# Citrulline Recovery Randomized Trial: What the Evidence Says

## Quick Answer

Citrulline Recovery Randomized Trial has 2 source documents in the current Migaku evidence database. The strongest available sources in this first pass are randomized trial, 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 randomized trial.
- 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

- It is characterized by the reduction in endothelial nitric oxide synthase, resulting in reduced nitric oxide (NO) availability. [Fernanda Salgado-Fernández María (2026); evidence level 2]
- In individuals who have recovered from COVID-19, elevated concentrations of markers indicative of endothelial damage have been observed, including endothelin-1 (ET-1), a potent vasoconstrictor that is expressed under conditions associated with endothelial cell injury, has been linked to the development of pulmonary damage and is a possible marker of poor prognosis. [Fernanda Salgado-Fernández María (2026); evidence level 2]
- Strategies that support repeated high-intensity sprint performance are of considerable interest in competitive sprinting and team sports; however, evidence regarding acute citrulline malate (CM) supplementation during recovery intervals remains limited. [Yamanaka R (2026); evidence level 2]
- This study examined the effects of acute CM supplementation on repeated 100 m sprint performance and rating of perceived exertion (RPE) in trained sprinters. [Yamanaka R (2026); evidence level 2]

## 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 trial evidence in the current set, but population and intervention details still matter. For citrulline recovery 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.
