# Citrulline Blood Flow Randomized Trial: What the Evidence Says

## Quick Answer

Citrulline Blood Flow Randomized Trial has 1 source documents in the current Migaku evidence database. The strongest available sources in this first pass are mixed biomedical and public-health sources, 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 research article.
- 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 |
| --- | --- | ---: | --- | --- |
| Acute effect of citrulline malate on flow-mediated dilation and serum pharmacodynamics in healthy young males | research article | 4 | 2026-03-06 | 10.3389/fphys.2026.1773582 |

## What The Sources Report

- Gonzalez and Trexler, 2020 Gonzalez et al., 2023 Gonzalez et al., 2023 Figueroa et al., 2020 Gonzalez and Trexler, 2020 Gonzalez et al., 2023 Gough et al., 2021 L-citrulline is a non-essential and non-proteogenic amino acid found primarily in watermelon that functions as a precursor of L-arginine. [Grannes Johan (2026); evidence level 4]
- Malate, an intermediate in the citric acid cycle, is thought to potentially enhance ATP production, though this has not been substantiated by experimental evidence. [Grannes Johan (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

For citrulline blood flow randomized trial, the current source set is useful for orientation, but it is not yet broad enough for strong claims. Use cautious language and keep conclusions close to the cited sources.

## 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.
