Does Vitamin D Fatigue Randomized Trial work?

The current Migaku evidence database contains 2 reusable source documents for Vitamin D Fatigue Randomized Trial. This answer focuses on strength of evidence and what the studies can or cannot prove. - Supplementation with B vitamins and magnesium improved fatigue and symptom-based disease activity scores in UC; however, effects on underlying inflammatory activity remain uncertain. [Ramezani E (2026); evidence level 4] - This study investigated the efficacy of supplementation with B vitamins and magnesium in alleviating fatigue, improving disease activity, and health-related quality of life (HRQoL) in patients with inflammatory bowel disease (IBD) based on patient-reported outcomes. [Ramezani E (2026); evidence level 4] - In this randomized, double-blind, placebo-controlled trial, 98 adults with IBD in remission were randomized (1:1) to receive daily supplementation with vitamins B 1 , B 6 , B 12 , and magnesium or a matching placebo for 4 weeks. [Ramezani E (2026); evidence level 4] - Perimenopausal women often experience fatigue and mood disturbances, which may be associated with vitamin D deficiency. [Ray P (2026); evidence level 4] - Therefore, it is of interest to investigate the effect of vitamin D supplementation on fatigue and mood in perimenopausal women with vitamin D deficiency. [Ray P (2026); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
