Role of micronutrients in the symptoms of fibromyalgia: a review of the literature and analysis of an Italian female sample.

OBJECTIVE

Fibromyalgia (FM) is a multifactorial disease characterized principally by chronic, widespread pain impairing a patient's quality of life. The management of FM requires a multidisciplinary approach that combines pharmacological and non-pharmacological strategies. Growing evidence suggests a potential beneficial role of micronutrients such as minerals and vitamins. Overall, the role of these supplements remains controversial, but clinical trials on vitamin D, vitamin B12, magnesium, and iron supplementation seem to provide promising results. The aim of this study was to investigate their role in an Italian female sample.

SUBJECTS AND

METHODS

An exploratory cross-sectional study was done to assess the association of selected micronutrients with symptoms of FM by using the Fibromyalgia Impact Questionnaire (FIQ) in twenty consecutive female patients with FM. A literature review was also conducted.

RESULTS

FIQ results revealed that vitamin D and magnesium deficiency appear to play a role in FM symptoms, mainly in physical function and stiffness. From the literature review, only two studies investigating the role of micronutrients in FM were retrieved.

CONCLUSIONS

Screening for micronutrient deficiencies in FM patients and supplementing them when levels are low might help counteract FM symptoms.
