease were enrolled in this study. The patients received high doses of vitamin D supplements (400 000 to 600 000 units). Mean pain evaluation scores were evaluated before and after vitamin D supplementation using mixed models and accounting for repeated measures.
Results: Before vitamin D supplementation, the adult study cohort (n = 49) had an adjusted mean serum 25 (OH) D level of 23.7 nmol/l, a mean pain evaluation score of 5.07 and a mean quality of life score of 3.55. After vitamin D supplementation, the adjusted mean serum 25 (OH) D level increased to 118.8 nmol/l (P < 0.001), the mean quality of life score increased to 2.8 nmol/l (P < 0.001) and the mean pain evaluation score decreased to 2.8 (P < 0.001). Conclusion: In this small before-and-after study, vitamin D supplementation decreased pain scores in adult patients with diffuse musculoskeletal pain and vitamin D deficiency. These results must be confirmed by further studies.

Previously published in French April 2013, which has the following conclusion
The correction of vitamin D deficiency resulted in a significant decrease in the level of pain intensity according to
- verbal rating scale (P=0.034) and the
- Digital Scale (P<0.001),
- consumption of analgesics (P=0.002) and
- discomfort in carrying out activities of daily living following: the shopping, cleaning,
- walking for more than a kilometer (P<0.001) and
- dressing (P=0.012)
Summary by Vitamin D Life of adding 400,000 IU of vitamin D
Before | After | |
Vitamin D level | 10 ng | 46 ng |
Pain score | 5.1 | 2.8 |
Quality of life | 3.6 | 2.8 ? |
Note: The abstract gives Quality of Life in units of nmol/liter, which is incorrect, and the number should be higher than 3.6
