Between 40% and 80% of patients with these conditions have insufficient vitamin D levels, with deficiency associated with higher disease activity, fatigue, pain, and poorer musculoskeletal outcomes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f241f77 elementor-widget elementor-widget-text-editor\" data-id=\"f241f77\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Supplementation consistently corrected deficiency safely and showed modest benefits in disease activity in some patients, particularly those with low baseline vitamin D levels. However, evidence across studies was heterogeneous and inconsistent. Critically, large randomised trials and Mendelian randomisation studies did not confirm a causal relationship between vitamin D status and disease onset or sustained remission.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-bcdb794 elementor-widget elementor-widget-text-editor\" data-id=\"bcdb794\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>The authors recommend maintaining serum 25-hydroxyvitamin D concentrations of at least 30 ng\/mL for skeletal and muscular health, in line with existing IOF guidance, but conclude that supplementation should not be considered a stand-alone disease-modifying intervention.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-65630bd elementor-widget elementor-widget-text-editor\" data-id=\"65630bd\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Several questions remain unresolved, including whether vitamin D deficiency directly contributes to disease mechanisms or primarily reflects chronic inflammation, the optimal serum thresholds for immune modulation, and the long-term safety of higher-dose supplementation strategies. The authors call for larger, well-designed randomised trials that stratify patients by baseline deficiency and genetic background to clarify causal mechanisms and long-term effects.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-bb5aaf1 elementor-widget elementor-widget-text-editor\" data-id=\"bb5aaf1\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Source: <em>Messina OD et al.
