Muscle Pain Might be Related to Vitamin D Deficiency
A cross-sectional study was conducted on 150 patients with nonspecific musculoskeletal pain. Researchers measured the calcidoiol–an indicator of vitamin D ingestion–levels and found every patient to be vitamin D deficient. Out of the 150 patients, 28 percent had severely deficient vitamin D levels, 55 percent of who were younger than 30 years.
In another related study conducted in Saudi Arabia, researchers found vitamin D deficiency in a group of 360 chronic back patients. All the patients were given physiological doses of cholecalciferol for three months, which improved the chronic pain. Even though the doses they were given (5,000 to 10,000 IU) are said to be toxic (the American institute of Medicine says 3,800 IU is toxic) all the patients normalized their calcidiol levels.
