Does L-Citrulline Endurance Randomized Trial work?

Updated October 2026

Quick Answer

L-Citrulline Endurance Randomized Trial has evidence relevant to strength of evidence and what the studies can or cannot prove, but conclusions should stay close to the cited sources. One representative finding is: Risk of bias, small-study effects, sensitivity analyses, and GRADE certainty were assessed.

Key Takeaways

  • 01Risk of bias, small-study effects, sensitivity analyses, and GRADE certainty were assessed. [Wang X (2026)]
  • 02CM supplementation was associated with a small improvement in overall exercise performance (g = 0.16, p = 0.01); however, prediction intervals were wide and statistical power was limited. [Wang X (2026)]
  • 03Current evidence appeared more stable for acute than chronic supplementation, although the protocol subgroup difference remained uncertain. [Wang X (2026)]
  • 04Background: Citrulline malate (CM) is commonly used as an ergogenic supplement, but its effects on exercise performance and perceived exertion remain uncertain. [Wang X (2026)]
The current Migaku evidence database contains 2 reusable source documents for L-Citrulline Endurance Randomized Trial. This answer focuses on strength of evidence and what the studies can or cannot prove. - Risk of bias, small-study effects, sensitivity analyses, and GRADE certainty were assessed. [Wang X (2026); evidence level 1] - CM supplementation was associated with a small improvement in overall exercise performance (g = 0.16, p = 0.01); however, prediction intervals were wide and statistical power was limited. [Wang X (2026); evidence level 1] - Current evidence appeared more stable for acute than chronic supplementation, although the protocol subgroup difference remained uncertain. [Wang X (2026); evidence level 1] - Background: Citrulline malate (CM) is commonly used as an ergogenic supplement, but its effects on exercise performance and perceived exertion remain uncertain. [Wang X (2026); evidence level 1] - Individual exercise tolerance is defined as the amount of physical exertion that can be sustained before task disengagement and can be increased through appropriate training strategies [,]. [Strasser Barbara (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.
