# Vitamin D Fatigue Randomized Trial: What the Evidence Says

## Quick Answer

Vitamin D Fatigue Randomized Trial has 2 source documents in the current Migaku evidence database. The strongest available sources in this first pass are mixed biomedical and public-health sources, so conclusions should be framed as evidence-aware guidance rather than medical advice.

## Key Takeaways

- This page is generated only from sources stored in the Migaku evidence knowledge base.
- Current evidence mix: 2 research article.
- Claims should be interpreted with the source type, study design, population, and publication date in mind.
- This article is educational and does not replace care from a qualified clinician.

## Evidence Map

| Source | Evidence type | Level | Date | Identifier |
| --- | --- | ---: | --- | --- |
| Effects of B vitamins and magnesium on fatigue, disease activity and quality of life in inflammatory bowel disease. | research article | 4 | 2026-04-21 | 10.1038/s41598-026-49880-7 |
| Effect of vitamin D supplementation on fatigue and mood among perimenopausal women. | research article | 4 | 2026-03-31 | 10.6026/973206300221638 |

## What The Sources Report

- 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]
- 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]

## How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

## Practical Interpretation

For vitamin D fatigue randomized trial, the current source set is useful for orientation, but it is not yet broad enough for strong claims. Use cautious language and keep conclusions close to the cited sources.

## Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
