## Key Takeaways

- This page is generated only from sources stored in the Migaku evidence knowledge base.
- Current evidence mix: 1 narrative review, 1 preclinical study.
- 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.

## What The Sources Report

- However, in the absence of sufficient oxygen, pyruvate is shunted to the lactic acid cycle where it is reduced to lactate. [Rosewarne Rowan E. (2026); evidence level 3]
- This pathway is essential to produce reduced nicotinamide adenine dinucleotide-phosphate (NADPH), which is used for many functions within the body like synthesis of fatty acids, maintenance of myelin sheaths, nerve membrane function, and transmission. [Rosewarne Rowan E. (2026); evidence level 3]
- The etiology of fatigue in IBD is multifactorial and may be associated with inflammation, anemia, nutrient deficiencies, medications, and microbiota. [MORAIS Tayane (2026); evidence level 4]
- Fatigue in patients with IBD is associated with decreased physical functioning, mood disturbances, and low productivity, presenting symptoms of physical and mental exhaustion. [MORAIS Tayane (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 thiamine supplementation fatigue meta-analysis, 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.
