Evidence Map

What The Sources Report

• Selenium (Se), a trace mineral the body needs only in tiny amounts to stay healthy, is found in many animal- and plant-based foods. [Persani Luca (2026); evidence level 4]
• A recent systematic review and meta-analysis found no difference in B12 levels between patients with subclinical hypothyroidism and those with hyperthyroidism, whereas hypothyroid patients had lower B12 levels than healthy adults. [Persani Luca (2026); evidence level 4]
• It is associated with elevated anti-thyroid peroxidase antibodies (TPOAb) and often anti-thyroglobulin antibodies (TgAb). [Personius Lydia (2026); evidence level 4]
• The incidence of HT has increased over recent decades and is higher with advancing age, in women, and in iodine-sufficient populations. [Personius Lydia (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 selenium 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.
