# Selenium Immune Meta-analysis: What the Evidence Says

## Quick Answer

Selenium Immune Meta-analysis has 2 source documents in the current Migaku evidence database. The strongest available sources in this first pass are systematic review, 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: 1 systematic 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.

| Effects of micronutrient supplementation on immune function in older adults: a meta-analysis | systematic review | 1 | 2026-05-22 | 10.3389/fimmu.2026.1732861 |

## What The Sources Report

- These immunological changes significantly contribute to increased morbidity, mortality, and healthcare costs among older adults. [Li Die (2026); evidence level 1]
- Furthermore, immunosenescence is exacerbated by poor nutrition, particularly micronutrient deficiencies, which are common in the elderly due to reduced food intake, metabolic changes, and disease. [Li Die (2026); evidence level 1]
- 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

There is at least one systematic-review style source in the current set, so it deserves more weight than single-study evidence. For selenium immune meta-analysis, the next editorial step is to add more targeted sources and separate strong findings from early or indirect evidence.

## 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.
