Filter by:Vitamin D deficiency is common among pregnant women, despite daily vitamin D supplements. This study aims to investigate if maternal vitamin D intake of 90 vs 10 µg affects the overall health, growth, and immune system of the offspring at birth and after 1 year. Blood samples at birth and after one year, questionnaires and clinical 1-year examination will be performed on the children.
Non-systematized chronic musculoskeletal pains are a frequent reason for consulting in general practice. The possible causes are numerous and sometimes nonspecific. In some cases, the etiologic investigation of patients with non-systematized and chronic musculoskeletal pain can not highlight any organic cause. Several studies have shown a link between these symptoms and vitamin D deficiency, characterized by a blood level of 25 (OH) vitamin D < 20.8ng/ml. This deficit is easy to identify and to correct through proper vitamin D supplementation with few side effects. Nevertheless, it remains unknown and vitamin D deficiency is rarely considered as a possible etiology in patients with chronic pain. We hypothesize that vitamin D supplementation in patients with non-systematized musculoskeletal pain and deficient in vitamin D could improve painful symptoms. We aim to perform a double-blind randomized controlled trial, vitamin D versus placebo, to assess the pain improvement after vitamin D supplementation.
