The Preventive Role of Vitamin D in the Prevention and Management of Fibromyalgia Syndrome

Abstract

Aim: Vitamin D deficiency is a prevalent condition among the general population, all around the world. Vitamin D deficiency is defined as serum levels of 25-hydroxy vitamin D lower than 20 ng/ml (50 nmol/ml). It is a known actor in the skeletal system through the regulation of calcium and phosphate metabolism and bone mineralization. Still, the role of vitamin D as an immunomodulator is yet to be acknowledged by healthcare practitioners as a cause, precipitating factor, and contributor to a variety of diseases. Vitamin D is shown to be an actor in multiple sclerosis, rheumatoid arthritis, insulin-dependent diabetes mellitus, and irritable bowel syndrome. Fibromyalgia syndrome (FMS) is a chronic disorder associated with a severe pain that can affect a patient's musculoskeletal system, daily routine, and mood. The clinical presentation encapsulates other disorders such as lethargy and sleep problems, brain fog and other cognitive issues, and physical and psychiatric symptoms. Methods: We have used PubMed and ResearchGate in the reviewing process of our paper. We tried to address as many topics as we judged to be adequate and relevant for the practicing clinicians. Results: Management of fibromyalgia syndrome is both nonpharmacologic and pharmacologic, which are provided in a stepwise fashion. Yet, the management of FMS remains a challenge, heeding a multidisciplinary approach. Among the dietary interventions, we chose vitamin D and its effects on FMS. Literature shows that supplementation improves pain caused by fibromyalgia syndrome, yet specific recommendations are still to be created. Conclusions: We call on all the relevant governmental bodies, public health experts and health policy makers, healthcare practitioners, and the civil society to use novel data related to fibromyalgia syndrome, and in a broader perspective, the integral role of vitamin D.
