# Astaxanthin Exercise Performance Randomized Trial: What the Evidence Says

## Quick Answer

Astaxanthin Exercise Performance Randomized Trial 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: 2 systematic 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.

## What The Sources Report

- Astaxanthin significantly reduced creatine kinase levels (SMD = -0.45, 95% CI: -0.83 to -0.07). [Liu S (2026); evidence level 1]
- Conclusions: Current evidence suggests that astaxanthin may be more beneficial for post-exercise recovery than for direct performance enhancement. [Liu S (2026); evidence level 1]
- Algae supplementation showed a suggestive improvement in VO 2 max (SMD = 0.88, 95% CI: 0.00-1.75) and significantly improved in TTE (SMD = 1.06, 95% CI: 0.16-1.96), with smaller effects on WRmax (SMD = 0.29, 95% CI: 0.03-0.55), and no significant benefit for TT performance (SMD = -0.27, 95% CI: -0.74 to 0.21). [Wei Y (2026); evidence level 1]
- Regarding recovery, CK concentrations were significantly reduced (SMD = -0.78, 95% CI: -1.28 to -0.28). [Wei Y (2026); evidence level 1]

## 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 astaxanthin exercise performance randomized trial, 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.
