# Maca Fatigue Meta-analysis: What the Evidence Says

## Quick Answer

Maca Fatigue 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.

## Evidence Map

| Source | Evidence type | Level | Date | Identifier |
| --- | --- | ---: | --- | --- |
| Herbal dietary supplements for erectile dysfunction: A systematic review and meta-analysis of randomized-controlled trials | systematic review | 1 | 2026-01-01 | 10.1016/j.jtcme.2025.11.001 |
| Nutritional Interventions and Acupuncture‐Based Strategies for Exercise‐Induced Fatigue and Recovery: Mechanisms and Integrative Perspectives | preclinical study | 4 | 2026-05-15 | 10.1002/fsn3.71871 |

## What The Sources Report

- In general, risk of bias in selective reporting and incomplete data were low, and bias regarding inclusion of intention-to-treat analysis was low to moderate. [Ho Chao-Yen (2026); evidence level 1]
- The analysis revealed a pooled SMD (pSMD) = 1.20 (95 % confidence interval [CI]: 0.64 to 1.76), indicating that taking herbal dietary supplements was associated with a greater improvement in erectile function as compared to controls. [Ho Chao-Yen (2026); evidence level 1]
- Comprehensive descriptions of the mechanisms underlying central fatigue can be found in recent reviews (Zhou et al. ). [Yang Yaqin (2026); evidence level 4]
- In addition, reduced oxidative phosphorylation capacity, loss of mitochondrial membrane potential, and accumulation of damaged mitochondria compromise ATP supply and exacerbate ROS generation (Powers et al. ; Yu et al. ). [Yang Yaqin (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 maca fatigue 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.
