# Probiotic Psoriasis Meta-analysis: What the Evidence Says

## Quick Answer

Probiotic Psoriasis 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 narrative review.
- 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 |
| --- | --- | ---: | --- | --- |
| Effect of Probiotic and Synbiotic Oral Supplementation in Autoimmune Diseases: An Updated Systematic Review and Meta-Analysis of Randomized Controlled Trials | systematic review | 1 | 2026-03-30 | 10.3390/nu18071107 |
| The Effectiveness of Probiotics in Psoriasis: An Umbrella Review | narrative review | 3 | 2026-04-17 | 10.1155/jnme/1120062 |

## What The Sources Report

- The global prevalence of autoimmune diseases has been estimated at around 5-10% of the population, with some evidence indicating a rising trend, especially in industrialized nations. [Chiou Yuan-Yow (2026); evidence level 1]
- The cost associated with autoimmune diseases includes direct expenses such as medications, hospitalizations, and physician visits, and indirect costs like loss of productivity and reduced work capacity. [Chiou Yuan-Yow (2026); evidence level 1]
- Although the overall trends were declining, the burden among those aged 30-39 has increased, which potentially reduces the performance and economic contribution of this productive age group. [Ayuningtyas Maulidah (2026); evidence level 3]
- The need to conduct an umbrella review to identify, evaluate and synthesize the evidence is warranted, as there are numerous systematic reviews that assess the probiotics and psoriasis symptom relief. [Ayuningtyas Maulidah (2026); evidence level 3]

## 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 probiotic psoriasis 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.
