L-Citrulline

L-Citrulline is an amino acid that plays a role in the urea cycle, helping to remove ammonia from the body and is a precursor to L-arginine, which is used to produce nitric oxide. Nitric oxide is important for cardiovascular health as it helps to relax blood vessels and improve blood flow, potentially supporting heart health and exercise performance.

Research on L-Citrulline includes varying focuses, from its pharmacokinetics to its potential therapeutic effects.

  1. Pharmacokinetics Study: A study on neonatal Holstein calves (2026) evaluated the pharmacokinetics and short-term tolerability of both intravenous and oral L-Citrulline. This investigation helps in understanding how this compound is processed in the body, potentially informing dosing and delivery methods.

  2. Oxidative Stress: Research published in Cellular Signalling (2026) highlighted L-Citrulline's potential in reducing oxidative stress-induced damage in nucleus pulposus cells by inhibiting inflammasome assembly. This suggests L-Citrulline could have a cellular protective role.

  3. Clinical Trials:

    • Sepsis: A clinical trial (NCT02370030) explored how Citrulline might impact biochemical progression in sepsis patients, although the current status is unknown.
    • Small Bowel Toxicity: Another completed trial (NCT01849107) investigated plasma Citrulline as a biomarker for radiation-induced small bowel toxicity, suggesting its potential for monitoring radiation effects.
    • Adolescents with MASLD: A completed trial (NCT05778266) examined the effects of L-Citrulline combined with high-intensity interval training on arterial stiffness, body composition, and lipid profile in adolescents with metabolic-associated steatosis.

This body of work illustrates a growing interest in understanding L-Citrulline's various roles and potential benefits in different medical and physiological contexts. However, more targeted research in humans is necessary to fully elucidate its therapeutic applications.
