Is Citrulline Hydration Exercise Randomized Trial safe?

Updated July 2026

Quick Answer

Citrulline Hydration Exercise Randomized Trial has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources. One representative finding is: Background: Post-COVID-19 syndrome is associated with endothelial dysfunction (ED) and various sequelae, particularly in individuals who experienced critical illness during the acute phase, affecting lung function and the musculoskeletal system.

Key Takeaways

  • 01Background: Post-COVID-19 syndrome is associated with endothelial dysfunction (ED) and various sequelae, particularly in individuals who experienced critical illness during the acute phase, affecting lung function and the musculoskeletal system. [Fernanda SM (2026)]
  • 02Conclusions: L-citrulline supplementation for three months decreased ICAM-1 and increased 6MWT. [Fernanda SM (2026)]
  • 03L-citrulline, a nonessential amino acid, has been shown to improve endothelial function, systemic inflammation, blood pressure, and physical performance. [Fernanda SM (2026)]
  • 04Next, we integrate evidence on the ergogenic effects of various dietary interventions with existing knowledge on the perception of effort. [Strasser B (2026)]
The current Migaku evidence database contains 2 reusable source documents for Citrulline Hydration Exercise Randomized Trial. This answer focuses on safety, limits, and clinician-discussion contexts. - Background: Post-COVID-19 syndrome is associated with endothelial dysfunction (ED) and various sequelae, particularly in individuals who experienced critical illness during the acute phase, affecting lung function and the musculoskeletal system. [Fernanda SM (2026); evidence level 2] - Conclusions: L-citrulline supplementation for three months decreased ICAM-1 and increased 6MWT. [Fernanda SM (2026); evidence level 2] - L-citrulline, a nonessential amino acid, has been shown to improve endothelial function, systemic inflammation, blood pressure, and physical performance. [Fernanda SM (2026); evidence level 2] - Next, we integrate evidence on the ergogenic effects of various dietary interventions with existing knowledge on the perception of effort. [Strasser B (2026); evidence level 4] - Beta-alanine, caffeine or carbohydrate mouth rinsing are examples of evidence-based ergogenic aids. [Strasser B (2026); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational. People with medical conditions, pregnancy, medication use, or unusual symptoms should ask a qualified clinician before changing supplements, medication, or treatment routines.
